“calls”属性无效 - 值“”不在允许的值范围内

Question

我想添加一个条件，仅当给出时才允许我添加自定义速率限制（

local.limit == true

），否则不要将其添加到政策中。当提供速率限制时，它工作正常，但如果没有速率限制，则会出现错误

“calls”属性无效 - 值“”不在允许范围内 值范围。

根据 https://learn.microsoft.com/en-us/azure/api-management/rate-limit-policy 调用是必填字段。

variable "rate_limit" {
  type = string
}

locals {
  j       = "context.Request.Headers.GetValueOrDefault(\"Authorization\", \"\").AsJwt()?.Subject"
  s       = "context.Subscription.Id"
  limit   = var.rate_limit != ""
}
<choose>
          <when condition="@((${local.j} != null || ${local.s} != null) && (${local.limit == true}))">
               <rate-limit-by-key calls="${var.rate_limit}" renewal-period="60" counter-key="@(${local.j} ?? ${local.s})" />
          </when>
          <when condition="@(context.Request.Headers.GetValueOrDefault("ApiKey") == "Default")">
               <rate-limit-by-key calls="100" renewal-period="60" counter-key="@(context.Request.IpAddress)" />
          </when>
</choose>

计划看起来像这样

<when condition="@((context.Request.Headers.GetValueOrDefault("Authorization", "").AsJwt()?.Subject != null || context.Subscription.Id != null) && (false))">
   <rate-limit-by-key calls="" renewal-period="60" counter-key="@(context.Request.Headers.GetValueOrDefault("Authorization", "").AsJwt()?.Subject ?? context.Subscription.Id)" />
</when>

我成功修复了它

locals {
  j         = "context.Request.Headers.GetValueOrDefault(\"Authorization\", \"\").AsJwt()?.Subject"
  s   = "context.Subscription.Id"
  limit             = var.rate_limit != ""
  rate_limit_config = <<XML
  <when condition="@(${local.j} != null || ${local.s} != null && ${local.limit})">
                <rate-limit-by-key calls="${var.rate_limit}" renewal-period="60" counter-key="@(${local.j} ?? ${local.s})" />
          </when>
  XML
}


<choose>
        ${var.api.rate_limit != "" ? local.rate_limit_config : var.api.rate_limit}
          <when condition="@(context.Request.Headers.GetValueOrDefault("ApiKey") == "Default")">
      <rate-limit-by-key calls="10" renewal-period="1" counter-key="@(context.Request.IpAddress)" />
          </when>
