I try to send text and an image in base64 via the post method.
There is my code:
// $question is just text, and $photo_base64 is a photo (.png) encode in base64 with the javascript function btoa()
function get_iframe($question, $token, $photo_base64){
$url = 'http://www.squareoffs.com/api/v1/squareoffs?auth_token=' . $token;
$data = array('question' => $question);
$data['photo'] = 'data:image/png;base64,' . $photo_base64;
$data = json_encode($data);
$options = array(
'http' => array(
'header' => "Content-Type: application/json\r\n" .
"Accept: application/json\r\n",
'method' => 'POST',
'content' => $data
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
return json_decode($result);
}
But when a taste it (with correct argument), it does not work, the function return false instead of a json file.
Does someone have a hint?
Thank you very much!

Sorry for the messy code in advance. I want to write a code which returns me infos from the official Blizzard API, which I can then print out on my homepage. The code doesn't throw any errors but it doesn't print out something either. For Starters:
I would also prefer using CURL, but my homepage is on a Wordpress Hosting Site and I don't know how to install the CURL Library that way
allow_furl_open is on
$url = "https://eu.battle.net/oauth/token";
$data = array('grant_type' => 'client_credentials');
//HTTP options
$opts = array('http' =>
array(
'method' => 'POST',
'header' => array ('Content-type: multipart/form-data', 'Authorization: Basic ' .
base64_encode("$client_id:$client_pass")),
'content' => json_encode($data)
)
);
//Do request
$context = stream_context_create($opts);
$json = file_get_contents($url, false, $context);
$result = json_decode($json, true);
$accessToken = $json['access_token'];
$tokenURL = "https://us.api.blizzard.com/data/wow/token/?namespace=dynamic-eu";
$opts2 = array('http' =>
array(
'method' => 'POST',
'header' => array('Content-type: multipart/form-data', 'Authorization: Bearer ' . $accessToken),
)
);
$context2 = stream_context_create($opts2);
$json2 = file_get_contents($tokenURL,false,$context2);
$result2 = json_decode($json2, true);
$tokenprice = $result2['price'];
echo "<p>Tokenpreis:" .$tokenprice. "</p>";
I didn't add the $client_id and $client_pass into the code snippet, but this exists obviously. I used this PHP CURL Snippet as template. And this is a short explanation on blizzard's site on how is this supposed to work:
Anyone got any ideas what went wrong? I am really out of ideas here and would love anyone who could help.
Thanks in advance
Based on the curl example from the linked API docs, the content type should be application/x-www-form-urlencoded, and so for the initial request to https://eu.battle.net/oauth/token you should be able to follow the example here.
In your case this will look something like:
$url = 'https://eu.battle.net/oauth/token';
$data = array('grant_type' => 'client_credentials');
$opts = array(
'http' => array(
'method' => 'POST',
'header' => array (
'Content-type: application/x-www-form-urlencoded',
'Authorization: Basic ' . base64_encode("$client_id:$client_pass")
),
'content' => http_build_query($data)
)
);
$context = stream_context_create($opts);
$json = file_get_contents($url, false, $context);
Also, in your code you are storing the raw result from the initial request in $json, then the decoded array in $result, but attempting to get the access_token from the initial request, instead of the decoded array.
I have tried to parse one variable from json decoded variable, i always got null, i even tried to encode to utf-8.
My code:
<?php
$url = 'https://ots-list.org/ajax/getServers';
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => 'POST',
'content' => 'server_name=Return+of+Sayians&game_type=---&client_version=---&server_country=---'
)
);
$context = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }
//var_dump($result);
$string = mb_convert_encoding($result, "UTF-8");
$data = json_decode($string);
print $data->{'players_online'};
?>
I try to get content from https://www.freeformatter.com. I want to get POST data from that site. but my PHP script not working.
