我希望我的应用程序针对设备进行身份验证,即通过 https 传递用户名和密码。
我看了几个例子,基本上构建了以下内容:
-(void)authentication
{
//setting the string of the url taking from appliance IP.
NSString *urlString =[NSString
stringWithFormat:
@"http://%@",appliance_IP.text];
//define the url with the string
NSURL *url = [NSURL URLWithString:urlString];
//creating request
NSURLRequest *request = [NSURLRequest requestWithURL:url];
//setting credential taking from the username and password field
NSURLCredential *credential = [NSURLCredential credentialWithUser:username.text password:password.text persistence:NSURLCredentialPersistenceForSession];
NSURLProtectionSpace *protectionSpace=
[[NSURLProtectionSpace alloc]initWithHost:urlString port:443 protocol:@"https" realm:nil authenticationMethod:nil ];
[[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:credential forProtectionSpace:protectionSpace];
[ NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL];
}
因为我使用的示例我需要更多理解,上面示例中的 NSURLConnection 不包含用户名和密码,我该如何添加?因此请求还将包含用户名和密码,或者传递该信息可能更好。 目前请求只包含url字符串。
谢谢 错误
最佳答案
当发出需要身份验证的请求时,您将收到 didReceiveAuthenticationChallenge 的回调,您的处理如下:
-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge
{
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
{
if ([challenge.protectionSpace.host isEqualToString:MY_PROTECTION_SPACE_HOST])
{
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust] forAuthenticationChallenge:challenge];
}
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}
else if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodHTTPBasic])
{
if ([challenge previousFailureCount] == 0)
{
NSURLCredential *newCredential;
newCredential = [NSURLCredential credentialWithUser:MY_USERNAME
password:MY_PASSWORD
persistence:NSURLCredentialPersistenceForSession];
[[challenge sender] useCredential:newCredential forAuthenticationChallenge:challenge];
}
else
{
[[challenge sender] cancelAuthenticationChallenge:challenge];
// inform the user that the user name and password
// in the preferences are incorrect
NSLog (@"failed authentication");
// ...error will be handled by connection didFailWithError
}
}
}
