AFNETWorking三方封装

1.先下载AFNETWorking三方

2.导入到自己的程序中

3.在程序中新建文件AFNModel

在AFNModel.h 中

//定义block

typedef void(^NETBLOCK) (id result);

@interface AFNModel : BaseModel

//GET

+ (void)GETWithURL:(NSString *)str completion:(NETBLOCK)netblock;

@end

在AFNModel.m中

先导入AFNETWorking

+ (void)GETWithURL:(NSString *)str completion:(NETBLOCK)netblock

{

    //中文转码

    NSString *newStr = [strstringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSetcharacterSetWithCharactersInString:str]];

    //创建AFN管理

    AFHTTPSessionManager *seccionManager = [AFHTTPSessionManagermanager];

    seccionManager.responseSerializer = [AFHTTPResponseSerializerserializer];

    

    //进行get请求

    [seccionManager GET:newStr parameters:nil progress:^(NSProgress * _Nonnull downloadProgress) {

        NSLog(@"%lld", downloadProgress.totalUnitCount);

        

    } success:^(NSURLSessionDataTask *_Nonnull task,id _Nullable responseObject) {

        //JSON解析

        id result = [NSJSONSerializationJSONObjectWithData:responseObjectoptions:NSJSONReadingMutableContainerserror:nil];

        netblock(result);

        

    } failure:^(NSURLSessionDataTask *_Nullable task,NSError *_Nonnull error) {

        NSLog(@"%@", error);

        

    }];

}

数据解析

导入AFNModel.h

    [AFNModel GETWithURL:@"网址" completion:^(id result) {

    

}];
