AFNetWorking->CYRequestManager->CYBaseRequest
封装了一下网络请求，牵扯到三个类
1. AFNetworking
2. CYRequestManager
3. CYBaseRequest
设计思路
- 先封装一下AFNetworking，即CYRequestManager
- 但是CYRequestManager需要参数、链接，参数和链接还是过于暴露，所以设计CYBaseRequest类
- 使用时继承CYBaseRequest，将类的属性作为参数(模型转JSON)，将属性转化为字典参数，发送请求，即可
- 简单封装，以后逐步完善
用例1
直接使用CYBaseRequest
// 1. 创建请求
CYBaseRequest *request = [CYBaseRequest new];
request.url = @"www.baidu.com";
// 2. 发送请求
[request sendRequestWithCompletionHandle:^(BOOL success, id response, NSString *message) {
}];
}
用例2
创建一个CYUserInfoRequest继承自CYBaseRequest
CYUserInfoRequest.h
@interface CYUserInfoRequest : CYBaseRequest
@property (nonatomic, assign) NSInteger userId;
@end
CYUserInfoRequest.m
@implementation CYUserInfoRequest
- (instancetype)init {
self = [super init];
if (self) {
self.url = @"请求需要的链接";
}
return self;
}
@end
如何使用？
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// 1. 创建请求
CYUserInfoRequest *userInfoR = [CYUserInfoRequest new];
userInfoR.userId = 1;
// 在.m中可以设置
// userInfoR.url = @"www.baidu.com";
// 可选
// userInfoR.extraParams = @{
// @"username" : @"xxx"
// };
// 2. 设置请求方式
userInfoR.methodType = CYRequestMethodTypePOST;
// 3. 发送请求
[userInfoR sendRequestWithCompletionHandle:^(BOOL success, id response, NSString *message) {
}];
}
@end
}
