Azure - 逻辑应用程序到服务总线 - JSON 传输

Question

I want to transfer below mentioned JSON response received from http event in Azure Logic App to Azure Service Bus queue .

{
  "properties": {
    "data": {
      "properties": {
        "alertContext": {
          "properties": {},
          "type": "object"
        },
        "essentials": {
          "properties": {
            "alertContextVersion": {
              "type": "string"
            },
            "alertId": {
              "type": "string"
            },
            "alertRule": {
              "type": "string"
            },
            "alertTargetIDs": {
              "items": {
                "type": "string"
              },
              "type": "array"
            },
            "description": {
              "type": "string"
            },
            "essentialsVersion": {
              "type": "string"
            },
            "firedDateTime": {
              "type": "string"
            },
            "monitorCondition": {
              "type": "string"
            },
            "monitoringService": {
              "type": "string"
            },
            "originAlertId": {
              "type": "string"
            },
            "resolvedDateTime": {
              "type": "string"
            },
            "severity": {
              "type": "string"
            },
            "signalType": {
              "type": "string"
            }
          },
          "type": "object"
        }
      },
      "type": "object"
    },
    "schemaId": {
      "type": "string"
    }
  },
  "type": "object"
}

I have used many expressions like encodebase64(string(triggerBody())) but it throws error.

ExpressionEvaluationFailed. The execution of template action 'For_each' failed: the result of the evaluation of 'foreach' expression '@encodebase64(string(triggerBody()))' is of type 'String'. The result must be a valid array.

Here are the images:

1. json response received by logic as webhook: https://github.com/arindam-b/images/blob/master/Logicapp1.PNG

2. Expression in step, to convert json to string, but is looking for foreach: https://github.com/arindam-b/images/blob/master/Logicapp2.PNG

3. Step 2 full view with service bus part: https://github.com/arindam-b/images/blob/master/Logicapp3.PNG

Many thanks for your valuable inputs.

Answer 1

Firstly, your JSON response is in application/json , the you could be able to do for_each action, it will be like the below pic. And suppose you want to send message to Service Bus. The For_each input is triggerbody() and the message content depends you requirement select the property in you json data. My test content is the body property so it should be items('Fior_each')['body'] .

The second scene is your json response in text/plain or other types, in this situation It won't work you use Request Body JSON Schema . You have to parse them to json type then select property. The flow will be like the below pic. The Parse_JSON input is triggerbody() and the for_each input is body('Parse_JSON') .

Before I ask did you want to transfer the whole json to message, you affirm it however from your description and your picture, you want to cut your json data and select the property you want. So if you want to store the whole json, you could store it without schema.
