Question

我遇到了HTTP request.it没有显示任何错误。编译器读取前两行并跳过代码“task.resume（）”。我在其他视图控制器上获取具有相同代码的数据但是它这里有创造问题

func getCustomers()
{
    let url = NSURL(string: "myURL.com")
    let task = URLSession.shared.dataTask(with: url! as URL) {
        (data, response, error) in

        guard let _:Data = data, let _:URLResponse = response  , error == nil else {
            print("error: \(String(describing: error))")

            return
        }
        do
        {
            self.getcustomersArray = [GetCustomers]()
            //JSON Parsing
            if let data = data,

                let json = try JSONSerialization.jsonObject(with: data) as? [String: Any]
            {
                let results = json["Result"] as? [[String : Any]]

                let getCustomersObject:GetCustomers = GetCustomers()
                for result in results!
                {
                    getCustomersObject.ActivityPrefix = (result["ActivityPrefix"] as? String)!
                    getCustomersObject.CustomerID = (result["CustomerID"] as? String)!
                    getCustomersObject.CustomerName = (result["CustomerName"] as? String)!
                    getCustomersObject.TFMCustomerID = (result["TFMCustomerID"] as? String)!
                    getCustomersObject.ShortName = (result["ShortName"] as? String)!
                    getCustomersObject.UserRights = (result["UserRights"] as? Int)!

                    self.totalCustomers += self.totalCustomers
                }
                self.customerName = getCustomersObject.CustomerName

            }
        }//end Do
        catch
        {

        }
    }

    task.resume()
}

使用Block GET / POST / PUT / DELETE：

 let request = NSMutableURLRequest(url: URL(string: "Your API URL here" ,param: param))!,
        cachePolicy: .useProtocolCachePolicy,
        timeoutInterval:"Your request timeout time in Seconds")
    request.httpMethod = "GET"
    request.allHTTPHeaderFields = headers as? [String : String] 

    let session = URLSession.shared

    let dataTask = session.dataTask(with: request as URLRequest) {data,response,error in
        let httpResponse = response as? HTTPURLResponse

        if (error != nil) {
         print(error)
         } else {
         print(httpResponse)
         }

        DispatchQueue.main.async {
           //Update your UI here
        }

    }
    dataTask.resume()

我想你不提线 request.httpMethod =＆＃34; GET＆＃34;
