我正在尝试将图片上传到我的应用中的Google Cloud Storage。我有一个有效的网络解决方案，所以我可以看到所有的请求信息。这里是工作网络解决方案的原始请求

这是我使用Retrofit的Request API

 @Multipart
    @POST("/_ah/upload/{key}")
    void imageUpload(@EncodedPath("key") String key,@Part("photo") TypedFile photoFile,Callback<List<ImageUploadResponse>> callback);

这是请求实现

TypedFile photoTypedFile = new TypedFile("image/*", imageFileName);
                    TypedString name = new TypedString("testName");


                    service.imageUpload(key, photoTypedFile, new Callback<List<ImageUploadResponse>>() {
                        @Override
                        public void success(List<ImageUploadResponse> imageUploadResponses, Response response) {
                            Log.d("SignUpActivity", "Status Code = " + response.getStatus());
                            Log.d("SignUpActivity", "response = " + new Gson().toJson(response));
                            if (response.getStatus() < 400) {
                                // request successful (status code 200, 201)
                                ImageUploadResponse result = imageUploadResponses.get(0);
                                Log.d("SignUpActivity", "response = " + new Gson().toJson(result));
                                Toast.makeText(getApplicationContext(), result.imageUrl, Toast.LENGTH_SHORT).show();
                                Log.d("SignUpActivity", "ImagUrl = " + result.imageUrl);
                            }
                        }

                        @Override
                        public void failure(RetrofitError error) {
                            Log.d("SignUpActivity", error.toString());
                        }
                    });

Answer 1

所以，问题是，我得到了空身体，尽管200 Ok回应。几个小时后，我注意到，我需要在Body

中使用特殊的name

Content-Disposition: form-data; name="news_file"; filename="news.txt"\r\n

在此之前，我使用随机名称，它是测试，abc等。但是。此名称是表单的名称，因此这应该是表单的名称，而不是您想要的名称。希望这对某人有所帮助。

在android中，这应该是这样的。我使用改造。

  @Multipart
    @POST("/_ah/upload/{key}")
    void imageUpload(@EncodedPath("key") String key, @Part("news_file") TypedFile photoFile,Callback<List<ImageUploadResponse>> callback);

看一看，@Part与名称相同（例如news_file）

在Android中如何将图像映射到Google云端存储？
