I'm trying validate url for comment form.
Then I thought ”Safe Browsing Lookup API” looked good.
However, the following code only returns an empty array in $result.
What can I do to improve this code?
code:
<?php
$api_key = 'xxx';
$url = 'https://safebrowsing.googleapis.com/v4/threatMatches:find?key=' . $api_key;
$data = [
"client"=>[
"clientId" => "yourcompanyname",
"clientVersion" => "1.5.2"
],
"threatInfo"=>[
"threatTypes" =>["MALWARE", "SOCIAL_ENGINEERING"],
"platformTypes" =>["WINDOWS"],
"threatEntryTypes"=>["URL"],
"threatEntries" =>[
["url"=>"http://goooogleadsence.biz/"],
["url"=>"http://www.urltocheck2.org/"],
["url"=>"http://activefile.ucoz.com/"]
]
]
];
$data_json = json_encode($data);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
$result = curl_exec($ch);
var_dump($result); // -> string(3) "{}"
curl_close($ch);
I have created a simple Rest webservice with Codeigniter.
When i send post data with Curl from another application and display $_POST is empty.
Simple PHP client:
$url = 'http://localhost/ci-access/api_v1/register_events';
$data = array(
'name' => 'tester'
);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
$output = curl_exec($ch);
curl_close($ch);
Codeigniter webservice:
public function register_events() {
die(var_dump($_POST));
}
Is there an option to set in Codeigniter ?
How can i read posted data ?
try pass php curl_setopt($ch, CURLOPT_POST, true); option first or remove it.
When I'm posting json data to API using curl - I'm not getting any output. I would like to send email invitation to recipient.
$url_send ="http://api.address.com/SendInvitation?";
$str_data = json_encode($data);
function sendPostData ($url, $post) {
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($post));
return curl_exec($ch);
}
And here is JSON $str_data
[
{
"authorizedKey" : "abbad35c5c01-xxxx-xxx",
"senderEmail" : "myemail#yahoo.com",
"recipientEmail" : "jaketalledo86#yahoo.com",
"comment" : "Invitation",
"forceDebitCard" : "false"
}
]
And calling function:
$response = sendPostData($url_send, $str_data);
This is the API: https://api.payquicker.com/Help/Api/POST-api-SendInvitation
Try adding curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
And changing http_build_query($post) to $post
The implementation:
<?php
$data = array(
"authorizedKey" => "abbad35c5c01-xxxx-xxx",
"senderEmail" => "myemail#yahoo.com",
"recipientEmail" => "jaketalledo86#yahoo.com",
"comment" => "Invitation",
"forceDebitCard" => "false"
);
$url_send ="http://api.payquicker.com/api/SendInvitation?authorizedKey=xxxxx";
$str_data = json_encode($data);
function sendPostData($url, $post){
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS,$post);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
$result = curl_exec($ch);
curl_close($ch); // Seems like good practice
return $result;
}
echo " " . sendPostData($url_send, $str_data);
?>
The response I get is:
{"success":false,"errorMessage":"Object reference not set to an instance of an object.","status":"N/A"}
But maybe it will work with valid data....
Edit:
For posting xml,
it's the same as on their site, except in a string:
$xml = '
<SendInvitationRequest xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://schemas.datacontract.org/2004/07/PQApi.Models">
<authorizedKey>80c587b9-caa9-4e56-8750-a34b17dba0a2</authorizedKey>
<comment>sample string 4</comment>
<forceDebitCard>true</forceDebitCard>
<recipientEmail>sample string 3</recipientEmail>
<senderEmail>sample string 2</senderEmail>
</SendInvitationRequest>';
Then:
sendPostData($url_send, $xml)
You have to add header:
$headers= array('Accept: application/json','Content-Type: application/json');
And:
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
Otherwise ...
HTTP Status 415 - Unsupported Media Type
... may happen.
You don't need to add headers as you already do json_encode.
just print_r (curl_getinfo($ch)); and see the content type info in it.
My PHP code (free.php) on http://techmentry.com/free.php is
<?php
{
//Variables to POST
$access_token = "b34480a685e7d638d9ee3e53cXXXXX";
$message = "hi";
$send_to = "existing_contacts";
//Initialize CURL data to send via POST to the API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://freesmsgateway.com/api_send");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,
array('access_token' => $access_token,
'message' => urlencode('hi'),
'send_to' => $send_to,)
);
//Execute CURL command and return into variable $result
$result = curl_exec($ch);
//Do stuff
echo "$result";
}
?>
I am getting this error: THE MESSAGE WAS BLANK
This error means: "The message field was blank or was not properly URL encoded" (as told by my SMS gateway). But as you can see that my message field isn't blank.
