背景
项目使用到了一些第三方平台的登录、分享、支付功能,包括了微信、微博、QQ平台登录分享和支付宝、微信平台的支付,使用的是原生的接入配置集成的,功能上基本上对照着SDK的开发文档就能够成功的集成了。但是问题也后面也渐渐的暴露出来了,第三方平台的登录、分享、支付功能不同平台的的SDK实现方式还是有很大的差别的,包括了输入的参数以及回调方式都有差别很大,如果只是简单的按照文档集成,那么一定会遇到代码调用结构很乱,回调杂乱不统一的问题,更为严重的是,后面如果添加删除一个第三发平台,那么修改变得很困难和难以维护,这违反了软件开发中的开闭原则,所以考虑到了把这部分代码做一个重构。
结果
项目实现了添加和删除第三方平台的可扩展,添加或者删除第三发平台只要增加或者移除对应的类和配置即可,不会涉及到已有的代码,客户端的调用也不影响。
项目已经上传了Git->>>我是代码库
先上一个客户端代码调用的代码
[self addActionWithName:@"QQ Login" callback:^{ [[PTThirdPlatformConfigManager sharedInstance] signInWithType:PTThirdPlatformTypeTencentQQ fromViewController:weakSelf callback:^(ThirdPlatformUserInfo *userInfo, NSError *err) { }]; }]; [self addActionWithName:@"Wechat Login" callback:^{ [[PTThirdPlatformConfigManager sharedInstance] signInWithType:PTThirdPlatformTypeWechat fromViewController:weakSelf callback:^(ThirdPlatformUserInfo *userInfo, NSError *err) { }]; }];
问题分析
首先从客户端的角度分析,对于登录、分享、支付功能,基本上我们的输入是固定的:
确定了输入输出关系,接下来的事情就是统一输入输出,这也是这次代码重构的关键。
结构设计
基于以上的分析,对不同平台的SDK的请求和响应设计了对应的接口进行隔离,这部分的设计类似于抽象工厂,不同的第三发平台抽象为了管理工厂,管理工厂实现了一个共同的接口,不同平台的操作(登录、分享、支付的操作可以认为是产品)抽象为了共同的接口调用(这里和抽象工厂不同,没有对这些操作封装为对象然后使用对象再去操作,主要是为了保持代码的简单,防止设计过度)
单个平台(以微信平台为例)的类结构图: 结构图
结构说明:
接口PTAbsThirdPlatformManager抽象了客户端对第三发平台的配置和请求
接口PTAbsThirdPlatformRequestHandler抽象了第三方平台的请求
接口PTAbsThirdPlatformRespManager抽象了第三方平台的响应通过PTAbsThirdPlatformRespManagerDelegate把数据统一回调到PTAbsThirdPlatformManager子类中
类PTWXManager是PTAbsThirdPlatformManager的具体实现,进行微信第三方平台的登录、分享和支付处理
类PTWXRequestHandler是PTAbsThirdPlatformRequestHandler的实现,这里和微信的API打交道
类PTWXRespManager是PTAbsThirdPlatformRespManager的实现,在这里处理微信SDK的回调,并通过PTAbsThirdPlatformRespManagerDelegate把数据回调到PTWXManager
这样添加其他平台,只要对应的添加 【PT平台Manager】、【PT平台RequestHandler】、【PT平台RespManager】这三个类就好了
不同平台的结构好了,接下来需要有一个地方统一管理不同平台,进行统一的配置管理、请求管理:
PTThirdPlatformConfigManager也是PTAbsThirdPlatformManager实现,里面配置了不同的平台对应的管理器,客户端只要传递不同平台的类型以及需要对应的操作,就可以调用对应平台的功能了。现在客户端可以直接和PTThirdPlatformConfigManager打交道了,而不用去和具体的比如PTWXManager、PTWeiboManager等管理器打交道了。
如果客户添加了新的平台,需要再PTThirdPlatformConfigManager进行配置就行了,然后客户端调用的逻辑保持不变。
代码实现
抽象接口部分
客户端第三方平台功能调用的抽象接口,这些接口是第三发平台需要使用到了接口的并集,有的平台需要用到全部,有的只需要部分即可,比如微信到了登录、分享、支付;支付宝用到了只有支付不同的平台根据功能的不同,实现对应的方法即可。

具体的第三发平台调用SDK接口的抽象,因为考虑到考虑到代码的功能清晰性,所以把SDK接口调用的请求和相应部分单独出来,虽然增加了类和代码量,但在代码的职责分离上更清晰。
// // PTAbsThirdPlatformRequestHandler.h // YTThirdPlatformManager // // Created by aron on 2017/10/26. // Copyright © 2017年 aron.

第三发平台响应和回调部分的接口,这部分主要负责把不同SDK的不同回调方式和回调方法统一进行回调,通过PTAbsThirdPlatformRespManagerDelegate定义的方法回调到具体的Manager。

接口实现类部分
首先定义了PTBaseThirdPlatformManager类用于处理不同平台的公共部分,比如说回调block的设置,接收到PTAbsThirdPlatformRespManagerDelegate的回调然后进行客户端的block回调。此外还有分享图片的统一处理,图片统一处理好了之后交给子类进行处理,这里使用到了是模板模式。

具体平台的实现,以微信为例,PTWXManager处理微信平台的SDK初始化配置;设置微信客户端的URL回调的的代理类,即PTWXRespManager的单例对象。然后就是具体的业务功能方法的重写,包含了登录、分享、支付,具体的功能则是交给PTWXRequestHandler类处理,然后设置PTWXRespManager单例对象的delegate为自身,会在父类PTBaseThirdPlatformManager统一的处理回调。

PTWXRequestHandler实现了具体的SDK调用以及其他的一些操作

不同平台的管理类,这部分是用户统一处理客户端的第三发平台功能调用的,因为不同的第三方平台有相同的接口,为了不和具体的第三方平台耦合,使用了类名字符串进行配置不同的平台,客户端只要使用这个类就可以和具体的第三方平台交互了。
