Question

我要求的JSON页面需要密码和用户名都是字符串类型。用户名和密码属于开发人员...顺便说一下，它能够到达页面，我无法通过身份验证。

这是api url：https://api.intrinio.com/prices?identifier=AAPL

如果我遗漏了一些信息或代码，请告诉我，我会提供。

class ViewController: UIViewController, UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource {

    //MARK: - Outlets
    @IBOutlet weak var labelTwo: UILabel!
    @IBOutlet weak var tableView: UITableView!
    @IBOutlet weak var tickerTextField: UITextField!

    //MARK: - Properties
    let userPasswordString = ""
    let userPassword = ""

    //MARK: - View Did Load
    override func viewDidLoad() {
        tickerTextField.textColor = UIColor.lightGray
        tickerTextField.text = "Search Ticker"
        tickerTextField.delegate = self

        let jsonUrlString = "https://api.intrinio.com/prices?identifier=\(ticker)"
        print(jsonUrlString)
        guard let url = URL(string: jsonUrlString) else { return }
        URLSession.shared.dataTask(with: url) { (data, response, err) in
            let dataAsString = String(data: data!, encoding: .utf8)
            print(dataAsString!)
            guard let data = data else { return }
            do {
                let jsonDecoder = JSONDecoder()
                let tickerPrice = try jsonDecoder.decode(TickerPrice.self, from: data)
                DispatchQueue.main.async {
                   print(tickerPrice.name)
                }
            } catch let jsonErr {
                print("Error serielaising jason", jsonErr)
            }
            }.resume()

    }

来自documentation：

私人授权您访问Intrinio API：
// With shell, you must include the username and 
// password header
curl "https://api.intrinio.com/data_point?identifier=AAPL&item=close_price"
  -u "API_USERNAME:API_PASSWORD"

// With the '-u' option in curl, it will automatically
// convert the username and password into the 
// appropriate header. If you do not use this 
// option or it is not available to you, you must 
// include a header with the basic auth credentials 
// included as base64 encoded.
curl "https://api.intrinio.com/data_point?identifier=AAPL&item=close_price"
  -H "Authorization: Basic $BASE64_ENCODED(API_USERNAME:API_PASSWORD)"
对于私有/受信任环境，请使用基于HTTPS的基本身份验证。

您可以在“帐户”页面上找到API用户名和API密码。   您必须在每个请求中包含这些凭据   获得对API的访问权。

要在HTTPS请求中包含凭据，请指定   授权标头，值为Basic（键），替换（键）   Base-64编码的字符串API_USERNAME：API_PASSWORD。

如果您的凭据未经授权，则状态代码为401   返回。

您必须使用API密钥替换API_USERNAME和API_PASSWORD   可在API管理控制台上找到。

为此，您需要使用URLRequest，而不仅仅是URL：

//Create URLRequest
var request = URLRequest.init(url: url!)

//Create Header according to the documentation
let userName = "API_USERNAME" //Need to be replaced with correct value
let password = "API_PASSWORD" //Need to be replaced with correct value
let toEncode = "\(userName):\(password)" //Form the String to be encoded
let encoded = toEncode.data(using: .utf8)?.base64EncodedString()

//Add the header value
request.addValue("Basic \(encoded!)", forHTTPHeaderField: "Authorization")

//Perform the task with the request instead of previously the URL
URLSession.shared.dataTask(with: request){//The rest of your code}

旁注，我没有guard let或if let，我在需要时难以打开。它是显示主要逻辑和CocoaTouch API而不是其他任何东西，特别是因为我不是Swift开发人员。

使用JSON进行基本身份验证
