swift - Alamofire.request().responseObject 不返回响应

Question

我使用 AlamofireObjectMapper 扩展。我想得到回应，但失败了。我的 tableLeague 对象始终为零，因为具有响应闭包的代码不会调用 ({ (response: DataResponse) 如果响应.结果.isSuccess { tableLeague = 响应.结果.值 } 不调用)。我使用以下方法:

let header = ["X-Auth-Token":"1231231"]

static let sharedInstance = ServerAPI()
private func getRequest(uri: String) -> DataRequest {
    return Alamofire.request(uri, method: .get, headers: header)
}

public func getTableLeague() -> TableLeague {
    var tableLeague: TableLeague?
    getRequest(uri: URL).responseObject { (response: DataResponse<TableLeague>) in
        if response.result.isSuccess {
            tableLeague = response.result.value
        }
    }
    return tableLeague!
}

并在商务舱中使用:

public func readTableLeague() -> TableLeague {
    let tableLeague = ServerAPI.sharedInstance.getTableLeague()
    return tableLeague
}

我认为这可能是因为尚未响应，但我尝试设置尚未设置的对象

有什么问题吗？我需要使用其他完成处理程序吗？

请尝试按以下结构进行映射

class Response: Mappable {
    var success: Bool?
    var data: [Data]?

    required init?(_ map: Map) {
        mapping(map)
    }

    func mapping(map: Map) {
        success <- map["success"]
        data <- map["data"]
    }
}

class Data: Mappable {
    var uid: Int?
    var name: String?
    // add other field which you want to map        

    required init?(_ map: Map) {
        mapping(map)
    }

    func mapping(map: Map) {
        uid <- map["uid"]
        name <- map["name"]
    }
}

当您通过此语法获得 JSON 响应简单映射时

let response = Mapper<Response>().map(responseObject)
if let id = response?.data?[0].uid {
    println(id)
}
