如何在Vapor 1.5中循环JSON对象并将其转换为[String:Any]？

import Vapor
import JSON

let json: JSON = [
    "key1": "value1",
    "key2": "value2",
    "key3": "value3"
]

var dictionary: [String:Any] = [:]

for (key, value) in json {
    dictionary[key.string ?? ""] = value.wrapped
}

import Vapor
import JSON

let json: JSON = [
    "key1": "value1",
    "key2": "value2",
    "key3": "value3"
]

var dictionary: [String:Any] = [:]

for (key, value) in json {
    dictionary[key.string ?? ""] = value.wrapped
}

print(dictionary)
