? ? ? ? 最近這幾個月都在完成一個項目，項目里面用到了太多的數據請求，一開始還是在用以前的那種傳統的請求方式，這樣下來代碼量就顯得太多了，于是就產生了對數據請求進行一個工具類的封裝，這樣省事。經過這幾個月的不斷試驗修改，現在這個工具類已經很成熟了，非常穩定了，今天給大家分享一下，廢話少說了，直接上代碼！
注意：這篇文章有點長，看起來有點復雜，如果您沒有做好看完這篇文章的準備，我建議您還是別再往下看了，以免影響您的心情，不過您要是堅持看到最后，肯定與驚喜！
首先建立一個繼承與NSObject的類命名為：LBRequest

創建FRBaseHttpManage繼承與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
到這里為止，工具類基本上建好了，下面就是如何使用了
建立FRHomeManage繼承FRBaseHttpManage
FRBaseHttpManage.h文件
#import "FRBaseHttpManage.h"
typedef enum : NSUInteger{
ISHomeTypeFocusBrand,
} ISSettingType;
@interface FRHomeManage : FRBaseHttpManage
//定義一個對外的方法
//把要傳的參數寫在方法里面
-(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
//實現這個方法
-(void)home:(ISSettingType)type PageNumber:(int)pageNumber PageSize:(int)pageSize completion:(void (^)(NSDictionary *, LBResponse *))completion{
self.parameters=[NSMutableDictionary dictionary];
switch (type) {//判斷類型
case ISHomeTypeFocusBrand:
{//以下為要傳的參數，根據各自的需求傳參
self.requestUrl=FRURL_String(FocusBrandURL);//請求的url
if (app.user.Id) self.parameters[@"memberId"]=app.user.Id;
self.parameters[@"pageNumber"]=@(pageNumber);
self.parameters[@"pageSize"]=@(pageSize);
}
break;
default:
break;
}
//這里分了為get和post請求
[LBService get:self.requestUrl params:self.parameters completion:^(LBResponse *response){
if (response.succeed) {
switch (type) {
case ISHomeTypeFocusBrand:
{
NSLog(@"關注品牌:%@",response.result);//請求成功了打印數據
completion(response.result,response);
}
break;
default:
break;
}
}else completion(nil,response);
}];
}
在控制器里實現這個方法
-(void)requestFocusData{
WEAKSELF;
[weakSelf addHUD:@"正在加載數據..."];
FRHomeManage *manage=[[FRHomeManage alloc]init];
[manage home:ISHomeTypeFocusBrand PageNumber:1 PageSize:100 completion:^(NSDictionary *array, LBResponse *response){
[weakSelf.HUD hide:YES];
if (response.succeed) {//判斷是否請求成功，返回的是json類型
_focusArray=[array objectForKey:@"data"];
[_collectionView reloadData];
[weakSelf addHUD:[array objectForKey:@"message"]];
}else{
[weakSelf addHUD:[array objectForKey:@"message"]];
}
}];
}
到這里，基本上就把請求工具類的封裝使用介紹完畢了，如果看不懂，可以聯系我要源碼！
