Synology Surveillance API帮助。抓取快照？

Question

如何从监控站Web API抓取“快照”？我想要做的是抓取一个快照，并将其提供给一个网页。

对Synology Surveillance的Web API如何工作不是很熟悉(我一般是编程新手)。我试着通读帮助。可以在此处找到web API帮助。Surveillance Station Web API

当我在浏览器中输入这段代码时，我希望得到一个快照JPG

http://MyNASip:5000/webapi/entry.cgi?camStm=1&version="8"&cameraId=1&api="SYNO.SurveillanceStation.Camera"&preview=true&method="GetSnapshot"

我的理解对吗？

取而代之的是，我在浏览器中得到了这个

{"error":{"code":105},"success":false}

我在/var/log/messages中得到了以下内容

2018-02-05T13:15:03-06:00 DS215j synoscgi_SYNO.SurveillanceStation.Camera_8_GetSnapshot[15020]: group_is_admin_group_member_by_uid.c:14 SYNOUserGetByUID(4294967295) failed [0x1D00 user_get_by_uid.c:129

是否存在身份验证问题？

Answer 1

API的第16页显示错误105是“用户权限不足”。按照第14页所示的工作流程，您应该能够完成您想要的工作。首先尝试调用登录方法(第21页)，然后请求快照。

这可能会有所帮助:每当您看到GET /webapi/...时，都可以将其更改为http://MyNASip:5000/webapi/...并使用浏览器发送请求。

抓取快照的代码必须先从api获取路径、摄像头路径和SID，然后才能访问快照。下面是我的代码的摘录(如下所示)

$user = "xxxxxxx";  // Synology username with rights to Surveillance station 
$pass = "xxxxxxx";  // Password of the user entered above 
$ip = "192.168.xxxxxx";  // IP-Adress of your Synology-NAS 
$port = "5000";  // default port of Surveillance Station 
$http = "http"; // Change to https if you use a secure connection 
$cameraID = xx;
$cameraStream = xx];
$vCamera = 7; //Version API SYNO.SurveillanceStation.Camera
$vAuth = ""; 
if ($cameraStream == NULL) { 
    $cameraStream = "0"; 
} 
//Get SYNO.API.Auth Path (recommended by Synology for further update)
    $json = file_get_contents($http.'://'.$ip.':'.$port.'/webapi/query.cgi?api=SYNO.API.Info&method=Query&version=1&query=SYNO.API.Auth');
    $obj = json_decode($json);
    $AuthPath = $obj->data->{'SYNO.API.Auth'}->path;
// Authenticate with Synology Surveillance Station WebAPI and get our SID 
    $json = file_get_contents($http.'://'.$ip.':'.$port.'/webapi/'.$AuthPath.'?api=SYNO.API.Auth&method=Login&version=6&account='.$user.'&passwd='.$pass.'&session=SurveillanceStation&format=sid'); 
    $obj = json_decode($json); 
//Check if auth ok
if($obj->success != "true"){
    echo "error";
    exit();
}else{
//authentification successful
    $sid = $obj->data->sid;

//Get SYNO.SurveillanceStation.Camera path (recommended by Synology for further update)
        $json = file_get_contents($http.'://'.$ip.':'.$port.'/webapi/query.cgi?api=SYNO.API.Info&method=Query&version=1&query=SYNO.SurveillanceStation.Camera');
        $obj = json_decode($json);
        $CamPath = $obj->data->{'SYNO.SurveillanceStation.Camera'}->path;

// Get Snapshot
if ($cameraID != NULL) { 
        // Setting the correct header so the PHP file will be recognised as a JPEG file 
        header('Content-Type: image/jpeg'); 
        // Read the contents of the snapshot and output it directly without putting it in memory first 
        readfile($http.'://'.$ip.':'.$port.'/webapi/'.$CamPath.'?camStm='.$cameraStream.'&version='.$vCamera.'&cameraId='.$cameraID.'&api=SYNO.SurveillanceStation.Camera&preview=true&method=GetSnapshot&_sid='.$sid); 
}

这是我编写的php脚本的摘录，用于将所有调用连接到synology Surveillance API。你可以抓取快照，mjpeg，开始，停止，发送邮件等。

代码非常简单，请随意寻找灵感。
