Question

我正在构建一个powershell脚本来在类似REST的服务器上执行命令，我正在使用powershell将XML数据发送到Web服务。除非“应用程序”产生错误，否则一切都工作正常。该应用程序回复xml中的详细信息，并给我一个Web请求错误（在这种情况下为400），这是我遇到问题。每当我得到一个不是200的Web请求错误时，命令就会抛出一个错误，这会搞砸我处理错误的方式。

这是我接收的响应示例（使用fiddler）：

HTTP/1.1 400 Bad Request
Date: Thu, 29 Nov 2012 04:29:48 GMT
Content-Type: text/xml;charset=ISO-8859-1
Connection: close

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Status>
    <operation>Add Network</operation>
    <result>ERROR</result>
    <resultCode>REASON_210</resultCode>
</Status>

这是我在powershell中收到的错误：

Exception calling "UploadData" with "3" argument(s): "The remote server returned an error: (400) Bad Request."
At C:\Scripting\test.ps1:47 char:34
+     $response = $query.UploadData <<<< ($url,"POST",$byteArray)
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

Exception calling "GetString" with "1" argument(s): "Array cannot be null.
Parameter name: bytes"
At C:\Scripting\test.ps1:48 char:62
+     $stringresponse = [System.Text.Encoding]::ASCII.GetString <<<< ($response)
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : DotNetMethodException

我进一步挖掘了错误，这就像我可以检索响应内容（XML）一样接近。

我以为我可能会把它拉出来......

$error[1].exception.InnerException.Data

但它是空的：（

PS C:\Scripting> $error[1].exception.InnerException | fl -force

IsFromCache             : False

这是我正在使用的powershell代码：

function send_web ($url,$data) {
    [System.Net.ServicePointManager]::ServerCertificateValidationCallback = {$true}
    $query = new-object system.net.WebClient
    $auth = 'Basic ' + [System.Convert]::ToBase64String([System.Text.Encoding]::UTF8.GetBytes($username+":"+$password ))
    $query.Headers.Add('Authorization', $auth )
    [byte[]]$byteArray = [System.Text.Encoding]::ASCII.GetBytes($data) 
    $query.Headers.Add("ContentType","application/xml")
    $response = $query.UploadData($url,"POST",$byteArray)
    $stringresponse = [System.Text.Encoding]::ASCII.GetString($response)
    return $stringresponse
}

这似乎不应该是一件很难的事情，任何帮助都会非常感激：）
