Web services webservice单向和新SPSite(myUrl)
我对打开moss站点的单向web方法有问题(可能是因为在单向web方法中上下文为null) 是否可以重写此代码以删除空引用异常?(没有单向属性,我没有例外) 例外情况是:Web services webservice单向和新SPSite(myUrl),web-services,sharepoint,moss,Web Services,Sharepoint,Moss,我对打开moss站点的单向web方法有问题(可能是因为在单向web方法中上下文为null) 是否可以重写此代码以删除空引用异常?(没有单向属性,我没有例外) 例外情况是: [2304] Error:Object reference not set to an instance of an object.

我找到了解决问题的方法。创建新的HttpContext。现在的问题是: 这是正确的解决方案,还是我没有考虑到的暗示? 我用于更改上下文的方法如下:
//Call this before call new SPSite()
private static void ChangeContext(string webUrl)
{
Trace.TraceInformation("ChangeContext");
HttpContext current = HttpContext.Current;
HttpRequest request = new HttpRequest("", webUrl, "");
HttpContext.Current = new HttpContext(request, new HttpResponse(new StringWriter(CultureInfo.CurrentCulture)));
HttpContext.Current.User = current.User;
}

我看到的唯一含义是您实际上正在使用一个新的HttpContext 嗯……嗯:)
无论如何,如果您还设置了输入和输出过滤器,这将产生影响。例如,如果您将WebServiceExtensions(WSE)与您自己的输入和输出过滤器一起使用。在这种情况下,您应该将数据存储在HttpContext中(在输入和输出过滤器中),并使用该上下文。这样您就可以只使用一个httpContext,而不是创建第二个httpContext,并防止在扩展软件时出现任何错误 我看到的唯一含义是您实际上正在使用一个新的HttpContext 嗯……嗯:)

SPWeb web = SPContext.Current.Web

SPWeb web = SPContext.Current.Web
