访问 angularJs 中的对象时发生未定义错误

Undefined error when accessing object in angularJs

当我访问以下对象时,它抛出未定义的错误,

{
    "code": 422,
    "message": {
        "address_info.email": [
            "The address info.email field is required."
        ]
    },
    "debug": null
}

console.log(data.error.message.address_info.email);

我收到错误 data.error.message.address_info is undefined,那么我怎样才能收到 address_info.email 错误消息?

使用类似地图的语法:

data.error.message["address_info.email"]
