Question

我正在尝试生成一个包含（IF，Else）语句的powershell脚本。主要是由于不同版本如何调用Web请求的兼容性问题。

V < 2.0 : Uses [System.Net.WebRequest] for HTTP Requests

＆安培;

V > 2.0 : Uses Invoke-WebRequest

这是我的代码：

$pcName="$ENV:COMPUTERNAME";
$psVers=$host.Version.Major;

if ($psVers -le 2) 

            {$request = [System.Net.WebRequest]::Create('http://xxx.co.kr'); 
             $request.Method = "POST"; $request.ContentType = "application/x-www-form-urlencoded"; 
             $bytes = [System.Text.Encoding]::ASCII.GetBytes("pcName=$pcName"); 
             $request.ContentLength = $bytes.Length; $requestStream = $request.GetRequestStream(); 
             $requestStream.Write( $bytes, 0, $bytes.Length ); $requestStream.Close(); 
             $request.GetResponse();}

Else  
            {$POSTdata = @{pcName=$pcName} 
             Invoke-WebRequest -Uri http://xxx.co.kr -Method POST -Body $POSTdata};

以下是我从Powershell v-2.0收到的错误：

The term 'Else' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelli
ng of the name, or if a path was included, verify that the path is correct and try again.
At line:1 char:5
+ Else <<<<
    + CategoryInfo          : ObjectNotFound: (Else:String) [], CommandNotFoundException
    + FullyQualifiedErrorId : CommandNotFoundException

删除Else关键字上方的空行：

$pcName="$ENV:COMPUTERNAME";
$psVers=$host.Version.Major;

if ($psVers -le 2) 

            {$request = [System.Net.WebRequest]::Create('http://xxx.co.kr'); 
             $request.Method = "POST"; $request.ContentType = "application/x-www-form-urlencoded"; 
             $bytes = [System.Text.Encoding]::ASCII.GetBytes("pcName=$pcName"); 
             $request.ContentLength = $bytes.Length; $requestStream = $request.GetRequestStream(); 
             $requestStream.Write( $bytes, 0, $bytes.Length ); $requestStream.Close(); 
             $request.GetResponse();}
Else  
            {$POSTdata = @{pcName=$pcName} 
             Invoke-WebRequest -Uri http://xxx.co.kr -Method POST -Body $POSTdata};

Powershell 2.0 - 条件（Else）未被识别为cmdlet函数的名称
