1喉刘、這種自己測(cè)了測(cè)也可以用,直接在你的接口方法內(nèi)寫下如下語(yǔ)句 , 不行的話可以嘗試第二種

echo $_GET['echostr'];die;

2靡菇、將如下代碼粘貼至自己服務(wù)器下面的index.php文件內(nèi)（服務(wù)器地址下面的index.php文件內(nèi)）

/**
  * wechat php test
  */


//你自己設(shè)置的token（自定義的）

define("TOKEN", "wechat");

$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;

        }

    }

}

然后放到服務(wù)器上贺喝，再次提交假抄，多提交兩次
