嗨，我在为POST请求获取正确的数据格式方面遇到了一些挑战。
我有两个功能，一个是执行GET请求，如下所示（我正在使用alamofire）：
func performRequestRdw(dataURL: String, headers: HTTPHeaders) {
AF.request(dataURL, method: .get, headers: headers).responseJSON { response in
debugPrint(response)
if let safeData = response.data {
if let rdwVehicle = self.parseRdwJSON(rdwData: safeData) {
print("safeData is: \(safeData)")
self.delegate?.didUpdateRdwInfo(rdwData: rdwVehicle)
self.performRequestAddVehicle(dataURL: self.addVehicleUrl, headers: headers, parameters: rdwVehicle)
}
}
}
}
func parseRdwJSON(rdwData: Data) -> RdwModel? {
let decoder = JSONDecoder()
do {
let decodedData = try decoder.decode(RdwData.self, from: rdwData)
print("plateNumber is: \(decodedData.plateNumber)")
let hasBasicInsurance = decodedData.hasBasicInsurance
let nextInspectionDate = decodedData.nextInspectionDate
let platNumber = decodedData.plateNumber
let brand = decodedData.vehicle.brand
let model = decodedData.vehicle.model
let orginalPrice = decodedData.originalPrice.amount
let currency = decodedData.originalPrice.currency
let rdwData = RdwModel(hasBasicInsurance: hasBasicInsurance, nextInspectionDate: nextInspectionDate, plateNumber: platNumber, brand: brand, model: model, currency: currency, amount: orginalPrice)
do {
let data = try JSONEncoder().encode(rdwData)
print("data is: \(data)")
} catch {
print(error)
}
return rdwData
}catch {
delegate?.didFailWithError(error: error)
print(">>>Error is \(error)")
return nil
}
}
另一个是通过API发送数据的POST函数：
func performRequestAddVehicle(dataURL: String, headers: HTTPHeaders, parameters: Parameters) {
AF.request(dataURL, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers: headers).responseJSON { response in
debugPrint(response)
}
}
我在 self.performRequestAddVehicle(dataURL: self.addVehicleUrl, headers: headers, parameters: rdwVehicle)函数的performRequestRdw中出错。
它表示“ 无法将'RdwModel'类型的值转换为预期的参数类型'Parameters'（aka'Dictionary
我的问题是：如何从GET请求转换正确的数据格式，然后在POST请求中使用它。参数POST请求询问的是字典。我找不到一种很好的方法。
非常感谢您的帮助；-）
