Question

我正在尝试使用Azure Logic SDK更新逻辑应用程序的重复频率和间隔，但是此错误消息失败

Microsoft.Rest.Azure.CloudException ：不支持修补工作流程'kk-test-logic-app'的请求。可以修补属性对象中的所有字段。

这是一段代码片段，展示了我要做的事情。

    var workflow = await _client.Value.Workflows.GetAsync(resourceGroupName, workflowName);

    dynamic workflowDefinition = workflow.Definition;
    workflowDefinition.triggers[triggerName]["recurrence"] = JToken.FromObject(new { frequency = triggerFrequency, interval = triggerInterval });

    await _client.Value.Workflows.UpdateAsync(resourceGroupName, workflowName, workflow);

其中_client为Lazy<LogicManagementClient>。

以下是我尝试更新的触发器的定义（使用Fiddler）：

  "triggers": {
    "When_a_new_email_arrives": {
      "recurrence": {
        "frequency": "Hour",
        "interval": 2
      },
      "splitOn": "@triggerBody()?.value",
      "type": "ApiConnection",
      "inputs": {
        "host": {
          "api": {
            "runtimeUrl": "https://logic-apis-southindia.azure-apim.net/apim/office365"
          },
          "connection": {
            "name": "@parameters('$connections')['office365']['connectionId']"
          }
        },
        "method": "get",
        "path": "/Mail/OnNewEmail",
        "queries": {
          "folderPath": "Inbox",
          "importance": "Any"
        }
      }
    }
  }

请注意，我能够成功检索工作流，workflowRuns，workflowTriggers等。只有更新操作失败。有关如何使用SDK更新工作流属性的任何想法？

更新正如Amor-MSFT在下面的评论中所指出的，这是一个缺陷，作为一种解决方法，我目前正在使用CreateOrUpdateAsync而不是UpdateAsync。已在GitHub中创建new defect以引起SDK开发团队的注意。

触发器当前每30秒执行一次，检查是否从某个电子邮件地址收到了新邮件，并且是否按预期运行良好。我正在尝试使用我提供的代码将重复频率从30秒更改为2小时。

我创建了一个邮件触发器，如果我使用调用UpdateAsync方法，我可以重现该问题。根据Azure Logic C＃SDK的source code，它根据响应消息发送不支持的PATCH请求。将HTTP方法更改为PUT后，我可以更新工作流程。这是我用来发送PUT请求的示例代码。

string triggerName = "When_a_new_email_arrives";
string resourceGroupName = "my resourcegroup name";
string workflowName = "my-LogicApp";
string subscriptionID = "my-subscriptionID";
var workflow = await _client.Workflows.GetAsync(resourceGroupName, workflowName);

string url = string.Format("https://management.azure.com/subscriptions/{0}/resourceGroups/{1}/providers/Microsoft.Logic/workflows/{2}?api-version=2016-06-01",
    subscriptionID, resourceGroupName, workflowName);
HttpClient client = new HttpClient();
HttpRequestMessage message = new HttpRequestMessage(HttpMethod.Put, url);
message.Headers.Add("Authorization", "Bearer put your token here");
message.Headers.Add("Accept", "application/json");
message.Headers.Add("Expect", "100-continue");

dynamic workflowDefinition = workflow.Definition;
workflowDefinition.triggers[triggerName]["recurrence"] = JToken.FromObject(new { frequency = "Minute", interval = 20 });

string s = workflow.ToString();
string workflowString = JsonConvert.SerializeObject(workflow, _client.SerializationSettings);

message.Content = new StringContent(workflowString, Encoding.UTF8, "application/json");
await client.SendAsync(message);
