AWS Cloudformation CLI在将参数作为json文件传递时使用简写语法

问题描述 投票：1回答：1

我试图运行以下命令：

aws cloudformation update-stack --stack-name $stack.Trim('"') --use-previous-template --parameters file://./parameters.json

这是parameters.json的内容（您可以复制并粘贴here以检查它是否是有效的JSON字符串）：

[{"ParameterKey":"directoryName","UsePreviousValue":true},{"ParameterKey":"CodeDeployServiceRole","UsePreviousValue":true},{"ParameterKey":"ApplicationType","UsePreviousValue":true},{"ParameterKey":"EnvironmentCode","UsePreviousValue":true},{"ParameterKey":"InstanceRoleInstanceProfile","UsePreviousValue":true},{"ParameterKey":"VPCID","UsePreviousValue":true},{"ParameterKey":"SecurityGroupList","UsePreviousValue":true},{"ParameterKey":"KeyName","UsePreviousValue":true},{"ParameterKey":"Subnets","UsePreviousValue":true},{"ParameterKey":"dnsIpAddresses","UsePreviousValue":true},{"ParameterKey":"directoryId","UsePreviousValue":true},{"ParameterKey":"directoryBIOS","UsePreviousValue":true},{"ParameterKey":"ScalingTermination","UsePreviousValue":true},{"ParameterKey":"EC2ScaleUpCooldown","UsePreviousValue":true},{"ParameterKey":"AttributeDelayTimeout","UsePreviousValue":true},{"ParameterKey":"CwLowOperator","UsePreviousValue":true},{"ParameterKey":"EBSOptimized","UsePreviousValue":true},{"ParameterKey":"PatchingGroupTag","UsePreviousValue":true},{"ParameterKey":"CwHighOperator","UsePreviousValue":true},{"ParameterKey":"SSMInventoryTag","UsePreviousValue":true},{"ParameterKey":"CwHighEvaluations","UsePreviousValue":true},{"ParameterKey":"EC2ScaleUpAdjustment","UsePreviousValue":true},{"ParameterKey":"CwScalingMetric","UsePreviousValue":true},{"ParameterKey":"HealthyThresholdCount","UsePreviousValue":true},{"ParameterKey":"ImageId","ParameterValue":"ami-0b2e03736f1241bbb"},{"ParameterKey":"CodeDeployServiceRole","UsePreviousValue":true},{"ParameterKey":"directoryName","UsePreviousValue":true},{"ParameterKey":"HealthCheckIntervalSeconds","UsePreviousValue":true},{"ParameterKey":"ReleaseId","UsePreviousValue":true},{"ParameterKey":"UnhealthyThresholdCount","UsePreviousValue":true},{"ParameterKey":"EC2ScaleDownAdjustment","UsePreviousValue":true},{"ParameterKey":"ApplicationType","UsePreviousValue":true},{"ParameterKey":"EnvironmentCode","UsePreviousValue":true},{"ParameterKey":"Environment","UsePreviousValue":true},{"ParameterKey":"EbsVolumeType","UsePreviousValue":true},{"ParameterKey":"BackupsEnabled","UsePreviousValue":true},{"ParameterKey":"CwLowPeriod","UsePreviousValue":true},{"ParameterKey":"HealthCheckType","UsePreviousValue":true},{"ParameterKey":"InstanceRoleInstanceProfile","UsePreviousValue":true},{"ParameterKey":"ServiceLevel","UsePreviousValue":true},{"ParameterKey":"TerminatedInstances","UsePreviousValue":true},{"ParameterKey":"VPCID","UsePreviousValue":true},{"ParameterKey":"HealthCheckPath","UsePreviousValue":true},{"ParameterKey":"CwHighPeriod","UsePreviousValue":true},{"ParameterKey":"HealthCheckGracePeriod","UsePreviousValue":true},{"ParameterKey":"HealthCheckTimeoutSeconds","UsePreviousValue":true},{"ParameterKey":"CustomCWConfig","UsePreviousValue":true},{"ParameterKey":"ScalingMin","UsePreviousValue":true},{"ParameterKey":"SecurityGroupList","UsePreviousValue":true},{"ParameterKey":"CwLowEvaluations","UsePreviousValue":true},{"ParameterKey":"directoryBIOS","UsePreviousValue":true},{"ParameterKey":"CustomSSMStepCount","UsePreviousValue":true},{"ParameterKey":"ScalingMax","UsePreviousValue":true},{"ParameterKey":"InstanceType","UsePreviousValue":true},{"ParameterKey":"EncryptEBSVolume","UsePreviousValue":true},{"ParameterKey":"SSMRefreshFrequency","UsePreviousValue":true},{"ParameterKey":"CwHighThreshold","UsePreviousValue":true},{"ParameterKey":"CustomSSMSteps","UsePreviousValue":true},{"ParameterKey":"MinInstancesInService","UsePreviousValue":true},{"ParameterKey":"MatcherCode","UsePreviousValue":true},{"ParameterKey":"EbsVolumeSize","UsePreviousValue":true},{"ParameterKey":"EC2ScaleDownCooldown","UsePreviousValue":true},{"ParameterKey":"Iops","UsePreviousValue":true},{"ParameterKey":"KeyName","UsePreviousValue":true},{"ParameterKey":"Subnets","UsePreviousValue":true},{"ParameterKey":"dnsIpAddresses","UsePreviousValue":true},{"ParameterKey":"CWLogRetention","UsePreviousValue":true},{"ParameterKey":"EnableRackspaceTicket","UsePreviousValue":true},{"ParameterKey":"CwLowThreshold","UsePreviousValue":true},{"ParameterKey":"directoryId","UsePreviousValue":true},{"ParameterKey":"ScalingNotificationTopic","UsePreviousValue":true},{"ParameterKey":"LoadBalancerFullName","UsePreviousValue":true}]

