如何对微信公众号基本配置

　　这个是微信公众平台上的配置。

这边的url值要直接点到文件上，不然不会成功.　　

然后后台的设置

 <?php namespace app\weixin\controller;  use think\Controller;  define("TOKEN", "******");//这里要输入你的token值  // $wechatObj = new wechatCallbackapiTest();  // $wechatObj->valid();  class Wx2 extends Controller {          public function index()       {           $echoStr = $_GET["echostr"];              //valid signature , option           if($this->checkSignature()){               ob_clean(); //丢弃缓存中的内容             echo $echoStr;               exit;           }       }          public function responseMsg()       {           //get post data, May be due to the different environments           $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];              //extract post data           if (!empty($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(!empty( $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;           }       }                  private function checkSignature()       {           $signature = $_GET["signature"];           $timestamp = $_GET["timestamp"];           $nonce = $_GET["nonce"];                                  $token = TOKEN;           $tmpArr = array($token, $timestamp, $nonce);           sort($tmpArr,SORT_STRING); 72         $tmpStr = implode( $tmpArr );           $tmpStr = sha1( $tmpStr );                      if( $tmpStr == $signature ){               return true;           }else{               return false;           }       }   }
