自动填充用户名和密码WKWebview Swift 3 Xcode

Question

我想在Swift 3中使用WKWebView类去一个网站并在用户名和密码中进行自动填充。我已经尝试过搜索几天，只能使用Obj-C和旧版本的swift找到答案。

我试着用这里提出Autofill Username and Password UIWebView Swift

解决方案然而，这并没有斯威夫特3.工作对我来说这是我的示例代码：

import Foundation 
import UIKit 
import WebKit 

class spot: UIViewController, UIWebViewDelegate { 

@IBOutlet weak var container: UIView! 
var webView: WKWebView! 

override func viewDidLoad() { 
    super.viewDidLoad() 
    // Do any additional setup after loading the view, typically from a nib. 

    webView = WKWebView() 
    container.addSubview(webView) 

} 

override func viewDidAppear(_ animated: Bool) { 
    let frame = CGRect(x:0, y:0, width:container.bounds.width, height:container.bounds.height) 
    webView.frame = frame 

    // Insert URL below to change launched page 
    let urlStr = "https://login.salesforce.com/" 
    let url = NSURL(string: urlStr)! 
    let request = NSURLRequest(url: url as URL) 
    webView.load(request as URLRequest) 

} 

func webViewDidFinishLoad(_ webView: UIWebView!) { 

    let savedUsername = UserDefaults.standard.string(forKey: "USERNAME") 
    let savedPassword = UserDefaults.standard.string(forKey: "PASSWORD") 

    if savedUsername == nil || savedPassword == nil {return} 

    if (countElements(savedUsername!) != 0 && countElements(savedPassword!) != 0) { 
     let loadUsernameJS = "var inputFields = document.querySelectorAll(\"input[name='username']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedUsername)\';}" 
     let loadPasswordJS = "var inputFields = document.querySelectorAll(\"input[name='password']\"); \\ for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = \'\(savedPassword)\';}" 

     self.webView.stringByEvaluatingJavaScriptFromString(loadUsernameJS) 
     self.webView.stringByEvaluatingJavaScriptFromString(loadPasswordJS) 
    } 
} 


override func didReceiveMemoryWarning() { 
    super.didReceiveMemoryWarning() 
    // Dispose of any resources that can be recreated. 
} 



}

我知道它有点晚，但这里是我的我如何使它工作的代码。这就是说服务器期望字符串，因为我构建它，但我希望你有关于你的特定服务器如何构建URLRequest的信息。

@IBOutlet weak var loadingWebPage: UIActivityIndicatorView! 


override func viewDidLoad() { 
    super.viewDidLoad() 

    let savedUsername = UserDefaults.standard.string(forKey: "USERNAME") 
    let savedPassword = UserDefaults.standard.string(forKey: "PASSWORD") 
    let urlStr = "https://login.salesforce.com/" 

    myWebView = WKWebView() 
    myWebView.uiDelegate = self 
    myWebView.navigationDelegate = self 

    setUrlString = "\(urlStr)?username=\(savedUsername)&password=\(savedPassword)" 
    } 

override func viewWillAppear(_ animated: Bool) { 

    view.addSubview(myWebView) 
    myWebView.translatesAutoresizingMaskIntoConstraints = false 
    let width = NSLayoutConstraint(item: myWebView, attribute: .width, relatedBy: .equal, toItem: view, attribute: .width, multiplier: 1.0, constant: 0) 
    let height = NSLayoutConstraint(item: myWebView, attribute: .height, relatedBy: .equal, toItem: view, attribute: .height, multiplier: 1.0, constant: -70) 
    let top = NSLayoutConstraint(item: myWebView, attribute: .top, relatedBy: .equal, toItem: view, attribute: .top, multiplier: 1.0, constant: 70) 
    view.addConstraints([width,height,top]) 
    self.myWebView.addSubview(loadingWebPage) 

    let myURL = URL(string: setUrlString) 
    let myRequest = URLRequest(url: myURL!) 
    myWebView.load(myRequest) 

} 

希望这会有所帮助。
