Powershell Http发布请求

Question

阅读stackoverflow以获得答案，仍无法找到导致此问题的原因..

尝试使用PowerShell连接并发送POST请求，并且无法连接到远程服务器＆＃34;错误。尝试了3个不同的虚拟服务器，如http://posttestserver.com/post.php

脚本：

Get-ExecutionPolicy
[string]$url = "http://posttestserver.com/post.php"
function Execute-HTTPPostCommand()
{
param([string]$target = $null)
#$username = "administrator"
#$password = "mypass"
$webRequest = [System.Net.WebRequest]::Create($target)
$webRequest.ContentType = "text/html"
$post = "abcdefg"
$PostStr = [System.Text.Encoding]::UTF8.GetBytes($Post)
$webrequest.ContentLength = $PostStr.Length
$webRequest.ServicePoint.Expect100Continue = $false
#$webRequest.Credentials = New-Object System.Net.NetworkCredential -ArgumentList $username, $password 
#$webRequest.PreAuthenticate = $true
$webRequest.Method = "POST"
try
{
$requestStream = $webRequest.GetRequestStream()
}
catch
{
write-host $_.Exception 
}
$requestStream.Write($PostStr, 0,$PostStr.length)
$requestStream.Close()
[System.Net.WebResponse]$resp = $webRequest.GetResponse();
$rs = $resp.GetResponseStream();
[System.IO.StreamReader]$sr = New-Object System.IO.StreamReader -argumentList $rs;
[string]$results = $sr.ReadToEnd();
return $results;
}
Execute-HTTPPostCommand $url
[System.GC]::Collect()
