xxx是不是一个有效的虚拟路径？ [英] xxx is not a valid virtual path?

问题描述

我用的XmlDataSource 是这样的：

<asp:XmlDataSource ID="xmlDataSource1" runat="Server" DataFile="https://myurl.xml" ></asp:XmlDataSource>

作为数据源到我的 rotater 控制。

但我得到下面的异常所有的时间：

but i get the following exception all the time :

的https：//myurl.xml 是不是有效的虚拟路径

https://myurl.xml is not a valid virtual path.

虽然我试图链接和外部有一个XML文件

Although i tried the link externally and there's an xml file

推荐答案

忽略我的previous答案。显然，的XmlDataSource 不喜欢https网址为数据文件：

Ignore my previous answer. Apparently the XmlDataSource does not like https URLs as the DataFile:

// works
xmlDataSource1.DataFile = "http://code.google.com/feeds/p/google-code-prettify/svnchanges/basic";
// does not work
xmlDataSource1.DataFile = "https://code.google.com/feeds/p/google-code-prettify/svnchanges/basic";

写code的一些额外的线路从https下载XML数据源，如：

Write a few extra lines of code to download the XML from https source like:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://code.google.com/feeds/p/google-code-prettify/svnchanges/basic");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
StreamReader reader = new StreamReader(response.GetResponseStream()); 
string str = reader.ReadToEnd();
// save it or set it as the .Data property of XmlDataSource
