afnetworking 3.0迁移：如何使用标题和HTTP正文进行POST

我试图做一个POST请求有HTTPHeader字段和HTTP正文的YouTube的API。

以前在AFNetworking 2.0版中，我曾经这样做过，

NSDictionary *parameters = @{@"snippet": @{@"textOriginal":self.commentToPost.text,@"parentId":self.commentReplyingTo.commentId}}; NSString *url = [NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/comments?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url]]; [request setHTTPMethod:@"POST"]; [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parameters options:0 error:&error]; NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]; // And finally, add it to HTTP body and job done. [request setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager]; manager.requestSerializer.timeoutInterval=[[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; AFHTTPRequestOperation *operation = [manager HTTPRequestOperationWithRequest:request progress:nil success:^(NSURLSessionTask *task, id responseObject) { NSLog(@"Reply JSON: %@", responseObject); } } failure:^(NSURLSessionTask *operation, NSError *error) { NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request); }]; [operation start]; 

3.0版的迁移文档用AFHTTPRequestOperationManagerreplaceAFHTTPRequestOperationManager但是我似乎无法findAFHTTPSessionManager的HTTPRequestOperationWithRequest方法。

我尝试使用constructingBodyWithBlock但它不工作，也许是因为我没有正确地做。

这是我迄今为止不起作用的：

 NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}}; NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error]; NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]; AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; AFJSONRequestSerializer *serializer = [AFJSONRequestSerializer serializer]; serializer.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue]; [serializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [serializer setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [manager POST:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> _Nonnull formData) { [formData appendPartWithHeaders:nil body:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; } progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { NSLog(@"Reply JSON: %@", responseObject); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"Error: %@, %@, %@, %@, %@", error, operation.responseObject, operation.responseData, operation.responseString, operation.request); }]; 

Answer 1

与AFNetworking 3.0调用POST方法的另一种方法是：

 AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc]initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; manager.requestSerializer = [AFJSONRequestSerializer serializer]; [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [manager POST:url parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { NSLog(@"success!"); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"error: %@", error); }]; 

希望能帮助到你！

Answer 2

我能够自己弄清楚这一点。

这是解决scheme。

首先，您需要首先从AFJSONRequestSerializer创buildNSMutableURLRequest ，您可以在其中将方法types设置为POST。

在这个请求中，你设置了你的HTTPHeaderFields后，你就可以设置HTTPHeaderFields 。 确保在为内容types设置Header字段后设置主体，否则api将给出400错误。

然后在pipe理器上使用上面的NSMutableURLRequest创build一个dataTaskWithRequest 。 不要忘记在最后resume dataTask，否则什么都不会发送。 这是我的解决scheme代码，希望有人能成功地使用它：

 NSDictionary *body = @{@"snippet": @{@"topLevelComment":@{@"snippet":@{@"textOriginal":self.commentToPost.text}},@"videoId":self.videoIdPostingOn}}; NSError *error; NSData *jsonData = [NSJSONSerialization dataWithJSONObject:body options:0 error:&error]; NSString *jsonString = [[NSString alloc] initWithData:jsonData encoding:NSUTF8StringEncoding]; AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; NSMutableURLRequest *req = [[AFJSONRequestSerializer serializer] requestWithMethod:@"POST" URLString:[NSString stringWithFormat:@"https://www.googleapis.com/youtube/v3/commentThreads?part=snippet&access_token=%@",[[LoginSingleton sharedInstance] getaccesstoken]] parameters:nil error:nil]; req.timeoutInterval= [[[NSUserDefaults standardUserDefaults] valueForKey:@"timeoutInterval"] longValue]; [req setValue:@"application/json" forHTTPHeaderField:@"Content-Type"]; [req setValue:@"application/json" forHTTPHeaderField:@"Accept"]; [req setHTTPBody:[jsonString dataUsingEncoding:NSUTF8StringEncoding]]; [[manager dataTaskWithRequest:req completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { if (!error) { NSLog(@"Reply JSON: %@", responseObject); if ([responseObject isKindOfClass:[NSDictionary class]]) { //blah blah } } else { NSLog(@"Error: %@, %@, %@", error, response, responseObject); } }] resume]; 

Answer 3

  -(void)postRequest:(NSString *)urlStr parameters:(NSDictionary *)parametersDictionary completionHandler:(void (^)(NSString*, NSDictionary*))completionBlock{ NSURL *URL = [NSURL URLWithString:urlStr]; AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; manager.responseSerializer = [AFHTTPResponseSerializer serializer]; [manager POST:URL.absoluteString parameters:parametersDictionary progress:nil success:^(NSURLSessionDataTask *task, id responseObject) { NSError* error; NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:&error]; completionBlock(@"Success",json); } failure:^(NSURLSessionDataTask *task, NSError *error) { NSLog(@"Error: %@", error); completionBlock(@"Error",nil); }]; } 

这种方法对AFNetworking 3.0工作正常。

Answer 5

使用常见的NSObject类方法调用与AFNetworking 3.0文件服务这是我的重复的答案，但它已被AFNetworking 3.0更新首先使NSObject类像Webservice.h和Webservice.m

Webservice.h

 @interface Webservice : NSObject + (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure; @end 

Webservice.m你的nsobject.m文件看起来像这样（ 在.m文件中添加两个函数 ）

 #import "Webservice.h" #define kDefaultErrorCode 12345 @implementation Webservice + (void)requestPostUrl:(NSString *)strURL parameters:(NSDictionary *)dictParams success:(void (^)(NSDictionary *responce))success failure:(void (^)(NSError *error))failure { AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; [manager setResponseSerializer:[AFHTTPResponseSerializer serializer]]; [manager POST:strURL parameters:dictParams progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id _Nullable responseObject) { if([responseObject isKindOfClass:[NSDictionary class]]) { if(success) { success(responseObject); } } else { NSDictionary *response = [NSJSONSerialization JSONObjectWithData:responseObject options:NSJSONReadingAllowFragments error:nil]; if(success) { success(response); } } } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { if(failure) { failure(error); } }]; } @end 

确保您必须将成功的字典密钥replace为处理响应callback函数的消息

使用像这样从任何viewControllers和任何viewControllers任何方法调用这个常用的方法。 暂时我使用viewDidLoad调用这个WS。

  - (void)viewDidLoad { [super viewDidLoad]; NSDictionary *dictParam = @{@"parameter1":@"value1",@"parameter1":@"value2"}; [Webservice requestPostUrl:@"add your webservice URL here" parameters:dictParam success:^(NSDictionary *responce) { //Success NSLog(@"responce:%@",responce); //do code here } failure:^(NSError *error) { //error }]; } 

在上面的方法中添加你的参数，值和web服务的URL。 你可以很容易地使用这个NSObjcet类。 欲了解更多详情，请访问AFNetworking 3.0或我的旧AFANSworking 2.0 answear 。
