我有一个应用程序，我使用“发布”方法将一些数据发送到第三方应用程序。然后，第三方应用程序使用我发布的数据运行一些 java，然后它为我提供了一个 html 页面。我是否有任何可能以编程方式进行审查这个渲染页面的源代码找到一些数据就可以了？
NameValueCollection data = new NameValueCollection();
data.Add("v1", "val1");
data.Add("v2", "val2");
HttpClass.RedirectAndPOST(this.Page, "http://DestUrl/Default.aspx", data);
public static void RedirectAndPOST(Page page, string destinationUrl,
NameValueCollection data)
{
//Prepare the Posting form
string strForm = PreparePOSTForm(destinationUrl, data);
//Add a literal control the specified page holding
//the Post Form, this is to submit the Posting form with the request.
page.Controls.Add(new LiteralControl(strForm));
}
public static void RedirectAndPOST(Page page, string destinationUrl,
NameValueCollection data)
{
//Prepare the Posting form
string strForm = PreparePOSTForm(destinationUrl, data);
//Add a literal control the specified page holding
//the Post Form, this is to submit the Posting form with the request.
page.Controls.Add(new LiteralControl(strForm));
}
private static String PreparePOSTForm(string url, NameValueCollection data)
{
//Set a name for the form
string formID = "PostForm";
//Build the form using the specified data to be posted.
StringBuilder strForm = new StringBuilder();
strForm.Append("<form id=\"" + formID + "\" name=\"" +
formID + "\" action=\"" + url +
"\" method=\"POST\">");
foreach (string key in data)
{
strForm.Append("<input type=\"hidden\" name=\"" + key +
"\" value=\"" + data[key] + "\">");
}
strForm.Append("</form>");
//Build the JavaScript which will do the Posting operation.
StringBuilder strScript = new StringBuilder();
strScript.Append("<script language="'javascript'">");
strScript.Append("var v" + formID + " = document." +
formID + ";");
strScript.Append("v" + formID + ".submit();");
strScript.Append("</script>");
//Return the form and the script concatenated.
//(The order is important, Form then JavaScript)
return strForm.ToString() + strScript.ToString();
}
