我将数据发布到表单并且一切运行良好,但之后我需要在POST后输入数据后获取页面的源(html)。
这是可能的,如果是这样的话?
我正在使用此方法进行POST:
string HttpPost(string uri, string parameters)
{
HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create(uri);
webRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.2; rv:9.0.1) Gecko/20100101 Firefox/9.0.1";
webRequest.ContentType = "application/x-www-form-urlencoded";
webRequest.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(parameters);
Stream os = null;
try
{
webRequest.ContentLength = bytes.Length;
os = webRequest.GetRequestStream();
os.Write(bytes, 0, bytes.Length);
}
catch (WebException ex)
{
MessageBox.Show(ex.Message, "HttpPost: Request error",
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
finally
{
if (os != null)
{
os.Close();
}
}
try
{
WebResponse webResponse = webRequest.GetResponse();
if (webResponse == null)
{ return null; }
StreamReader sr = new StreamReader(webResponse.GetResponseStream());
return sr.ReadToEnd().Trim();
}
catch (WebException ex)
{
MessageBox.Show(ex.Message, "HttpPost: Response error",
MessageBoxButtons.OK, MessageBoxIcon.Error);
}
return null;
}
答案 0 :(得分:0)
您的意思是您想要服务器的响应吗?如果是,请阅读HttpWebRequest
的文档,尤其是GetResponse
方法:http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.getresponse.aspx
编辑:感谢您现在发布源代码。这是你需要的基本结构,所以我不清楚你的问题是什么......
