c# - 是否可以使用 servicestack 上传文件和发布数据？

Question

我希望能够发布一个文件并作为该发布的一部分添加数据。

这是我的:

            var restRequest = new RestRequest(Method.POST);

            restRequest.Resource = "some-resource";
            restRequest.RequestFormat = DataFormat.Json;

            string request = JsonConvert.SerializeObject(model);
            restRequest.AddParameter("text/json", request, ParameterType.RequestBody);

            var fileModel = model as IHaveFileUrl;

            var bytes = File.ReadAllBytes(fileModel.LocalStoreUrl);

            restRequest.AddFile("FileData", bytes, "file.zip", "application/zip");


            var async = RestClient.ExecuteAsync(restRequest, response =>
            {
                if (PostComplete != null)
                    PostComplete.Invoke(
                        new Object(),
                        new GotResponseEventArgs
                            <T>(response));
            });

它可以正常发布文件，但数据不存在 - 这甚至可能吗？

[更新]

我修改了代码以使用多部分 header :

            var restRequest = new RestRequest(Method.POST);

            Type t = GetType();
            Type g = t.GetGenericArguments()[0];

            restRequest.Resource = string.Format("/{0}", g.Name);
            restRequest.RequestFormat = DataFormat.Json;
            restRequest.AddHeader("content-type", "multipart/form-data");

            string request = JsonConvert.SerializeObject(model);
            restRequest.AddParameter("text/json", request, ParameterType.RequestBody);

            var fileModel = model as IHaveFileUrl;

            var bytes = File.ReadAllBytes(fileModel.LocalStoreUrl);

            restRequest.AddFile("FileData", bytes, "file.zip", "application/zip");


            var async = RestClient.ExecuteAsync(restRequest, response =>
            {
                if (PostComplete != null)
                    PostComplete.Invoke(
                        new Object(),
                        new GotResponseEventArgs
                            <T>(response));
            });

仍然没有运气......有任何指示吗？

我不是 C# 方面的专家，但我在 Grails/Java 中对多部分请求使用了相同的原则。

一些指针(ServiceStack/C#)
Multipart Form Post
MSDN MIME Message
ServiceStack File Attachment

Java对应:
Posting File and Data as JSON in REST Service

希望对您有所帮助。
