SharePoint开发中常见的几种错误类型及解决方法！

news 来源：原创 2024/5/19 1:33:46

在sharepoint开发中遇到的一些问题和解决方案

1.错误类型：

The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again.

解决方案:

Microsoft.SharePoint.Administration.SPWebApplication webApp = site.Site.WebApplication;
webApp.FormDigestSettings.Enabled = false;
SPFile spFile = site.Files.Add(fileUpload.FileName, contents);
spFile.Item.Update();
webApp.FormDigestSettings.Enabled = true;
web.AllowUnsafeUpdates = true;
site.AllowUnsafeUpdates = true;

2. 错误类型：

在 sharepoint中报未知错误

解决方案:

在该站点下的配置文件里面修改以下节点

1.<SafeMode MaxControls="200" CallStack="false" DirectFileDependencies="10" TotalFileDependencies="50" AllowPageLevelTrace="false">
改为:
<SafeMode MaxControls="200" CallStack="true" DirectFileDependencies="10" TotalFileDependencies="50" AllowPageLevelTrace="false">

2.<customErrors mode="On " /> 改为:<customErrors mode="Off " />

3.<compilation batch="false" debug="false ">改为； <compilation batch="false" debug="true ">

修改后就会把错误源显示出来,总比报"未知错误"好吧！

3. 错误类型：

Unable to serialize the session state. In 'StateServer' and 'SQL Server' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.

解决方案:

被使用的类必须标记为可序列化！

4.错误类型：

如果配置好的sharepoint,也在同一个域,把用户加进了网站的成员组里面,但是该组里面的成员还是不能访问

解决方案:

请关闭防火墙。![如果报访问受限,则把成员加进网站的成员组里面]

4. 错误类型：

Operation is not valid due to the current state of the object

解决方案:提升权限

SPSecurity.RunWithElevatedPrivileges(delegate() {

SPSite site = new SPSite(http://jianghao:9000 );

SPWeb web = site.OpenWeb();
using (site)

//...

});

或者：

private string GetPictureUrl(string loginName)
{

SPSite site = null;
        SPWeb web = null;
        using (site = new SPSite(mySiteUrl))
        {
            using (web = site.RootWeb)
            {
                web.AllowUnsafeUpdates = true;
                ServerContext ctx = ServerContext.GetContext(site);
                UserProfileManager profileMgr = new UserProfileManager(ctx);
                if (HttpContext.Current != null)
                {
                    if (HttpContext.Current.Items["HttpHandlerSPWeb"] == null)
                    {
                        HttpContext.Current.Items["HttpHandlerSPWeb"] = web;
                    }
                    if (HttpContext.Current.Items["Microsoft.Office.ServerContext"] == null)
                    {
                        HttpContext.Current.Items["Microsoft.Office.ServerContext"] = ctx;
                    }
                }
                if (profileMgr.UserExists(loginName))
                {
                    //Microsoft.SharePoint.Portal.UserProfiles.UserProfile up = upMan.GetUserProfile(loginName);
                    Microsoft.Office.Server.UserProfiles.UserProfile up = profileMgr.GetUserProfile(loginName);
                    if (!string.IsNullOrEmpty(up[PropertyConstants.PictureUrl].Value as string))
                    {
                        return up[PropertyConstants.PictureUrl].Value.ToString();
                    }
                    else { return “”; } }

注意,不能乱提升权限,因为提升权限后一切都是System Account用户的操作!比如是别人回复的博客和 Discussions 的回复人都是"System Account"这个人!这个当然是不对的了!

5.错误类型: Illegal characters in path. 【路径中非法字符。】

A: 在把UserControl配置到sharepoint里面时

<%@ Register src="~/_controltemplates/revolution9000/ [这里换行了]
GroupBlogPostInfo.ascx" tagname="GroupBlogPostInfo" tagprefix="uc1" %> 如果要换行,则可以在 tagname 那里换行！每个属性的值不能截断这个问题太变态！找这个问题郁闷惨了！还是同事Bobby找到的，我可以没有那么好的耐心.

6.错误类型：Visual Studio 2008的代码度量和引用的程序集

在不同的创作后的今天早些时候的过程中，我偶然发现一个错误，同时使用代码度量在Visual Studio 2008的功能。在点击分析菜单，然后点击代码度量的计算解决方案，我遇到的解决方案在几个项目的错误类似于以下内容：发生错误时计算目标文件『E代码度量：\ NotBackedUp \ ...'项目...下面的错误阅读时遇到模块'Microsoft.SharePoint'：无法解析类型：？Ť？对象模型？。英文错误:[Project: Revolution.WebSite
