如何在UIWebView中显示身份验证质询？

Question

我正在尝试通过UIWebView访问安全的网站。当我通过野生动物园访问它时，我遇到了身份验证挑战，但是在应用程序的UIWebView中没有出现相同的问题。如何使其显示？

任何指针，示例代码或链接都将非常有帮助。非常感谢。

实际上，这非常容易...我确定您可以在显示auth挑战委托时（或在加载URL之前，如果您确定所击中的URL会提示您输入auth登录信息，则只需显示UIAlertView）即可。 ）。无论如何，诀窍是创建自己的方法NSURLConnection，我做一些逻辑来保存是否使用了auth委托。- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;{    NSLog(@"Did start loading: %@ auth:%d", [[request URL] absoluteString], _authed);    if (!_authed) {        _authed = NO;        /* pretty sure i'm leaking here, leave me alone... i just happen to leak sometimes */        [[NSURLConnection alloc] initWithRequest:request delegate:self];        return NO;    }    return YES;}- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;{    NSLog(@"got auth challange");    if ([challenge previousFailureCount] == 0) {        _authed = YES;        /* SET YOUR credentials, i'm just hard coding them in, tweak as necessary */        [[challenge sender] useCredential:[NSURLCredential credentialWithUser:@"username" password:@"password" persistence:NSURLCredentialPersistencePermanent] forAuthenticationChallenge:challenge];    } else {        [[challenge sender] cancelAuthenticationChallenge:challenge];    }}- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;{    NSLog(@"received response via nsurlconnection");    /** THIS IS WHERE YOU SET MAKE THE NEW REQUEST TO UIWebView, which will use the new saved auth info **/    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:]];    [_webView loadRequest:urlRequest];}- (BOOL)connectionShouldUseCredentialStorage:(NSURLConnection *)connection;{    return NO;}

如您所知，UIWebView不会提供与服务器通信的机会。我以这种方式解决了这个问题：在UIWebView的委托方法shouldStartLoadWithRequest中，我发起了另一个与NSURLConnection的连接，而在委托NSURLConnection的方法中，didReceiveAuthenticationChallenge已经处理了来自服务器的挑战。在方法didReceiveResponse中（如果挑战来了），然后再次在同一UIWebView中加载相同的URL（挑战已被处理：）。不要忘记在didReceiveResponse中取消连接，否则它将使流量增加一倍。
