azure - 逻辑应用标准工作流触发器失败

Question

我们创建了一个使用服务总线 API 连接的逻辑应用标准。当查看“连接”选项卡时，它显示连接处于“已连接”状态。

问题是工作流的触发失败，输出 json 如下:

{
    "statusCode": 401,
    "headers": {
        "Cache-Control": "no-store, no-cache",
        "Pragma": "no-cache",
        "x-ms-request-id": "xxxx",
        "Strict-Transport-Security": "max-age=31536000; includeSubDomains",
        "X-Content-Type-Options": "nosniff",
        "X-Frame-Options": "DENY",
        "Timing-Allow-Origin": "*",
        "x-ms-apihub-cached-response": "true",
        "x-ms-apihub-obo": "true",
        "Date": "Wed, 20 Jul 2022 15:21:08 GMT",
        "Content-Length": "287",
        "Content-Type": "application/json",
        "Expires": "-1"
    },
    "body": {
        "status": 401,
        "message": "Key 'token' not found in connection profile.\r\nclientRequestId: 0b492f59-bca5-4901-8132-b0ce10416d25",
        "error": {
            "message": "Key 'token' not found in connection profile."
        },
        "source": "servicebus-xxx.azurewebsites.net"
    }
}

这里可能出现什么问题？

这可能是由于权限限制吗？

Answer 1

对我来说，这个问题的解决方案不在 API 连接本身，而是在逻辑应用本身的connections.json 文件中。任何地方都没有文档描述对连接的“connectionProperties”部分的需求。我通过对门户创建的标准逻辑应用程序进行逆向工程发现了它。

{
  "managedApiConnections": {
    "servicebus-central": {
      "api": {
        "id": "/subscriptions/..."
      },
      "authentication": {
          "type": "ManagedServiceIdentity"
      },
      "connection": {
        "id": "/subscriptions/..."
      },
      "connectionRuntimeUrl": "@appsetting('ServiceBusCentralConnectionRuntimeUrl')",
      "connectionProperties": {
        "authentication": {
            "audience": "https://servicebus.azure.net",
            "type": "ManagedServiceIdentity"
        }
      }
    }
  }
}
