如何使用一个 NSURL 向 Web 服务器发出多个经过身份验证的请求

Question

我想从 http://mycompany.com/jsonpage1..etc 获取JSON。网络服务器需要初始登录 http://mycompany.com/login，然后为用户维护cookie。如何使用 NSURLCredentialStorage 获取此行为，而无需每次都要求登录？这是使用 NSURLCredential Storage 的非工作代码

- (IBAction)getJSON:(id)sender
{
//  [self establishSession];
NSURLCredential *credential = [NSURLCredential credentialWithUser:@"user"
                                                         password:@"pass"
                                                          persistence:NSURLCredentialPersistenceForSession];
NSURLProtectionSpace *protectionSpace = [[NSURLProtectionSpace alloc]
                                         initWithHost:@"myCompany.com"
                                         port:0
                                         protocol:@"http"
                                         realm:nil
                                         authenticationMethod:nil];
[[NSURLCredentialStorage sharedCredentialStorage] setDefaultCredential:credential
                                                    forProtectionSpace:protectionSpace];

//////////GET JSON//////////////
NSError *error;
NSURL *url = [NSURL URLWithString:@"http://mycompany.com.jsonpage1"];
 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
}
 //I am NOT getting JSON in this delegate
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSString *responseString = [[NSString alloc] initWithData:responseData    encoding:NSUTF8StringEncoding];
NSLog(@"%@",responseString);
}

您可以尝试AFNetworking库和子类AFHTTPClient，您可以在其中封装每个请求的身份验证。
