[英]PowerShell JSON Headers not Converting correctly
I am using an API REST call, but the problem is that it for some reason is not passing the header value correctly.我正在使用 API REST 调用,但问题是它由于某种原因没有正确传递标头值。 I am getting an error about it not converting from "System.String"
to "System.Collections.IDictionary"
.我收到关于它没有从"System.String"
转换为"System.Collections.IDictionary"
。 The code is:代码是:
$Headers = New-Object 'System.Collections.Generic.Dictionary[[String],[String]]'
$Headers.Add('X-CENTRIFY-NATIVE-CLIENT', 'true')
$Headers.Add('Content-Type', 'application/json')
$Body = @{
TenantId = 'ID'
User = 'cloudadmin@andrew1.com'
Version = '1.0'
}
#$wr = Invoke-WebRequest -Method Post -Uri $url -Headers $Headers -Body $Body -Verbose
Invoke-RestMethod -Uri "https://uri/Security/StartAuthentication" -Method Post -Headers ($Headers | ConvertTo-Json -Compress) -UseBasicParsing -Body $Body
But when I execute I get this error (FQID):但是当我执行我得到这个错误(FQID):
Invoke-RestMethod : Cannot bind parameter 'Headers'. Cannot convert the "{
"X-CENTRIFY-NATIVE-CLIENT": "true",
"Content-Type": "application/json"
}" value of type "System.String" to type "System.Collections.IDictionary".

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (:) [Invoke-RestMethod], ParameterBindingException

I have tried my headers being like this as well:我也试过我的标题是这样的:
$headers = @{
'Content-Type'= 'application/json'
'X-CENTRIFY-NATIVE-CLIENT'= 'true'
}
But I still get that same error.但我仍然遇到同样的错误。 It is odd that it keeps complaining about this reference;奇怪的是,它一直在抱怨这个引用; This library is not native to PoSH.这个库不是 PoSH 原生的。 Is there a DLL I should load or is there a better way to go about this?是否有我应该加载的 DLL 或者有更好的方法来解决这个问题?
The -Headers
parameter expects a dictionary, not a json object. -Headers
参数需要一个字典,而不是一个 json 对象。
Pass $Headers
directly:直接传递$Headers
:
$uri = "https://uri/Security/StartAuthentication"
Invoke-RestMethod -Uri $uri -Method Post -Headers $Headers -UseBasicParsing -Body $Body
You can inspect parameter details with Get-Help
:您可以使用Get-Help
检查参数详细信息:
PS > Get-Help Invoke-WebRequest -Parameter Headers
-Headers <IDictionary>
Required? false
Position? Named
Accept pipeline input? false
Parameter set name (All)
Aliases None
Dynamic? false
I took the json conversion out of the header on your invoke restmethod.我从你的调用 restmethod 的标题中取出了 json 转换。 That part will need to be done on your payload $Body
.这部分需要在您的有效负载$Body
。 Give this a try.试试这个。
$Headers = @{}
$Headers.Add('X-CENTRIFY-NATIVE-CLIENT', 'true')
$Headers.Add('Content-Type', 'application/json')
$Body = @{
TenantId = 'ID'
User = 'cloudadmin@andrew1.com'
Version = '1.0'
}
$Body = ($Body | ConvertTo-Json)
#$wr = Invoke-WebRequest -Method Post -Uri $url -Headers $Headers -Body $Body -Verbose
Invoke-RestMethod -Uri "https://uri/Security/StartAuthentication" -Method Post -Headers $Headers -UseBasicParsing -Body $Body
