Image File Not Going To Server Using Retrofit 2 Post Method

Hi friends please help me out here i am new for the retrofit i am trying use the post method in the retrofit to send the image file by converting it into base64 format but it is no

Solution 1:

In order to POST a file, we need to enable Multipart.Part define a part inside the Multipart. MultipartBody.Part is the type that we want to use for a file / image. Non-file Part should use RequestBody type with expected fieldname

Service / Endpoint interface

interfaceService {
    @Multipart@POST("/")
    Call<ResponseBody> postImage(@Part MultipartBody.Part image, @Part("name") RequestBody name);
}

Retrofit call, postImage parameter

Filefile=newFile(filePath);

RequestBodyreqFile= RequestBody.create(MediaType.parse("image/*"), file);
MultipartBody.Partbody= MultipartBody.Part.createFormData("upload", file.getName(), reqFile);
RequestBodyname= RequestBody.create(MediaType.parse("text/plain"), "upload_test");

retrofit2.Call<okhttp3.ResponseBody> req = service.postImage(body, name);
req.enqueue(newCallback<ResponseBody>() {
    @OverridepublicvoidonResponse(Call<ResponseBody> call, Response<ResponseBody> response) { 
        // Do Something
    }

    @OverridepublicvoidonFailure(Call<ResponseBody> call, Throwable t) {
        t.printStackTrace();
    }
});

Go through this githib example for more details

EDIT

Parameters along with Image would be as follows

@Multipart@POST("users/{id}/user_photos")
Call<models.UploadResponse> postImage(@Path("id") int userId, @PartMap Map<String, RequestBody> params);

Request parameters

//All the String parameters
Map<String, RequestBody> map = newHashMap<>();
map.put("methodName", toRequestBody(methodName));
map.put("userid", toRequestBody(userId));
map.put("name", toRequestBody(name));

//To put your image file as wellFilefile=newFile("file_name");
RequestBodyfileBody= RequestBody.create(MediaType.parse("image/png"), file);
map.put("relative_image\"; filename=\"some_file_name.png\"", fileBody);

// This method  converts String to RequestBodypublicstatic RequestBody toRequestBody(String value) {
    RequestBodybody= RequestBody.create(MediaType.parse("text/plain"), value);
    return body ;
}

//To send your request
call = service.postImage(body, params);
