Question

我正在尝试使用iOS 9+中的UIWebView加载 https：// 网页并且它给出了以下错误：

NSURLSession / NSURLConnection HTTP加载失败（kCFStreamErrorDomainSSL，-9802）CFNetwork SSLHandshake失败（-9802）

我已经尝试了各种使用NSURLConnection首先使用connection:willSendRequestForAuthenticationChallenge:方法处理身份验证质询的方法。

虽然这适用于直接请求，但是 （此处实际问题已经开始）如果网页重定向到具有不同域的其他网页，则无效

例如，最初我通过调用 UIWebView 加载https://example.com，然后此页面重定向到 https://someothersecuredomain.com 。这是连接失败并且未调用connection:willSendRequestForAuthenticationChallenge:。

以下是我的实施：

- (void)viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];

    // Load webview with request url and parameters
    NSMutableURLRequest* request = [[NSMutableURLRequest alloc] initWithURL:url];
    [request setHTTPBody:postBody];
    [request setHTTPMethod: @"POST"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];

    self.webView.delegate = self;
    [self.webView loadRequest: request];

    _BaseRequestURL = url;
}

#pragma mark UIWebView delegate
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {

    if (![[request.URL absoluteString] isEqualToString:[_FailedRequest.URL absoluteString]]) {

        _FailedRequest = request;
        (void)[[NSURLConnection alloc] initWithRequest:request delegate:self];
        return NO;
    }

    return YES;
}

#pragma mark - NSURLConnectionDataDelegate methods

-(void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
    if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {
        NSURL *baseURL = [_FailedRequest URL];
        if ([challenge.protectionSpace.host isEqualToString:baseURL.host]) {
            NSLog(@"trusting connection to host %@", challenge.protectionSpace.host);
            [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
        } else
            NSLog(@"Not trusting connection to host %@", challenge.protectionSpace.host);
    }
    [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)pResponse {

    [connection cancel];
    [self.webView loadRequest:_FailedRequest];
}

- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {

    NSLog(@"connection error : %@", error);
}

这是记录的连接错误：

错误域= NSURLErrorDomain代码= -1200“发生了SSL错误并且无法与服务器建立安全连接。“ UserInfo = {NSUnderlyingError = 0x138643250 {错误 Domain = kCFErrorDomainCFNetwork Code = -1200“发生了SSL错误并且无法与服务器建立安全连接。“ 的UserInfo = {NSErrorFailingURLStringKey = https://secure.ccavenue.com/transaction/transaction.do?command=initiateTransaction， NSLocalizedRecoverySuggestion =您想要连接到服务器吗？无论如何？，_kCFNetworkCFStreamSSLErrorOriginalValue = -9802， _kCFStreamPropertySSLClientCertificateState = 0，NSLocalizedDescription =发生了SSL错误并且安全无法建立与服务器的连接。，_ kCFStreamErrorDomainKey = 3， NSErrorFailingURLKey = https://secure.ccavenue.com/transaction/transaction.do?command=initiateTransaction， _kCFStreamErrorCodeKey = -9802}}，NSErrorFailingURLStringKey = https://secure.ccavenue.com/transaction/transaction.do?command=initiateTransaction， NSErrorFailingURLKey = https://secure.ccavenue.com/transaction/transaction.do?command=initiateTransaction， NSLocalizedRecoverySuggestion =您想要连接到服务器吗？无论如何？，NSLocalizedDescription =发生了SSL错误并且是安全的无法连接到服务器。}

根据iOS 9的应用传输安全性，我已将这两个域添加到我的Info.plist中的例外域列表中。

这是这样的：

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSAllowsArbitraryLoads</key>
    <false/>
    <key>NSExceptionDomains</key>
    <dict>
        <key>example.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
        </dict>
        <key>secure.ccavenue.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
            <true/>
            <key>NSTemporaryExceptionMinimumTLSVersion</key>
            <string>TLSv1.1</string>
        </dict>
    </dict>
</dict>

我真的被困在这里，任何帮助都会受到赞赏。
