将 SOAP 请求放入此处的字符串中答案

【问题标题】：Putting a SOAP request in a here-string将 SOAP 请求放入此处的字符串中
【发布时间】：2013-03-24 02:59:48
【问题描述】：

我正在尝试编写一个脚本，该脚本将发送随机 SOAP 请求以测试另一个进程。但是我似乎无法创建变量。每次我将代码从记事本复制/粘贴到 PS 控制台时，脚本都会以 >> 结尾（即使在多次按 Enter 后也是如此）。即使我只复制/粘贴脚本的$SOAPRequest 部分，也会发生同样的事情。如果我注释掉整个 here-string，脚本就会运行（尽管由于缺少 SOAP 内容而出现错误）。

我尝试了以下各种组合：

用反斜杠转义英镑符号
删除包含井号的行
在 Powershell v1 和 Powershell v2 中使用 SOAP 请求创建变量
删除所有带有 http 地址的行
使用@''@（不仅没用还需要变量扩展）

问题：如何让 Powershell 将 here-string 中的内容设置为 $SOAPRequest 变量？换句话说，我怎样才能停止>>？通常这意味着我错过了括号、括号或双引号，但我似乎找不到类似的东西。我不知道为什么这不起作用。

我寻求帮助的页面：

$SOAPRequest 变量：

$SOAPRequest = [xml] @"
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:soa="http://bmc.com/ao/xsd/2008/09/soa">

尽管这个问题似乎与这里的字符串特别相关，但这是上下文脚本的其余部分：

【解决方案1】：

此处字符串中的终止“@”必须从第 1 列开始。

当您将它粘贴到代码中时，它会出现，它被缩进，并且缩进中的前导空格导致解析器继续读取以下代码作为 here-string 的一部分。由于字符串从未正确终止，>> 提示输入此处字符串的更多数据，或终止的 "@.

编辑：如果您不想弄乱 Process 块中的缩进，您可以将可扩展的 here-string 作为脚本块移动到 Begin 块中，稍后再调用它：

Begin{
$SoapString = {
@"
This is my here-string containing $variable
"@
}
}


Process{
$variable = "MY VARIABLE"

  foreach ($x in 1)
   {
     &$SoapString
    }
}


This is my here-string containing MY VARIABLE

如果你不喜欢它在脚本的头部混乱，如果你愿意，你可以把 Being 块放在底部。 Powershell 仍然会按照 Begin、Process、End 的顺序运行它们，无论它们在脚本中的顺序是什么：

Process{
$variable = "MY VARIABLE"

  foreach ($x in 1)
   {
     &$SoapString
   }
}

Begin{
$SoapString = {
@"
This is my here-string containing $variable
"@
}
}

This is my here-string containing MY VARIABLE

太好了，我没有意识到这里字符串的打开和关闭必须从第 1 列开始。谢谢！
开头不必，但结尾必须。
