Im trying to shorten a url using ggole api's.Here is my php code .It gives a blank page when i load
<?php
define('GOOGLE_API_KEY', 'GoogleApiKey');
define('GOOGLE_ENDPOINT', 'https://www.googleapis.com/urlshortener/v1');
function shortenUrl($longUrl)
{
// initialize the cURL connection
$ch = curl_init(
sprintf('%s/url?key=%s', GOOGLE_ENDPOINT, GOOGLE_API_KEY)
);
// tell cURL to return the data rather than outputting it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// create the data to be encoded into JSON
$requestData = array(
'longUrl' => $longUrl
);
// change the request type to POST
curl_setopt($ch, CURLOPT_POST, true);
// set the form content type for JSON data
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
// set the post body to encoded JSON data
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($requestData));
// perform the request
$result = curl_exec($ch);
curl_close($ch);
// decode and return the JSON response
return json_decode($result, true);
}
if (isset($_POST['url'])) {
$url = $_POST['url'];
$response = shortenUrl('$url');
echo sprintf(
$response['longUrl'],
$response['id']
);
}
?>
My html file:
<html>
<head>
<title>A BASIC HTML FORM</title>
</head>
<body>
<FORM NAME ="form1" METHOD =" " ACTION = "shortner.php">
<INPUT TYPE = "TEXT" VALUE ="Enter a url to shorten" name="url">
<INPUT TYPE = "Submit" Name = "Submit1" VALUE = "Shorten">
</FORM>
</body>
</html
I think I have found a solution to your problem. Since you are connecting to a URL that uses SSL, you will need to add some extra parameters to your code for CURL. Try the following instead:
<?php
define('GOOGLE_API_KEY', 'GoogleApiKey');
define('GOOGLE_ENDPOINT', 'https://www.googleapis.com/urlshortener/v1');
function shortenUrl($longUrl)
{
// initialize the cURL connection
$ch = curl_init(
sprintf('%s/url?key=%s', GOOGLE_ENDPOINT, GOOGLE_API_KEY)
);
// tell cURL to return the data rather than outputting it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// create the data to be encoded into JSON
$requestData = array(
'longUrl' => $longUrl
);
// change the request type to POST
curl_setopt($ch, CURLOPT_POST, true);
// set the form content type for JSON data
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
// set the post body to encoded JSON data
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($requestData));
// extra parameters for working with SSL URL's; eypeon (stackoverflow)
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
// perform the request
$result = curl_exec($ch);
curl_close($ch);
// decode and return the JSON response
return json_decode($result, true);
}
if (isset($_POST['url'])) {
$url = $_POST['url'];
$response = shortenUrl('$url');
echo sprintf(
$response['longUrl'],
$response['id']
);
}
?>
I think it's coming form your html. You didn't put the form methode, so it send data by get.
And you show something only if you have post.
Try to do in the form method="post"
Edit
Bobby the main problem is that you don't have one problem but several in this code.
First if you don't do
<FORM NAME="form1" METHOD="POST" ACTION="shortner.php">
the if (isset($_POST['url'])) will never return true, because the variable send by the form will be GET (or do a if (isset($_GET['url']))).
Secondly you call the function with { $response = shortenUrl('$url'); }. Here you're not sending the url value but the string '$url'. So your variable $longUrl is always '$url'.
Thirdly you don't use sprintf like you should.
echo sprintf(
$response['longUrl'],
$response['id']
);
Sprintf need to take a string format:
echo sprintf("%s %s" // for example
$response['longUrl'],
$response['id']
);
But do you know that you can do directly
echo $response['longUrl'] . ' ' . $response['id'];
You can concatenate string directly with . in php
curl_exec() returns boolean false if something didn't go right with the request. You're not testing for that and assuming it worked. Change your code to:
$result = curl_exec($ch);
if ($result === FALSE) {
die("Curl error: " . curl_error($ch);
}
As well, you need to specify CURLOPT_RETURNTRANSFER - by default curl will write anything it receives to the PHP output. With this option set, it'll return the transfer to your $result variable, instead of writing it out.
