Retrofit @body with @multipart having Issue

Question

Image Multipart in class type object.

case 1. (Which I had done)

Service params:

{\"id\":\"1\",\"name\":\"vishal\",\"image/file\":\"\"} 
         


        

Answer 1

this works for me.

What I did was add every additional params using:

MultipartBody.Part Partname = MultipartBody.Part.createFormData("ParamName", "Value");

Mabe you don't need to create another body, but just add others params apart from the file or whatever you are sending. finally at the interface I put as a params every bodypart that I need.

@Multipart
@POST("api/service/uploadVideo")
Call<ResponseBody> uploadVideoToServer(
        @Part MultipartBody.Part video,
        @Part MultipartBody.Part param2,
        @Part MultipartBody.Part param3 ....
);

Answer 2

You can also use a Map with RequestBody as value and string as keys to add parameters and you can send this using Multipart and PartMap.

Check the following code, hope it will help :

@Multipart
@POST("/add")
Call<ResponseBody> addDocument(@PartMap Map<String,RequestBody> params);

Map<String, RequestBody> map = new HashMap<>();

map.put("user_id", RequestBody.create(MediaType.parse("multipart/form-data"), SessionManager.getInstance().getCurrentUserId()));
map.put("doc_name", RequestBody.create(MediaType.parse("multipart/form-data"), CommonUtils.removeExtension(textFile.getName())));
map.put("doc_category", RequestBody.create(MediaType.parse("multipart/form-data"), category));
map.put("doc_image_file", RequestBody.create(MediaType.parse("multipart/form-data"), imageFile));
map.put("doc_text_content", RequestBody.create(MediaType.parse("multipart/form-data"), body));
map.put("doc_update_time", RequestBody.create(MediaType.parse("multipart/form-data"), "" + new Date(textFile.lastModified())));
