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
