我用一个单例类将一些常用的网络请求进行了二次封装，主要包括post请求 get请求 图片文件上传下载 视频的断点续传等功能。
首先大家先去github上下载AFN，将文件夹内的AFNetworking文件夹拖入工程中，然后创建一个图片文件参数类代码如下：
#import <Foundation/Foundation.h>@interface UploadParam : NSObject /*** 上传文件的二进制数据*/ @property (nonatomic, strong) NSData *data; /*** 上传的参数名称*/ @property (nonatomic, copy) NSString *name; /*** 上传到服务器的文件名称*/ @property (nonatomic, copy) NSString *fileName;/*** 上传文件的类型*/ @property (nonatomic, copy) NSString *mimeType;@end
#import "UploadParam.h"@implementation UploadParam@end
然后创建网络工具AFNManager具体代码如下(此处我提供了代理和block两种方式进行传值供大家选择)：
#import <Foundation/Foundation.h> #import "AFNManagerDelegate.h" #import "UploadParam.h" @interface AFNManager : NSObject@property (nonatomic, weak) id<AFNManagerDelegate> delegate;/*** AFNManager单利*/ +(AFNManager *)sharedManager; #pragma mark --代理的方式传值 /*** get*/ - (void)GET:(NSString *)URLString parameters:(id)parameters;/*** post*/ - (void)Post:(NSString *)URLString parameters:(id)parameters;/*** upload*/ - (void)Upload:(NSString *)URLString parameters:(id)parameters uploadParam:(UploadParam *)uploadParam;#pragma mark --block的形式传值 /*** get请求*/ - (void)GET:(NSString *)URLString parameters:(id)parameters succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure; /*** post请求*/ - (void)Post:(NSString *)URLString parameters:(id)parameters succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure; /*** upload*/ - (void)Upload:(NSString *)URLString parameters:(id)parameters uploadParam:(UploadParam *)uploadParam succeed:(void (^)(id data))succeed failure:(void (^)(NSError *error))failure;#pragma mark --断点续传 /*** 开始下载 断点续传** @param URLString 请求接口*/ - (void)downloadStartWithUrl:(NSString *)URLString fileName:(NSString *)fileName; /*** 开始上传 断点续传** @param URLString 请求接口*/ - (void)uploadStartWithUrl:(NSString *)URLString fileData:(NSData *)fileData; /*** 暂停操作 断点续传*/ - (void)operationPause; /*** 继续操作 断点续传*/ - (void)operationResume; /*** 取消操作*/ - (void)operationCancel; @end
#import "AFNManager.h" #import "AFNetworking.h" @interface AFNManager() {AFHTTPRequestOperation *operation; //创建请求管理（用于上传和下载） } @end static AFNManager *manager = nil; @implementation AFNManager +(AFNManager *)sharedManager {static dispatch_once_t onceToken;dispatch_once(&onceToken, ^{if (manager == nil) {manager = [[self alloc] init];}});return manager;

网络工具代理协议代码如下：
#import <Foundation/Foundation.h> @class AFNManager;@protocol AFNManagerDelegate <NSObject>@optional /*** 发送请求成功** @param manager AFNManager*/ -(void)AFNManagerDidSuccess:(id)data; /*** 发送请求失败** @param manager AFNManager*/ -(void)AFNManagerDidFaild:(NSError *)error; @end
菜鸟二次投诉是怎么投诉，有很多不足之处请大家多多指正，可以评论或点关注进行技术交流。后续也会写一些自己平时学习的点点滴滴。
