问题描述

我有一个Windows 8.1应用程序试图点击一个web api方法，但是它给出了错误代码403.

I have a windows 8.1 application which try to hit a web api method but it gives error code 403.

由于httpwebrequest属性中的空值而导致错误。当我尝试在请求标头中设置User-Agent值但无法设置时。

The error is comming due to null value in httpwebrequest property.When i am try to set the User-Agent value in request header but unable to set.

我们如何在httpwebrequest中设置User-Agent值 对于Windows 8.1应用程序？

Can you edit your title tag based on this page https://social.msdn.microsoft.com/Forums/windowsapps/en-US/b479e984-ca39-4b34-a6b7-85194b54d8bd/guide-to-posting-subject-line-tags?forum=wpdevelop

所以你在Windows 8.1 Universal上app，我是对的吗？

So you are on a Windows 8.1 Universal app, am I right?

如果是这样，请参考以下内容：
https://stackoverflow.com/questions/7454301/is-it-possible-to-modify-the-user-agent -for-a-winrt-httpwebrequest 但请理解，在Windows 8.1平台上，您的HttpWebRequest API很差，实际上我建议您升级为使用UWP
pl atform。您将有更多API可供使用。

If so, please refer to this so thread: https://stackoverflow.com/questions/7454301/is-it-possible-to-modify-the-user-agent-for-a-winrt-httpwebrequest But please understand that on Windows 8.1 platform your HttpWebRequest API is poor and actually I would recommend you to upgrade to use UWP platform. You will have more API available to use.

祝您好运，