我运行命令时得到这个：

我使用--debug运行命令并注意到它尝试使用简写语法解析参数：

2019-04-15 14:11:36,069 - MainThread - botocore.hooks - DEBUG - Event process-cli-arg.cloudformation.update-stack: calling handler <awscli.argprocess.ParamShorthandParser object at 0x0000020212160F28>
2019-04-15 14:11:36,070 - MainThread - awscli.argprocess - DEBUG - Parsing param --parameters as shorthand

我找不到任何方法强制CLI使用JSON语法而不是速记来解析参数。从docs看起来它应该自动完成。

任何想法为什么它试图使用速记语法？

看起来问题是parameters.json的编码。我认为由于文件的编码，CLI无法解析parameters.json，因此尝试使用简写语法而不是JSON语法来解析参数。

我使用以下代码创建了该文件：

$parameters = "{""ParameterKey"":""directoryName"",""UsePreviousValue"":true},{""ParameterKey"":""CodeDeployServiceRole"",""UsePreviousValue"":true},{""ParameterKey"":""ApplicationType"",""UsePreviousValue"":true},{""ParameterKey"":""EnvironmentCode"",""UsePreviousValue"":true},{""ParameterKey"":""InstanceRoleInstanceProfile"",""UsePreviousValue"":true},{""ParameterKey"":""VPCID"",""UsePreviousValue"":true},{""ParameterKey"":""SecurityGroupList"",""UsePreviousValue"":true},{""ParameterKey"":""KeyName"",""UsePreviousValue"":true},{""ParameterKey"":""Subnets"",""UsePreviousValue"":true},{""ParameterKey"":""dnsIpAddresses"",""UsePreviousValue"":true},{""ParameterKey"":""directoryId"",""UsePreviousValue"":true},{""ParameterKey"":""directoryBIOS"",""UsePreviousValue"":true},"

    # generate json file with parameters for stack
    foreach ($parameter in $stackJson.Stacks.Parameters){
        $parameterKey = $parameter.ParameterKey
        if ($parameterKey -eq "ImageId"){
            $parameters += "{""ParameterKey"":""$parameterKey"",""ParameterValue"":""$latestAmiId""},"
        }
        else {
            $parameters += "{""ParameterKey"":""$parameterKey"",""UsePreviousValue"":true},"            
        }        
    }

    $parameters = $parameters.TrimEnd(',')
    $parameters = "[" + $parameters + "]"
    #$parameters = ConvertFrom-Json $parameters
    $parameters | Out-File .\parameters.json

将-Encoding ascii添加到Out-File命令解决了该问题。