You need to set CURLOPT_RETURNTRANSFER option in your code
function shortenUrl($longUrl)
{
// initialize the cURL connection
$ch = curl_init(
sprintf('%s/url?key=%s', GOOGLE_ENDPOINT, GOOGLE_API_KEY)
);
// tell cURL to return the data rather than outputting it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// create the data to be encoded into JSON
$requestData = array(
'longUrl' => $longUrl
);
// change the request type to POST
curl_setopt($ch, CURLOPT_POST, true);
// set the form content type for JSON data
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
// set the post body to encoded JSON data
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($requestData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
// perform the request
$result = curl_exec($ch);
curl_close($ch);
// decode and return the JSON response
return json_decode($result, true);
}
if (isset($_POST['url'])) {
$url = $_POST['url'];
$response = shortenUrl('$url');
echo sprintf(
$response['longUrl'],
$response['id']
);
}
// Create cURL
$apiURL = https://www.googleapis.com/urlshortener/v1/url?key=gfskdgsd
$ch = curl_init();
// If we're shortening a URL...
if($shorten) {
curl_setopt($ch,CURLOPT_URL,$apiURL);
curl_setopt($ch,CURLOPT_POST,1);
curl_setopt($ch,CURLOPT_POSTFIELDS,json_encode(array("longUrl"=>$url)));
curl_setopt($ch,CURLOPT_HTTPHEADER,array("Content-Type: application/json"));
}
else {
curl_setopt($ch,CURLOPT_URL,$this->apiURL.'&shortUrl='.$url);
}
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
// Execute the post
$result = curl_exec($ch);
// Close the connection
curl_close($ch);
// Return the result
return json_decode($result,true);

I want to send data from server 1 to server 2, first I select necessary data from the database, but how to send data with curl? I understand that I cannot send $result parameter just like in my code, but how should I do this?
My Code server 1:
public function setDivisions(){
$result = $this->conn->query("SELECT *FROM data_divisions");
$ch = curl_init('https://example.com/api.php?siteid='.$this->site_key.'');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $result);
curl_setopt($ch, CURLOPT_POST, 1);
$response = curl_exec($ch);
print_r($response);
}
Code on server 2:
$array = $_POST['result'];
//loop throw array and insert data into database
you can use it that way.
$ch = curl_init('https://upxxx.cod3fus1ontm.com/curl/json');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode((object)["records" => json_encode($result)]));
$response = curl_exec($ch);
var_dump($response);
on receipt, like this!
$json = file_get_contents("php://input");
$content = json_decode($json, true);
$records = json_decode($content['records'], true);
foreach($records as $record) {
echo $record['id'] . " - " . $record['text'] . "<br/>";
}
remember, that as you did to encode, you will have to do to decode
Come on, php://input returns all raw data after the request's HTTP headers, regardless of content type.
When we do this with file_get_contents (which reads the contents of a file and puts it into a variable of type string), we can read the content that was sent by curl.
Reviewing the code, you can optimize as follows, when sending to the server you placed, I suggested:
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode((object)["records" => json_encode($result)]));
you can replace it with:
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($result));
it's much simpler, but it's very important to put the query result inside a json_encode
finally, you can access the entire body of the message, through file_get_contents ("php://input") and put it inside a variable, which is nothing more than a JSON of the your query.
for you to understand how the parameters were passed, it is interesting to do the following:
$json = file_get_contents("php: // input");
var_dump($json); <- Here you see the thing as it is.
$records = json_decode($json, true); <- Here you generate an object with the content of json
var_dump($records);
With that, I think that solves the situation.
on server 1
$result = "result=".base64_encode($result)
curl_setopt($ch, CURLOPT_POSTFIELDS, $result);
...
on server 2
$array = base64_decode($_POST['result']);
Trying to add some kind of value to each data point so I can send the response (numbers only) to an existing table . I've been searching online and no CURL API response seems to be this simple so I can find an answer. (sorry new to this, don't know the "lingo")
This is the response I've been able to echo on screen.
"{"price": 2049.27, "change_point": -5.76, "change_percentage": -0.28, "total_vol": "1.27M"}"
rest of php below
<html>
<?php
$url = 'https://realstonks.p.rapidapi.com/';
$collection_name = $_REQUEST["stock_name"];
$request_url = $url . '/' . $collection_name;
$curl = curl_init($request_url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, [
'X-RapidAPI-Host: www.xyz.com',
'X-RapidAPI-Key: xxxxxxxxxxxxxxxxxxx',
'Content-Type: application/json']);
$response = curl_exec($curl);
curl_close($curl);
//Uncomment bellow to show data on screen
echo $response . PHP_EOL;
enter code here
//var_dump(json_decode($json));
//var_dump(json_decode($json, true));
// Initiate curl
$ch = curl_init();
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);

I'm not much into PHP but here to here. If I'm not mistaken it, I think you want to store $response in <td> element. This resource can help https://www.daniweb.com/programming/web-development/threads/428730/how-to-display-php-variable-in-html
I am developing a PHP script that:
Gets 10 rows from DB (works well)
Sends addresses from these rows to Map API
Obtains data
Save results in DB (works well)
I don't know how to obtain the final response of curl_exec. curl_exec
in $response = call('GET', $query);
- even when hasn't completed returns something in response.
