android-实例-网络互交-post get请求（依赖okhttp）

我的实例仅供参考配置配置1-权限在AndroidManifest.xml中配置uses-permission android:nameandroid.permission.INTERNET /配置2-下载关联相关包插件记得同步更新操作implementation com.squareup.okhttp3:okhttp:3.5.0 implementation com.squareup.okio:okio:1.11.0 implementation com.google.code.gson:gson:2.9.0在工程下新建文件夹network新建类HttpClient.java类import okhttp3.OkHttpClient;

} private static class SingleTon{ public static final HttpClient INSTANCE new HttpClient(); } /** * 获取单例 * return */ public static HttpClient getInstance(){ return SingleTon.INSTANCE; } /** * 获取OkHttpClient * return */ public OkHttpClient getClient() { return client;
