How to receive and store CURL username with PHP - php

I have the command:
curl -k -u **username:password** --request POST -H "Content-Type:application/json" -d "{\"name\":\"John\",\"age\":\"31\",\"test\":\"New York\"}" http://siteteste.com/receive.php
I want to get the server-side username and password with PHP.
I am using the POST method.
My PHP:
<?php
// Only allow POST requests
***// I want the username and password here with PHP POST.***
***$user = $_POST[""]; // Not working :(***
if (strtoupper($_SERVER['REQUEST_METHOD']) != 'POST') {
throw new Exception('Only POST requests are allowed');
}
// Make sure Content-Type is application/json
$content_type = isset($_SERVER['CONTENT_TYPE']) ? $_SERVER['CONTENT_TYPE'] : '';
if (stripos($content_type, 'application/json') === false) {
throw new Exception('Content-Type must be application/json');
}
// Read the input stream
$body = file_get_contents("php://input");
// Decode the JSON object
$object = json_decode($body, true);
// Throw an exception if decoding failed
if (!is_array($object)) {
throw new Exception('Failed to decode JSON object');
}
// Display the object
$getit = $object['test'];
print $getit;
How can I do it?
I try, but not working.
I search StackOverflow and others site, but not found informatio

Your body is json-encoded.
You will get your data here:
$body = file_get_contents("php://input");
// Decode the JSON object
$object = json_decode($body, true);
var_dump($object); // <-- do this to view your data.
The -u option you are using is used for authentication. For example for http-authentication.
In case you want to add data, you have to modify your -d parameter. For example, here i added a user:
-d "{\"name\":\"John\",\"age\":\"31\",\"test\":\"New York\",\"user\":\"test-user\"}"
Or in the other case you really want the http-authentication-data use:
$_SERVER['PHP_AUTH_USER']
$_SERVER['PHP_AUTH_PW']

Problem parsing the body of a POST request

So what I'm trying to do is: with a link similar to: http://localhost/API-REST/Endpoints/ajoutDeMessage.php?contenu='Hello'&idUser=4. For now, I'm only testing my request with Postman. So I'm putting this URL directly in Postman, and press send.
When I'm doing a request without a body, it works fine.
So, I need to send a string and an id through the URL, and with a function, I'm inserting these data in my database.
With the php://input, I expect to have the variables contenu and idUser in the body for a SQL request.
What I want to do next is a React app which will communicate with the API (but that's not related for now).
So here is my code:
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
require_once('../Configuration/database.php');
require_once('../Users/messages.php');
$database = new Database();
$db = $database->getConnection();
$json = json_decode(file_get_contents("php://input"),true);
var_dump($json);
if(!empty($json->contenu) && !empty($json->idUser)){
$contenu = strip_tags($json->contenu);
$idUser = strip_tags($json->idUser);
$message = new Messages($db);
if ($message->addMessage($contenu,$idUser)){
http_response_code(201);
$response['message'] = 'GOOD ENTRY';
}else{
http_response_code(400);
$response['message'] = 'BAD ENTRY';
}
}else{
http_response_code(400);
$response['message'] = 'INCOMPREHENSIBLE DATA';
}
echo json_encode($response);
} else {
http_response_code(405);
$response['error_code'] = 405;
$response['message'] = 'BAD REQUEST TYPE';
echo json_encode($response);
}
There is no post body
i'm putting this url directly in postman, and press send.
I don't use postman myself, but doing this will generate a post request with no data it's the equivalent of:
curl -X POST http://example.com
That's not passing a post body at all. The intent is more like:
curl http://example.com
-H 'Content-Type: application/json'
-d '{"contenu":"Hello","idUser":4}'
This is why file_get_contents("php://input") doesn't return anything.
Note that html form data is available via $_POST - but only for urlencoded POST bodies (which I understand not to be the intent of the question).
Where is the data?
i'm putting this url directly in postman, and press send.
Returning to this quote, the only place for the data is in the url - that is not the normal way to pass data with a post request.
Url arguments are available via $_GET, with the url in the question this code:
<?php
var_dump($_GET);
will output:
array(2) {
["contenu"]=>
string(7) "'Hello'"
["idUser"]=>
string(1) "4"
}
A detail, but note the string includes the single quotes which are in the url (that are probably not desired).
What's the right way to do this?
With a request being made like this:
curl http://example.com
-H 'Content-Type: application/json'
-d '{"contenu":"Hello","idUser":4}'
That data can be accessed like so:
<?php
$body = file_get_contents('php://input');
$data = json_decode($body, true);
$jsonError = json_last_error();
if ($jsonError) {
print_r(['input' => $body, 'error' => json_last_error_msg()]);
exit;
}
echo $data['contenu']; // Hello
echo $data['idUser']; // 4
...
This is very similar to the code in the question, the error appears to primarily be how the request is being made rather than the php logic.

