使用保存的用户名和密码以编程方式登录网站 [英] Programmatically logging in to website with saved username and password

问题描述

我正在制作的一个应用程序的功能之一是将用户登录到我们的校园门户网站。为了便于使用，用户可以在应用程序中输入用户名和密码一次，并将其保存用于所有未来的登录。当用户点击一个按钮时，会自动发送信息以登录，并且该网站将显示在 UIWebView 中。

让我们说，用户名和密码都存储在 NSString 中。我如何使用此数据以编程方式登录此网站并显示它在一个 UIWebView ？

我对发布和表单知之甚少， p>

类似于

这里是我的代码的shell这个

   - （IBAction）btnGo：（id）sender {
 username = usernameField.text; 
 password = passwordField.text; 
 if（saveSwitch.isOn）{
 //如果用户想要保存数据
 AppDelegate * appDelegate =（AppDelegate *）[[UIApplication sharedApplication] delegate]; 
 usernameSaved = username; 
 passwordSaved =密码; 
 [appDelegate.listOfPortalCredentials replaceObjectAtIndex：0 withObject：usernameSaved]; 
 [appDelegate.listOfPortalCredentials replaceObjectAtIndex：1 withObject：passwordSaved]; 
} 
 //将用户名和密码插入网页表单，登录到门户
 //这是我需要帮助的地方
}

感谢Karthik，我能够使用Firebug找到HTTP Post。它给了我：
 
 
  appName = ridgefield& portalUrl = portal％2Fridgefield.jsp％3F％26rID％3D0.18423783694092& username = < username>& password =< password>& B1 = Log + In& url = portal％2Fmain.xsl％3FrID％3D0.6845596700302482& lang = en 
  pre> 
 
 
其中代表真正的用户名和密码。我相信这是我需要的。使用这个，我怎样才能在 UIWebView 中显示登录页面？我只需要在 UIWebView 中加载上面的URL？
解决方案
使用UIWebView，并执行http POST来 https://ic.ridgefield.org/campus/verify使用用户名和密码。
 
 
 
要了解它的工作原理，请在Firefox浏览器上安装Firebug并转到萤火虫上的'Net'选项卡，然后打开您的网站并输入一些用户名/密码。
 
 
 
您应该使用代码模仿该操作。 （我总是从服务器得到无效的用户名或密码响应，因为我没有帐户，我尝试了一些随机的，因为没有在网站上注册，所以我没有办法验证这一点）
  UIWebView * webView = [[UIWebView alloc] initWithFrame：self.view.frame]; 
 [self.view addSubview：webView]; 
 
 NSString * username = @; 
 NSString * password = @; 
 
 NSURL * url = [NSURL URLWithString：@https://ic.ridgefield.org/campus/verify.jsp]; 
 
 NSString * body = [NSString stringWithFormat：@appName = ridgefield& username =％@& password =％@，username，password]; 
 NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL：url cachePolicy：NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval：30]; 
 request.HTTPMethod = @POST; 
 request.HTTPBody = [body dataUsingEncoding：NSStringEncodingConversionAllowLossy]; 
 
 [webView loadRequest：request]; 
  
 
One of the functions of an app I am making involves logging the user into our Campus Portal website.  For ease of use, the user may enter a username and password into the app once, and it will be saved for all future log-ins.  When the user clicks a button, the information will automatically be sent to log in, and the website will be displayed in a UIWebView.

Let us say that the username and password are each stored in an NSString.  How can I use this data to log in to this website programmatically and display the page it in a UIWebView?

I know little about posting and forms, so any help is appreciated.

Would something like this Stackoverflow answer help?

Here's the shell of my code for this
- (IBAction)btnGo:(id)sender {
    username = usernameField.text;
    password = passwordField.text;
    if (saveSwitch.isOn) {
        //Save data if the user wants
        AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
        usernameSaved = username;
        passwordSaved = password;
        [appDelegate.listOfPortalCredentials replaceObjectAtIndex:0 withObject:usernameSaved];
        [appDelegate.listOfPortalCredentials replaceObjectAtIndex:1 withObject:passwordSaved];
    }
    //Insert username and password to web form, log in to portal
    //This is where I need help
}
Edit:

Thanks to Karthik I was able to find the HTTP Post using Firebug.  It gave me:
appName=ridgefield&portalUrl=portal%2Fridgefield.jsp%3F%26rID%3D0.18423783694092&username=<username>&password=<password>&B1=Log+In&url=portal%2Fmain.xsl%3FrID%3D0.6845596700302482&lang=en
where  and  represent the real username and password.  I believe this is what I need.  Using this, how can I display the logged-in page in a UIWebView?  Do I just need to load the above URL in the UIWebView?
解决方案
Use UIWebView, and do a http POST to https://ic.ridgefield.org/campus/verify.jsp with username and password.

To understand how it works, install Firebug on Firefox browser and go to 'Net' tab on firebug, and then open your website and enter some username/password.

You should mimic that action using code. (I always get invalid username or password response from server, coz i dont have an account and i try some random ones, and since there is no signup on the site, there is no way for me to verify this)
UIWebView* webView = [[UIWebView alloc] initWithFrame:self.view.frame];
[self.view addSubview:webView];

NSString* username = @"";
NSString* password = @"";

NSURL* url = [NSURL URLWithString:@"https://ic.ridgefield.org/campus/verify.jsp"];

NSString* body = [NSString stringWithFormat:@"appName=ridgefield&username=%@&password=%@", username, password];
NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30];
request.HTTPMethod = @"POST";
request.HTTPBody = [body dataUsingEncoding:NSStringEncodingConversionAllowLossy];

[webView loadRequest:request];
