如何满足或绕过Asp.net WebForms的viewstate验证?

I`ve got a link in a Webforms page which opens in a new window, and posts to a form other than the page itself. This is done like this:

我在一个新窗口打开的Webforms页面中有一个链接，并将它发布到页面本身之外的表单。这是这样做的:

JS:

JS:

var submitFunc = function(){
    document.forms[0].action = 'http://urlToPostTo/somePage.aspx';  
    document.forms[0].target = '_blank'; 
    document.forms[0].submit();
}

The link:

链接:

<input type="hidden" id="myDataId" value="12345" />     
<a href="javascript:submitFunc();">Search</a>

As you can see, this overrides the target of the main <form>, and attempts to post to a different page. The whole point is that this should post/submit to a different page, while avoiding passing the data of "myDataId" as a Get parameter.

如您所见，这将覆盖主

The above code would work, but causes an error due to viewstate validation.

上面的代码可以工作，但是由于viewstate验证导致了一个错误。

Question: Is there any way for me to either satisfy the requirements here, or somehow bypass the viewstate validation so I can post my data this way?

问:我是否有办法满足这里的需求，或者绕过viewstate验证，以便以这种方式发布数据?

Sounds like you just need to change the PostBackUrl of the button that submits the form.

听起来您只需更改提交表单的按钮的PostBackUrl。

A simple example PostToPage1.aspx that posts to PostToPage2.aspx (instead of a postback):

一个简单的例子PostToPage1。发送到PostToPage2的aspx。aspx(不是回邮):

<form id="form1" runat="server">
<div>
    <asp:TextBox ID="text1" runat="server" /><br />
    <asp:TextBox ID="text2" runat="server" />
    <asp:Button ID="btn1" runat="server" PostBackUrl="~/PostToPage2.aspx" />
</div>
</form>

You can then inspect the Request in PostToPage2.aspx to check if it's a POST, etc. and then access the Request.Form collection in the Request in Page_Load.

然后可以在PostToPage2中检查请求。aspx检查它是否是POST，等等，然后访问请求。在Page_Load中的请求中的表单集合。

An overly simplified sample for PostToPage2.aspx (do add proper validation):

PostToPage2的一个过于简化的示例。aspx(添加适当的验证):

if (!Page.IsPostBack && Request.RequestType == "POST")
    {
        if (Request.Form != null && Request.Form.Keys.Count > 0)
        {
           .....

Hth...

Hth……
