带有基本身份验证的 iOS swift Web 服务调用

Question

我疯狂地尝试从网络服务获取一些数据(JSON)。

有人可以告诉我如何在此通话中添加用户名和密码身份验证吗？一定不能像下面的代码那样。如果您有一些适用于 swift 3.0 的代码，我很乐意看到它。

func downloadData()
{
    let url = NSURL(string: "https://www.someurl.com")
    let request = NSMutableURLRequest(url: url! as URL)

    let task = URLSession.shared.dataTask(with: request as URLRequest) { data,response,error in
        guard error == nil && data != nil else
        {
            print("Error:",error!)
            return
        }

        let httpStatus = response as? HTTPURLResponse

        if httpStatus!.statusCode == 200
        {
            if data?.count != 0
            {
                let responseString = try! JSONSerialization.jsonObject(with: data!, options: .allowFragments) as! NSDictionary //because JSON data started with dictionary. Not an array
                let status = responseString["status"] as! String

                if status == "ok"
                {
                    print("Status is :", status)

                    //Ok, so far so good. Now let's get the data...
                }
                else
                {
                    print("Status is not Okay!")
                }
            }
            else
            {
                print("No data got from url!")
            }
        }
        else
        {
            print("error httpstatus code is :",httpStatus!.statusCode)
        }
    }
    task.resume()
}

这取决于您的网络服务，但您需要将这些值添加到您的请求中。

例如，向 header 添加值:

let request = NSMutableURLRequest(url: url! as URL)
request.addValue("An_Authentication_String", forHTTPHeaderField: "MyField")

或者您可能需要向您的请求添加正文:How to make HTTP Post request with JSON body in Swift
