Microsoft.Solutions.ArmApiControl UI element

  • Artikkeli

The ArmApiControl gets results from an Azure Resource Manager API operation using GET or POST. You can use the results to populate dynamic content in other controls.

UI sample

There's no UI for ArmApiControl.

Schema

The following example shows the control's schema.

{
  "name": "testApi",
  "type": "Microsoft.Solutions.ArmApiControl",
  "request": {
    "method": "{HTTP-method}",
    "path": "{path-for-the-URL}",
    "body": {
      "key1": "value1",
      "key2": "value2"
    }
  }
}

Sample output

The control's output isn't displayed to the user. Instead, the operation's results are used in other controls.

Remarks

  • The request.method property specifies the HTTP method. Only GET or POST are allowed.

  • The request.path property specifies a URL that must be a relative path to an Azure Resource Manager endpoint. It can be a static path or can be constructed dynamically by referring output values of the other controls.

    For example, an Azure Resource Manager call into the Microsoft.Network/expressRouteCircuits resource provider.

    "path": "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.Network/expressRouteCircuits/{circuitName}?api-version=2022-01-01"

  • The request.body property is optional. Use it to specify a JSON body that is sent with the request. The body can be static content or constructed dynamically by referring to output values from other controls.

Example

In the following example, the providersApi element uses the ArmApiControl and calls an API to get an array of provider objects.

The providersDropDown element's allowedValues property is configured to use the array and get the provider names. The provider names are displayed in the dropdown list.

The output property providerName shows the provider name that was selected from the dropdown list. The output can be used to pass the value to a parameter in an Azure Resource Manager template.

  "$schema": "https://schema.management.azure.com/schemas/0.1.2-preview/CreateUIDefinition.MultiVm.json#",
  "handler": "Microsoft.Azure.CreateUIDef",
  "version": "0.1.2-preview",
  "parameters": {
    "basics": [
      {
        "name": "providersApi",
        "type": "Microsoft.Solutions.ArmApiControl",
        "request": {
          "method": "GET",
          "path": "[concat(subscription().id, '/providers/Microsoft.Network/expressRouteServiceProviders?api-version=2022-01-01')]"
        }
      },
      {
        "name": "providerDropDown",
        "type": "Microsoft.Common.DropDown",
        "label": "Provider",
        "toolTip": "The provider that offers the express route connection.",
        "constraints": {
          "allowedValues": "[map(basics('providersApi').value, (item) => parse(concat('{\"label\":\"', item.name, '\",\"value\":\"', item.name, '\"}')))]",
          "required": true
        },
        "visible": true
      }
    ],
    "steps": [],
    "outputs": {
      "providerName": "[basics('providerDropDown')]"
    }
  }
}

For an example of the ArmApiControl that uses the request.body property, see the Microsoft.Common.TextBox single-line example. That example checks the availability of a storage account name and returns a message if the name is unavailable.
