iOS9苹果将原http协议改成了https协议的方法
解决方法:
在info.plist 加入key
<key>NSAppTransportSecurity</key> <dict> <key>NSAllowsArbitraryLoads</key> <true/> </dict>
下面给大家介绍ios中http 和https 协议的访问
最近做个项目,开始采用的是HTTP协议实现客户端和服务器端的交互,后来需要改成HTTPS协议。在修改的过程中发现了一些问题,解决方案如下:
HTTP:
NSString *urlString =[NSString stringWithFormat:@"https://127.0.0.1/default.aspx?USER=%@",@"111"]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:urlString]]; [request setHTTPMethod:@"GET"]; NSHTTPURLResponse* urlResponse = nil; NSError *error = [[NSError alloc] init]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSMutableString *result = [[NSMutableString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; NSLog(@"The result string is :%@",result);
HTTPS
事件触发
{ NSString *urlString =[NSString stringWithFormat:@"https://127.0.0.1/default.aspx?USER=%@",@"111"]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:urlString] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:5]; //设置请求方式为get [request setHTTPMethod:@"GET"]; //添加用户会话id [request addValue:@"text/html" forHTTPHeaderField:@"Content-Type"]; //连接发送请求 finished = false; NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self]; //堵塞线程,等待结束 while(!finished) { [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate distantFuture]]; } } - (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse*)response {} - (void)connectionDidFinishLoading:(NSURLConnection *)connection { //[_waitingDialog dismissWithClickedButtonIndex:0 animated:NO]; [connection release]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { } - (BOOL)connectionShouldUseCredentialStorage:(NSURLConnection *)connection{ return NO; } //下面两段是重点,要服务器端单项HTTPS 验证,iOS 客户端忽略证书验证。 - (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace { return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]; } - (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { NSLog(@"didReceiveAuthenticationChallenge %@ %zd", [[challenge protectionSpace] authenticationMethod], (ssize_t) [challenge previousFailureCount]); if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]){ [[challenge sender] useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; [[challenge sender] continueWithoutCredentialForAuthenticationChallenge: challenge]; } } NSLog(@"get the whole response"); //[receivedData setLength:0]; } //处理数据 - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { }
