我基本上试图在邮件请求中发送一张照片,其名称user_photo[image]如下图所示:

以下是我考虑过的解决方案的片段:

    Call<models.UploadResponse> uploadPhoto(@Path("id") int userId, @Part MultipartBody.Part file);


        MultipartBody.Part body = MultipartBody.Part.createFormData("user_photo[image]", file.getName(), requestFile);
Call<models.UploadResponse> call = userRequest.uploadPhoto(62, body);



    RequestBody requestFile =
            RequestBody.create(MediaType.parse("image/*"), FileUtils.getFile(PhotoUploadActivity.this, fileUri));
    Call<models.UploadResponse> call = userRequest.uploadPhoto(62, requestFile);

    Call<models.UploadResponse> uploadPhoto(@Path("id") int userId, @Part ("name=\"user_photo[image]\"") RequestBody file);

    @Multipart
        @POST("users/{id}/user_photos")
    Call<models.UploadResponse> uploadPhoto(@Path("id") int userId, @Part("name=\"user_photo[image]\"") RequestBody file);

这是okhttp日志:

也:

我提到的解决方案:

1. https://github.com/square/retrofit/issues/1140
2. https://futurestud.io/blog/retrofit-2-how-to-upload-files-to-server
3. Retrofit - Multipart请求:必需的MultipartFile参数'file'不存在
4. Multipart Retrofit 2.0图片上传
5. https://github.com/square/retrofit/issues/1063

我厌倦了寻找解决方案.有人可以帮忙吗？

Answer 1

在API方面

  @Multipart
  @POST("users/{id}/user_photos")
  Call<SignUpResp> uploadPhoto(@Part("description") RequestBody description, @Part MultipartBody.Part file,(add if more parameter req as like ID,name));

在java文件端

    if (fileUpload != null) {


        /**
         * code for multipart
         */

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

        // MultipartBody.Part is used to send also the actual file name
        MultipartBody.Part body =
                MultipartBody.Part.createFormData("user_photo[image]", fileUpload.getName(), requestFile);

        // add another part within the multipart request
        String descriptionString = "hello, this is description speaking";
        RequestBody description =
                RequestBody.create(
                        MediaType.parse("multipart/form-data"), descriptionString);


        call = userRequest.uploadPhoto(description, body, authData);

    }

Answer 2

您必须将其作为键入的文件发送。

 TypedFile upload_file = new TypedFile("multipart/form-data", new File(your_file_location));

 @Multipart
 @POST("users/{id}/user_photos")
 Call<models.UploadResponse> uploadPhoto(@Path("id") int userId, @Part("name=\"user_photo[image]\"")TypedFile upload_file);

希望能帮助到你
