Android Studio：retrofit2：图像和字符串的多部分连接失败

Question

private void Dialog_profile_pic() {
    // create upload service client
    File file = new File(selectedImagePath);

    // create RequestBody instance from file
    RequestBody requestFile =
            RequestBody.create(MediaType.parse("multipart/form-data"), file);

    // MultipartBody.Part is used to send also the actual file name
    MultipartBody.Part body =
            MultipartBody.Part.createFormData("memFile", file.getName(), requestFile);

    // add another part within the multipart request
    RequestBody description =
            RequestBody.create(
                    MediaType.parse("multipart/form-data"), ApiResultCode.getApiKey());

    RequestBody description2 =
            RequestBody.create(
                    MediaType.parse("multipart/form-data"), ApiResultCode.getApiType());

    Call<LoginPicture> loginPictureCall = RequestClient.getInstance()
            .loginPicture(description, description2, body);

    loginPictureCall.enqueue(new Callback<LoginPicture>() {
        @Override
        public void onResponse(Call<LoginPicture> call, Response<LoginPicture> response) {
            //CONNECTION SUCCESS
            LoginPicture NewUser = response.body();
            if (NewUser.getResponsedata().getResultCode() == 100) {
                Log.e("DEBUG", "CONNECTION result: CONGRATS");
            } else {

                Log.e("DEBUG", "CONNECTION result: " + NewUser.getResponsedata().getResultCode() + NewUser.getResponsedata().getResultMessage());
            }
        }

        @Override
        public void onFailure(Call<LoginPicture> call, Throwable t) {
            //CONNECTION FAIL
            Log.e("DEBUG", "CONNECTION result: FAIL" );
        }
    });
}

\

public interface ApiInterface {
@Multipart
    @POST("/memberController/joinUploadProfile.json")
    Call<LoginPicture> loginPicture(@Part("apiKey") RequestBody apiKey, @Part("apiType") RequestBody apiType, @Part("memFile") MultipartBody.Part file); //multi part

\ 我正在尝试使用 retrofit2 传递两个字符串参数和一个图像文件，但我无法建立连接。任何人都可以帮我找到我需要做什么？我已经为此苦苦挣扎了 2 天。

Answer 1

//请求客户端API接口

@Multipart
    @POST("URL.json")
    Call<LoginPicture> loginPicture(@PartMap() Map<String, RequestBody> mapPhoto); //multi part

//在activity

private void Dialog_profile_pic(final Uri selectedImageUri) {
    // create upload service client
    File file = new File(selectedImagePath);
    HashMap<String, RequestBody> map = new HashMap<>();
    RequestBody description =
            RequestBody.create(
                    MediaType.parse("text/plain"),"content1");
    RequestBody description2 =
            RequestBody.create(
                    MediaType.parse("text/plain"), "content2");

    // create RequestBody instance from file
    RequestBody requestFile =
            RequestBody.create(MediaType.parse("image/jpeg"), file);
    map.put("memFile\"; filename=\""+file.getName(),requestFile);
    map.put("apiKey",description);
    map.put("apiType", description2);

    Call<LoginPicture> loginPictureCall = RequestClient.getInstance()
            .loginPicture(map);
    loginPictureCall.enqueue(new Callback<LoginPicture>() {
        @Override
        public void onResponse(Call<LoginPicture> call, Response<LoginPicture> response) {
                Picasso.with(Activity_create.this).load(NewUser.getResponsedata().getResultObject()).into(iv_profile_pic);
            } else {
                Log.e("DEBUG", "CONNECTION result: " + NewUser.getResponsedata().getResultCode() + NewUser.getResponsedata().getResultMessage());
            }
        }

        @Override
        public void onFailure(Call<LoginPicture> call, Throwable t) {
            //통신 실패 시
            Log.e("DEBUG", "CONNECTION result: FAIL");
        }
    });
}

//现在有效
