微信公众平台接口测试帐号申请

https://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=sandbox/login

无需公众帐号、快速申请接口测试号直接体验和测试公众平台所有高级接口

 

请把以下代码保存成php文件,然后在接口配置信息中的URL填写此文件网址

然后文件中的Token值修改成一致即可(Token值自己定义).

 

<?php

/**
 * wechat php test
 */

//define your token
define("TOKEN", "你设置的Token值");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();


class wechatCallbackapiTest
{
	public function valid()
  {
    $echoStr = $_GET["echostr"];


    //valid signature , option
    if($this->checkSignature()){
    	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);
		$tmpStr = implode( $tmpArr );
		$tmpStr = sha1( $tmpStr );
		
		if( $tmpStr == $signature ){
			return true;
		}else{
			return false;
		}
	}
}