I believe you can't send an array to CURLOPT_POSTFIELDS, you would need to replace the line with the following
curl_setopt($ch, CURLOPT_POSTFIELDS, "access_token=".$accesstoken."&message=".urlencode('hi')."&send_to=".$send_to);
I hope this solves it
Use http_build_query():
<?php
{
$postdata = array();
//Variables to POST
$postdata['access_token'] = "b34480a685e7d638d9ee3e53cXXXXX";
$postdata['message'] = "hi";
$postdata['send_to'] = "existing_contacts";
//Initialize CURL data to send via POST to the API
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://freesmsgateway.com/api_send");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postdata) );
//Execute CURL command and return into variable $result
$result = curl_exec($ch);
//Do stuff
echo "$result";
}
?>
How do you pass $_POST values to a page using cURL?
Should work fine.
$data = array('name' => 'Ross', 'php_master' => true);
// You can POST a file by prefixing with an # (for <input type="file"> fields)
$data['file'] = '#/home/user/world.jpg';
$handle = curl_init($url);
curl_setopt($handle, CURLOPT_POST, true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
curl_exec($handle);
curl_close($handle)
We have two options here, CURLOPT_POST which turns HTTP POST on, and CURLOPT_POSTFIELDS which contains an array of our post data to submit. This can be used to submit data to POST <form>s.
It is important to note that curl_setopt($handle, CURLOPT_POSTFIELDS, $data); takes the $data in two formats, and that this determines how the post data will be encoded.
$data as an array(): The data will be sent as multipart/form-data which is not always accepted by the server.
$data = array('name' => 'Ross', 'php_master' => true);
curl_setopt($handle, CURLOPT_POSTFIELDS, $data);
$data as url encoded string: The data will be sent as application/x-www-form-urlencoded, which is the default encoding for submitted html form data.
$data = array('name' => 'Ross', 'php_master' => true);
curl_setopt($handle, CURLOPT_POSTFIELDS, http_build_query($data));
I hope this will help others save their time.
See:
curl_init
curl_setopt
Ross has the right idea for POSTing the usual parameter/value format to a url.
I recently ran into a situation where I needed to POST some XML as Content-Type "text/xml" without any parameter pairs so here's how you do that:
$xml = '<?xml version="1.0"?><stuff><child>foo</child><child>bar</child></stuff>';
$httpRequest = curl_init();
curl_setopt($httpRequest, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($httpRequest, CURLOPT_HTTPHEADER, array("Content-Type: text/xml"));
curl_setopt($httpRequest, CURLOPT_POST, 1);
curl_setopt($httpRequest, CURLOPT_HEADER, 1);
curl_setopt($httpRequest, CURLOPT_URL, $url);
curl_setopt($httpRequest, CURLOPT_POSTFIELDS, $xml);
$returnHeader = curl_exec($httpRequest);
curl_close($httpRequest);
In my case, I needed to parse some values out of the HTTP response header so you may not necessarily need to set CURLOPT_RETURNTRANSFER or CURLOPT_HEADER.
Another simple PHP example of using cURL:
<?php
$ch = curl_init(); // Initiate cURL
$url = "http://www.somesite.com/curl_example.php"; // Where you want to post data
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, true); // Tell cURL you want to post something
curl_setopt($ch, CURLOPT_POSTFIELDS, "var1=value1&var2=value2&var_n=value_n"); // Define what you want to post
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // Return the output in string format
$output = curl_exec ($ch); // Execute
curl_close ($ch); // Close cURL handle
var_dump($output); // Show output
?>
Instead of using curl_setopt you can use curl_setopt_array.
http://php.net/manual/en/function.curl-setopt-array.php
$query_string = "";
if ($_POST) {
$kv = array();
foreach ($_POST as $key => $value) {
$kv[] = stripslashes($key) . "=" . stripslashes($value);
}
$query_string = join("&", $kv);
}
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
$url = 'https://www.abcd.com/servlet/';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($kv));
curl_setopt($ch, CURLOPT_POSTFIELDS, $query_string);
curl_setopt($ch, CURLOPT_HEADER, FALSE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, FALSE);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$result = curl_exec($ch);
curl_close($ch);
$url='Your url'; // Specify your url
$data= array('parameterkey1'=>value,'parameterkey2'=>value); // Add parameters in key value
$ch = curl_init(); // Initialize cURL
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch);
<?php
function executeCurl($arrOptions) {
$mixCH = curl_init();
foreach ($arrOptions as $strCurlOpt => $mixCurlOptValue) {
curl_setopt($mixCH, $strCurlOpt, $mixCurlOptValue);
}
$mixResponse = curl_exec($mixCH);
curl_close($mixCH);
return $mixResponse;
}

$arrPostData = array(

'key3' => array(

// You can set your post data
