[英]simulate a web form button click using C# HttpWebRequest
I'm trying to send a post request to simulate pressing a button that resides on a webpage form using C# HTMLWebRequest. 我正在尝试发送一个发布请求,以模拟按下使用C#HTMLWebRequest驻留在网页表单上的按钮。 The form on the webpage looks like the following:
该网页上的表单如下所示:
<form method="post" action="HtmlAdaptor">
<input type="hidden" name="action" value="invokeOp">
<input type="hidden" name="name"
value='somevalue'>
<input type="hidden" name="methodIndex" value="5">
<hr align='left' width='80'>
<h4>java.util.List methodName()</h4>
<p>MBean Operation.</p>
<input type="submit" value="Invoke">
</form>
My code to send the HTML post and read HTML response: 我发送HTML帖子并阅读HTML响应的代码:
string webURL = "http://pageurl";
HttpWebRequest myRequest =(HttpWebRequest)WebRequest.Create(webURL);
myRequest.Method = "POST";
byte[] lbPostBuffer = System.Text.Encoding.GetEncoding(1252).GetBytes(sb.ToString());
myRequest.ContentType = "text/xml; charset=utf-8";
myRequest.ContentLength = lbPostBuffer.Length;
myRequest.Accept = "text/xml";
Stream loPostData = myRequest.GetRequestStream();
loPostData.Write(lbPostBuffer, 0, lbPostBuffer.Length);
loPostData.Close();
HttpWebResponse loWebResponse = (HttpWebResponse)myRequest.GetResponse();
Encoding enc = System.Text.Encoding.GetEncoding(1252);
StreamReader loResponseStream = new StreamReader(loWebResponse.GetResponseStream(), enc);
string lcHtml = loResponseStream.ReadToEnd();
loWebResponse.Close();
loResponseStream.Close();
I have a string builder variable "sb" that gets converted to a byte array to be posted to the site. 我有一个字符串生成器变量“ sb”,该变量被转换为要发送到站点的字节数组。 My problem is I'm not sure what I should be sending in the sb.ToString() to submit the invoke button on that form.
我的问题是我不确定应该在sb.ToString()中发送什么内容以提交该表单上的调用按钮。
我已经通过提琴手找到了请求的格式。
