如何在 Retrofit 2.2.0 的一个请求中 POST Body 和 Multipart 数据

Question

我正在尝试 post @Body 和 @Part 同一 API 请求中的数据

喜欢下面

@Multipart
@POST("AccountService/MultipartProfileImageUpload")
Call<String> updateProfilePic(@Body UserIdCredentials userIdCredentials,@Part MultipartBody.Part file);

但它不起作用我收到错误

@Body parameters cannot be used with form or multi-part encoding. (parameter #1)

请有人帮我解决这个问题

Answer 1

Post 这个

@Multipart
@POST("AccountService/MultipartProfileImageUpload")Call<String> 
updateProfilePic(@Body UserIdCredentials 
userIdCredentials,@Part MultipartBody.Part file);

对此

@Multipart
@POST("AccountService/MultipartProfileImageUpload")Call<String> 
updateProfilePic(@part("params") UserIdCredentials 
userIdCredentials,@Part MultipartBody.Part file);

并在服务器端

获取请求正文作为params

使用下面的代码：

接口：

 @Multipart
@POST("/ws_services.php?action=imageupload")
public void imageupload(@Part("image") TypedFile file, Callback<Example> callback);

Activity.java

                 TypedFile typedFile = new TypedFile("image/*", new File(file.getAbsolutePath()));

                    ApiHandler.getApiService().imageupload(typedFile, new Callback<Example>() {
                        @Override
                        public void success(Example example, Response response) {
                            try {
                                String status = example.getSuccess();
                                if (status.equals("1"))
                                {
                                    Toast.makeText(getApplication(),example.getMessage(),Toast.LENGTH_SHORT).show();

                                }
                                else
                                {
                                    Toast.makeText(getApplication(),example.getMessage(),Toast.LENGTH_SHORT).show();
                                }
                            } catch (Exception e) {

                                Log.e("status", "0");
                            }
                        }

                        @Override
                        public void failure(RetrofitError error) {
                            Log.e("retrofit error log", error.toString());
                        }
                    });

Answer 3

参考This的回答，我做了这样的修改，效果很好。

请求

RequestBody requestBody = RequestBody.create(MediaType.parse("*/*"), file);
        MultipartBody.Part fileToUpload = MultipartBody.Part.createFormData("image", file.getName(), requestBody);
        MultipartBody.Part id = MultipartBody.Part.createFormData("userId", userId);
        //Creating a rest adapter
        ApiInterface apiService =
                ApiClient.getClient().create(ApiInterface.class);

        Call<ProfilePicUpdateResponse> call = apiService.updateProfilePic(id,fileToUpload);
        call.enqueue(new Callback<ProfilePicUpdateResponse>() {
            @Override
            public void onResponse(Call<ProfilePicUpdateResponse> call, Response<ProfilePicUpdateResponse> response) {

                loading.dismiss();
                if (response.isSuccessful()) {
                    Log.e("Success", new Gson().toJson(response.body()));
                }
                else
                {
                    loading.dismiss();
                    csActivity.showMsg(getResources().getString(R.string.something_error));
                }
            }

            @Override
            public void onFailure(Call<ProfilePicUpdateResponse> call, Throwable t) {

                loading.dismiss();
                Log.d("=========>>", t.getMessage().toString());
                Log.d("============>>>", "Failure");
            }
        });

接口类

 @Multipart
    @POST("AccountService/MultipartProfileImageUpload")
    Call<ProfilePicUpdateResponse> updateProfilePic(@Part MultipartBody.Part userId, @Part MultipartBody.Part file);