JSON: Update base64 string using url JSON

I'm new to JSON Code. I want to learn about the update function. Currently, I successfully can update data to the database. Below is the code.
<?php
require_once "../config/configPDO.php";
$photo_after = 'kk haha';
$report_id = 1;
$url = "http://172.20.0.45/TGWebService/TGWebService.asmx/ot_maintainReport?taskname=&reportStatus=&photoBefore=&photoAfter=". urlencode($photo_after) . "&reportID=$report_id";
$data = file_get_contents($url);
$json = json_decode($data);
$query = $json->otReportList;
if($query){
echo "Data Save!";
}else{
echo "Error!! Not Saved";
}
?>
the problem is, if the value of $photo_after is base64 string, which is too large string, it will give the error:
1) PHP Warning: file_get_contents.....
2) PHP Notice: Trying to get property 'otReportList' of non-object in C:
BUT
when I change the code to this,
<?php
require_once "../config/configPDO.php";
$photo_after = 'mama kk';
$report_id = 1;
$sql = "UPDATE ot_report SET photo_after ='$photo_after', time_photo_after = GETDATE(), ot_end = '20:30:00' WHERE report_id = '$report_id'";
$query = $conn->prepare($sql);
$query->execute();
if($query){
echo "Data Save!";
}else{
echo "Error!! Not Saved";
}
?>
The data will updated including when the value of $photo_after is in base 64 string.
Can I know what is the problem? Any solution to allow the base64 string update thru json link?
Thanks
// ...
// It's likely that the following line failed
$data = file_get_contents($url);
// ...
If the length of $url is more than 2048 bytes, that could cause file_get_contents($url) to fail. See What is the maximum length of a URL in different browsers?.
Consequent to such failure, you end up with a value of $json which is not an object. Ultimately, the property otReportList would not exist in $json hence the error: ...trying to get property 'otReportList' of non-object in C....
To surmount the URL length limitation, it would be best to embed the value of $photo_after in the request body. As requests made with GET method should not have a body, using POST method would be appropriate.
Below is a conceptual adjustment of your code to send the data with a POST method:
<?php
require_once "../config/configPDO.php";
# You must adapt backend behind this URL to be able to service the
# POST request
$url = "http://172.20.0.45/TGWebService/TGWebService.asmx/ot_maintainReport";
$report_id = 1;
$photo_after = 'very-long-base64-encoding-of-an-image';
$request_content = <<<CONTENT
{
"taskname": $taskname,
"report_id": $report_id,
"photoBefore": $photoBefore,
"photo_after": $photo_after,
"reportStatus": $reportStatus
}
CONTENT;
$request_content_length = strlen($request_content);
# Depending on your server configuration, you may need to set
# $request_headers as an associative array instead of a string.
$request_headers = <<<HEADERS
Content-type: application/json
Content-Length: $request_content_length
HEADERS;
$request_options = array(
'http' => array(
'method' => "POST",
'header' => $request_headers,
'content' => $request_content
)
);
$request_context = stream_context_create($request_options);
$data = file_get_contents($url, false, $request_context);
# The request may fail for whatever reason, you should handle that case.
if (!$data) {
throw new Exception('Request failed, data is invalid');
}
$json = json_decode($data);
$query = $json->otReportList;
if ($query) {
echo "Data Save!";
} else {
echo "Error!! Not Saved";
}
?>
sending a long GET URL is not a good practice. You need to use POST method with cURL. And your webservice should receive the data using post method.
Here's example sending post using PHP:
//
// A very simple PHP example that sends a HTTP POST to a remote site
//
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://www.example.com/tester.phtml");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"postvar1=value1&postvar2=value2&postvar3=value3");
// In real life you should use something like:
// curl_setopt($ch, CURLOPT_POSTFIELDS,
// http_build_query(array('postvar1' => 'value1')));
// Receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
curl_close ($ch);
// Further processing ...
if ($server_output == "OK") { ... } else { ... }
Sample code from: PHP + curl, HTTP POST sample code?
And all output from the webservice will put in the curl_exec() method and from there you can decode the replied json string.

