IOS开发中AFNetWorking3.0和MJExtention的组合使用

1、AFNetworking是IOS开发目前主流网络请求框架，目前最新发布的版本为3.0，对老版本用户可查看迁移指南，地址为：github.com/AFNetworking/AFNetworking/wiki/AFNetworking-3.0-Migration-Guide
2、MJExtention是字典转模型框架，当然还有其他字典转模型框架，只是这个国内开发者用的比较多。地址为：github.com/CoderMJLee/MJExtension
直接上代码直观展示最基础的功能(这里没有进一步解耦代码，初学者很好理解)

这里是服务器返回的Json数据格式：

{
  "meta": {
    "message": "登录成功！",
    "status_code": 200
  },
  "data": {
    "token": "eyJ0eXAiOiiOiJIUzI1NiJ9.sIm5iZiI6MTzkifQ.piS_YZhOqsjAF4XbxELIs2y70cq8",
  }
}

下面是模型的实现：
Login.h

#import 
@class Meta,Data;
@interface Login : NSObject
@property (nonatomic,strong) Meta* meta;
@property (nonatomic,strong) Data* data;
@end

@interface Meta : NSObject
@property (nonatomic,copy) NSString* message;
@property (nonatomic,assign) NSInteger status_code;
@end

@interface Data : NSObject
@property (nonatomic,copy) NSString* token;
@end

Login.m

#import "Login.h"
@implementation Login

@end

@implementation Meta

@end

@implementation Data

@end

这里简单发送一个POST请求

AFHTTPSessionManager* manager=[AFHTTPSessionManager manager];
    //    manager.responseSerializer= [AFJSONResponseSerializer serializer];
    NSString* url=[NSString stringWithFormat:@"%@%@",HTTPS_PREFIX,USER_LOGIN];
    NSDictionary* parameters=@{
                               @"account":_accountField.text,
                               @"password":_passwordField.text
                               };
    [manager POST:url parameters:parameters progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
        NSLog(@"%@",responseObject);
        if (![responseObject isKindOfClass:[NSDictionary class]]) return;
        Login* login = [Login mj_objectWithKeyValues:responseObject];
        if (login.meta.status_code==SUCESS) {
            [UserAccountTool saveToken:login.data.token];
            [self dismissViewControllerAnimated:YES completion:nil];
            [self presentViewController:[[MainTabBarController alloc] init] animated:NO completion:nil];
        }else{
            MBProgressHUD* hud = [Tools creatHUD];
            hud.mode = MBProgressHUDModeCustomView;
            hud.label.text = login.meta.message;
            [hud hideAnimated:YES afterDelay:2];
        }
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        MBProgressHUD* hud = [Tools creatHUD];
        hud.mode = MBProgressHUDModeCustomView;
        hud.label.text = NetWork_Err;
        [hud hideAnimated:YES afterDelay:2];
        
    }];

怎么样简单吧，如果有点帮助，帮忙点个赞O(∩_∩)O谢谢！
