基于AFNetworking封装的HttpsRequest类

首先说明下为什么要自己封装一层这个类，因为项目需要，不同的接口实现不同的通信协议，所以自己封装了一层来控制相关的类来处理一些操作！比如Get、Post、Put、Delete...
这个类也是主要封装了以上几个方法！

—————————————————————————————————————————————————————————————
我用了cocoaPods来管理AFNetworking。这个应该不用再说明怎么导入使用这个类库了吧！
这里面还用到了UICKeyChainStore这个存储信息的第三方类
PDToast 还用了我自己写的的一个动态库PDFramework里面的一个功能

下面来说重点：

HttpsRequest.h

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface HttpsRequest : NSObject

+(HttpsRequest *)getInstance;

- (void)GetData:(NSMutableDictionary *)params :(NSString *)url andBlock:(void(^)(id requsetStr))block;

- (void)PostData:(NSMutableDictionary *)params :(NSString *)url andBlock:(void(^)(id requsetStr))block;

- (void)PUTData:(NSMutableDictionary *)params :(NSString *)url andBlock:(void(^)(id requsetStr))block;

- (void)DeleteData:(NSMutableDictionary *)params :(NSString *)url andBlock:(void(^)(id requsetStr))block;

@property (nonatomic, retain) UIView *selfView;

@end

HttpsRequest.m

#import "HttpsRequest.h"
#import <AFNetworking.h>
#import <CommonCrypto/CommonDigest.h>
#import "General.h"//这个是写配置的文件（这个文件里面写了一些宏定义，如果你需要直接使用这两个类的话，拷贝代码报警告或者错误的话，自行修改错误的地方吧！）

}

下面是具体的使用方法
Viewcontroller.m里面具体使用

#import "Server0.h"

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor whiteColor];
    
    //登录
    NSMutableDictionary *dic = [[NSMutableDictionary alloc]init];
    [dic setObject:@"123456789" forKey:@"mobile"];
    [dic setObject:@"123456" forKey:@"captcha"];
    [self getLogin:dic];
    
    //注册
    NSMutableDictionary *dic = [[NSMutableDictionary alloc]init];
    [dic setObject:@"123456" forKey:@"mobile"];
    [dic setObject:@"123" forKey:@"captcha"];
    [dic setObject:@"123455"forKey:@"referrerMobile"];
    [self getRegister:dic];
    NSLog(@"%@ %@",phone,verCode);
    
  
}


- (void)getLogin:(NSMutableDictionary *)dic{
    
    [[Server0 getInstance] Login:self.view :dic :^(id requsetStr) {
        if (requsetStr == 0)
        {
            
        }
        else
        {
            
            NSLog(@"%@",requsetStr);

            [UICKeyChainStore setString:[NSString stringWithFormat:@"%@",requsetStr[@"flag"]] forKey:@"flag" service:keychainValue];
            [UICKeyChainStore setData:requsetStr[@"pages"] forKey:@"pages" service:keychainValue];
            [UICKeyChainStore setString:[NSString stringWithFormat:@"%@",requsetStr[@"sessionID"]] forKey:@"sessionID" service:keychainValue];
            [UICKeyChainStore setString:@"LoginSucceed" forKey:@"Login" service:keychainValue];

        }
    }];
}

- (void)getRegister:(NSMutableDictionary *)dic{
        //dic为入参的参数结构体
        
        [[Server0 getInstance] Register:self.view :dic :^(id requsetStr) {
            if (requsetStr == 0)
            {
                
            }
            else
            {
                
                NSLog(@"%@",requsetStr);
                [UICKeyChainStore setString:[NSString stringWithFormat:@"%@",requsetStr[@"flag"]] forKey:@"flag" service:keychainValue];
                [UICKeyChainStore setData:requsetStr[@"pages"] forKey:@"pages" service:keychainValue];
                [UICKeyChainStore setString:[NSString stringWithFormat:@"%@",requsetStr[@"sessionID"]] forKey:@"sessionID" service:keychainValue];
                [UICKeyChainStore setString:@"LoginSucceed" forKey:@"Login" service:keychainValue];

            }
        }];
}

这里我只列出了几个常用的方法，具体数据处理还要看自己对应的需求
requsetStr我自己做了一点处理 请求数据返回的数据里面如果有data为key的数据，会自动解析返回data对应的value值，所以requsetStr不同的接口返回的可能是字典也可能是数组！
如果大家有什么看不明白的地方可以留言给我！空一点我会写一个demo放到我的github上去！可能会更详细！

感谢大家的支持，我会继续努力为大家带来更多更好的开发上面的分享！
