如何使用客户端证书对 UIWebView 进行身份验证？

Question

我有以下问题：

我有一个 UIWebView 可以正确加载网站，但服务器也需要来自客户端 (UIWebView) 的身份验证。我已经使用从另一个站点获得的以下代码添加了 ssl certificate：

shouldStartLoadWithRequest:

-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType (UIWebViewNavigationType)navigationType;
{
    if(![self authenticated])
    {
        [self setAuthenticated:NO];
        [self setUrlConnection:[[NSURLConnection alloc] initWithRequest:[self requestObj] delegate:self]];
        [[self urlConnection] start];
        return NO;
    }
    return YES;
}

didReceiveAuthenticationChallenge:

-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
    if ([challenge previousFailureCount] == 0)
    {
        [self setAuthenticated:YES];
        NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];
        [challenge.sender useCredential:credential forAuthenticationChallenge:challenge];
    }
    else [[challenge sender] cancelAuthenticationChallenge:challenge];
}

didReceiveResponse:

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response;
{
    [self setAuthenticated:YES];
    [[self webView] loadRequest:[self requestObj]];
    [[self urlConnection] cancel];
}

canAuthenticateAgainstProtectionSpace:

-(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace
{
    return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}

现在服务器需要来自具有特定 DN 名称的客户端（证书）的身份验证。我找到 iOS Client Certificates and Mobile Device Management 但代码没有帮助我，也没有解决我的问题。

是否可以将 PKCS12 文件附加到我的 UIWebView，这样如果服务器需要来自客户端的身份验证，UIWebView 会向他显示此文件吗？

我总是得到错误

2016-04-20 12:20:50.880 App [469:126255] NSURLSession/NSURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)

Answer 1

使用这段代码

-(void)connection:(NSURLConnection *)connection willSendRequestForAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {

if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
{
    NSURL* baseURL = [NSURL URLWithString:SERVER_IP];
    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];
}

并将此 class 添加到当前 class

的上方

@interface NSURLRequest(AllowAllCerts)

@end


@implementation NSURLRequest(AllowAllCerts)

+ (BOOL)allowsAnyHTTPSCertificateForHost:(NSString *)host
{

return YES;

}
@end
