AFNetworking 网络请求

本文已参与「新人创作礼」活动，一起开启掘金创作之路。

一个简单的笔记，只写了POST请求，GET类似更简单。

#import "AFNetworking.h"
#import "UIImageView+AFNetworking.h"//可以设置图片

NSString *path = @"http://v.juhe.cn/joke/randJoke.php";
    //请求内容
    NSDictionary *params = @{@"key":@"8d0bde7167db666ac160191217840b5b",@"type":@"pic"};
    //创建会话管理器
    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];
    //设置响应序列化
    [manager setResponseSerializer:[AFHTTPResponseSerializer serializer]];
    //发请求
    [manager POST:path parameters:params progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {
//        responseObject 就是服务器返回的data数据
        NSDictionary *dic = [NSJSONSerialization JSONObjectWithData:responseObject options:0 error:nil];
        NSLog(@"%@",dic);
    } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {
        NSLog(@"请求失败:%@",error);
    }];

 UIImageView *iv = [[UIImageView alloc]initWithFrame:[UIScreen mainScreen].bounds];
    [self.view addSubview:iv];
    [iv setImageWithURL:[NSURL URLWithString:@"http://pic2.desk.chinaz.com/file/10.03.10/5/rrgaos36.jpg"] placeholderImage:[UIImage imageNamed:@"2.jpg"]];
