如何使用Retrofit向traccar API发出请求？

Question

我已经试过提出请求，但我做不到。

这是我正在使用的Retrofit界面。使用会话调用，我正在执行基本的HTTP身份验证。

public interface APIService {

@POST("/users")
@FormUrlEncoded
Call<Users> saveUserPost(@Header("Authorization") String credentials,
                         @Field("admin") Boolean admin,
                         @Field("email") String email,
                         @Field("name") String name,
                         @Field("password") String password);

@POST("/session")
Call<List<Session>> openSession(@Body Session session);

}

这是我的活动的onCreate方法，在其中，我尝试登录并验证用户是否已注册。

Retrofit.Builder builder = new Retrofit.Builder()
            .baseUrl("http://http://192.168.1.72:8082/api/")
            .addConverterFactory(GsonConverterFactory.create());

    Retrofit retrofit = builder.build();

    APIService apiService = retrofit.create(APIService.class);
    Session session = new Session();
    session.setPassword("admin");
    session.setEmail("admin");

    Call<List<Session>> call = apiService.openSession(session);

    call.enqueue(new Callback<List<Session>>() {
        @Override
        public void onResponse(Call<List<Session>> call, Response<List<Session>> response) {
            switch (response.code()) {
                case 200:
                    Toast.makeText(getApplicationContext(), "error = 200", Toast.LENGTH_LONG).show();
                    break;
                case 400:
                    Toast.makeText(getApplicationContext(), "error = 400", Toast.LENGTH_LONG).show();
                    break;
                case 401:
                    Toast.makeText(getApplicationContext(), "error = 401", Toast.LENGTH_LONG).show();
                    break;
                case 404:
                    Toast.makeText(getApplicationContext(), "error = 404", Toast.LENGTH_LONG).show();
                    break;
                case 405:
                    Toast.makeText(getApplicationContext(), "error = 405", Toast.LENGTH_LONG).show();
                    break;
                default:
                    Toast.makeText(getApplicationContext(), ""+response.isSuccessful(), Toast.LENGTH_LONG).show();
                    break;
            }
        }

        @Override
        public void onFailure(Call<List<Session>> call, Throwable t) {

        }
    });

您可以查看Traccar Manager的本机版本以获取示例：

https://github.com/tananaev/traccar-manager-android/tree/native

它使用Retrofit。下面是界面：

public interface WebService {

    @FormUrlEncoded
    @POST("/api/session")
    Call<User> addSession(@Field("email") String email, @Field("password") String password);

    @GET("/api/devices")
    Call<List<Device>> getDevices();

    @GET("/api/commandtypes")
    Call<List<CommandType>> getCommandTypes(@Query("deviceId") long deviceId);

    @POST("/api/commands")
    Call<Command> sendCommand(@Body Command command);

}
