OkHttp的简单使用方法

package com.example.networktest;import okhttp3.OkHttpClient;import okhttp3.Request;/** * Created by lenovo on 2019/3/19. */public class HttpUtil { ???public static void sendOkHttpRequest(String address,okhttp3.Callback callback){ ???????OkHttpClient client=new OkHttpClient(); ???????Request request=new Request.Builder().url(address).build(); ???????client.newCall(request).enqueue(callback);//内部自动打开了线程 ???}

 ???public void onClick(View v){ ???????if (v.getId()==R.id.button1){ ??????????// sendRequestWithHttpURLConnection(); ???????????// sendRequestWithOkHttp(); ???????????HttpUtil.sendOkHttpRequest("https://www.qu.la/book/101104/5290362.html",new okhttp3.Callback(){ ???????????????@Override ???????????????public void onResponse(Call call, Response response) throws IOException { ???????????????????String responseData=response.body().string();//获取返回的值 ???????????????????showResponse(responseData);//自己写的方法 ???????????????} ???????????????@Override ???????????????public void onFailure(Call call, IOException e) { ???????????????} ???????????}); ???????} ???}

 ?private ?void showResponse(final ?String response){ ???????runOnUiThread(new Runnable() {//由于子线程不准许操作UI所以使用runOnUiThread方法切换到主线程 ???????????@Override ???????????public void run() { ???????????????text.setText(response); ???????????} ???????}); ???}
