Android 访问网络系列(二)

上篇文章是采用HttpUrlConnection接口进行访问，实际上Android已经为我们封装了一个HttpClient接口，这是由Apache提供的。GET方法的操作代码如下：

<pre name="code" class="java">private void surfInternet(){
	//HttpGet连接对象
	HttpGet httpRequest = new HttpGet("http://photocdn.sohu.com/20111123/Img326603573.jpg");
	//取得HttpClient对象
	HttpClient httpClient = new DefaultHttpClient();
	try {
	//请求HttpClient，取得HttpResponse
		HttpResponse httpResponse = httpClient.execute(httpRequest);
		//请求成功
		if(httpResponse.getStatusLine().getStatusCode()==HttpStatus.SC_OK){
		//取得相关信息 取得HttpEntiy
			HttpEntity httpEntity = httpResponse.getEntity();
			InputStream is = httpEntity.getContent();
			bt = BitmapFactory.decodeStream(is);
			is.close();
		}
	} catch (Exception e) {
		// TODO: handle exception
	}
	runOnUiThread(new Runnable() {
		
		@Override
		public void run() {
			// TODO Auto-generated method stub
			iv.setImageBitmap(bt);
		}
	});
}
