Powershell ErrorSessionTokenFilter:通过HTTP标头提供的令牌与服务器生成的令牌不匹配

我试图使用Viptela的API接口从中提取事件信息。我设法获得了警报和令牌信息，但当我试图提取事件信息时，它给了我一个HTML登录页面，而不是带有事件信息的JSON

我知道，在访问事件API链接之前，我应该拥有调用事件API URL的令牌。我不确定我错过了哪一步，这对我来说不起作用。有人能指出下面代码中缺失的部分来纠正问题吗

    if (-not ([System.Management.Automation.PSTypeName]'TrustAllCertsPolicy').Type) {
    Add-Type -TypeDefinition @"
        using System.Net;
        using System.Security.Cryptography.X509Certificates;
        public class TrustAllCertsPolicy : ICertificatePolicy {
            public bool CheckValidationResult(
                ServicePoint srvPoint, X509Certificate certificate,
                WebRequest request, int certificateProblem) {
                return true;
            }
        }
"@
}
[System.Net.ServicePointManager]::CertificatePolicy = New-Object TrustAllCertsPolicy -ErrorAction SilentlyContinue
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

$Authorization = [Convert]::ToBase64String(
    [Text.Encoding]::ASCII.GetBytes(
        (
            "{0}:{1}" -f ('UserName' , 'Password')
        )
    )
)

$Headers = @{"authorization" = "Basic "+$Authorization}


$Uri = "https://vmanage.viptela.net:443/dataservice/client/token"
$gettoken = Invoke-RestMethod -Method Get -Uri $Uri -Headers $Headers -SessionVariable websession
$gettoken.Cookies
$cookie = ($websession.Cookies.GetCookies($Uri)).Value

$body = '{
    "query": {
        "condition": "AND",
        "rules": [
            {
                "value": [
                    "1"
                ],
                "field": "entry_time",
                "type": "date",
                "operator": "last_n_hours"
            }
        ]
    }
}'

$Headersnew = New-Object "System.Collections.Generic.Dictionary[[String],[String]]"
$Headersnew.Add("X-XSRF-TOKEN", $gettoken)
$Headersnew.Add("Authorization", "Basic "+$Authorization)
$Headersnew.Add("Content-Type", "application/json")
$Headersnew.Add("Cookie", "JSESSIONID="+$cookie)


$geteventurl = "https://vmanage.viptela.net:443/dataservice/event"

$getevent = Invoke-RestMethod -Method POST -Uri $geteventurl -body $body -Headers $Headersnew 
$getevent

我得到的结果如下，我通过邮递员尝试了同样的方法，效果很好

Invoke-RestMethod : ErrorSessionTokenFilter: Token provided via HTTP Header does not match the token generated by the server.
At C:\Users\user\Desktop\00viptela\GetEvents.ps1:58 char:13

    + FullyQualifiedErrorId : WebCmdletWebResponseException,Microsoft.PowerShell.Commands.InvokeRestMethodCommand

请帮忙

问候,，

纳雷什找到了答案，这可能会帮助有类似问题的人

在第一个请求中，添加一个-SessionVariable参数并给它一个字符串 （没有前面$的任何字符串）然后在第二个请求中传递该字符串 （这次使用前面的$）添加到-WebSession参数

将-websession参数添加到第二个调用之后，它就工作了。（-WebSession$WebSession）

希望它能帮助别人

通过邮递员，当我使用Powershell时，它会抛出一个错误。Invoke RestMethod:ErrorSessionTokenFilter:通过HTTP标头提供的令牌与服务器生成的令牌不匹配。

Invoke-RestMethod -Method POST -Uri $geteventurl -body $body -Headers $Headersnew -WebSession $websession
