我正在尝试运行一个简单的测试应用程序来学习Retrofit。总是调用CREATE TABLE new_table_name
AS
SELECT *
FROM old_table_name
WHERE 1 = 2;
方法,请帮助我。我所做的一切如下:
onFailure
MainActivity
public class MainActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
method();
}
public void method()
{
final String BASE_URL = "http://192.168.1.7/";
Retrofit retrofit = new Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
ApiService service = retrofit.create(ApiService.class);
Call<ResponseBody> call = service.login();
call.enqueue(new Callback<ResponseBody>(){
@Override
public void onResponse(Response<ResponseBody> response, Retrofit retrofit)
{
// TODO Auto-generated method stub
if (response.isSuccess())
{
Log.i("mok","S");
ResponseBody rb = response.body();
}
else
{
Log.i("mok","F");
com.squareup.okhttp.ResponseBody rb = response.errorBody();
}
}
@Override
public void onFailure(Throwable t)
{
Log.i("mok",t.getCause()+"");//This is null
Log.i("mok","T");//This is shown in LogCat
finish();
}
});
}
}
RespnseBody
public class ResponseBody
{
private String username;
private String password;
public ResponseBody(String username, String password)
{
this.setUsername(username);
this.setPassword(password);
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
ApiService
public interface ApiService
{
@POST("test_retrofit.php")
public Call<ResponseBody> login();
}
: //位于www目录(在我的计算机上运行wampserver)
test_retrofit.php
编辑:(在iagreen的有用提示之后)
例外是:
java.net.SocketTimeoutException:10000ms后无法连接到/192.168.1.7(端口80)
答案 0 :(得分:1)
您的设备似乎无法连接到服务器。您是否正在测试改装的同一设备上进行测试?另一种选择是设备位于不同的网络上。 192.168.x.x是私有IP,因此如果手机不在同一子网上,则无法找到服务器。或者,事实证明,您需要确保您的防火墙允许连接到您的服务器。

删除BASE_URL的最后一个斜线并将其放在@POST的开头(&#34; test_retrofit.php&#34;)=&gt; @POST(&#34; /test_retrofit.php")
