Question

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，脚本都以＆gt;＆gt;结尾。（即使多次击中后也是如此）。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内容而导致错误）。

我尝试了以下各种组合：

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

问题：如何让Powershell将here-string中的内容设置为$SOAPRequest变量？换句话说，我怎么能停止＆gt;＆gt;？通常这意味着我错过了括号，括号或双引号，但我似乎找不到那样的东西。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] @"

尽管此问题似乎与here-string具体相关，但这是上下文脚本的其余部分：

此处字符串中的@终止必须从第1列开始。

当您将其粘贴到代码中时，它会缩进，并且来自缩进的前导空格会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，因此＆gt;＆gt;提示输入here-string或终止“@。

的更多数据

编辑：如果你不想弄乱进程块中的缩进，你可以将一个可扩展的here-string作为一个脚本块移动到Begin块中，然后再调用它：

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

如果你不喜欢它会破坏脚本的头部，你可以根据需要将Being块放在底部。 Powershell仍会按照Begin，Process，End的顺序运行它们，无论它们在脚本中的顺序如何：

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

将SOAP请求放在here-string中
