PowerShell-V5 Invoke-Webrequest 添加 2 个标头授权标头并接受接受标头 [英] PowerShell-V5 Invoke-Webrequest adding 2 headers authorization header and accept accept header
问题描述
我正在尝试创建一个脚本，该脚本将使用 powershell 和 invoke-webrequest 自动升级 NSX，以利用 NSX Manager 的 API 调用.我已经完成了脚本，但脚本的某些部分我需要检查和匹配响应中的某些数据.事实上，NSX API 响应将 90% 是 xml 格式，但有时它可以是 json.如果响应是 json 格式，我的匹配将不起作用，并且脚本的某些部分也将不起作用，因为它期望 xml 并且无法将 json 转换为 xml.
I am trying create a script that will automate the upgrade of NSX using powershell and invoke-webrequest to utilize the API calls of the NSX Manager. I am doen with the script but some part of the script i need to check and match on some data in the respond. as a matter of fact the NSX API response will 90% be in xml format but some times it can be in json. If the response came in json format my matching will not work and also some parts of the script will not work as it is expecting xml and can not convert json to xml.
据我所知，从 powershell v4 开始，您可以添加接受标头，但问题是我已经在使用一个标头进行授权.
as i understand that starting from powershell v4 you can add the accept header but the problem is that i am already using one header for authorization.
是否可以在 powershell 的 invoke-webrequest 中添加多个标头，如果是，会怎样.
Is it possible to add multiple headers in the invoke-webrequest in powershell and if yes how would it be.
下面是我将检查已部署 NSX 的当前版本的脚本的一部分.所以它将匹配响应中的一个值，该值将显示版本.
Below is a part of the script that i have which will check the current version of the deployed NSX. so it will match on a value in the response which will show the version.
#Variables to be used within the script.
[CmdletBinding()]
$NSXUsername = "admin"
$NSXPassword = "VMware1!"
$uriP = "https://HQ-NSX-01a.nsx.gss"
# Start time.
$startclock = (Get-Date)
Write-Host -BackgroundColor:Black -ForegroundColor:Green "Hello"
Write-Host -BackgroundColor:Black -ForegroundColor:Green "This script will help you to automate a full NSX environment deployment"
Write-Host -BackgroundColor:Black -ForegroundColor:Green "FULL NSX Tier Deployment for Single-VC is starting, This Deployment proccess will take an average of 60 min

# Create NSX authorization string and store in $head and used in API Calls

exit
}
Write-Host -BackgroundColor:Black -ForegroundColor:Green " Current version of NSX deployed and to be upgraded is $nsxcv
"
如果是xml格式的响应如下，我会匹配版本.
The response if it is in xml format would as below and i will match on the version.
<?xml version="1.0" encoding="UTF-8"?>
<globalInfo>
<currentLoggedInUser>admin</currentLoggedInUser>
<versionInfo>
<majorVersion>6</majorVersion>
<minorVersion>1</minorVersion>
<patchVersion>5</patchVersion>
<buildNumber>3102213</buildNumber> <<<--- this is my match
</versionInfo>
</globalInfo>
如果响应是 xml 格式(90% 的时间)，上面的脚本就可以正常工作，但如果是 json，我将收到以下错误，脚本将退出.
The above script will just work fine if the response is in xml format (which 90% of the time) but if it is json i will get the below error and the script will exit.
Cannot convert value "{"currentLoggedInUser":"admin","versionInfo":{"majorVersion":"6","minorVersion":"1","patchVersion":"5","buildNumber":"3102213"}}"
to type "System.Xml.XmlDocument". Error: "The specified node cannot be inserted as the valid child of this node, because the specified node is the wrong
type."

非常感谢您的帮助.
谢谢.
推荐答案
我了解到您打算通过 powershell 向 REST API 调用添加多个标头.而不是像这样添加标题，
I gather that you intend to add multiple headers to a REST API call through powershell. Instead of adding headers like this,
$head = @{"Authorization"="Basic $auth"}
Invoke-WebRequest -Uri "$uriP/api/1.0/appliance-management/global/info" -Method:Get -Headers $head -ContentType "application/xml" -ErrorAction:Stop -TimeoutSec 60
你可以像这样添加它们
Invoke-WebRequest -Uri "$uriP/api/1.0/appliance-management/global/info" -Method:Get -Headers @{"Authorization"="Basic $auth"; "Accept"="application/xml"} -ContentType "application/xml" -ErrorAction:Stop -TimeoutSec 60
