Android開發之http請求

    網上很多關於http請求的代碼都沒有用線程的方式，然後請求一直髮送不出去，後來發現是要用線程的方式來發送請求的，就寫成了一個Http請求工具類。

public class HttpRequest{
	Handler handler;
	public HttpRequest(String url,Handler handler){
		this.handler=handler;
		new request(url).start();
	}
	public class request extends Thread {
		String url = null;

		public request(String url) {
			this.url = url;
		}

		public void run() {
			String message = "請求失敗";
			try {
				HttpGet request = new HttpGet(url);
				request.setHeader("charset", "UTF-8");
				HttpClient httpClient = new DefaultHttpClient();
				HttpResponse response = null;
				try {
					response = httpClient.execute(request);
				} catch (Exception e) {
					// TODO: handle exception
					e.printStackTrace();
					Message msg = new Message();
					msg.arg1 = 2;
					handler.sendMessage(msg);
				}

				if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
					message = EntityUtils.toString(response.getEntity());
					Message msg = new Message();
					msg.arg1 = 1;
					msg.obj = pan;
					handler.sendMessage(msg);
				} else {
					Message msg = new Message();
					msg.arg1 = 3;
					handler.sendMessage(msg);
				}
			} catch (Exception e) {
				// TODO: handle exception
				e.printStackTrace();
			}
		}
	}
}
