Powershell 中的字符串构建问题

Question

我正在尝试参数化一个 powershell 脚本。唯一的问题是，由于某种原因，当我使用 $url 的 -uri 调用 invoke-restmethod 时，它似乎令人窒息。事实上，无论我在哪里尝试使用它，它都令人窒息。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;

收到的错误之一

Answer 1

您是否尝试将 JSON 值包装在单个 qoutes 以及键中？

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':'true'}";

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。查看原始代码为 JSON 标头生成的值，您可以清楚地看到 /w 是字符串中第一个不带引号的字符（来自 /webiznet_dev），并且很可能会破坏您的网络服务。
{{'UserId':,'ApplicationName':/webiznet_dev,'RootUrl':http://c3po:140/webiznet_dev,'ApplicationInsightsGUID':'8773f299-9fed- 4431-ab34-888888888888','DisableEmail':'true'}, 令牌}
