Issue with Special Characters in Retrofit 2 encoding

问题

So I'm looking to make a request to our api to log in a user, however there is a section that gets encoded in the Retrofit 2 method even though its set as encoded = true. The base url is https://testapi.test.ie The parameter I pass as the serverext is mdc.php?action= However even after setting encoded = true the resulting request body is: https://testapi.test.ie/mdc.php%3Faction=login_user&ts=1482924232742 where I require it to be: https://testapi.test.ie/mdc.php?action=login_user&ts=1482924232742 So I can see the issue is the ? symbol. Below is my retrofit method, if anyone can help with this I would appreciate it in order to achieve the correct

@retrofit2.http.POST("/{serverext}login_user&ts={timestamp}")
@retrofit2.http.Multipart
Call<LoginResponseModel> loginUser(@retrofit2.http.Path(value = "serverext", encoded = true) String server,
                             @retrofit2.http.Part(Constants.USER) String username,
                             @retrofit2.http.Part(Constants.PASS) String password,
                             @retrofit2.http.Path("timestamp") Long timestamp);

回答1:

You use it incorrect. Path is path, Query is query. You need to rewrite your code to use this separately.

@retrofit2.http.POST("{serverext}")
@FormUrlEncoded
Call<LoginResponseModel> loginUser(@retrofit2.http.Path(value = "serverext", encoded = true) String server,
                             @retrofit2.http.Field(Constants.USER) String username,
                             @retrofit2.http.Field(Constants.PASS) String password,
                             @retrofit2.http.Query("timestamp") Long timestamp, 
                             @retrofit2.http.Query("action") String action);

loginUser("mdc.php", username, pass, 42, "login_user")

You need to use @FormUrlEncoded . And you don't need to include package name in all declarations! just import them! its more neat and clean!

  @POST("/{serverext}login_user&ts={timestamp}")
    @Multipart
    @FormUrlEncoded
    Call<LoginResponseModel> loginUser(@Path(value = "server", encoded = true) String server,
                                       @Part(SyncStateContract.Constants.USER) String username,
                                       @Part(SyncStateContract.Constants.PASS) String password,
                                       @Path("timestamp") Long timestamp);
