Question

我正在使用RESTKit来实现GET请求，并且我希望有一个自定义的http标头。为了让GET请求获得所需的数据，我需要在头文件中发送一个令牌（作为变量）。但是，当我在控制台中查看响应时，它会给我一个401状态代码，这意味着该网站没有获得自定义http标头。我究竟做错了什么导致自定义标头无效。

这是我的代码：

NSIndexSet *statusCodeSet = RKStatusCodeIndexSetForClass(RKStatusCodeClassSuccessful);
    NSString *urlString = [NSString stringWithFormat:@"https://foo.com/foo/:foo_number/providers/find?name=%@&location=%@", nameIDTextField.text, locationTextField.text];
    NSURL *url = [NSURL URLWithString:urlString];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    //Here is my custom header code
    RKObjectManager *objectManager = [RKObjectManager managerWithBaseURL:url];
    [objectManager.HTTPClient setDefaultHeader:@"Auth-Token" value:[[self userAuthTokenMethod] userAuthToken]];
    //End of custom header code

    NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
    NSLog(@"Stuff Here ==> %@", connection);
    RKResponseDescriptor *responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:[MappingProvider tokenMapping]
                                                                                       pathPattern:@"/v2/styles"
                                                                                           keyPath:@"data"
                                                                                       statusCodes:statusCodeSet];
    NSURLRequest *doctorRequest = [NSURLRequest requestWithURL:url];
    RKObjectRequestOperation *operation = [[RKObjectRequestOperation alloc] initWithRequest:doctorRequest
                                                                        responseDescriptors:@[responseDescriptor]];
    [operation setCompletionBlockWithSuccess:^(RKObjectRequestOperation *operation, RKMappingResult *mappingResult)
    {
        NSLog(@"Mapping Results ==> %@", mappingResult.array);
    }
    failure:^(RKObjectRequestOperation *operation, NSError *error)
    {
        NSLog(@"ERROR: %@", error);
        NSLog(@"Response: %@", operation.HTTPRequestOperation.responseString);
    }];

    [operation start];

编辑：

以下是错误日志的一部分：

2013-08-01 22:42:58.547 Empyrean[78461:5803] E restkit.network:RKObjectRequestOperation.m:576 Object request failed: Underlying HTTP request 
operation failed with error: Error Domain=org.restkit.RestKit.ErrorDomain Code=-1011 "Expected status code in (200-299), got 401"

如果您发现代码有任何其他问题，请随时指出。

Answer 1

问题是您正在对象管理器HTTP客户端上设置标头，然后不使用对象管理器，因为您正在显式创建URL请求，然后执行运行它的操作。选择2个选项中的1个并坚持下去。如果您自己创建请求，则还需要向其添加标题。

Answer 2

您可以使用NSMutableURLRequest这样最容易解决您的401问题：

    NSMutableURLRequest *doctorRequest = [NSMutableURLRequest requestWithURL:url];
    [doctorRequest setValue:[[self userAuthTokenMethod] userAuthToken] forHTTPHeaderField:@"Auth-Token"];

除此之外：request，objectManager和connection对象并未真正用于代码的那一部分。当你尝试使用objectManager时，最好为所有请求默认设置头字段。但是，您需要获取objectManager的HTTPClient来为您创建请求。
