Question

我正在尝试参数化PowerShell脚本。唯一的问题是，由于某种原因，当我用$ url的-uri调用invoke-restmethod时，它似乎很窒息。事实上，无论我在哪里尝试使用它，都会让人感到窒息。我相信我可能会错误地尝试这样做。是否有更好或更直接的方法来完成此脚本的参数化。

 #Variables that will probably need to change depeneding on environment
$server = "c3po:140"
$applicationName = "/webiznet_dev"
$applicationPath = "webiz_serviceapi"
$protocol = "http:"

#Variables that probably won't need to change
$userName = "PowerShellUser"
$auth = "token "
$rootUrl = '{0}//{1}{2}' -f $protocol, $server, $applicationName
$userId = 0

#Decrypting PWord 
#Might need to change $PSScriptRoot to where you have the txt file 
$securePassword = Get-Content "$PSScriptRoot\password.txt" | ConvertTo-SecureString
$BSTR = [System.Runtime.InteropServices.Marshal]::SecureStringToBSTR($securePassword)
$password = [System.Runtime.InteropServices.Marshal]::PtrToStringAuto($BSTR)
$login = @{"Username"=$userName; "Password"=$password; }

#Login and Get Token 
$fullApplicationPath = "{0}//{1}/{2}" -f $protocol, $server, $applicationPath
$url = "{0}/job/login" -f $fullApplicationPath
$jsonHeaders = "{'UserId':$userId,'ApplicationName':$applicationName,'RootUrl':$rootUrl,'ApplicationInsightsGUID':'8773f299-9fed-4431-ab34-888888888888','DisableEmail':'true'}";
$HeaderWrap = @{"Authorization"=$auth};
$HeaderWrap.Add("x-webiz-app-info",$jsonHeaders);
$token = Invoke-RestMethod -Uri $url -Method Post -Body $login -Headers $HeaderWrap;


#Write out url which works fine
 Write-Host $url

#Load values for api calls as the token is now populated so the appInfo can get properly populated
$encryptedString = $token.EncryptedString
$userId = $token.UserId
$auth = "token $encryptedString"
$jsonHeaders = "{'UserId':$userId,'ApplicationName':$applicationName,'RootUrl':$rootUrl,'ApplicationInsightsGUID':'8773f299-9fed-4431-ab34-888888888888','DisableEmail':'true'}";
$HeaderWrap = @{"Authorization"=$auth};
$HeaderWrap.Add("x-webiz-app-info",$jsonHeaders);

#Scripts to call scheduled notification jobs in 
$url = '{0}/Job/RunNotificationReminders' -f $fullApplicationPath
Invoke-RestMethod  $url -Method Post -Headers $HeaderWrap
$url = '{0}/Job/RunAddressChanges' -f $fullApplicationPath
Invoke-RestMethod $url -Method Post -Headers $HeaderWrap;
$url = '{0}/Job/RunStorageUnitTemperatureReadingDueAlerts' -f $fullApplicationPath
Invoke-RestMethod $url -Method Post -Headers $HeaderWrap;
$url = '{0}/Job/RunThermometerCalibrationDueAlerts' -f $fullApplicationPath
Invoke-RestMethod $url -Method Post -Headers $HeaderWrap;

您是否尝试将JSON值包装在单个qoutes和键中？

例如 - 在构建$ jsonHeader时在$ applicationname和$ rooturl周围放置单引号？

示例

$ jsonHeaders =“{'UserId'：$ userId，'ApplicationName'：'$ applicationName'，'RootUrl'：'$ rootUrl'，'ApplicationInsightsGUID'：'8773f299-9fed-4431-ab34-888888888888'，' DisableEmail '：' 真'}“;

<强>原因

我这样说是因为您的错误表明Web服务正在接收'w'而不是ApplicationName的另一个预期值。在查看原始代码为JSON标头生成的值时，您可以清楚地看到/ w是字符串中的第一个未加引号的字符（来自/ webiznet_dev），并且很可能会破坏您的Web服务。
{{ '用户ID'：，的 '应用程序名'：/ webiznet_dev 下， '使用rootUrl'：http://c3po:140/webiznet_dev， 'ApplicationInsightsGUID'：'8773f299-9fed- 4431-ab34-888888888888'，'DisableEmail'：'true'}，令牌}
