REST API附件错误 [英] Rest API attachment error

问题描述

我在使用bot框架REST API通过Skype频道发送附件时遇到问题.

I've problems sending attachments through a Skype channel using the bot framework REST API.

我能够使用这样的json消息正确发送图像:

I'm able to correctly send images using a json message like this:

{  
   "type":"message",
   "timestamp":"2017-05-22T11:31:36.2281894Z",
   "from":{  
      "name":"MyBot"
   },
   "recipient":{  
      "id":"29:1-Dl1xMx6G2qGya5O5BgTZJhc0fUKOiQLctt74CmwJ3PVJNgkocpf3LY626py9UIO"
   },
   "text":"It works!",
   "attachments": [
        {
            "contentType": "image/jpg",
            "contentUrl": "https://g87a2173.ngrok.io/content/attachments/65f2be10-e61e-424e-9ea1-e05f1002fd19",
            "name": "image.jpg"
        }
    ]
}

但是，如果我发送的图像类型不是图像，则出现错误.

But if I send files with any content type other than image I have an error.

例如，如果我发送

{  
   "type":"message",
   "timestamp":"2017-05-22T11:31:36.2281894Z",
   "from":{  
      "name":"MyBot"
   },
   "recipient":{  
      "id":"29:1-Dl1xMx6G2qGya5O5BgTZJhc0fUKOiQLctt74CmwJ3PVJNgkocpf3LY626py9UIO"
   },
   "text":"Not working!",
   "attachments": [
        {
            "contentType": "audio/wav",
            "contentUrl": "https://g87a2173.ngrok.io/content/attachments/e58bcefa-7060-464f-96ee-78d2795ec80f",
            "name": "audio.wav"
        }
    ]
}

我收到400错误

{
    "error": {
        "code": "BadArgument",
        "message": "Unknown attachment type"
    }
}

用于这些测试的其余端点是

The rest endpoint used for these tests is https://smba.trafficmanager.net/apis/v3/conversations/29%3A1-Dl1xMx6G2qGya5O5BgTZJhc0fUKOiQLctt74CmwJ3PVJNgkocpf3LY626py9UIO/activities

API参考文档指出

附件可以是媒体文件(例如，音频，视频，图像，文件)或 一张丰富的卡

An attachment may be a media file (e.g., audio, video, image, file) or a rich card

那我在哪里错了?

谢谢

推荐答案

我使用C#代码尝试了相同的操作，并得出了相同的结论:在Skype Channel上，我们为此出现了Unknown attachment type异常. 在模拟器和Slack上工作(获得了下载wav文件的链接)

I tried the same with C# code and got the same conclusion: on Skype Channel, we got an Unknown attachment type exception for this. Working on emulator and Slack (got a link to download the wav file)

必须有一个频道限制，或者是一个错误.

There must be a channel limitation yes, or a bug.

无论如何，您都可以尝试使用AudioCard:我已经在C#代码中对其进行了测试，并且可以在Skype上运行:

Anyway you may try to use AudioCard: I tested it (in C# code) and it's working on Skype:
