有没有想过，向一个公众号发送长链接，然后公众号给你回复一个短网址？
其实很简单：
<?php define("TOKEN", "xiao"); //用于回复用户消息 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; $time = time(); //如果用户发的text类型 if($MsgT=="text"){ $key = trim($postObj->Content); $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <Content><![CDATA[%s]]></Content> </xml>"; $msgType = "text"; //生成短网址 $dwzapi = "http://api.t.sina.com.cn/short_url/shorten.json?source=3271760578&url_long=".$key; $dwzpost = file_get_contents($dwzapi); $dwzjsondecode = json_decode($dwzpost,true); //发送 $contentStr = $dwzjsondecode[0]['url_short']; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; exit; }else{ $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <Content><![CDATA[%s]]></Content> </xml>"; $msgType = "text"; //发送 $contentStr = "请发送链接"; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; exit; } //如果用户发的event（事件）类型 if($MsgT=="event"){ $Event = $postObj->Event; if ($Event==subscribe) { $contentStr = "欢迎关注"; }else{ $contentStr = "希望您下次关注，但您收不到此条消息了"; } $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[%s]]></MsgType> <Content><![CDATA[%s]]></Content> </xml>"; $Title = $postObj->Title; $Description = $postObj->Description; $Url = $postObj->Url; $msgType = 'text'; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; exit; } }else{ echo "不对"; exit; } } $echoStr = $_GET["echostr"]; //如果有$echoStr说明是对接 if (!empty($echoStr)) { //对接规则 $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 ){ echo $echoStr; }else{ echo ""; exit; } }else{ responseMsg(); } ?>
配置方法：
1、登录公众号
2、打开基本配置
3、填写上面代码的url
Token在代码里面自己设置，要对应的，EncodingAESKey随机生成。
4、然后启用这个配置，然后去公众号发送一个url看看！
