如何使用 Azure CLI 筛选 JMESPath 中的元素数组

Question

我是 JMESPath 解析的新手。 az network lb inbound-nat-rule list --resource-group MYRG --lb-name MYLB 返回低于输出，我只想在响应中过滤 backendIpConfiguration.id 和 backendPort。

下面的响应包含元素数组。

[

      "applicationSecurityGroups": null,

JMESPath 中的过滤非常简单，filters and multiselect hashes 的文档非常简单明了。

在这里，一个简单的查询如下：

[].{backendIpConfigurationId: backendIpConfiguration.id, backendPort: backendPort}

会给你过滤后的 JSON:

[
  {
    "backendIpConfigurationId": "/subscriptions/XXXX/XXX/XXX/providers/Microsoft.Network/networkInterfaces/XXX/ipConfigurations/XXXX",
    "backendPort": 1367
  },
  {
    "backendIpConfigurationId": "/subscriptions/XXXX/XXX/XXX/providers/Microsoft.Network/networkInterfaces/XXX/ipConfigurations/XXXX",
    "backendPort": 3006
  }
]

只包含您要查找的信息。