$data = array ('htmlString' => '<div class="container"><div class="row"><div class="col-md-8">&encoding=UTF-8', 'indentation' => 'THREE_SPACES');
$data = http_build_query($data);
$context_options = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded\r\n"
. "Content-Length: " . strlen($data) . "\r\n",
'content' => $data
)
);
$context = stream_context_create($context_options);
$result = file_get_contents('https://www.freeformatter.com/html-formatter.html', false, $context);
var_dump($result);
This will not worked. Reason is freeformatter.com is not allowing to give API or POST call. They always return you view-source of html page. This is allow to use from UI but not by API call. I tried with CURL post also. its gives return back view-source of html.
Here is code you can try this works well with different
<?php
$data = array ('htmlString' => '<div class="container"><div class="row"><div class="col-md-8">&encoding=UTF-8', 'indentation' => 'THREE_SPACES');
$data = http_build_query($data);
$context_options = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded\r\n"
. "Content-Length: " . strlen($data['htmlString']) . "\r\n",
'content' => $data
)
);
$context = stream_context_create($context_options);
$result = file_get_contents('https://en99otyaenia.x.pipedream.net', false, $context);
var_dump($result);
Code doesnt have any issue. Issue is with URL.
I am learning and I am trying post data to 4.php and get the result to printed on range.php.. I have already seen the How to post data in PHP using file_get_contents?
<?php
error_reporting(-1);
$postdata = http_build_query(
array('var1' => 'sugumar',
'var2' => 'doh')
);
$opts = array('http'=>array(
'method'=>'post',
'header'=> 'Content-Type: application/x-www-form-urlencoded',
'content'=> $postdata
)
);
$context = stream_context_create($opts);
$result = file_get_contents('http://localhost/php/4.php', false, $context);
print_r($result);//DOESN'T PRINT ANYTHING
?>
4.php
print_r($_REQUST);
$postdata = http_build_query($_POST);
print_r($postdata);
I want to know why it's not printing anything... please help me..
I have updated your code using code from the PHP manual and changes like adding PHP tags to 4.php and fixing typo in $_REQUEST.
Here is the updated code, which seems to be working for me:
<?php
$data = array ('foo' => 'bar', 'bar' => 'baz');
$data = http_build_query($data);
$context_options = array (
'http' => array (
'method' => 'POST',
'header'=> "Content-type: application/x-www-form-urlencoded\r\n"
. "Content-Length: " . strlen($data) . "\r\n",
'content' => $data
)
);
$context = stream_context_create($context_options);
$result = file_get_contents('http://localhost/php/4.php', false, $context);
var_dump($result);//prints something :)
?>
4.php
<?php
print_r($_REQUEST);
$postdata = http_build_query($_POST);
print_r($postdata);
$key = 'fd2fdfsdfsdfdsf';
$secret = 'fdsfdsfdsfdsfdsfsdf';
$basic_credentials = base64_encode($key.':'.$secret);
$opts = array('http' =>
array(
'method' => 'POST',
'header' => 'Authorization: Basic '.$basic_credentials."\r\n".
"Content-type: application/x-www-form-urlencoded;charset=UTF-8\r\n",
'content' => 'grant_type=client_credentials'
)
);
$context = stream_context_create($opts);
$pre_token = file_get_contents('https://api.twitter.com/oauth2/token', false, $context);
$token = json_decode($pre_token, true);
if (isset($token["token_type"]) && $token["token_type"] == "bearer")
{
$opts = array('http' =>
array(
'method' => 'GET',
'header' => 'Authorization: Bearer '.$token["access_token"]
)
);
$context = stream_context_create($opts);
$data = file_get_contents('https://api.twitter.com/1.1/search/users.json?q=twitter', false, $context);
var_dump($data); die();
The code above returns false. I have no idea why. When I change the url into:
https://api.twitter.com/1.1/statuses/user_timeline.json?count=200&user_id=43243243
It works perfectly and returns the whole JSON.
Why is that so? I can't get it to work with any other API methods other than this one. The key and secret are the same in each situation. Nothing should be changed.
