推荐答案
一般登录网页(使用JS,PHP等)使用POST
请求,对吧?
Logging into a webpage in general (using JS, PHP, etc.) uses a POST
request, right?
特别是在您的网站上,对于密码为world
的用户hello
,POST
如下所示:
Specifically on your website, for the user hello
with the password world
the POST
looks like the following:
where your specific request headers are:
LoginUser: c7e28a618886dba19eac0892ad90cf51
RTrn: http://m.falalem.com/User-Info
EPostam (user): hello
Sifrem (password): world
同样,在Swift中,您将使用类似的请求加载UIWebView
.大概是您从UITextField
接收了用户名和密码,并打算使用它们来登录UIWebView
:
Likewise, in Swift, you're going to load a UIWebView
with a similar request. Presumably, you are receiving the username and password from UITextField
s and are going to use them to login to a 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UITextField
获取用户的凭据,则只需继续进行操作
Now, if you're not getting the user's credentials via UITextField
s, you can simply proceed with
let url = NSURL(string: "http://m.falalem.com")
let request = NSURLRequest(URL: url!)
webView.loadRequest(request)
因为用户随后只需通过移动网站输入他/她的凭据并以这种方式重定向.
because the user will then just input his/her credentials via the mobile website and be redirected that way.
最后,您可能要使用SSL,因为否则您将以纯文本形式发送密码(或哈希),这是不安全的.
Lastly, you'll probably want to use SSL because otherwise you're sending the password (or the hash) over as plain text, which is not secure.
