File_get_contents ('PHP: // input'); with the app / x-www-form-urlencoded;

Question

I read a few questions on the topic here, but could not find the answer I'm looking for. I am making $ .post with jQuery on a PHP5.6 server.

$.post('/', {a:100, b:'test'}, function(data){ }, 'json'); 

Console Encoding

 Content-Type application/x-www-form-urlencoded; charset=UTF-8 

If I try to read POST data with regular $ _POST, PHP5.6 notifies me

 PHP Deprecated: Automatically populating $HTTP_RAW_POST_DATA is deprecated and will be removed in a future version. To avoid this warning set 'always_populate_raw_post_data' to '-1' in php.ini and use the php://input stream instead 

So, I tried the suggestion, added always_populate_raw_post_data = -1 in php.ini and

 json_decode(file_get_contents("php://input")); 

PHP5.6 warns me that it is invalid

 PHP Warning: First parameter must either be an object or the name of an existing class 

So, I threw file_get_contents ("php: // input"), and this is the line.

 a=100&b="test" 

So, I parsed the string and encoded, then decoded

 parse_str(file_get_contents("php://input"), $data); $data = json_decode(json_encode($data)); var_dump($data); 

AND THEN I finally got my $ data as an object, not an array, like a true JSON object.

I resorted to using $ _POST at the moment ... But then I'm curious about updating PHP.

The question is, is there a more direct solution to this, or does using file_get_contents ("php: // input") also mean parsing the syntax coding with the extension?

Edit: so it seems that this does not work on several json's levels. Consider the following:

 {"a":100, "b":{"c":"test"}} 

How sent to Ajax / Post

 {a:100, b:{c:"test"}} 

Performance

 parse_str(file_get_contents("php://input"), $post); var_dump($post); 

Will output

 array(2) { ["a"]=>string(8) "100" ["b"]=>string(16) "{"c":"test"}" } 

Or do (as suggested)

 parse_str(file_get_contents("php://input"), $post); $post= (object)$post; 

Will output

 object(stdClass)#11 (2) { ["a"]=>string(8) "100" ["b"]=>string(16) "{"c":"test"}" 

}

How to convert file_get_contents ("php: // input") to a true object with the same "architecture" without using a recursive function?

Edit2: My error, the proposed work, I got a side in the comments with JSON.stringify that caused the error. Bottom line: it works with json_decode (json_encode ($ post)) or $ post = (object) $ post;

Repeat using jQuery $ .post:

 $.post('/', {a:100, b:{c:'test'}}, function(data){ }, 'json'); parse_str(file_get_contents("php://input"), $data); $data = json_decode(json_encode($data)); 

or

 parse_str(file_get_contents("php://input"), $data); $data= (object)$data; 

No need to use JSON.stringify

Answer 1

My mistake, the proposed work, I got the side tracked in the comments with JSON.stringify , which caused the error. Bottom line: it works with json_decode (json_encode ($ post)) or $ post = (object) $ post; Michael's answer was right, but the parties were tracking me, and I left an error in my code. JSON.stringify is only useful when submitting data from a form, as I replied in a comment.

Answer 2

By receiving sequential / urlencoded POST data in the body of the POST request request, like you, you correctly converted it to an array with parse_str() already.

However, the encoding step and then decoding the JSON to convert it to the object (as opposed to the array) you are looking for is not necessary. Instead, PHP will happily pass an associative array to an object of class stdClass :

 parse_str(file_get_contents("php://input"), $data); // Cast it to an object $data = (object)$data; var_dump($data); 

A bit more information is available in the casting PHP documentation .

To send raw json data, you must stop jQuery from url-encoding:

  data = {"a":"test", "b":{"c":123}}; $.ajax({ type: 'POST', url: '...', data: JSON.stringify(data), // I encode it myself processData: false // please, jQuery, don't bother }); 

On the php side, just read php://input and json_decode it:

 $req = file_get_contents("php://input"); $req = json_decode($req);
