几乎掌握了使用 Powershell Invoke-WebRequest 我现在开始尝试控制异常错误

在第一段代码中，我必须处理从 Web 服务返回的异常。您可以看到 400 代码与消息描述和详细消息一起返回。

Try {
    $what = Invoke-WebRequest -Uri $GOODURL -Method Post -Body $RequestBody -ContentType $ContentType
}

catch [System.Net.WebException] {
    $Request = $_.Exception
    Write-host "Exception caught: $Request"

    $crap = ($_.Exception.Response.StatusCode.value__ ).ToString().Trim();
    Write-Output $crap;
    $crapMessage = ($_.Exception.Message).ToString().Trim();
    Write-Output $crapMessage;
    $crapdescription = ($_.ErrorDetails.Message).ToString().Trim();
    Write-Output $crapdescription;
 }

输出返回。好的！
