ios - NSMutableURLRequest 设置授权头

Question

当设置 NSMutableURLRequest 的“授权” header 时，我的服务器对 header 的响应不包括该 header :

[Host] => myhost.com
[Content-Type] => application/x-www-form-urlencoded
[Connection] => keep-alive
[Accept] => */*
[User-Agent] => MyApp/1 CFNetwork/758.3.15 Darwin/15.4.0
[Content-Length] => 327
[Accept-Language] => en-gb
[Accept-Encoding] => gzip, deflate

我阅读了文档建议不要在这里设置它，那么我应该在哪里设置客户端的授权 header ？

我的目的 Authorization header 是发送我的 Oauth 签名和其他 Oauth 相关信息

你有用户和密码 API

 // Create the request
 NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:0];

// New Create the connection
NSURLSessionConfiguration *defaultConfigObject = [NSURLSessionConfiguration defaultSessionConfiguration];

NSURLSession *session = [NSURLSession sharedSession];//sessionWithConfiguration:defaultConfigObject delegate:self delegateQueue:[NSOperationQueue mainQueue]];

NSURLCredential *creds = [NSURLCredential credentialWithUser:self.username password:self.password persistence:NSURLCredentialPersistenceForSession];

NSString *authStr = [NSString stringWithFormat:@"%@:%@",self.username,self.password];// @"username:password";

NSData *authData = [authStr dataUsingEncoding:NSUTF8StringEncoding];

NSString *authValue = [NSString stringWithFormat: @"Basic %@",[authData base64EncodedStringWithOptions:0]];

// Part Important
[request setValue:authValue forHTTPHeaderField:@"Authorization"];

// Or Token
 NSString *authValueToken = @"OAuth UElJRFER1A5zcGkyW16T0";
 [request setValue:authValueToken forHTTPHeaderField:@"AuthenticatedToken"];// Authenticated API


NSString *postLength = [NSString stringWithFormat:@"327"];
[request setValue:postLength forHTTPHeaderField:@"Content-Length"];

NSString *postLength = [NSString stringWithFormat:@"application/x-www-form-urlencoded"];
[request setValue:postLength forHTTPHeaderField:@"Content-Type"];

NSURLSessionDataTask *dataTask = [session dataTaskWithRequest:request     
    completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
           receivedData = [NSMutableData data];
           NSString* responseData = [[NSString alloc] initWithData:data encoding: NSUTF8StringEncoding];
           NSLog(@"%@",responseData);
           if (error) {
                   [self handleError: error];
           }
 }];

[dataTask resume]; // <- important

NSLog(@"Header Fields Request--->> %@",request.allHTTPHeaderFields);
