NSURLSession 认证
NSURLSession Authentication
我尝试使用找到的 swift 代码 here on the website found here,但响应是 html 代码,有两个错误:"You must enter a password!" 和 "You must enter a User name!" 我我是 NSURLSession 的新手,并尝试更改用于身份验证的字符串,但没有任何方法可以更改响应。这是我的代码:
let config = NSURLSessionConfiguration.defaultSessionConfiguration()
let userPasswordString = "username@gmail.com:password"
let userPasswordData = userPasswordString.dataUsingEncoding(NSUTF8StringEncoding)
let base64EncodedCredential = userPasswordData!.base64EncodedStringWithOptions(NSDataBase64EncodingOptions.Encoding64CharacterLineLength)
let authString = "Basic \(base64EncodedCredential)"
config.HTTPAdditionalHeaders = ["Authorization" : authString]
let session = NSURLSession(configuration: config)
var running = false
let url = NSURL(string: "https://hac.chicousd.org/")
let task = session.dataTaskWithURL(url!) {
(let data, let response, let error) in
if (response as? NSHTTPURLResponse) != nil {
let dataString = NSString(data: data!, encoding: NSUTF8StringEncoding)
print(dataString)
}
running = false
}
running = true
task.resume()
while running {
print("waiting...")
sleep(1)
}
这是在控制台响应中:
<!-- Start Error box -->
<div id="errorContainer" class="alert alert-danger" style="display:none;">
<button id="portalCloseError" type="button" class="close"> ×</button>
<span id="errorMessage" class="error" data-pw-error="You must enter a password!" data-username-error="You must enter a User Name!"></span>
</div> <!-- End Error box -->
有两种方法可以登录网站:HTTP 授权和表单。大多数网站使用较晚的、对用户更友好的登录表单。 HTTP 授权仅在网站 期望 与用户程序交互时使用(不,浏览器不算在这里)。
在编写代码之前,您需要先了解网站发送的数据格式,因为了解就成功了一半:
- 访问 the school website 并按
Cmd + Opt + C
打开开发者控制台。
- 单击网络 选项卡。
- 不要关闭此控制台。返回网站并像往常一样输入您的用户名和密码。
观察页面发送什么数据:
纯文本:
checkCookiesEnabled true
checkMobileDevice false
checkStandaloneMode false
checkTabletDevice false
portalAccountUsername email
portalAccountPassword password
portalAccountUsernameLabel
因此用户名在名为 portalAccountUsername
的字段中传递,密码在 portalAccountPassword
中传递。其他字段可能重要也可能不重要。
现在您可以编写代码了:
@IBAction func login(sender: AnyObject) {
let url = NSURL(string: "https://hac.chicousd.org/LoginParent.aspx")!
// The form parameters
let parameters = [
"checkCookiesEnabled": "true",
"checkMobileDevice": "false",
"checkStandaloneMode": "false",
"checkTabletDevice": "false",
"portalAccountUsername": "username",
"portalAccountPassword": "password"
]
let bodyString = parameters
.map { [=11=] + "=" + }
.joinWithSeparator("&")
.stringByAddingPercentEncodingWithAllowedCharacters(.URLQueryAllowedCharacterSet())!
let request = NSMutableURLRequest(URL: url)
request.HTTPMethod = "POST"
request.HTTPBody = bodyString.dataUsingEncoding(NSUTF8StringEncoding)
let task = NSURLSession.sharedSession().dataTaskWithRequest(request) { data, response, error in
guard error == nil else {
print(error?.localizedDescription)
return
}
guard let data = data else {
print("empty data")
return
}
// This is the HTML source of the landing page after login
let html = String(data: data, encoding: NSUTF8StringEncoding)
}
task.resume()
}
由于某些原因,我 disabled App Transport Security 之前无法提出请求。也许该网站上的资源来自非 HTTPS 域。
