GET、POST请求封装类

okHttp3封装Get、Postff调用，使用之前先加入okHttp3的依赖：

implementation 'com.squareup.okhttp3:okhttp:3.4.1' //okhttp3

然后在AndroidManifest.xml中加入网络权限

<uses-permission android:name="android.permission.INTERNET" />

okHttp3的封装类：

package com.example.recycleview2.http;

    import org.json.JSONException;
    import org.json.JSONObject;
