Question

我正在使用ngrok将本地的php项目放到网络中。我需要在登录操作中获取用户的ID。我的Android给了我

响应{协议= http / 1.1，代码= 404，消息=未找到，URL = {http://ab873755.ngrok.io/site/login?login=123&pass=123456}

在改装的Android Studio中无法获得响应。网址正确。在邮递员中检查过

当我将此URL放入Postman时，一切正常，并给出正确的响应。该页面返回

{“ user_id”：1}

package com.example.backgroundservice.ui.login;

import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;

public class WResponce {
    @SerializedName("user_id")
    @Expose
    private String user_id;

    public String getUserId() {
        return user_id;
    }

    public void setUserId(String user_id) {
        this.user_id = user_id;
    }

Answer 1

放入基数url = http://ab873755.ngrok.io。您不应将路径放在基本URL中。将路径放入@GET("sites/login").

确保您的ngrok网址处于活动状态。好像已经过期了

Answer 2

您使用的URL在POSTMAN中不起作用。

注意事项

1）是否在授权中传递任何内容。
2）是否在标题中发送任何内容

邮递员中的响应不正确（屏幕截图）

无法在Android Studio改装中获得回应
