Php Wechat can not receive post data solution: 1, open register_globals;2 in php.ini, through the file_get_contents ("php://input") method to obtain post data.

This article operating environment: Windows7 system, PHP7.1 version, Dell G3 computer.

What if php Wechat can't receive post data?

The official PHP API of Wechat cannot obtain postStr data.

In the PHP interface document officially provided by Wechat, there is such a code for dealing with major business.

Public function getIndex () {if (ob_get_contents ()) ob_end_clean (); $postStr = isset ($GLOBALS ["HTTP_RAW_POST_DATA"])? $GLOBALS ["HTTP_RAW_POST_DATA"]:''; / / get data from post if (! empty ($postStr)) {$postObj = simplexml_load_string ($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $this- > postObj = $postObj $this- > fromUserName = $postObj- > FromUserName;// sender $this- > toUserName = $postObj- > ToUserName;// receiver (i.e. this public account) $this- > msgType = trim ($postObj- > MsgType); / / message type $this- > content = trim ($postObj- > Content); $this- > event = trim ($postObj- > Event); $this- > eventKey = trim ($postObj- > EventKey); $this- > dealMsg () } else {$this- > wx- > makeInfo (Input::all ()); $this- > wx- > valid (); / / for non-message push, the default is check} flush ();}

This method uses GLOBALS as a global variable to get the original Post data, but this method also has problems.

To get data through Globals, register_globals in php.ini must be set to ON. In the lower version of php, register data is on by default, but in the higher version, it is closed by default. This is because, after being set to ON, the variable submitted by the form will automatically become a variable, that is, all the variables entered in the address bar will become global variables, which is very insecure.

In addition to $GLOBALS ["HTTP_RAW_POST_DATA"] to get data from post, you can also get data from post through file_get_contents ("php://input") method.
