1.创建名为HTTPMethod(自己随便起名字)的头文件

2.导入AFNetworking头文件(在github上下载最新版):

#import "AFNetworking.h"

3.在.h文件里声明类方法:

　　　　//参数解释:(1)urlString是你想请求的网址 (2)bodyDic是POST请求时的参数 (3)dataBlock是数据请求成功后用来回调数据的block

+ (void)getDataByString:(NSString *)urlString BodyDic:(NSDictionary *)bodyDic WithDataBlock:(void(^)(id data))dataBlock;

4.方法的实现:

+(void)getDataByString:(NSString *)urlString BodyDic:(NSDictionary *)bodyDic WithDataBlock:(void (^)(id))dataBlock{    //(1).字符串的转码    urlString = [urlString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet characterSetWithCharactersInString:urlString]];    //(2).创建管理者对象(session)    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];    //(3).设置允许请求的类别    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain",@"text/json",@"application/json",@"text/javascript",@"text/html", @"application/javascript", @"text/js", nil];    //(4).开始请求    if (!bodyDic) {        //如果bodyDic为空就执行get请求        [manager GET:urlString parameters:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {            dataBlock(responseObject);        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {            NSLog(@"请求失败");        }];    }    else    {        [manager POST:urlString parameters:bodyDic success:^(NSURLSessionDataTask * _Nonnull task, id  _Nonnull responseObject) {            dataBlock(responseObject);        } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {            NSLog(@"请求失败");        }];    }}
