嗨,我有以下访问URL的代码:

NSString * stringURL = [NSString stringWithFormat:@"%@/%@/someAPI", kSERVICE_URL, kSERVICE_VERSION];
NSURLRequest * request = [NSURLRequest requestWithURL:[NSURL URLWithString:stringURL]];

AFJSONRequestOperation * operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    completionHandler(JSON, nil);
} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    completionHandler(nil, error);
}];

但我想将用户令牌作为参数传递HEADER,如X-USER-TOKEN.

无法找到它AFNetworking documentation,我应该更改操作类型吗？
