有沒有想過，向一個公衆號發送長連接，而後公衆號給你回覆一個短網址？php

其實很簡單：json

<?php
define("TOKEN", "xiao");
//用於回覆用戶消息
function responseMsg(){
    $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
    if (!empty($postStr)){
        $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
        $fromUsername = $postObj->FromUserName;
        $toUsername = $postObj->ToUserName;
        $MsgT = $postObj->MsgType;
        $time = time();
        //若是用戶發的text類型
        if($MsgT=="text"){
            $key = trim($postObj->Content);
            $textTpl = "<xml>
                        <ToUserName><![CDATA[%s]]></ToUserName>
