Request.ValidateInput函数的确切位置

Question

这是Request.ValidateInput函数在ProcessRequest阶段调用的确切位置..？ （在asp.net 2.0中）

Answer 1

RequestValidation在生命周期的早期就会触发。

这些事件＆amp;方法触发，然后在DeterminePostBackMode点终止请求。

• ExecuteStep
• 执行
• BeginProcessRequest
• ProcessRequestInternal
• ProcessRequestWithNoAssert
• 的ProcessRequest
• ProcessRequestMain
• DeterminePostBackMode

这是来自HttprequestValidationException的示例堆栈跟踪。

at System.Web.HttpRequest.ValidateString(String s, String valueName, String collectionName) 
at System.Web.HttpRequest.ValidateNameValueCollection(NameValueCollection nvc, String collectionName) 
at System.Web.HttpRequest.get_Form() 
at System.Web.HttpRequest.get_HasForm() 
at System.Web.UI.Page.GetCollectionBasedOnMethod(Boolean dontReturnNull) 
at System.Web.UI.Page.DeterminePostBackMode() 
at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) 
at System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) 
at System.Web.UI.Page.ProcessRequest() 
at System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) 
at System.Web.UI.Page.ProcessRequest(HttpContext context) 
at ASP.register_aspx.ProcessRequest(HttpContext context) in d:\Temporary ASP.NET Files\belfast\09a30891\d8a3024a\App_Web_fxdlie1w.16.cs:line 0
