Question

我正在尝试将mp4视频上传到DailyMotion上传API。当我发送文件内容时，我收到如下错误响应。

Id = 31, Status = RanToCompletion, Method = "{null}", 
Result = "{\"error\":\"missing file\",\"seal\":\"4a24a4c8a51771d9d3b8bcd4462e721b\"}"

我在.net 4.5中使用C＃并生成以下调用：

POST [[UPLOAD URL]] HTTP/1.1
Accept: */*
Content-Type: multipart/form-data; boundary="c83ccd81-39f7-4167-a8f1-74ab63eb4219"
Host: upload-01.sv6.dailymotion.com
Content-Length: 9893501
Expect: 100-continue

--c83ccd81-39f7-4167-a8f1-74ab63eb4219
Content-Disposition: form-data; name="file"; filename="TESTFILE.mp4"
Content-Type: application/octet-stream

[[[FILE BINARY]]]

我已成功使用DailyMotion的CURL示例上传。使用Fiddler，CURL生成以下内容：

POST [[UPLOAD URL]] HTTP/1.1
User-Agent: curl/7.33.0
Host: upload-02.sv6.dailymotion.com
Accept: */*
Connection: Keep-Alive
Content-Length: 9893509
Expect: 100-continue
Content-Type: multipart/form-data; boundary=------------------------a49610ec11411f2a

--------------------------a49610ec11411f2a
Content-Disposition: form-data; name="file"; filename="TESTFILE.mp4"
Content-Type: application/octet-stream

[[FILE BINARY]]

文件二进制文件看起来不错，我看到的唯一区别是连接和用户代理标头。研究Connection头，看起来像HTTP / 1.1不需要Keep-Alive。我尝试了几种不同的用户代理（Mozilla，CURL，IE）但响应没有变化。

我很欣赏任何有关正在发生的事情的见解。谢谢！

编辑补充代码：

mediatype = "video/mp4"
name = "file"
filename = "file"
data = {byte[9893291]}

 public async Task UploadRequest(string mediatype, string name, string filename, byte[] data)
    {
        using(HttpClient httpClient = new HttpClient())
        {
            var requestContent = new MultipartFormDataContent();

            httpClient.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("*/*"));

            var videoContent = new ByteArrayContent(data);
            videoContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data");
            videoContent.Headers.ContentDisposition.Name = "\"file\"";
            videoContent.Headers.ContentDisposition.FileName = filename;
            videoContent.Headers.ContentType = MediaTypeHeaderValue.Parse("application/octet-stream");

            requestContent.Add(videoContent, name);

            Apirequest.HttpRequestMessage.Content = requestContent;

            Apirequest.HttpResponseMessage = httpClient.SendAsync(Apirequest.HttpRequestMessage).Result;
            Apirequest.HttpResponseMessage.EnsureSuccessStatusCode();

        }
    }

编辑更新了以下帮助

编辑：请求了修复程序的代码示例。它如下：

videoContent.Headers.ContentDisposition.FileName = "\"" + name + "\"";

Answer 1

经过调查，看起来负责处理文件上传的 nginx-upload-module 看起来并不理解HTTP标头中引用的内容边界，{{3无论如何，它不是在HTTP中定义边界的标准方法。看起来您用来制作请求的C＃库可能遵循multipart/digest内容类型的标准而不是multipart/form-data（参见第7.2.4节）。请检查这是否是您可以控制的，然后重新测试。
