逻辑应用程序 - 迭代来自 HTTP 调用的 JSON 输出答案

【问题标题】：Logic Apps - Iterate over JSON output from HTTP call逻辑应用程序 - 迭代来自 HTTP 调用的 JSON 输出
【发布时间】：2018-06-13 16:33:24
【问题描述】：
我们正在使用 Azure 逻辑应用 HTTP 连接器根据上一步中另一个 REST 服务返回的输出调用 REST 服务。第一个服务返回一个 JSON 数组输出，如下所示。要求是遍历服务 1 的 JSON 输出，并根据服务 1 输出构造服务 2 的 URL。我们如何在 Logic 应用中实现这一点？

【问题讨论】：
标签： arrays json azure azure-logic-apps
【解决方案1】：
在 Service1 添加一个动作 parse json 并输入作为上一步的输出（service1），这将公开字段。然后使用这些字段构造url并在下一步循环中进行http调用将自动添加。
【讨论】：
使用 @body('Service1')['rercords'] 的输入创建 For_Each 循环。
然后在该循环中添加一个 http 操作并将 url 作为 @item('For_Each')['attributes']['url']
+1 用于向我展示“解析 JSON”。但在旁注中，现在隐藏在“操作”动作中。
