Question

当我下载这两个相同的链接时 a link！和http://files.sparklingclient.com/099_2010.07.09_WP7_Phones_In_The_Wild.mp3 它们都可以通过IE下载。但是当我在wp7下载时，lans可以下载第一个显示错误“”远程服务器返回错误：NotFound。“” 我不知道为什么.is webURL不适合wp7？

Answer 1

请尝试更改

request.Method = "Post"

到

request.Method = "Get"

Answer 2

如果您在模拟器上遇到此问题，您是否尝试过运行Fiddler？它将拦截HTTP请求，您可以查看对服务器的调用是否是您期望的调用。

请记住在启动Fiddler后关闭/重新打开模拟器，以便它能够接收代理。

错误的SSL证书也会发生NotFound响应。这似乎与您的问题无关，但需要记住一些事项。

当试图下载一个MP3;发生错误“远程服务器返回错误：NotFound。”
