Retrofit trailing slash on relative urls

Question

Does Retrofit remove the trailing slash from a relative url for an endpoint? I have tried adding the trailing slash on one of my endpoints but when i step through with a debugger and i look at the Call object, if I drill into the delete.relativeUrl it does not show the trailing slash.

You need to manually add the slash at the end of the base URL endpoint.

Let's say you have this two instances of retrofit:

No Slash

Retrofit retrofitNoSlash = new Retrofit.Builder()
        .baseUrl("https://example.com/api/v5")
        .build();

@GET("something"): https://example.com/api/v5something
@GET("/something"): https://example.com/something

With Slash

Retrofit retrofitWithSlash = new Retrofit.Builder()
        .baseUrl("https://example.com/api/v5/")
        .build();

@GET("something"): https://example.com/api/v5/something
@GET("/something"): https://example.com/something

so: add the trailing slash manually

You can try the following code. Just remove slash with base url because back slash already added begin with end point url in GET method.

NetworkInterface.java

@GET("/baking.json")
Call<List<ResponseModel>> getRecepies();

public static Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(URLs.RECEPIES_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .build();

URLs.java

  public static String RECEPIES_URL="https://d17h27t6h515a5.cloudfront.net/topher/2017/May/5907926b_baking";
