httpclient中怎么使用post方法获取html的源码

Answer 1

public void clientPost()
{
String httpUrl="http://10.0.2.2:8080/JDemo/android/httpget2.jsp";
// HttpPost连接对象
HttpPost httpRequest=new HttpPost(httpUrl);
//使用NameValuePair来保存要传递的Post参数
List<NameValuePair> params=new ArrayList<NameValuePair>();
//添加要传递的参数
params.add(new BasicNameValuePair("par","HTTP_Client_android_Post"));
try {
//设置字符集
HttpEntity httpentity=new UrlEncodedFormEntity(params,"gb2312");
//请求httpRequest
httpRequest.setEntity(httpentity);
//取得HttpClient对象
HttpClient httpclient=new DefaultHttpClient();
//请求HttpCLient，取得HttpResponse
HttpResponse httpResponse=httpclient.execute(httpRequest);
//请求成功
if(httpResponse.getStatusLine().getStatusCode()==HttpStatus.SC_OK)
{
//取得返回的字符串
String strResult=EntityUtils.toString(httpResponse.getEntity());
text1.setText(strResult.trim());
}else
{
text1.setText("请求错误！");
}
} catch (ClientProtocolException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}catch(Exception e)
{
text1.setText(e.getMessage().toString());
}
}
纯手打，望采纳！
