iOS-HTTP网络请求封装

iOS-HTTP网络请求封装

作者: XTK_iOS | 来源:发表于2021-07-12 11:17 被阅读0次

    一、什么是HTTP

    参考HTTP

    二、根据项目进行封装

    1. 我是基于AFNetWorking 进行封装的
    2. 我这边主要有三个类：NetAPIClient、HttpManager、NSObject+BHRequestSetting，还有一个HttpInfo

    2.1 NetAPIClient

    • 继承AFHTTPSessionManager进行Post 或 get 网络请求、上传图片和上传视频的一个统一处理，暴露接口已供外部类进行统一使用
    #import "AFHTTPSessionManager.h"

@interface NetAPIClient : AFHTTPSessionManager

+ (id)sharedJsonClient;

#pragma mark - 1. Post 或 get 网络请求
/// 1. Post 或 get 网络请求
/// @param aPath 接口名
/// @param params 请求体
/// @param method 请求方式
/// @param block 返回数据
- (void)requestHttpWithPath:(NSString *)aPath withParams:(NSDictionary*)params withMethodType:(NetworkMethod)method andBlock:(void (^)(id data, NSString *msg, NSInteger code))block;


#pragma mark - 2. 外部调用Post 或 get 网络请求
/// 2. Post 或 get 网络请求

/// @param method 请求方式
/// @param block 返回数据
- (void)externalRequestHttpWithPath:(NSString *)aPath withParams:(NSDictionary*)params withMethodType:(NetworkMethod)method andBlock:(void (^)(id data, NSString *msg, NSInteger code))block;


#pragma mark - 3. 上传单张图片
/// 3. 上传图片 和 数据
/// @param aPath 接口名
/// @param name
/// @param image 图片
/// @param params 请求体
/// @param block 返回数据
/// @param progressBlock  
- (void)requestUpFileWithPath:(NSString *)aPath name:(NSString *)name image:(UIImage *)image params:(NSDictionary *)params andBlock:(void (^)(id data, NSString *msg, NSInteger code))block progress:(void (^)(double progress))progressBlock;

#pragma mark - 4. 上传视频
/// 4. 上传视频数据
/// @param aPath 接口名
/// @param videoData 视频
/// @param block 返回数据
/// @param progressBlock  
- (void)requestUpFileWithPath:(NSString *)aPath videoData:(NSData *)videoData andBlock:(void (^)(id data, NSString *msg, NSInteger code))block progress:(void (^)(double progress))progressBlock;
