How to pass Map parameters or object to POST request via Retrofit?

Question

I have a problem with passing Map parameters or object to Retrofit POST request.

I follow square, kdubb labs tutorials and this thread and I couldn\'t figure it out.

Answer 1

In retrofit 2.0 you have to do this way:

@FormUrlEncoded
    @POST(Constant.API_Login)
    Call<UserLoginPost> userLogin(@FieldMap Map<String, String> params);

Answer 2

This feature is still not supported by the Retrofit 1.2.2, however you can compile your own version from the master branch with this feature or wait for the next release.

Update:

It's available in Retrofit version 1.5.0 ! (ref Anton Golovin answer)

Answer 3

Well, now we can implement this thing (version 1.5.0).

@FormUrlEncoded
@POST("/oauth/access_token")
void getToken(
    @FieldMap Map<String, String> params, 
    Callback<FacebookLoginUserResponse> callback
);
