1.首先http://square.github.io/okhttp/这是官网地址
2.最简单的调用,同步跟异步调用,
public static void sendHttps(String url){ OkHttpClient client=new OkHttpClient(); Request request=new Request.Builder().url(url).build(); try { Response response=client.newCall(request).execute(); if (response.isSuccessful()){ System.out.println(response.body().string()); } } catch (IOException e) { e.printStackTrace(); } } public static void sendAsync(String url){ OkHttpClient client=new OkHttpClient(); Request request=new Request.Builder().url(url).build(); client.newCall(request).enqueue(new Callback() { @Override public void onFailure(Call call, IOException e) { } @Override public void onResponse(Call call, Response response) throws IOException { if (response.isSuccessful()){ System.out.println(response.body().string()); } } }); }
可以用了,第二篇介绍请求头介绍
