使用 afnetworking 2.0 发送字典数组答案

【问题标题】：Sending array of dictionary with afnetworking 2.0使用 afnetworking 2.0 发送字典数组

【问题描述】：

我有一个大问题，我正在尝试使用 afnetworking 发送一个字典数组，这是我的代码：

checkDeliveryParams = @{@"cart_total":@(cart_total),@"shipping":@{@"address":[User  sharedInstance].shipping_city,@"country":@"IT",@"postcode":[User sharedInstance].shipping_postcode,@"state":[User sharedInstance].shipping_provincia},@"user_id":@([User sharedInstance].user_id),@"cart_contents":temp};

购物车总数是这样的数组

(
  quantity:1
  product_id:2

)

但是服务器收到类似这样的东西

(
quantity:1
),
(
product_id:2
)

我的请求代码是

+(void)GET:(NSString *)path
    params:(NSDictionary *)params
      auth:(BOOL)authenticate
   success:(void (^)(NSDictionary* responseObject))success
   failure:(void (^)(NSError *error, NSDictionary* responseObject))failure{
    
    
    NSString *URLString = [@"" stringByAppendingPathComponent:path];
    NSLog(@"GET - API URL: %@", URLString);
    
    AFHTTPRequestOperationManager *manager = [Rest commonManager:path sendAuthToken:authenticate];
  //  manager.requestSerializer=NSJSONSerialization ;
    [manager GET:URLString parameters:params success:^(AFHTTPRequestOperation *operation, NSDictionary *responsedata){
        NSLog(@"ok della richiesta %@",responsedata);
        [Rest verbose:responsedata];
        success(responsedata);
        
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"errore della richiesta %@",error.localizedDescription);
        failure(error,[Rest parseErrorResponseForOperation:operation]);
        
    }];
    
}

试过很多方法，试过设置nsjonserializer，"application/json"，试过用NSURLSessionDataTask...

对不起我的英语，有人可以帮助我吗？

[rest commonManager] 中的公共管理器调用在此方法中定义

+(AFHTTPRequestOperationManager *)commonManager:(NSString *)path sendAuthToken:(BOOL)sendToken{
    
    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    manager.responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];

    manager.securityPolicy.allowInvalidCertificates = NO;
    
    manager.requestSerializer = [AFJSONRequestSerializer serializer];
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Accept"];

    
    
    if([Session isOpen] && [Rest authorizationRequiredForPath:path] && sendToken){
        [manager.requestSerializer setValue:[NSString stringWithFormat:@"Bearer %@", [Session token]] forHTTPHeaderField:@"Authorization"];
    }
    
    return manager;
}

【问题讨论】：

cart_total 很奇怪。你能澄清一下它的价值吗？因为quantity:1，那是什么？一个字符串？ “键/值”字典？你的NSLog(@"Cart Total: %@", cart_total)可以吗？
对不起，我错了，数组是购物车内容而不是购物车总数
不清楚。你能做NSData *jsonData = [NSJSONSerialization jsonDataWithObject: checkDeliveryParams options: 0 error: nil]; NSLog(@"JSON Sending: %@", [[NSString alloc] initWithData: jsonData]) 并给出输出吗？
JSON 发送：{"cart_contents":[{"product_id":10155,"quantity":1},{"product_id":17960,"quantity":1}],"user_id": 91,"shipping":{"country":"IT","state":"PA","city":"palermo","postcode":"90124","address":"via giovanni gentile 3"} ,"cart_total":119.30000305175781}
但是服务器没有收到这种格式的，为什么？

【解决方案1】：

这就是我在 get 调用中发送参数的方式

+(void)GET:(NSString *)path
    params:(NSDictionary *)params
      auth:(BOOL)authenticate
   success:(void (^)(NSDictionary* responseObject))success
   failure:(void (^)(NSError *error, NSDictionary* responseObject))failure{
    
    
    NSString *URLString = [@"" stringByAppendingPathComponent:path];
    NSLog(@"GET - API URL: %@", URLString);
    
    AFHTTPRequestOperationManager *manager = [Rest commonManager:path sendAuthToken:authenticate];
  //  manager.requestSerializer=NSJSONSerialization ;
    [manager GET:URLString parameters:params success:^(AFHTTPRequestOperation *operation, NSDictionary *responsedata){
        NSLog(@"ok della richiesta %@",responsedata);
        [Rest verbose:responsedata];
        success(responsedata);
        
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"errore della richiesta %@",error.localizedDescription);
        failure(error,[Rest parseErrorResponseForOperation:operation]);
        
    }];
    
}
