You can use the usual <code>WebRequest</code> and <code>HttpWebRequest</code> classes provided by the .NET framework.

<pre><code>$request = [System.Net.WebRequest]::Create('http://example.com')
# do something with $request
</code></pre>

It's no different from using the same classes and APIs from C#, except for the syntactic differences to PowerShell.

PowerShell v3 also brings <code>Invoke-WebRequest</code> and a few others.

<pre><code>$client = new-object system.net.webclient

PS: With Powershell v3.0, you have <code>Invoke-WebRequest</code> and <code>Invoke-RestMethod</code> cmdlets which can be used for similar purposes

blocks|key|4238158|text|如果所有其他方法都失败了，可以使用http://curl.haxx.se中的Curl。您可以设置所有内容，包括证书处理、POST等。这并不微妙，但它可以工作并处理所有奇怪的情况；例如，您可以设置--insecure标志来忽略证书名称问题、过期或测试状态。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4238159|entityMap|0|LINK|mutability|MUTABLE|url|http://curl.haxx.se/^0|H|J|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

If all else fails, use Curl from <a href="http://curl.haxx.se" rel="nofollow">http://curl.haxx.se</a> . You can set everything, including certificate handling, POSTs, etc. Not subtle, but it works and handles all of the odder cases; e.g. you can set the --insecure flag to ignore certificate name issues, expiration, or test status.

You can create HTTP, HTTPS, FTP and FILE requests using Invoke-WebRequest cmdlet. This is pretty easy and gives many options to play around.

<pre><code>Invoke-WebRequest -Uri "http://google.com"
