错误在改造连接

Question

我的界面

@POST("/insert.php") 
void login(Callback<Response> callback); 

Java代码

Retrofit adapter = new Retrofit.Builder() 
         .baseUrl(ROOT_URL) //Setting the Root URL 
         .addConverterFactory(GsonConverterFactory.create()) 
         .build(); //Finally building the adapter 

Register_Retrofit api = adapter.create(Register_Retrofit.class); 


api.login(new Callback<Response>() { 
    public void onResponse(Call<Response> call, Response<Response> response) { 

    } 

    public void onFailure(Call<Response> call, Throwable t) { 

    } 

}); 

Answer 1

您的登录方法返回空隙发生，所以你需要定义它是这样的：

@POST("/insert.php") 
Call<Void> login(); 

然后，拨打登录方法请试试这个：

Retrofit adapter = new Retrofit.Builder() 
         .baseUrl(ROOT_URL) //Setting the Root URL 
         .addConverterFactory(GsonConverterFactory.create()) 
         .build(); //Finally building the adapter 

Register_Retrofit api = adapter.create(Register_Retrofit.class); 
Call<Void> loginCall = api.login(); 
loginCall.enqueue(new Callback<Void>() { 
    public void onResponse(Call<Void> call, Response<Void> response) { 
      ... 
    } 

    public void onFailure(Call<Void> call, Throwable t) { 
      ... 
    } 
});
