首先我应该说我已经关注了下面几乎所有的问题和论坛帖子
应用程序中的服务器错误...检测到潜在危险的 Request.Form 值
避免“检测到潜在危险的 Request.Form 值”</a>
在 asp.net 中从客户端检测到潜在危险的 Request.Form 值
所有提到的要添加 <httpRuntime requestValidationMode = "2.0" />或<pages validateRequest ="false" />在 web.config 文件中的线程，但这对我不起作用。
一旦我这样做并开始调试，就会出现这种错误
实际上，我正在尝试将 HTML 文件加载到富文本编辑器内容中，然后单击另存为 PDF按钮将富文本编辑器内容保存到 PDF 文件
这些是相关的控制器类方法
[ValidateInput(false)]
public ActionResult output_xhtml()
{
PrepairEditor(delegate(Editor editor)
{
editor.LoadHtml("~/example.html");
});
return View();
}
[HttpPost]
[ValidateInput(false)]
public ActionResult output_xhtml(string m)
{
Editor theeditor = PrepairEditor(delegate(Editor editor)
{
});
theeditor.SavePDF("~/aaa.pdf");
return View();
}
PrepairEditor() 方法
protected Editor PrepairEditor(Action<Editor> oninit)
{
Editor editor = new Editor(System.Web.HttpContext.Current, "editor");
editor.ClientFolder = "/richtexteditor/";
editor.ContentCss = "/Content/example.css";
//editor.ClientFolder = "/Content/richtexteditor/";
//editor.ClientFolder = "/Scripts/richtexteditor/";
editor.Text = "Type here";
editor.AjaxPostbackUrl = Url.Action("EditorAjaxHandler");
if (oninit != null) oninit(editor);
//try to handle the upload/ajax requests
bool isajax = editor.MvcInit();
if (isajax)
return editor;
//load the form data if any
if (this.Request.HttpMethod == "POST")
{
string formdata = this.Request.Form[editor.Name];
if (formdata != null)
editor.LoadFormData(formdata);
}
//render the editor to ViewBag.Editor
ViewBag.Editor = editor.MvcGetString();
return editor;
}
//this action is specified by editor.AjaxPostbackUrl = Url.Action("EditorAjaxHandler");
//it will handle the editor dialogs Upload/Ajax requests
[ValidateInput(false)]
public ActionResult EditorAjaxHandler()
{
PrepairEditor(delegate(Editor editor)
{
});
return new EmptyResult();
}
这是 PrepairEditor() 方法中发生错误的地方的截图
