最近看挺多人问这个接入流程的，大部分不是很完整，我给大家写一下，大家可以看下。 一.首先把自己设为开发者 二.配置公众号 1.开发者密码一定要保存，之后是看不到的 2.白名单一定要把自己服务的ip放里面 3.服务器地址要和下面文件ping通，不然通过不了
<?php define("TOKEN", "写上面自己填的token");//自己定义的token 就是个通信的私钥 $wechatObj = new wechatCallbackapiTest(); $wechatObj->valid(); //$wechatObj->responseMsg(); class wechatCallbackapiTest { public function valid() { $echoStr = $_GET["echostr"]; if($this->checkSignature()){ echo $echoStr; exit; } } public 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; $keyword = trim($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 = '你好啊'; $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; }else{ echo '说说话吧'; } }else { echo '说说话吧'; 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; } } } ?>晚上把登入和微信获取openid绑定再一起写了，大家可以参考一下
