SharePoint 2010:此页面的安全验证无效 [英] SharePoint 2010: The security validation for this page is invalid

问题描述

这是我用于检索项目的 Javascript 代码，它是一个 SharePoint 2010 (SP) 列表.

here's my Javascript code to retrieve items is a SharePoint 2010 (SP) list.

var clientContextPath = "/path/site1";
var clientContext = new SP.ClientContext(clientContextPath);
var oList = clientContext.get_web().get_lists().getByTitle(list); 
var camlQuery = new SP.CamlQuery(); 
...

但是，如果我想从其他站点检索，即

However, if I want to retrieve from other site i.e.

var clientContextPath = "/path/site2";

然后相同的代码生成异常此页面的安全验证无效".这是在同一个域内，所以与XSS无关.

then same code generates exception " The security validation for this page is invalid". This is within the same Domain, so it's not something to do with XSS.

有趣的是，当我使用另一个站点时，相同的代码也能正常工作

Interestingly, same code works fine when I use another Site

var clientContextPath = "/path/site3";

请帮忙.谢谢.

推荐答案

我刚刚尝试过这个解决方案，我确信它不会奏效，但是……它确实奏效了！基本上，它是一个从 SharePoint 收集新令牌的 Ajax 请求.

I've just tried this solution, and I was sure it was not going to work but...it did! Basically it's an Ajax request to gather the new token from SharePoint.

$.ajax({
        url: projecturl + "/_api/contextinfo",
        method: "POST",
        headers: { "Accept": "application/json; odata=verbose"},
        success: function (data) {
            $('#__REQUESTDIGEST').val(data.d.GetContextWebInformation.FormDigestValue);

            EnsureScriptFunc('sharing.js', 'DisplaySharingDialog', function () { DisplaySharingDialog(projecturl) });

        },
        error: function (data, errorCode, errorMessage) {
            alert(errorMessage)
        }
    });
