IOS 网络请求

前言 ：

各位同学大家好, 有段时间没有给各位更新文章了。具体多久我也不记得了 。今天给大家分享下 ios里面的网络请求 几种方式 。

需要用到的三方库

target 'bosstab' do
    pod 'AFNetworking'
end

• 第一种方式 原生网络请求

// 获取菜单信息
- (void)loadListMenuWithFinishBlock:(GTListLoaderMenuFinishBlock)finishBlock{
    
    NSLog(@"请求数据menu ");
    
    NSString *urlString = @"http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=1";
    NSError * _Nullable error;
   
        NSURL *listURL = [NSURL URLWithString:urlString];
        __weak typeof(self)weakSelf=self;
        NSURLSession * session= [NSURLSession sharedSession];
        NSURLSessionDataTask * dataTask= [session dataTaskWithURL:listURL completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
            __strong typeof(weakSelf)strongSelf=weakSelf;
            NSError  *  jsonError;
            id jsonobject=[NSJSONSerialization JSONObjectWithData:data options:0 error:&jsonError];
          #warning 类型的检查
            NSArray *dataArray =  [jsonobject objectForKey:@"data"];
            NSMutableArray * listItemArray=@[].mutableCopy;
            for (NSDictionary * info in dataArray) {
                Menuitem * listItem= [[Menuitem alloc]init];
                [listItem configWithDictionary:info];
                [listItemArray addObject:listItem];
            }
    
            dispatch_async(dispatch_get_main_queue(), ^{
                if(finishBlock){
                    finishBlock(error==nil,listItemArray.copy);
                }
            });
        }];
        [dataTask resume];
}

• 第二种方式 afnetwork

// 获取菜单信息

- (void)loadListMenuWithAfnetworkFinishBlock:(GTListLoaderMenuFinishBlock)finishBlock{
    NSLog(@"请求数据menu ");
    NSString *urlString = @"http://www.qubaobei.com/ios/cf/dish_list.php?stage_id=1&limit=20&page=1";
    NSError * _Nullable error;
    
    [[AFHTTPSessionManager manager]GET:urlString parameters:nil headers:nil progress:^(NSProgress * _Nonnull downloadProgress) {
              NSLog(@"");
          } success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
              NSLog(@"");
              NSLog(@"请求成功---%@",responseObject);
              NSArray *dataArray =  [responseObject objectForKey:@"data"];
              NSMutableArray * listItemArray=@[].mutableCopy;
              for (NSDictionary * info in dataArray) {
                  Menuitem * listItem= [[Menuitem alloc]init];
                  [listItem configWithDictionary:info];
                  [listItemArray addObject:listItem];
              }

              dispatch_async(dispatch_get_main_queue(), ^{
                  if(finishBlock){
                      finishBlock(error==nil,listItemArray.copy);
                  }
              });
          } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

              NSLog(@"请求失败");

              NSLog(@"");
        
          }];
}

最后总结：

ios 的原生的网络请求,
