    AFNetworking网络请求库

    导入AFNetworking.h头文件

    //ASIHttpRequest,有三年多没更新,而且还是MRC,跟不上技术的发展了

    //在ARC基本上全部都是使用AFNetworking:ARC下的一个网络请求库,还在不断的更新,使用简单方便

    //发请求:全部都是异步请求,没有同步请求的方法

    //使用manager可以发起GET/PUT/POST/PATCH...请求

    //AFHTTPRequestOperationManager  -----> 2.0 NSURLConnection

    //AFHTTPSessionManager      --------> 3.0 NSURLSession

    //创建网络请求管理类

    AFHTTPSessionManager *manager = [AFHTTPSessionManager manager];

    //AFNetworking:默认只支持三种响应头:application/json   text/json  text/JavaScript

    //我们常用的还有一种:text/html,如果服务器需要该类型,则设置下面的参数

    //(请求失败:在error中出现类似text/html这种类型的参数是再设置)

    /*解析数据json

    //响应头

    manager.responseSerializer.acceptableContentTypes = [NSSet setWithObject:@"text/html"];

    [manager GET:@"http://localhost:8080/Login1/NewServlet?command=5" parameters:nil progress:nil success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

    //处理请求成功的事件

    //AFNetworking:返回的参数是json,AFNetworking会自动返回解析后的数据(NSArray,NSDictionary)

    //不需要使用NSJSONSerialization解析json

    if ([responseObject isKindOfClass:[NSData class]]) {

    NSLog(@"data ----> %@",[[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]);

    }else if ([responseObject isKindOfClass:[NSDictionary class]]){

    NSLog(@"Dic -----> %@",responseObject);

    }

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

    //处理请求失败的事件

    NSLog(@"----->%@",error);

    }];

    */

    /*

    请求数据格式

    AFHTTPRequestSerializer二进制格式

    AFJSONRequestSerializer     JSON

    AFPropertyListRequestSerializer    PList(是一种特殊的XML,解析起来相对容易)

    响应数据格式

    AFHTTPResponseSerializer 二进制格式

    AFJSONResponseSerializer   JSON

    AFXMLParserResponseSerializer     XML,只能返回XMLParser,还需要自己通过代理方法解析

    AFXMLDocumentResponseSerializer (Mac OS X)

    AFPropertyListResponseSerializer   PList

    AFImageResponseSerializer          Image

    AFCompoundResponseSerializer组合
