问题描述
Hi, I wrote an application(VB.Net) with XmlHttp object (COM) to do some operations in the exchange server. This application works fine. Now , I want to write the same application with HttpRequest(.Net) instead of XmlHttp, but always When I try to get a response from a query, I get the following error : The remote sever returned an error404) Not Found. Here some lines of the application: '***** Save the attachment ******* ' sUrlAttach is the url of an attachment in the exchange 代码块 推荐答案
1）你得到什么错误？ 2）您是否检查过相同的项目 - 使用OWA并确保该项目退出？ 3）当我们请求/响应时，还验证您是否使用正确的编码来收集URI / URL电话？ 4）确认我们获得了正确的URI / URL？5）确认我们是否通过了有效的网络凭证？ 注意： ===== 1）.Net应用程序不支持MSXML。请参阅我的博文： http ：//blogs.msdn/deva/archive/2008/10/23/nutshell-msxml-is-not-supported-in-net-applications.aspx 。使用System.XML并尝试。 2）如果我们获得404，请确保您正确枚举附件。您可以使用 X-MS-ENUMATTS方法 执行此操作。 3）使用GET方法获取附件，而不是直接调用响应流。 如果您有问题仍然让我知道... 希望这有助于。· 1) What error do you get? 2) Have you checked the same item resides in exchange - use OWA and make sure that the item exits?3) Also verify do you use proper encoding to collect URI/URL's when we do request/response calls?4) Verify we get proper URI/URL's?5) Verify that we pass valid network credentials?Note: =====1) MSXML is not supported with .Net applications. Please refer my blogpost: blogs.msdn/deva/archive/2008/10/23/nutshell-msxml-is-not-supported-in-net-applications.aspx. Use System.XML and try that.2) If we're getting 404 then, make sure that you properly enumerate the attachments. You can use X-MS-ENUMATTS Method to do this.3) Use GET method to get the attachments, instead of calling the response stream directly.still if you have issue let me know...Hope this helps.
