ios https请求怎么忽略证书

Answer 1

　　使用一个私有API可以忽略证书无效等问题

　　[NSURLRequest setAllowsAnyHTTPSCertificate:YES forHost:[url host]];注意这是一个私有API，使用这个代码的APP将会被苹果商店拒绝。

　　另提供2个合法的方式，NSURLConnectionDelegate的

　　- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace

　　- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge

　　实例代码：

　　-(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([trustedHosts containsObject:challenge.protectionSpace.host]) [challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge]; [challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];}如果使用web view来请求网页的话，添加这么一句[NSURLConnection connectionWithRequest:request delegate:self];
