使用Rx编程Moya将JSON响应映射到对象

我尝试使用ModelMapper库的mapObject函数,如下所示:

return provider.request(API.userInfo(userId: API.userId))
            .mapObject(type: UserTest.self, keyPath: "user")

{
    "success": true,
    "user": {
        "_id": "HJzCZaXEW",
        "mail": "Valentin",
        "__v": 0,
        "bikes": [
            "S1rjHamNZ",
            "HkxhHpXEZ"
        ],
        "updated": "2017-06-30T12:19:22.016Z",
        "created": "2017-06-30T12:19:22.015Z"
    }
}

我试着用这种方法看看有什么错误:

API.getUserInfo()
        .subscribe {event in
            switch event {
            case .next(let response):
                print(response)
            case .error(let error):
                print("error")
                print(error)
            default:
                print("default")
            }
        }

我在控制台上看到了这个:

error
jsonMapping(Status Code: 200, Data Length: 177)

import Mapper

struct UserTest: Mappable {
    var name: String
    var lastname: String
    var mail: String
    var bikes: [String]

    init(map: Mapper) throws {
        try name = map.from("name")
        try lastname = map.from("lastname")
        try mail = map.from("mail")
        try bikes = map.from("bikes")
    }
}

我也尝试过pod更新,但没有任何改变。

提前感谢您的帮助!
