Azure触发器链接模板defaultValue

父母亲json

...
parameters: {
  foo: {
    type: "string"
  }
},
resources: [{
  type: "Microsoft.Resources/deployments",
  properties: {
    templateLink: {
      uri: "sub.json",
      contentVersion: "1.0.0.0"
    },
    parameters: {
      bar: {
        value: "[parameters('foo')]"
      }
    }
  }
}]
...

...
parameters: {
  bar: {
    type: "string",
    allowedValues: ["larry", "moe", "curly"],
    defaultValue: "curly"
  }
}
...

不幸的是,通过了 无效的 父模板中的foo值将出错 The value of deployment parameter 'foo' is null . 如果我为foo传递一个空字符串,它将出错 The provided value '' for the template parameter 'bar' is not valid. The parameter value is not part of the allowed value(s): 'larry,moe,curly' .

我试着让父母帮忙。json

...
resources: [{
  type: "Microsoft.Resources/deployments"
  properties: {
  ...
    parameters: {
      bar: {
        value: "[if(empty(parameters('foo')), json('null'), parameters('foo'))]"
      }
    }
  }
}]
...

但它只会给出相同的值,即null。我知道这可以在AWS嵌套堆栈中使用value来完成 aws::NoValue
