使用带有 Postman 的 Azure Rest API 更新逻辑应用重复频率答案

【问题标题】：Using Azure Rest API with Postman to Update Logic App Recurrence Frequency使用带有 Postman 的 Azure Rest API 更新逻辑应用重复频率
【发布时间】：2019-10-21 15:20:58
【问题描述】：

我们有一个逻辑应用，它每 30 分钟轮询一次服务总线以获取消息。我想使用 Postman 将轮询频率更新为 30 秒进行测试。

我可以使用 Azure API 获取与逻辑应用关联的工作流的详细信息，然后在该工作流中获取与轮询服务总线关联的触发器。这会返回 JSON 格式：

{
    "properties": {
        "provisioningState": "Succeeded",
        "createdTime": "2019-08-13T21:08:14.8768439Z",
        "changedTime": "2019-10-21T14:32:46.0204187Z",
        "state": "Enabled",
        "status": "Running",
        "lastExecutionTime": "2019-10-21T14:32:04.149971Z",
        "nextExecutionTime": "2019-10-21T14:32:46.285845Z",
        "recurrence": {
            "frequency": "Second",
            "interval": 30
        },
        "workflow": {
            "id": "/subscriptions/<subscription>/resourceGroups/<resource-group-name>/providers/Microsoft.Logic/workflows/<workflow-name>/versions/08586299385548076458",
            "name": "08586299385548076458",
            "type": "Microsoft.Logic/workflows/versions"
        }
    },
    "id": "/subscriptions/<subscription>/resourceGroups/<resource-group-name>/providers/Microsoft.Logic/workflows/<workflow-name>/triggers/When_a_message_is_received_in_a_topic_subscription_(auto-complete)",
    "name": "When_a_message_is_received_in_a_topic_subscription_(auto-complete)",
    "type": "Microsoft.Logic/workflows/triggers"
}

在上面的结构中，我想 PATCH "recurrence" : { "frequency": "Second" } to "recurrence" : { "frequency": "Minute" }

通过查看REST API documentation，我不清楚这是否可能？我看到 Trigger 有一个 setState 选项，其中一个属性是 RecurrenceFrequency 但如果我尝试使用它，我会返回以下错误：

{
    "error": {
        "code": "WorkflowTriggerSetStateNotSupported",
        "message": "The workflow trigger 'When_a_message_is_received_in_a_topic_subscription_(auto-complete)' of type 'ApiConnection' does not support the set state action."
    }
}

如果有人能告诉我这是否可能，我做错了什么或指出一个例子，我将不胜感激。

更新的答案和解决方法

不幸的是，尽管 API 文档表明这是可能的，但您不能使用 setState 更新任何类型的触发器，无论是原生的还是托管的，启用与否。

本机响应：

{"error":{"code":"WorkflowTriggerSetStateNotSupported","message":"The workflow trigger 'Recurrence' of type 'Recurrence' does not support the set state action."}}

托管响应：

{"error":{"code":"WorkflowTriggerSetStateNotSupported","message":"The workflow trigger 'sbAuto' of type 'ApiConnection' does not support the set state action."}}

您也不能使用 PATCH 动词来更新工作流：

{"error":{"code":"PatchWorkflowPropertiesNotSupported","message":"The request to patch workflow 'XXXXXXX' is not supported. None of the fields inside the properties object can be patched."}}

我已经向 Microsoft 提出了这个问题。

但是...

可能是使用 PUT 动词来更新工作流。

为了实现这一点，最好使用 GET 动词检索工作流，更新 JSON 重复对象，然后使用 PUT（创建或更新）重新发布。

下面的示例获取了我创建的工作流的定义tempotestla。

请求：

GET https://management.azure.com/subscriptions/651a2541-8d19-42a0-85fe-89a9eee81c48/resourceGroups/TechSouth/providers/Microsoft.Logic/workflows/tempotestla?api-version=2016-06-01 HTTP/1.1

这是我的工作流程概览页面：

从这里开始，如果您使用的是面向对象的代码或脚本，您可以反序列化响应正文并更改间隔：

objResponse.properties.definition.triggers.<TriggerType>.<TriggerName>.frequency = "Minute"

然后，重新序列化您的对象并在 PUT 请求中将其发送回 API。在这里，我将小时数更改为天数：

您应该在响应正文中获得更新的对象。

希望这会有所帮助。

【讨论】：

嗨，杰米，感谢您的回复。触发器是一个服务总线触发器 - 是否有一些文档可以告诉我它不能使用 SetState？我尝试使用您建议的格式更新触发器，但我仍然得到相同的响应“'ApiConnection' 不支持设置状态操作” - 我正在使用management.azure.com/subscriptions{{SubscriptionID}}/resourcegroups/{{OffResGroup}}/ providers/Microsoft.Logic/workflows/{{CmtLAName}}/triggers/{{TriggerName}}/setState?api-version=2016-06-01 来尝试这个。有什么想法吗？
嗨，史蒂夫，请看我的更新。希望这能给你一个可行的解决方案:)
Jamie，非常感谢，它看起来会起作用（我只需要比逻辑应用程序贡献者更精细的权限，因为工作流必须更新一堆资源）。我会尽快将其标记为已回答。干杯！
没问题。您可以使用操作 "Microsoft.Logic/workflows/write" 可分配范围 "/subscriptions/{{SubscriptionID}}/resourceGroups/{{OffResGroup}}/{{CmtLAName}}" 创建自定义角色定义
