retrofit.HttpException：HTTP 400錯誤的請求android（關閉）

Question

strong text我試圖實現基本用戶註冊。 我正在使用RxJava和翻新（v2測試版）。

URL: http://momento-w03d.c9users.io/register 
Fields 
username 
password 
fullname 
email 

當我使用郵遞員送這4個領域的表單數據 的迴應是：["success"]

有我做錯了，或者是因爲我使用CLOUD9服務器的東西。

我是新來改造，我無法理解我犯了什麼錯誤。 非常感謝您的時間。

類AuthServiceFactory

public class AuthServiceFactory { 
    private static Retrofit.Builder builder = 
      new Retrofit.Builder() 
        .baseUrl(AuthService.BASE_URL) 
        .addConverterFactory(GsonConverterFactory.create()) 
        .addCallAdapterFactory(RxJavaCallAdapterFactory.create()); 


    public static <S> S createService(Class<S> clazz) { 
     final Retrofit retrofit = builder.build(); 
     S service = retrofit.create(clazz); 
     return service; 
    } 
} 

接口AuthService

public interface AuthService { 
    String BASE_URL = "http://momento-w03d.c9users.io"; 

    @FormUrlEncoded 
    @POST("/register") 
    Observable<Message> register(@Field("username") String username, 
           @Field("password") String password, 
           @Field("email") String email, 
           @Field("fullname") String fullname); 
} 

Model類消息

public class Message { 
    private String message; 

    public String getMessage() { 
     return message; 
    } 
} 

發送請求

AuthService authService = AuthServiceFactory.createService(AuthService.class); 
      authService.register("lorem", "12345678", "lorem@gmail.com", "lorem imposium") 
        .subscribeOn(Schedulers.newThread()) 
        .observeOn(AndroidSchedulers.mainThread()) 
        .subscribe(new Subscriber<Message>() { 
         @Override 
         public void onCompleted() { 

         } 

         @Override 
         public void onError(Throwable e) { 
          e.printStackTrace(); 
         } 

         @Override 
         public void onNext(Message message) { 
          System.out.println(message.getMessage()); 
         } 
        });

public interface AuthService { 
    String BASE_URL = "http://momento-w03d.c9users.io"; 

    @POST("/register") 
    Observable<Message> register(@Body RegisterBody body); 
} 

public class RegisterBody { 
    String username; 
    String password; 
    String fullname; 
    String email; 

    public RegisterBody(String username, String password, String fullname, String email) { 
     this.username = username; 
     this.password = password; 
     this.fullname = fullname; 
     this.email = email; 
    } 
}
