ios - 具有授权的 UIWebView，单击链接时使用相同的身份验证

Question

我有一个 UIWebView，它使用此代码使用基本授权导航到网页

NSString *authValue = [NSString stringWithFormat:@"Basic %@", AFBase64EncodedStringFromString(basicAuthCredentials)];
    [urlRequest setValue:authValue forHTTPHeaderField:@"Authorization"];

现在当一个链接被点击时，webView 的 shouldStartLoadWithRequest 被触发但是页面没有加载，因为下一个页面也需要授权。

有没有办法自动为点击的链接添加授权？

谢谢

如何在 shouldStartLoad 中正确创建新请求

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
    BOOL shouldNavigate = NO;
    NSString *existingAuthValue = [request valueForHTTPHeaderField:@"Authorization"];
    if (existingAuthValue == nil)
    {
        NSString *authValue = [NSString stringWithFormat:@"Basic %@", AFBase64EncodedStringFromString(basicAuthCredentials)];
        [request setValue:authValue forHTTPHeaderField:@"Authorization"];
        NSMutableURLRequest *newRequest = [NSMutableURLRequest requestWithURL:request.URL];
        //Append any other info from the old request
        [webView performSelector:@selector(loadRequest:) withObject:newRequest afterDelay:0];
    }
    else
    {
        shouldNavigate = YES;
    }
    return shouldNavigate;
}

编辑:抱歉，我没有考虑到 NSURLRequest != NSMutableURLRequest。我会更新代码。
