httpcomponent 学习

1.获取浏览器实例，并且设置，请求超时，等待数据超时时间

 private static final int REQUEST_TIMEOUT = 10*1000;//设置请求超时10秒钟  
   private static final int SO_TIMEOUT = 10*1000;  //设置等待数据超时时间10秒钟  
   
   public HttpClient getHttpClient(){  
    BasicHttpParams httpParams = new BasicHttpParams();  
    HttpConnectionParams.setConnectionTimeout(httpParams, REQUEST_TIMEOUT);  
    HttpConnectionParams.setSoTimeout(httpParams, SO_TIMEOUT);  
    HttpClient client = new DefaultHttpClient(httpParams);  
    return client;  
}  

2。下载实例

HttpClient httpClient = new DefaultHttpClient(httpParams);
				HttpGet httpGet = new HttpGet(params[0]);
				HttpResponse httpResponse = httpClient.execute(httpGet);
				HttpEntity httpEntity = httpResponse.getEntity();
				total = (int) httpEntity.getContentLength();
				
				bar.setMax(total);
				File file2 = new File(path);
				createPath(file2);
				String fileName =	params[0].substring(params[0].lastIndexOf("/")+1,params[0].length());
				File file = new File(path + fileName);
				fileNameAbsolute = file.getAbsolutePath();
				inputStream = httpEntity.getContent();
				fos = new FileOutputStream(file);
				byte[] bytes = new byte[1024];
				int numread;
				while ((numread = inputStream.read(bytes)) != -1) {
					fos.write(bytes, 0, numread);
					count += numread;
				}
				fos.flush();
