我在Windows Server 2008 Enterprise中使用SharePoint Server 2007 Enterprise。我已经部署了一个发布门户。我正在使用VSTS 2008 + C#+ .Net 3.5 + ASP.Net + SharePoint Server 2007 SDK开发ASP.Net Web应用程序。
这是我的代码片段,我收到错误 - “目前GET请求中不允许更新”。任何想法如何解决?
Microsoft.SharePoint.SPException: Updates are currently disallowed on GET requests. To allow updates on a GET, set the 'AllowUnsafeUpdates' property on SPWeb.
protected void Page_Load(object sender, EventArgs e)
{
try
{
SPWebApplication webApp = SPContext.Current.Site.WebApplication;
SPSiteCollection siteCollections = webApp.Sites;
foreach (SPSite item in siteCollections)
{
SPWeb webItem = item.OpenWeb();
webItem.AllowUnsafeUpdates = true;
}
SPSite newSiteCollection = siteCollections.Add("sites/myblog",
"New Sample Site", "New Sample Site Description", 1033, "BLOG#0",
"foo\\foouser", "Owner name", "owneremail@foo.com");
}
catch (Exception ex)
{
Response.Write(ex.ToString() + "\t" + ex.StackTrace);
}
}

添加检查以确保在尝试允许更新之前获得POST而不是GET。确保进行更改的任何内容都通过POST请求而不是使用URL参数和GET进行。
if (IsPostBack)
{
...
}

为什么不允许在GET请求上读/写数据库的问题是因为您的代码可以通过跨站点脚本来利用。 Read about AllowUnsafeUpdates consequences here
无论如何,如果你愿意,你可以将这个SPWeb.AllowUnsafeUpdates设置为true,但是像这样使用它:
try {
web.AllowUnsafeUpdates = true;
...
}
finally {
web.AllowUnsafeUpdates = false;
}
