Question

我正在研究如何使用VoiceBase API上传媒体文件。我尝试使用HttpClient（包含MultipartFormDataContent和FormUrlEncodedContent），RestClient，WebClient和WebRequest。但它没有奏效。

以下是我尝试过的代码：

var client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "xxxx");
MultipartFormDataContent form = new MultipartFormDataContent();
form.Add(new StringContent("http:/xx.mp3"), "media", "testFile.mp3");
HttpResponseMessage response = await client.PostAsync("https://apis.voicebase.com/v2-beta/media", form);
HttpContent responseContent = response.Content;
using (var reader = new StreamReader(await responseContent.ReadAsStreamAsync()))
{
   var a = reader.ReadToEndAsync();
   return response;
}

API返回此错误：

"status": 400,
"errors": 
  {
    "error": "We have identified 1 error in your request: (1) Your upload was rejected because the media file not be successfully parsed (80 bytes )."
  },
"reference": "3D00BCA8:A910_0A40E32A:01BB_5949122A_69009:79C6"
}

修改

我也试过二进制数据：

var client = new HttpClient();
client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", "xxxx");
MultipartFormDataContent form = new MultipartFormDataContent();
form.Add(new ByteArrayContent(File.ReadAllBytes(@"C:\Users\xxxx.mp3")), "media", "xxxx.mp3");
HttpResponseMessage response = await client.PostAsync("https://apis.voicebase.com/v2-beta/media", form);
HttpContent responseContent = response.Content;
using (var reader = new StreamReader(await responseContent.ReadAsStreamAsync()))
{
    var a = reader.ReadToEndAsync();
    return response;
}

对于二进制数据，我遇到了以下错误：

{
"status": 400,
"errors": 
{
"error": "We have identified 1 error in your request: (1) We could not download the URL"
}
,
"reference": "3D00BCA8:DFF5_0A40E32A:01BB_59491448_6F33E:79C6"
}

Answer 1

我今天需要这样做，所以我试图在nuget包中完成V3 API的工作： https://www.nuget.org/packages/VoiceBaseV3/

当我得到时间时，我也会在GitHub上得到它

Answer 2

form.Add(...)的第一个参数需要是实际文件内容的数据流，而不是字符串。为此，您可以创建如下的新内存流：new MemoryStream(File.ReadAllBytes(localfilePath))

Answer 3

试试这个：

var content = new StreamContent(new FileStream(@"C:\Users\xxxx.mp3", FileMode.Open));
content.Headers.ContentType = new MediaTypeHeaderValue("audio/mp3");

MultipartFormDataContent form = new MultipartFormDataContent();
form.Add(content, "media", "xxxx.mp3");

Answer 4

如果您使用的是V3，则可以使用Swagger根据您的偏好语言生成客户端代码 https://voicebase.readthedocs.io/en/v3/how-to-guides/swagger-codegen.html