How to get VKontakte photo, name, id using PHP with JSON

I have the issuses with VK access_token. I added to &access_token= a Secure key of the project, but VKontakte still says that User authorization failed: invalid access_token (4)..
How I can fix it?
$url = 'personasvk';
function get_vk($username) {
$get = get_data('https://api.vk.com/method/users.get?user_id='.$username.'&v=5.85&access_token=SECURE_KEY_OF_PROJECT');
$result = json_decode($get, true);
if (empty($result['response'][0]['gid']) || empty($result['response'][0]['screen_name'])) {
return false;
} else {
return $result;
}
}
$vk_data = get_vk($url);
$title = $vk_data['response'][0]['screen_name'];
$link_id = $vk_data['response'][0]['gid'];
$image = $vk_data['response'][0]['photo'];
echo $title;
Try adding it in the body of your POST request.
I am not familiar with PHP, but this curl gives me all the necessary information.
curl -X POST \
-d 'v=5.85' \
-d 'access_token=SECURE_KEY_OF_PROJECT' \
-d 'user_id=700' \
https://api.vk.com/method/users.get

Facebook Messenger API - Can't verify webhook URL (PHP)

I'm trying to set up a fb messenger chatbot but don't seem to be able to get the webhook callback url verified. Every time I try to verify it I get this error message - The URL couldn't be validated. Response does not match challenge, expected value = '1596214014', received=''
Here's the screenshot:
Screenshot
Here's the php I'm using -
<?php
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'token_my_token') {
echo $challenge;
}
I've also tried
echo $_GET['hub_challenge'];
and just
echo file_get_contents('php://input');
All of these result in the same error message as above. Basically, as far as I can tell facebook isn't sending a GET request to my server or if it is it doesn't include any data. Can anyone tell if I am doing something wrong or if there is a setting I need to change to ensure facebook is sending the data correctly?
Edit - When checking the access logs this is what I find, which looks like facebook isn't sending any data in the get request.

Thanks
just try my code and it's gonna work.
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'Your's app token') {
echo $challenge;
}
//Token of app
$row = "Token";
$input = json_decode(file_get_contents('php://input'), true);
//Receive user
$sender = $input['entry'][0]['messaging'][0]['sender']['id'];
//User's message
$message = $input['entry'][0]['messaging'][0]['message']['text'];
//Where the bot will send message
$url = 'https://graph.facebook.com/v2.6/me/messages?access_token='.$row;
$ch = curl_init($url);
//Answer to the message adds 1
if($message)
{
$jsonData = '{
"recipient":{
"id":"'.$sender.'"
},
"message":{
"text":"'.$message. ' 1' .'"
}
}';
};
$json_enc = $jsonData;
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_enc);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
if(!empty($input['entry'][0]['messaging'][0]['message'])){
$result = curl_exec($ch);
}
you have to return Challenges so Facebook can verify its correct Url and Token Match
<?php
$challenge = $_REQUEST['hub_challenge'];
$verify_token = $_REQUEST['hub_verify_token'];
if ($verify_token === 'token_my_token') {
echo $challenge;
}
Facebook Docs Link ( In Node.js ) You can see challenge return after verifying the token
https://developers.facebook.com/docs/messenger-platform/getting-started/webhook-setup
Could you try my API? https://github.com/Fritak/messenger-platform
If you set it like in example, it should work:
// This is just an example, this method of getting request is not safe!
$stream = file_get_contents("php://input");
$request = empty($stream)? $_REQUEST : $stream;
$bot = new \fritak\MessengerPlatform(
['accessToken' => 'token_for_app',
'webhookToken' => 'my_secret_token',
'facebookApiUrl' => 'https://graph.facebook.com/v2.6/me/' //2.6 is minimum
], $request);
if($bot->checkSubscribe())
{
print $bot->request->getChallenge();
exit;
}
If not, problem is somewhere between Facebook and script, not in PHP itself. Go check apache settings etc.
Well issue might be on facebook side, they had some issues over past few days...
Have only this code in your php file: (fbmessenger.php)
<?php
// header('HTTP/1.1 200 OK');
/* GET ALL VARIABLES GET & POST */
foreach ($_REQUEST AS $key => $value){
$message .= "$key => $value ($_SERVER[REQUEST_METHOD])\n";
}
$input = file_get_contents("php://input");
$array = print_r(json_decode($input, true), true);
file_put_contents('fbmessenger.txt', $message.$array."\nREQUEST_METHOD: $_SERVER[REQUEST_METHOD]\n----- Request Date: ".date("d.m.Y H:i:s")." IP: $_SERVER[REMOTE_ADDR] -----\n\n", FILE_APPEND);
echo $_REQUEST['hub_challenge'];
You will have requests saved in a file called "fbmessenger.txt" in the same directory.
Note that for some strange reason you may need to submit few times to
get it approved & saved! (I had to hit "save" 8-9 times before fb
approved link)
Make sure you use https (SSL) connection and once your connection is done, verify your token with "hub_verify_token" to make sure request is coming from fb.

