解决Terraform local-exec命令的换行解析错误

原代码执行时触发的错误：

Error: Missing newline after argument
on main.tf line 9, in resource "null_resource" "enable-usage-plan":
9: command = "aws apigateway update-usage-plan --usage-plan-id sx8lzu --patch-operations op="add",path="/apiStages",value="7tdnnlppg1:poc""
An argument definition must end with a newline.

该命令在AWS CLI中可正常运行，问题源于HCL解析器对单行转义字符串的处理歧义，可通过以下两种方式修改：

方案一：使用Heredoc多行字符串格式

无需转义引号，命令结构更清晰，同时满足Terraform对参数换行的要求：

resource "null_resource" "enable-usage-plan" {
  triggers = {
    usage_plan_id = "cd8lab"
  }

  provisioner "local-exec" {
    command = <<EOF
aws apigateway update-usage-plan --usage-plan-id cd8lab --patch-operations op="add",path="/apiStages",value="7tdnnlppg1:poc"
EOF
  }
}

方案二：使用单引号包裹命令

用单引号包裹整个命令字符串，避免内部双引号的转义需求，让HCL解析器正确识别完整参数：

resource "null_resource" "enable-usage-plan" {
  triggers = {
    usage_plan_id = "cd8lab"
  }

  provisioner "local-exec" {
    command = 'aws apigateway update-usage-plan --usage-plan-id cd8lab --patch-operations op="add",path="/apiStages",value="7tdnnlppg1:poc"'
  }
}
