HttpConnection 联网请求2

//链接url地址

URL url = new URL(path);

//创建 HttpURLConnection对象

HttpURLConnection connection = (HttpURLConnection) url
.openConnection();
// 设置连接超时
connection.setConnectTimeout(5000);
// 设置读取超时
connection.setReadTimeout(5000);
// 设置请求方式
connection.setRequestMethod("GET");


// 连接网络
connection.connect();
// 如果响应码等于200代表请求成功
if (connection.getResponseCode() == 200) {
// 得到服务器返回的信息,是流的形式返回回来的
InputStream inputStream = connection.getInputStream();


BufferedReader bufferedReader = new BufferedReader(
new InputStreamReader(inputStream, "UTF-8"));


String str;
StringBuffer stringBuffer = new StringBuffer();
// 一次读一行
while ((str = bufferedReader.readLine()) != null) {
// 把读到的每一行信息都追加到stringBuffer里
stringBuffer.append(str);
}


String data = stringBuffer.toString();

//这里可做解析Gson封装入类  传给Handler 处理
