使用System.Net.WebRequest获取无效的uri [英] Getting invalid uri with System.Net.WebRequest

问题描述

在网页浏览器中实际加载网站之前，编写一个测试网站响应的脚本。  使用上面的类方法，当我没有"http：//"时，我收到以下错误在"www.xxxxx"之前网站部分：

异常调用"创建"用"1"表示"1"。参数："无效的URI：无法确定URI的格式。"

在Desktop\Scripts\function.ps1:39 char：48

+ $ HTTP_Request = [System.Net.WebRequest] :: Create（" $ b"）  

但是当我在其中添加http时会验证该网站。  我的理解是http通常会附加到系统中的网站请求中吗？

有什么想法吗？我错过了什么吗？

谢谢大家。

你的意思是什么？"http通常总是附加到系统内的网站请求"？什么是"系统"？

来自文档：
https://msdn.microsoft.com/en-us/library/0aa3d588%28v=vs.110%29.aspx".NET Framework包括对
http：// ， https：// ， ftp：// 的支持和 file：// URI方案。"，因此您必须在URi中提供正确的协议，以便Create方法能够知道该怎么做。

Writing a script that tests the response to a website before actually loading it in web browser.  Using the class method above I am getting the following error when I don't have "http://" before the "www.xxxxx" part in site:

Exception calling "Create" with "1" argument(s): "Invalid URI: Theformat of the URI could not be determined."

At Desktop\Scripts\function.ps1:39 char:48
+ $HTTP_Request = [System.Net.WebRequest]::Create ("$b") 

However when I do add the http in it verifies the site.  My understanding is that http is usually always appended to a site request within the system?

Any thoughts? Am I missing something?

thanks all.

What do you mean by "http is usually always appended to a site request within the system"? What is "the system"?

From the documentation: https://msdn.microsoft.com/en-us/library/0aa3d588%28v=vs.110%29.aspx "the .NET Framework includes support for the http://, https://, ftp://, and file:// URI schemes.", so you must provide the correct protocol in the URi for the Create method to be able to know what to do.
