如何在 Azure 逻辑应用程序中获取 json http 响应的值答案

【问题标题】：how to get a value of a json http response in azure logic app如何在 Azure 逻辑应用程序中获取 json http 响应的值

【问题描述】：

我试图通过解析下面的输出样本将“id”值设置为变量。 REST API 调用将返回多个值，如下所示，我感兴趣的是仅通过参数值或通过初始化一个变量。如何在 Azure 逻辑应用程序中进行此值提取？

非常感谢任何帮助。

[
  {
    \"id\": 1,
    \"name\": \"xyz-List\",
    \"data\": {
      \"urls\": [
        \"*.test1.com\",
        \"*.test2.com\"
      ],
      \"type\": \"exact\"
    },
    \"modify_by\": \"admin@xyz.com\",
    \"modify_time\": \"2022-06-29T21:05:27.000Z\",
    \"modify_type\": \"Created\",
    \"pending\": 0
  },
  {
    \"id\": 2,
    \"name\": \"abc-List\",
    \"data\": {
      \"urls\": [
        \"www.mytesting.com\"
      ],
      \"type\": \"exact\"
    },
    \"modify_by\": \"admin@xyz.com\",
    \"modify_time\": \"2022-06-29T21:05:27.000Z\",
    \"modify_type\": \"Created\",
    \"pending\": 0
  },
  {
    \"id\": 3,
    \"name\": \"azure-list\",
    \"data\": {
      \"type\": \"exact\",
      \"urls\": [
        \"www.xyz.com\",
        \"www.azure-test.com\"
      ],
      \"json_version\": 2
    },
    \"modify_by\": \"admin@xyz.com\",
    \"modify_time\": \"2022-09-26T01:25:20.000Z\",
    \"modify_type\": \"Edited\",
    \"pending\": 0
  }
]

这在此处和 Microsoft 网站上都有详细记录。

【解决方案1】：

为了遍历 JSON，我使用了 for-each 循环并使用以下表达式提取了 Id 并将其值设置为变量。

@items('For_each')['id']

结果：

要在您的逻辑应用程序中重现相同内容，您可以使用以下对我有用的代码视图。
