Drupal 7服务模块节点资源attach_file端点

Question

我正在实施一个Xamarin Form移动应用，允许使用服务模块节点资源将照片发布到Drupal。 http://xxxx.com/ {端点} /节点/ 4 / attach_file

我可以从POSTMAN发帖了

我尝试使用c＃HttpClient实现，但仍然得到响应，例如＆＃34; 401：缺少必需的参数field_name＆＃34;

请帮助我的代码：

var httpClient = new HttpClient(new NativeMessageHandler());
httpClient.Timeout.Add(new TimeSpan(0, 0, 30));
httpClient.BaseAddress = new Uri(BaseAddress);

var content = new MultipartFormDataContent();                 
var streamContent = new StreamContent(g_media.GetStream());            
streamContent.Headers.ContentDisposition = ContentDispositionHeaderValue.Parse("form-data");
streamContent.Headers.ContentDisposition.Parameters.Add(new NameValueHeaderValue("field_name", "field_receipt_image"));       
content.Add(streamContent,"files[file]");               

var response = await httpClient.PostAsync("node/4/attach_file", content);
response.EnsureSuccessStatusCode();

我遇到了同样的问题，并使用RestSharp解决了它。这是我用来将文件上传到Drupal的代码：

    var restClient = new RestClient("http:XXXXXX/attach_file");
    var request = new RestRequest(Method.POST);
    request.AddFile("files[file]", fileName);
    request.AddParameter("field_name", field);
    IRestResponse response = restClient.Execute(request);
