AFNetworking 4.0 如何在 POST 请求中添加 headers？

Question

我这样做是为了在 AFNetworking 4.0

中定义 headers

      NSMutableDictionary *headers = [[NSMutableDictionary alloc]init];
      [headers setValue:[NSString stringWithFormat:@"Bearer %@",[defaults valueForKey:@"Token"]]  forKey:@"Authorization"];
      [manager POST:[NSURL URLWithString:path].absoluteString parameters:parameter headers:headers progress:nil success:^(NSURLSessionTask *task, id responseObject)
         { 

          }

这是AFNetworking 4.0

中定义的新POST方法

    - (NSURLSessionDataTask *)dataTaskWithHTTPMethod:(NSString *)method
                                   URLString:(NSString *)URLString
                                  parameters:(nullable id)parameters
                                     headers:(nullable NSDictionary <NSString *, NSString *> *)headers
                              uploadProgress:(nullable void (^)(NSProgress *uploadProgress)) uploadProgress
                            downloadProgress:(nullable void (^)(NSProgress *downloadProgress)) downloadProgress
                                     success:(nullable void (^)(NSURLSessionDataTask *task, id _Nullable responseObject))success
                                     failure:(nullable void (^)(NSURLSessionDataTask * _Nullable task, NSError *error))failure
     { 

      }

在执行此操作时显示错误“[<__NSDictionary0 0x10c62a870> setValue:forUndefinedKey:]：此 class 不是密钥授权的密钥值 coding-compliant。 “

请告诉我正确的解决方案。

提前致谢。

Answer 1

我现在使用 AFN 4.0，但我也在管理器上添加 header，如下所示：

AFHTTPSessionManager *sessionManager = [AFHTTPSessionManager manager];    
[sessionManager.requestSerializer setValue:bearerToken forHTTPHeaderField:@"Authorization"];

and GET/POST/PUT/DELETE header I send @{} to backend

希望能帮到你

使用此块方法

+(void)postServiveCall:(NSDictionary *)perameters headers:(NSArray *)headers WithSuccess:(void (^)(id responseObject))success failure:(void (^)( NSError *error))failure
{

   AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

   if(headers.count > 0)
   {
    for (NSDictionary *headerData in headers)
    {
        [manager.requestSerializer setValue:headerData.allValues.firstObject forHTTPHeaderField:headerData.allKeys.firstObject];
    }
   }
   AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
   responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"application/json", @"text/json", @"text/javascript", @"text/html", nil];

   manager.responseSerializer = responseSerializer;

   NSString *url = [NSString stringWithFormat:@"%@action.php",BASEURL];

   [manager POST:url parameters:perameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
    success (responseObject);
} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
    failure (error) ;

 }];
}

如何使用下面给出，如果需要，您可以在这里添加多个header字段

NSDictionary *postparam = @{@"action":@"versionCode",
                          @"version":version,@"device_type":@"iOS"
                          };

NSArray *heder = @[@{@"Authorization":[NSString stringWithFormat:@"Bearer %@",[defaults valueForKey:@"Token"]]}];

[ServiceCalls postServiveCall:postparam headers:heder WithSuccess:^(id responseObject)
 {
} failure:^(NSError *error)
{
}];

从上面给出的答案中，我找到了答案的中途。感谢@baiyidjp 和@Silversky Technology

的回复

     AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
     [manager setRequestSerializer:[AFHTTPRequestSerializer serializer]];

     NSString *path=[[NSString alloc]initWithFormat:@"%@",URL];

     NSMutableDictionary *parameter = [[NSMutableDictionary alloc]init];
     [parameter setValue:@"123456" forKey:@"id"];

     NSDictionary *headers = @{@"Authorization":[NSString stringWithFormat:@"Bearer %@",[defaults valueForKey:@"ApiToken"]]};

      [manager POST:[NSURL URLWithString:path].absoluteString parameters:parameter headers:headers progress:nil success:^(NSURLSessionTask *task, id responseObject)
         {
          NSLog(@"Response Object response is....==%@",responseObject);
          }
              failure:^(NSURLSessionTask *operation, NSError *error)
         {
          NSLog(@"Error Last 2 Done: %@", [error localizedDescription]);
          }