These my loop that is waiting for the response of the call function. But it doesn't work json_decode($stringJSON) is invoked earlier than it is obtained the final response
$requestHandled = false;
$response = "";
$response = call('GET', $query);
while(!$requestHandled) {
if(strlen($response) > 5){
$response = mb_convert_encoding($response, "UTF-8");
$stringJSON = get_magic_quotes_gpc() ? stripslashes($response) : $response;
echo $stringJSON;
$jsonObject = "+";
echo $jsonObject;
$jsonObject = json_decode($stringJSON);
echo $jsonObject;
$requestHandled = true;
}
}
This is my curl call function
function call($method, $url, $data = false) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($ch, CURLOPT_URL, $url);
if ($data) {
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Content-Length: ' . strlen($data);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
return curl_exec($ch);
Please help. Has spent a half of the day solving it
So the result of the var_dump( $response ) is an empty string?
In that case, it simply means the response from the server is empty, because I just tested your function call() and it seems to work just fine. In other words, make sure the URL (with the method GET) you are trying to call actually returns data to begin with.
I wouldn't be surprised if you simply have a typographical error somewhere in the URL.
Also, for debugging purposes, temporarily replace
return curl_exec($ch);
with
$result = curl_exec($ch);
var_dump(curl_getinfo($ch));
return $result;
and investigate the info in the var_dump() result, to make sure the response code is 200 (or any other that indicates success) and not in the 4xx or 5xx ranges (respectively indicating either a client or server error), for instance.
See curl_getinfo() for more information about what useful information will be returned about your last curl transfer.
To address OPs comment(s):
Please try this complete script (nothing else: no while loop, no stripslashes(), no json_decode(), etc):
<?php
function call($method, $url, $data = false) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method);
curl_setopt($ch, CURLOPT_URL, $url);
if ($data) {
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$headers = array();
$headers[] = 'Content-Type: application/json';
$headers[] = 'Content-Length: ' . strlen($data);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
var_dump(curl_getinfo($ch)); // check this result and make sure the response code is 200
return $result;
}
$query = 'fill in the correct URL! (with http(s)://)';
$response = call('GET', $query);
var_dump( $response ); // check this result and see if it's an empty string
die;
If the var_dump( $response ); returns an empty string, it means your script works fine but the URL you are calling simply returned an empty response.
If $response is not empty and actually contains JSON data, replace
var_dump( $response );
with
$stringJSON = mb_convert_encoding( $response, "UTF-8" );
echo $stringJSON; // make sure this contains valid JSON data
// stripslashes() should not be needed
var_dump( json_decode( $stringJSON ) ); // if JSON data was valid, you should get a valid PHP data structure
I am creating a web service. I have tried to write an URL but its throwing error. I am not getting where I am going wrong. I want to pass these variable values in url and depending on this i want to call the web service
<?php
if($_POST["occupation"] == '1'){
$occupation = 'Salaried';
}
else{
$occupation = 'Self+Employed';
}
$url = 'http://www.aaa.com/ajaxv2/getCompareResults.html?interestRateType='.$_POST["interestRateType"]'.&occupation='.$_POST["occupation"].'&offeringTypeId='.$_POST["offeringID"].'&city='.$_POST["city"].'&loanAmt='.$_POST["loanAmt"].'&age='.$_POST["age"];
echo $url;
// Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
$json = json_decode($result, true);
//print_r($json);
//echo $json['resultList']['interestRateMin'];
$json_array = $json['resultList'];
print_r($json_array);
?>
Try below code. You have syntax error before &occupation
$url = 'http://www.aaa.com/ajaxv2/getCompareResults.html?interestRateType='.$_POST["interestRateType"].'&occupation='.$_POST["occupation"].'&offeringTypeId='.$_POST["offeringID"].'&city='.$_POST["city"].'&loanAmt='.$_POST["loanAmt"].'&age='.$_POST["age"];
Copy this because there is some ' and . error
$url = 'http://www.aaa.com/ajaxv2/getCompareResults.html?
interestRateType='.$_POST["interestRateType"].'&
occupation='.$_POST["occupation"].'&
offeringTypeId='.$_POST["offeringID"].'&
city='.$_POST["city"].'&
loanAmt='.$_POST["loanAmt"].'&
age='.$_POST["age"];
