ios中http 和https 協議的存取碼

最近做個項目，開始採用的是HTTP協議實現用戶端和伺服器端的互動，後來需要改成HTTPS協議。在修改的過程中發現了一些問題，解決方案如下：

代碼如下

複製代碼

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

{     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];

//佈建要求方式為get

[request setHTTPMethod:@"GET"];     //添加使用者會話id     [request addValue:@"text/html" forHTTPHeaderField:@"Content-Type"];     //串連發送請求     finished = false;     NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:request delegate:self]; //堵塞線程，等待結束 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; } //下面兩段是重點，要伺服器端單項HTTPS 驗證，iOS 用戶端忽略認證驗證。 - (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]; } //處理資料 - (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { }
