有一次看到国光用了这个功能好像还蛮屌的,于是自己也用了一下,用的过程中发现一个问题,就是会错过很多消息,不能及时的回复,本着研究的精神,便有了以下的文章

魔改Daovoice添加实时监控

分析源码

先发一个消息,看整个过程调用了哪些函数

一眼就能看到关键函数

跟进去之后下断点

然后再来来发送一遍消息,看看消息在哪个变量中,最后确定是在t.body里面

加上alert测试是否正常捕捉到消息

对接钉钉

直接上php代码了,大家伙自己看着改吧

<?php
function request_by_curl($remote_server, $post_string)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $remote_server);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 5);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json;charset=utf-8'));
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    // 不用开启curl证书验证
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    $data = curl_exec($ch);
    //$info = curl_getinfo($ch);
    //var_dump($info);
    curl_close($ch);
    return $data;
}

function XXXXXXXXXX($content,$webhook){
    if (!empty($content)){
        $data = [
             'msgtype' => 'link',
             'link' => [
                 'text' => '您的博客有人留言说: '.$content,
                 'title' => '您的Daovoice有新的即时消息,请点击查看',
                 'picUrl' => '',
                 'messageUrl' => "http://dashboard.daovoice.io/app/XXXX/inboxes/XXXX/conversations/"
             ]
         ];
         $textString = json_encode($data);
        $result = request_by_curl($webhook, $textString);
    }else{
                $data = [
             'msgtype' => 'link',
             'link' => [
                 'text' => '您有可能收到了一张图片',
                 'title' => '您的Daovoice有新的即时消息,请点击查看',
                 'picUrl' => '',
                 'messageUrl' => "http://dashboard.daovoice.io/app/XXXX/inboxes/XXXX/conversations/"
             ]
         ];
         $textString = json_encode($data);
        $result = request_by_curl($webhook, $textString);
    }
}

function main(){
    $content = $_POST['daovoice_content'];
$verify = $_POST['verify'];

$webhook = "https://oapi.dingtalk.com/robot/send?access_token=XXXX";
    if($verify == "True"){
   XXXXXXXXXX($content,$webhook); 
}
}

main();

魔改源码

先下载JS

然后在sendMessage函数结尾添加代码

var httpRequest = new XMLHttpRequest();
httpRequest.open("POST","https://XXXX/XXXX.php",true);
httpRequest.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
httpRequest.send("daovoice_content="+t.body+"&verify=True");
httpRequest.onreadystatechange = ()=>{
    if(httpRequest.status == 200){
        console.log("留言成功");
		        }
		    }

整体代码效果如下

总结

还可以做更多的优化,例如获取到匿名者的ID,拼装组成URL这样钉钉收到消息,点击链接即可跳转回复
