PHP version of the micro-credit public platform for the development of verification steps to explain _php example

This article illustrates the verification steps of the development of the PHP version of the micro-trust public platform. Share to everyone for your reference, specific as follows:

Development of micro-credit public platform We are doing a lot more now, here to introduce you to an entry-level micro-letter public platform to verify the basic knowledge, interested and small to see.

The development of micro-letters need to verify that in the official developer center where there is the source code, login to the public account to see the bottom left corner of a developer center click, and then fill in your corresponding Token and URL and then you can verify the success of the words can be developed.

Download micro-letter PHP verification source code in developer Center-developer Documentation-Interface message-Verify message authenticity-pull to the bottom of PHP demo code.

After the download good code is as follows:

<?php/** * WeChat PHP Test * Update time:20141008///define Your token define ("token", "Weixin");
$WECHATOBJ = new Wechatcallbackapitest ();
$WECHATOBJ->valid ();
  Class Wechatcallbackapitest {public function valid () {$echoStr = $_get["Echostr"];
  Valid signature, option if ($this->checksignature ()) {echo $echoStr;
  Exit The Public Function responsemsg () {//get post data, May is due to the different environments $postStr = $GLOBALS ["HT
  Tp_raw_post_data "]; Extract post Data if (!emptyempty ($POSTSTR)) {$POSTOBJ = simplexml_load_string ($postStr, ' simplexmlelement ', LIBXML
    _nocdata);
    $fromUsername = $POSTOBJ->fromusername;
    $toUsername = $POSTOBJ->tousername;
    $keyword = Trim ($postObj->content);
    $time = time (); $TEXTTPL = "<xml> <tousername><! [cdata[%s]]></tousername> <fromusername><! [cdata[%s]]></fromusername> <CreateTime>%s</CreateTime> <msgtype><! [cdata[%S]]></msgtype> <content><!
[cdata[%s]]></content> <FuncFlag>0</FuncFlag> </xml> ";
    if (!emptyempty ($keyword)) {$msgType = "text";
    $CONTENTSTR = "Welcome to WeChat world!";
    $RESULTSTR = sprintf ($TEXTTPL, $fromUsername, $toUsername, $time, $msgType, $CONTENTSTR);
    Echo $resultStr;
    }else{echo "Input something ...";
  }}else {echo "";
  Exit
  The Private Function checksignature () {$signature = $_get["signature"];
  $timestamp = $_get["timestamp"];
$nonce = $_get["nonce"];
$token = token;
  $TMPARR = Array ($token, $timestamp, $nonce);
Sort ($TMPARR, sort_string);
$TMPSTR = implode ($TMPARR);
$TMPSTR = SHA1 ($TMPSTR); if ($tmpStr = = $signature) {return true;}
else{return false;}

 }?>

Where: TOKEN modified for what you want and then in the developer Center to write the same, in the process of validation $wechatObj->valid (); This code can not be removed this is validated, after the success of the validation we will be able to->valid this paragraph $wechatObj (); This annotation is dropped and then used $WECHATOBJ->responsemsg (); For the test.

Note: In the development of the need to put $WECHATOBJ->valid (); To comment out, or in the mobile phone when the test will not show anything.
