Android通過OKhttp從服務器端獲取數據

直接看代碼 

//okHttp的基本使用 --- get方法
String url = "https://api.douban.com/v2/movie/top250?start=0&count=10";
//1,創建OKHttpClient對象
OkHttpClient mOkHttpClient = new OkHttpClient();
//2,創建一個Request
Request request = new Request.Builder().url(url).build();
//3,創建一個call對象
Call call = mOkHttpClient.newCall(request);
//4,將請求添加到調度中
call.enqueue(new Callback() {
@Override
public void onFailure(Request request, IOException e) {
}
@Override
public void onResponse(Response response) throws IOException {
if (response.isSuccessful()) {
final String message = response.body().string();
handler.post(new Runnable() {
@Override
public void run() {
tv_message.setText(message);
progressBar.setVisibility(View.GONE);
}
});
}
}
});
