关于请求工具类的封装---FRBaseHttpManage

        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！
