Question

所以我们有一个用java编写的服务器应用程序，它有一个休息服务，您可以以多部分请求的形式上传文件。这是方法的签名

@POST
@Transactional(TxType.REQUIRED)
@Path("/{id}")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public ContentInfo uploadToInstanceFromMultipart(UploadRequest uploadRequest, @PathParam(JsonKeys.ID) String id) {

正如你所看到的，没有什么特别之处，只是一个邮政服务。但另一方面，我们正在编写一个ms office插件（VSTO），它使用RestSharp将文件发送到该服务。

  void Application_DocumentBeforeSave(Word.Document Doc, ref bool SaveAsUI, ref bool Cancel)
    {
        var client = new RestClient("...");
        client.Authenticator = new HttpBasicAuthenticator(...);
        var request = new RestRequest("api/content/{id}", Method.POST);
        var name = Doc.Name;
        var contentId = getContentId(name);
        var fileName = getName(name);

        request.AddUrlSegment("id", contentId); 
        request.AddFile(fileN, Doc.Path + "\\" + Doc.Name, "application/msword");

        IRestResponse response = client.Execute(request);
        var content = response.Content;
        MessageBox.Show(content);

我在这里也看不到任何特别的内容，但在保存文件时（因此将其发送到服务器），服务器会响应以下异常

(default task-33) Generic exception: javax.ws.rs.WebApplicationException: Processing of multipart/form-data request failed. Stream ended unexpectedly

归结为

Caused by: org.apache.commons.fileupload.MultipartStream$MalformedStreamException: Stream ended unexpectedly

请问有什么想法吗？
