AFNetworking 2.0添加头到GET请求

我刚刚开始使用AFNetworking 2.0，我想知道如何将标题放入HTTP Get请求中。 文档build立一个像这样的GET：

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; NSDictionary *parameters = @{@"foo": @"bar"}; [manager POST:@"http://example.com/resources.json" parameters:parameters success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }]; 

但由于我们没有处理NSURLRequests我不知道如何设置HTTP头。

任何帮助，将不胜感激。
问候，

AFNetworking 2.0的梦幻般的文档使这个有点难找，但它在那里。 在AFHTTPRequestSerializer是-setValue:forHTTPHeaderField:

另外，如果你按照他们推荐的方法创build一个派生自AFHTTPSessionManager的会话pipe理器，那么这个类可以重写一个方法来修改每个请求上的-dataTaskWithRequest:completionHandler: 我使用它来检查请求，并在个案的基础上修改头文件，并且更喜欢修改序列化程序，因为它保持了pipe理程序中包含的networking连接的责任（并避免使用单例）

 - (NSURLSessionDataTask *)dataTaskWithRequest:(NSURLRequest *)request completionHandler:(void (^)(NSURLResponse *, id, NSError *))completionHandler { static NSString *deviceId; if(!deviceId) { deviceId = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; } NSMutableURLRequest *req = (NSMutableURLRequest *)request; // Give each request a unique ID for tracing NSString *reqId = [NSString stringWithFormat:@"%@+%@", deviceId, [[NSUUID UUID] UUIDString] ]; [req setValue:reqId forHTTPHeaderField:"x-myapp-requestId"]; return [super dataTaskWithRequest:req completionHandler:completionHandler]; } 

Answer 2

这是一个使用AFNetworking 2.0的例子

 AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.responseSerializer = [AFJSONResponseSerializer serializer]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; [manager.requestSerializer setValue:@"calvinAndHobbesRock" forHTTPHeaderField:@"XI do what I want"]; [manager GET:@"http://localhost:3000" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) { NSLog(@"JSON: %@", responseObject); } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", error); }]; 

关键是以下两行：

 manager.requestSerializer = [AFJSONRequestSerializer serializer]; [manager.requestSerializer setValue:@"calvinAndHobbessRock" forHTTPHeaderField:@"XI-do-what-I-want"]; 

Answer 3

添加响应和请求序列化器解决了我的问题。

 manager.responseSerializer = [AFJSONResponseSerializer serializer]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; 

Answer 4

我用这个表格来预约一个特定的标题。

 AFHTTPRequestOperationManager *operationManager = [AFHTTPRequestOperationManager manager]; [operationManager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [operationManager.requestSerializer setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; [operationManager POST:url parameters:params success:^(AFHTTPRequestOperation *operation, id responseObject) { if (success) { success(responseObject); } } failure:^(AFHTTPRequestOperation *operation, NSError *error) { NSLog(@"Error: %@", [error description]); } ]; 

Answer 5

这是我认为是最好的select。 在某个单例中，使用NSURLSessionConfigurationconfigurationNSURLSessionConfiguration ，然后在每次发出请求时使用该AFHTTPSessionManager 。

 NSURLSessionConfiguration *config = [NSURLSessionConfiguration defaultSessionConfiguration]; config.HTTPAdditionalHeaders = @{@"Accepts": @"application/json"}; mySingletonSessionManager = [[AFHTTPSessionManager alloc] initWithBaseURL:[NSURL URLWithString:kMyBaseUrl] sessionConfiguration:config]; 

Answer 6

我为…做了这些传递令牌的人

 [manager.requestSerializer setValue:[NSString stringWithFormat:@"Token token=\"%@\"", _userObj.oAuth] forHTTPHeaderField:@"Authorization"]; 

Answer 7

使用下面的代码来放置任何types的标题值：

 [[FRHTTPReqManager sharedManager].requestSerializer setValue:value forHTTPHeaderField:key];
