改造无法连接到hapi服务器localhost？

标签： java android retrofit2 hapijs

我使用改造作为我的httprequest构建Android应用程序以连接到我的hapi服务器。我的服务器工作正常，我已经在postman和我的WebApps上测试了它。但我的改造无法连接到它。下面是我的代码。为了简单起见，我删除了不必要的行：

LoginActivity.java

        String password = passwordText.getText().toString();

        // TODO: Implement your own authentication logic here.
        Retrofit retrofit = new Retrofit.Builder()

                .build();

        APIService api = retrofit.create(APIService.class);

                    if (returnError(result).isEmpty()) {

                        JSONObject obj;

                        session.setLoginSession(obj.getString("scope"), obj.getString("token"));

                        Intent i = new Intent(LoginActivity.this, MainActivity.class);

                    }
                } catch (JSONException e) {
                    e.printStackTrace();
                }

            }

            .......

APIService.java

/**

public interface APIService {
    @POST("auth")
    Call<UserLogin> login(@Body UserLogin auth);
}

UserLogin.java 

package com.sianghee.reviu.models;

public class UserLogin {
    String email;
    String password;

    public UserLogin(String email, String password) {
        this.email = email;
        this.password = password;
    }
}

每当我点击登录按钮时，它都无法连接到服务器。下面是logcat：

我的登录服务器API网址是： http://127.0.0.1:3000/auth

在此之前注意到Log.w()方法的错误：

  

java.net.ConnectException：无法连接到/127.0.0.1:3000

也许这只是我的常见错误，请帮助。

3 个答案:

答案 0 :(得分：2)

127.0.0.1是您的计算机的本地主机/环回地址a（托管服务器的地址）。 127.0.0.1映射到计算机的IP地址，因此http://127.0.0.1:3000/auth只能从您的计算机访问。

现在，为了从任何其他计算机（例如您的手机）访问http://127.0.0.1:3000/auth，您的计算机（服务器）和设备（电话）应该在同一网络上（例如，相同的Wi-Fi）您需要通过http://IPAddressOfYourMachine:3000/auth访问它。

在MacOs / Linux上，您可以在终端上使用ifconfig命令查找IP地址。在Windows计算机上，命令为ipconfig。 IP地址的格式应为192.168.x.y。

所以最终的BASE_URL应该是http://192.168.x.y:3000

答案 1 :(得分：1)

确保您的手机（仿真器）和计算机位于同一网络中 并以ip地址http://192.168.8.106:3030为例，而不是http://localhost:3030

答案 2 :(得分：0)

改造没有任何问题。问题出在BASE_URL中，用于从Android设备到服务器。

请检查计算机安装服务器的本地IP地址（例如：192.168.1.103），然后用以下示例替换BASE_URL 

public static final String BASE_URL = "http://192.168.1.103:3000";