Importing quotes into vtiger crm with web services

I need to import quotes into vtiger.
I find out it can be be done using vtiger web services API
I find out the reference manual:
https://wiki.vtiger.com/archives/index.php/vtiger510:Webservice_reference_manual
But i can't find any example PHP script, neither what data fields I need to pass to webservice.php.
Please help, I need some guidance.
I have done something like this, I have a quick and (rather) dirty but working solution:
<?php
function createOffer($account_id,$subject,$offerlanguage, $totalamount,$date_submission,$date_decision,$date_start,$assigned_user_id,$quotestage,$winningchance,$description,$productarray){
global $adb;
$endpointUrl = "[your URL]/webservice.php";
$userName="admin";
$userAccessKey = '[your accesskey]';
$httpc = new HTTP_CLIENT();
//getchallenge request must be a GET request.
$httpc->GET($endpointUrl."?operation=getchallenge&username=".$userName);
$response = $httpc->currentResponse();
//decode the json encode response from the server.
$jsonResponse = Zend_JSON::decode($response['body']);
//check for whether the requested operation was successful or not.
if($jsonResponse['success']==false)
//handle the failure case.
die('getchallenge failed:'.$jsonResponse['error']['errorMsg']);
//operation was successful get the token from the reponse.
$challengeToken = $jsonResponse['result']['token'];
//create md5 string concatenating user accesskey from my preference page
//and the challenge token obtained from get challenge result.
$generatedKey = md5($challengeToken.$userAccessKey);
//getchallenge request must be a GET request.
$httpc->post("$endpointUrl",
array('operation'=>'login', 'username'=>$userName, 'accessKey'=>$generatedKey), true);
$response = $httpc->currentResponse();
//decode the json encode response from the server.
$jsonResponse = Zend_JSON::decode($response['body']);
//operation was successful get the token from the reponse.
if($jsonResponse['success']==false)
//handle the failure case.
die('login failed:'.$jsonResponse['error']['errorMsg']);
//login successful extract sessionId and userId from LoginResult to it can used for further calls.
$sessionId = $jsonResponse['result']['sessionName'];
$userId = $jsonResponse['result']['userId'];
$currency_id=1;
$params = array('description'=>$description,'subject'=>$subject,'quotestage'=>$quotestage,'assigned_user_id'=>'2x'.$assigned_user_id,'account_id'=>'3x'.$account_id,'cf_682'=>$offerlanguage,'currency_id'=>'21x'.$currency_id,'taxtype'=>'group','cf_683'=>$date_submission,'cf_684'=>$date_decision,'cf_685'=>$date_start,'cf_766'=>$winningchance);
$urlArgs = "?&total=".$totalamount;
//encode the object in JSON format to communicate with the server.
$objectJson = Zend_JSON::encode($params);
//name of the module for which the entry has to be created.
$moduleName = 'Quotes';
//sessionId is obtained from loginResult.
$params = array("sessionName"=>$sessionId, "operation"=>'create', "element"=>$objectJson, "elementType"=>$moduleName);
//Create must be POST Request.
$httpc->post($endpointUrl.$urlArgs, $params, true);
$response = $httpc->currentResponse();
//decode the json encode response from the server.
$jsonResponse = Zend_JSON::decode($response['body']);
$savedObject = $jsonResponse['result'];
$id = $savedObject['id'];
$id=str_replace("13x", "", $id);
echo $id." offer: ".$subject." created for amount ".$totalamount." for customer: ".$account_id." assigned to: ".$assigned_user_id;
return $id;
}
As you see there are a few custom fields too so you can see how I've handled those.
You can call this function like this:
createOffer($account_id, $subject, $offerlanguage, $totalamount, $date_submission, $date_decision, $date_start, $assigned_user_id, $quotestage, $winningchance, $description, $productarray)
Then you need to add the products too, which I've found the easiest via a separate function as there can be more products per quote...
<?php
function createProducts($productarray,$id) {
$counter = 1;
foreach ($productarray as $prod) {
$query ="insert into vtiger_inventoryproductrel(id, productid, sequence_no, quantity, listprice) values(?,?,?,?,?)";
$qparams = array($id,$prod['prod'],$counter,$prod['pcs'],$prod['price']);
$productadded=$adb->pquery($query,$qparams);
$counter=$counter+1;
}
}
use it like this:
$prodlist = array();
array_push($prodlist,array('prod'=>"prod1",'pcs'=>2,'price'=>1000));
array_push($prodlist,array('prod'=>"prod2",'pcs'=>2,'price'=>100));
createProducts($prodlist,10);
so my logic is like this:
you create the quote with the createOffer function. It returns with the newly created quote's ID
then you build the array of products (I have just the very basic data here) and add that by referencing the quote's ID
Maybe not the most beautiful solution but works.
Maybe you can start like this (according to your reference link).
