java - 改造空响应

Question

你好，我和我大学的团队决定创建一个应用程序，健身房的客户可以看到他/她的锻炼列表，我们正在使用改造来获取 json。早期这段代码工作得很好，但突然停止工作，现在我从回调中得到空响应和状态 200。

image with the log.d 200 and null response

抱歉我的英语不好。

我的 JSON

{
"0":{
"id":"1",
"nome":"Fernanda Kondrat", 
"peso":"67.4",
"altura":"172",
"imc":"22.8",
"login":"fefe",
"senha":"1234"},
"lista_exercicios":[
{
"id":"1",
"id_aluno":"1",
"nome":"supino reto",
"num_serie":"3",
"num_repeticao":"10"
},
{
"id":"2",
"id_aluno":"1",
"nome":"agachamento hack",
"num_serie":"3",
"num_repeticao":"10"
},
{
"id":"3",
"id_aluno":"1",
"nome":"barra fixa",
"num_serie":"3",
"num_repeticao":"10"
 },
{
"id":"4",
"id_aluno":"1",
"nome":"leg press",
"num_serie":"4",
"num_repeticao":"10"
}
]
}

现在是我的 MainActivity.java

        }

                startActivity(intent1);
            }else{
                Toast.makeText(MainActivity.this, resposta.getRETORNO() +" ,Verifique usuário e senha" , Toast.LENGTH_SHORT).show();
            }*/
        }

        @Override

    }

public RestServices getRestService(){
    return REST_ADAPTER.create(RestServices.class);
}



public interface RestServices{

    @GET("/getExercicios.php")
    void setUsuarioLoginDTO(
            @Query("LOGIN") String login,
            @Query("SENHA") String senha,
            Callback<RespostaLogin> callbackResposta
    );
}

}

Answer 1

在接口(interface)“RestService”中，更改为:

  @GET("/getExercicios.php")

修改为:

  @GET("getExercicios.php")

删除“/”，因为它已经被附加。

谢谢，编码愉快
