I have already asked a lot of questions about creating an application with the login function, one of the steps to create such an application is to create an interface for correct operation, first I used this interface:

@POST("/{login}/{password}") Call<LoginRequest> savePost(@Field("id") Integer id, @Field("password") String password);

then I found out that on the server they are waiting for me to have clean json, and so I send the form to the server, and I started using this code for the interface:

 @POST("/{login}/{password}") Call<LoginRequest> savePost(@Body LoginRequest body);

and after replacing the first option with me, the second studio swears at the savepost method:

resulted line:

 mAPIService.savePost(id, password).enqueue(new Callback<LoginRequest>()

You can see my previous questions, and it seems that I started to work a little, but now I'm confused and there are problems with converting data from input fields into json. If anyone knows how to help me I will be very grateful.

  • @POST("/{login}/{password}") - correct this to the correct login path or add the corresponding parameters with the annotation @Path - woesss
  • Is the correct path to the server address? if so, is it necessary to wipe the word login at the end, or does the server need to insert / v1 / login completely - Andrew Goroshko
  • What is the address given to you and write. Only the path is specified relative to baseUrl - that is, if .baseUrl("http://exemple.com") , and the request address is http://exemple.com/v1/login , the path will be @POST("/v1/login") - woesss
  • Perhaps the wrong body imported - by import code show - Serge Markov
  • This one seems to have disappeared, but another one got out)) thanks. - Andrew Goroshko
