如何在uiwebview中调用https url？

我有一个HTTPSurl。 它在iPhone Safari中加载，但在UIWebView不起作用。

错误是：

NSURLConnection / CFURLConnection HTTP加载失败（kCFStreamErrorDomainSSL，-9813）

我该如何解决这个问题？

我已经在下面解释了如何在UIWebview中访问https url，它将帮助你清除这个问题，因为它适用于我。

调用http与https url相同。

但是，如果您使用的是自签名证书 ，则需要添加一些附加代码。因为默认情况下，iOS会拒绝所有不受信任的https连接。

限制不信任的连接是非常好的默认行为，任何禁用这个都是非常危险的。所以我们将显示一个警告，因为我们将绕过默认行为。

 -(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace; -(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge; 

以上两个方法允许我们为受信任的连接提供我们自己的authentication机制

 #import "ClassCon.h" // For now, I've hard coded the IP address of my trusted server. #define TRUSTED_HOST @"192.168.1.2" @implementation ClassCon { NSMutableData *contentData; NSURLConnection *conn; } -(void) loadContent { contentData = [NSMutableData data]; NSString *contentURL = @"our url"; conn = [[NSURLConnection alloc] initWithRequest: [NSURLRequest requestWithURL:[NSURL URLWithString:contentURL]] delegate:self]; } - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { [contentData appendData:data]; } - (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"Bad: %@", [error description]); ContentResponse *response = [[ContentResponse alloc]initWithRc:-999 andDescr:@"error" andAction:0]; conn = nil; } - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSString *loadedContent = [[NSString alloc] initWithData: contentData encoding:NSUTF8StringEncoding]; NSLog(@"Loaded content: %@",loadedContent); } // ------------ ByPass ssl starts ---------- -(BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace: (NSURLProtectionSpace *)protectionSpace { return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } -(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge: (NSURLAuthenticationChallenge *)challenge { if (([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])) { if ([challenge.protectionSpace.host isEqualToString:TRUSTED_HOST]) { NSLog(@"Allowing bypass..."); NSURLCredential *credential = [NSURLCredential credentialForTrust: challenge.protectionSpace.serverTrust]; [challenge.sender useCredential:credential forAuthenticationChallenge:challenge]; } } [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge]; } // -------------------ByPass ssl ends @end 

希望这可以帮助
