一般登录网页(使用 JS、PHP 等)都会使用POST
请求,对吗?
特别是在您的网站上,针对用户hello
用密码world
the POST
看起来像下面这样:
您的特定请求标头在哪里:
LoginUser: c7e28a618886dba19eac0892ad90cf51
RTrn: http://m.falalem.com/User-Info
EPostam (user): hello
Sifrem (password): world
同样,在 Swift 中,您将加载一个UIWebView
有类似的要求。据推测,您正在从以下位置接收用户名和密码:UITextField
s 并将使用它们登录UIWebView
:
@IBOutlet weak var usernameTextField: UITextField!
// Note: you will want to secure this either by checking the box
// in Attributes Inspector or programmatically using
// `passwordTextField.secureTextEntry = true`
@IBOutlet weak var passwordTextField: UITextField!
@IBOutlet weak var webView: UIWebView!
...
// fire when the UIButton for "sign in" or "Giriş Yap" is pressed
@IBAction func signIn(sender: AnyObject) {
var url = NSURL(string: "http://m.falalem.com/System/Falalem")
// Note that you will want to use a `NSMutableURLRequest`
// because otherwise, you will not be able to edit the `request.HTTPMethod`
var request = NSMutableURLRequest(URL: url!)
// You need to specifically tell the request what HTTP method to use
// (e.g., GET, POST, PUT, DELETE)
request.HTTPMethod = "POST"
// Is this generated/an API key? If generated per user, use `var`
let loginUser: String = "c7e28a618886dba19eac0892ad90cf51"
// The page you want to go to after login
let redirectPage: String = "http://m.falalem.com/User-Info"
// Get the user's credentials from the `UITextField`s
var username: String = usernameTextField.text
var password: String = passwordTextField.text
// Concatenating everything together
var userCredentials: String = "EPostam=\(username)&Sifrem=\(password)"
var bodyData: String = "\(userCredentials)&RTrn=\(redirectPage)&LoginUser=\(loginUser)"
// Encode the bodyData string into a
request.HTTPBody = bodyData.dataUsingEncoding(NSUTF8StringEncoding)
// load the UIWebView `webView` with this request
webView.loadRequest(request)
}
现在,如果您没有通过以下方式获取用户的凭据UITextField
s,您可以简单地继续
let url = NSURL(string: "http://m.falalem.com")
let request = NSURLRequest(URL: url!)
webView.loadRequest(request)
因为用户只需通过移动网站输入他/她的凭据并以这种方式重定向。
最后,您可能需要使用 SSL,因为否则您将以纯文本形式发送密码(或哈希值),这是不安全的。
