iphone uiwebview身份验证挑战在登录时始终触发

Question

我最近通过iPhones UIWebView实现了身份验证挑战登录。我已经把它工作到了我受到挑战的地步，然后我提出了一个带有文本字段的提醒，然后将数据发送到需要身份验证的站点。

我还没有尝试过使用这个除了我的netgear路由器之外的其他东西。但我的问题是，当我浏览路由器的设置时，认证挑战被调用，因此即使用户登录也会显示警报。

下面是我使用的代码，任何建议都会感激理解

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType { 
NSLog(@"Did start loading: %@ auth:%d", [[request URL] absoluteString], _authed); 
myRequest=[request copy]; 

if (_authed) { 
    NSLog(@"_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 YES; 
} 
[[NSURLConnection alloc] initWithRequest:request delegate:self]; 
return YES;} 
- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { 
NSLog(@"protection space %@", protectionSpace.authenticationMethod); 
//if(![protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodDefault]){ 
return NO; 
//} 
//else{ 
// return YES; 
//} 

//[protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust] || [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodHTTPBasic];} 

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge;{NSLog(@"received response via nsurlconnection %@", connection); 

NSLog(@"got auth challange %@", challenge); 
UIApplication* app = [UIApplication sharedApplication]; 
app.networkActivityIndicatorVisible = NO; 
/*NSString *aarrgghh=[NSString stringWithFormat:@"%@",connection]; 
NSString *searchForMe = @"login"; 
NSLog (@"arrgghhh %@",aarrgghh); 
NSRange range = [aarrgghh rangeOfString:searchForMe];*/ 


if ([challenge previousFailureCount] <=1) { 

    //present alert with text fields for credentials 
} else { 
    [[challenge sender] cancelAuthenticationChallenge:challenge]; 
}} 

-(void)connection:(NSURLConnection *)connection didCancelAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge{ 
NSLog(@"Challenge cancelled");} 

//` - （无效）连接：（NSURLConnection的*）连接didReceiveData：（NSData的*）数据{ 的NSLog（@ “接收的数据”）; }

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;{ 
    NSLog(@"received response via nsurlconnection %@", response); 

    // THIS IS WHERE YOU SET MAKE THE NEW REQUEST TO UIWebView, which will use the new saved auth info 
    if(_authed){ 
    //NSURLRequest *urlRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:self.webView.request.URL.absoluteString]]; 

    [webView loadRequest:myRequest]; 
} 
}

可能做到这一点更简单的方法，但这对我来说是什么工作。

首先，当shouldStartLoadWithRequest返回YES，它告诉UIWebView创建NSURLConnection并为您运行它们。既然你不能分配一个委托给这个连接，这是行不通的。如果你想通过NSURLConnectionDelegate来处理认证，那么shouldStartLoadWithRequest应该总是为该UIWebView返回NO。

所以你需要自己处理连接。关火与请求的NSURLConnection和使用的NSURLConnection委托方法剩下来处理负载（例如保持MIME类型的轨道，并建立了一个NSMutableData）

最后，当你到connectionDidFinishLoading，您可以拨打UIWebView的loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)textEncodingName baseURL:(NSURL *)baseURL与NSData您的连接已下载。
