微信公众号订阅时回复两条信息

1，第一条是客户信息，第二条是订阅信息
2，先添加客服

function addkf()
{
    $access_token = $this->get_accessToken();
    $url = 'https://api.weixin.qq.com/customservice/kfaccount/add?access_token='.$access_token;

// $data = '{
// “kf_account” : "fangyangeg@",
// “nickname” : “客服1”,
// “password” : “systemsystem”,
// }’;
$data = array(
“kf_account”=>“fangyangeg@hunxiaofa”,
“nickname”=>“客服1”,
“password”=>“systemsystem”
);
$output = $this->wx_post($url,json_encode( $data,JSON_UNESCAPED_UNICODE)); if($output == 0){
echo($output);
}
return false;
}
3，服务器地址URL http://www..cn/index.php/api/index/show
执行服务器地址URL

//连接微信公众号
public function show(){

    //获取随机字符串
    $echoStr = input("echostr");
    if($echoStr){
        // 验证接口的有效性，由于接口有效性的验证必定会传递echostr 参数
        if($this ->checkSignature()){
            echo $echoStr;
            exit;
        }
    }else{
        $this->responseMsg();
    }
}
 //消息推送

public function responseMsg()
{
    //get post data, May be due to the different environments
    $postStr = file_get_contents('php://input');
    //extract post data
    if (!empty($postStr)){

        /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,

        libxml_disable_entity_loader(true);
        $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
        $fromUsername = $postObj->FromUserName;
        $toUsername = $postObj->ToUserName;

        //判断该数据包是否是订阅的事件推送
        if( strtolower( $postObj->MsgType) == 'event'){

                echo $resultStr;
                $this->messageToUserName($contentStr,$fromUsername);
            }
        }

    }else {
        echo "";
        exit;
    }
}

//客服消息
