iphone-使用 CFNetwork API 使用自签名证书连接到 https url

Question

简而言之，我的问题是我尝试使用 NSURLConnection 类及其委托方法连接到 https url。

我收到“发生 SSL 错误，无法与服务器建立安全连接”错误

所以我实现了 这个解决方案。但运气不佳。解决方案中指定的委托方法永远不会被调用。

只

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

被调用并出现上述错误

所以我转而使用 CFNetwork API 通过自签名证书连接到 https url

这是我的代码。我从 此处 和 CFNetwork 编程指南 来自 Apple

CFReadStreamRef readStream;
            CFHTTPMessageRef request;

            CFStringRef requestMessage = (CFStringRef)postparameters;

            request = CFHTTPMessageCreateRequest(kCFAllocatorDefault, CFSTR("POST"),
                                                 (CFURLRef) postURL, kCFHTTPVersion1_1);


            CFHTTPMessageSetBody(request, (CFDataRef) requestMessage);
            readStream = CFReadStreamCreateForHTTPRequest(kCFAllocatorDefault, request);
            CFRelease(request);

            NSDictionary *settings = [[NSDictionary alloc] initWithObjectsAndKeys:
                                      [NSNumber numberWithBool:YES], kCFStreamSSLAllowsExpiredCertificates,
                                      [NSNumber numberWithBool:YES], kCFStreamSSLAllowsAnyRoot,
                                      [NSNumber numberWithBool:NO], kCFStreamSSLValidatesCertificateChain,
                                      kCFNull,kCFStreamSSLPeerName,
                                      nil];

            CFReadStreamSetProperty((CFReadStreamRef)readStream, kCFStreamPropertySSLSettings, (CFTypeRef)settings);

            CFReadStreamOpen(readStream);

            /* Add to the run loop */
            CFReadStreamScheduleWithRunLoop(readStream, CFRunLoopGetCurrent(),
                                            kCFRunLoopCommonModes);

            if (!CFReadStreamOpen(readStream)) {
            DLog(@"method called");
            [_progressAlert dismissWithClickedButtonIndex:0 animated:YES];
            CFReadStreamSetClient(readStream, 0, NULL, NULL);
            CFReadStreamUnscheduleFromRunLoop(readStream,
                                              CFRunLoopGetCurrent(),
                                              kCFRunLoopCommonModes);
            CFRelease(readStream);
        }
        else {
        CFHTTPMessageRef myResponse =
        (CFHTTPMessageRef)CFReadStreamCopyProperty(readStream,
                                                   kCFStreamPropertyHTTPResponseHeader);
        //You can get the complete status line from the response message by calling the function CFHTTPMessageCopyResponseStatusLine:
        CFStringRef myStatusLine = CFHTTPMessageCopyResponseStatusLine(myResponse);
        DLog(@"status: %@", (NSString *)myStatusLine);

        UInt32 myErrCode = CFHTTPMessageGetResponseStatusCode(myResponse);
        NSLog(@"error :%lu", myErrCode);
        }

输出 i在控制台中看到的是

2011-11-30 21:02:07.720 [3800:f803][Line 180] method called

我需要添加到上面的代码中才能使其工作。

我猜这与身份验证有关。

请帮我一些示例代码。

更新：我更新了上面的代码，response.My !CFReadStreamOpen(readStream) 方法返回 true 并且打印日志
