最近这几个月都在完成一个项目，项目里面用到了太多的数据请求，一开始还是在用以前的那种传统的请求方式，这样下来代码量就显得太多了，于是就产生了对数据请求进行一个工具类的封装，这样省事。经过这几个月的不断试验修改，现在这个工具类已经很成熟了，非常稳定了，今天给大家分享一下，废话少说了，直接上代码！
注意：这篇文章有点长，看起来有点复杂，如果您没有做好看完这篇文章的准备，我建议您还是别再往下看了，以免影响您的心情，不过您要是坚持看到最后，肯定与惊喜！
首先建立一个继承与NSObject的类命名为：LBRequest

创建FRBaseHttpManage继承与NSObject
FRBaseHttpManage.h文件
#import<Foundation/Foundation.h>
#import#import "LBService.h"
@interface FRBaseHttpManage : NSObject
@property(nonatomic,strong)NSMutableDictionary *parameters;
@property(nonatomic,copy)NSString *requestUrl;
@end
FRBaseHttpManage.m文件
#import "FRBaseHttpManage.h"
@implementation FRBaseHttpManage
- (instancetype)init
{
self = [super init];
if (self) {
_requestUrl=@"";
_parameters=[NSMutableDictionary dictionary];
}
return self;
}
@end
到这里为止，工具类基本上建好了，下面就是如何使用了
建立FRHomeManage继承FRBaseHttpManage
FRBaseHttpManage.h文件
#import "FRBaseHttpManage.h"
typedef enum : NSUInteger{
ISHomeTypeFocusBrand,
} ISSettingType;
@interface FRHomeManage : FRBaseHttpManage
//定义一个对外的方法
//把要传的参数写在方法里面
-(void)home:(ISSettingType)type PageNumber:(int)pageNumber PageSize:(int)pageSize completion:(void (^)(NSDictionary *,LBResponse *))completion;
@end
FRBaseHttpManage.m文件
#import "FRHomeManage.h"
@implementation FRHomeManage
//实现这个方法
-(void)home:(ISSettingType)type PageNumber:(int)pageNumber PageSize:(int)pageSize completion:(void (^)(NSDictionary *, LBResponse *))completion{
self.parameters=[NSMutableDictionary dictionary];
switch (type) {//判断类型
case ISHomeTypeFocusBrand:
{//以下为要传的参数，根据各自的需求传参
self.requestUrl=FRURL_String(FocusBrandURL);//请求的url
if (app.user.Id) self.parameters[@"memberId"]=app.user.Id;
self.parameters[@"pageNumber"]=@(pageNumber);
self.parameters[@"pageSize"]=@(pageSize);
}
break;
default:
break;
}
//这里分了为get和post请求
[LBService get:self.requestUrl params:self.parameters completion:^(LBResponse *response){
if (response.succeed) {
switch (type) {
case ISHomeTypeFocusBrand:
{
NSLog(@"关注品牌:%@",response.result);//请求成功了打印数据
completion(response.result,response);
}
break;
default:
break;
}
}else completion(nil,response);
}];
}
在控制器里实现这个方法
-(void)requestFocusData{
WEAKSELF;
[weakSelf addHUD:@"正在加载数据..."];
FRHomeManage *manage=[[FRHomeManage alloc]init];
[manage home:ISHomeTypeFocusBrand PageNumber:1 PageSize:100 completion:^(NSDictionary *array, LBResponse *response){
[weakSelf.HUD hide:YES];
if (response.succeed) {//判断是否请求成功，返回的是json类型
_focusArray=[array objectForKey:@"data"];
[_collectionView reloadData];
[weakSelf addHUD:[array objectForKey:@"message"]];
}else{
[weakSelf addHUD:[array objectForKey:@"message"]];
}
}];
}
到这里，基本上就把请求工具类的封装使用介绍完毕了，如果看不懂，可以联系我要源码！
