使用Alamofire和Codable提出看跌请求 [英] Using Alamofire and Codable for put request

问题描述

我有一个简单的放置请求，我正在使用Alamofire的Parameters类型将数据发送到服务器.我想使用codable.如何将我的可编码结构转换为参数，或者重新配置Alamofire请求以将JSON对象作为参数?使用Alamofire发送帖子请求和放置请求的最好，最有效的方法是什么?

I have a simple put request and I am using Alamofire's Parameters type to send data to the server. I would like to use codable. How do I either convert my codable struct to parameters or reconfigure the Alamofire request to take JSON objects as the parameter? What is the best and most efficient way to send post and put requests using Alamofire?

这就是我现在正在使用Alamofire进行的操作.

Here is what I am doing right now with Alamofire.

func addProduct(product:MainProduct, completionHandler:@escaping ((JSON?, Error?)->Void)) {

    let url = "INSERT_URL"

    let headers: HTTPHeaders = [
        "Content-Type": "application/json"
    ]

    var parameters:Parameters = [:]
    parameters["orderId"] = product.orderId
    parameters["orderSize"] = product.orderSize
    parameters["theOrderStatus"] = product.orderStatus
    let purchDate = Int((product.purchaseDate.timeIntervalSince1970)*1000)
    parameters["purchaseDate"] = purchDate
    parameters["archived"] = false

    Alamofire.request(url, method:.put, parameters: parameters, encoding: JSONEncoding.default, headers:headers).responseJSON {response in
        switch response.result {
        case .success(let value):
            print ("finish")
            let swiftyJson = JSON(value)
            completionHandler(swiftyJson, nil)
        case .failure(let error):
            completionHandler(nil, error)
        }
    }
}

这是我们的结构.

struct MainProduct:Codable{

    var purchaseDate:Date
    var orderId:String
    var orderSize:Double
    var orderStatus:OrderStatus?

    var archived:Bool

    private enum CodingKeys: String, CodingKey {
        case purchaseDate
        case orderId
        case orderSize
        case orderStatus = "theOrderStatus"
        case archived
    }
}

推荐答案

您可以创建一个新的URLRequest并将httpBody设置为已编码的jsonData.试试这个代码...

You can make a new URLRequest and set httpBody to your encoded jsonData. Try this code...

func addProduct(product: MainProduct, completionHandler: @escaping ((JSON?, Error?)->Void)) {

    let encoder = JSONEncoder()
    let jsonData = try! encoder.encode(product)

    let url = "INSERT_URL"

    var request = URLRequest(url: url)
    request.httpMethod = HTTPMethod.put.rawValue
    request.setValue("application/json; charset=UTF-8", forHTTPHeaderField: "Content-Type")
    request.httpBody = jsonData

    Alamofire.request(request).responseJSON { response in
        switch response.result {
        case .success(let value):
            print ("finish")
            let swiftyJson = JSON(value)
            completionHandler(swiftyJson, nil)
        case .failure(let error):
            completionHandler(nil, error)
        }
    }
}
