iOS第三方平臺集成組件化

背景

項目使用到了一些第三方平臺的登錄、分享、支付功能，包括了微信、微博、QQ平臺登錄分享和支付寶、微信平臺的支付，使用的是原生的接入配置集成的，功能上基本上對照著SDK的開發(fā)文檔就能夠成功的集成了。但是問題也后面也漸漸的暴露出來了，第三方平臺的登錄、分享、支付功能不同平臺的的SDK實現(xiàn)方式還是有很大的差別的，包括了輸入的參數(shù)以及回調(diào)方式都有差別很大，如果只是簡單的按照文檔集成，那么一定會遇到代碼調(diào)用結(jié)構(gòu)很亂，回調(diào)雜亂不統(tǒng)一的問題，更為嚴(yán)重的是，后面如果添加刪除一個第三發(fā)平臺，那么修改變得很困難和難以維護(hù)，這違反了軟件開發(fā)中的開閉原則，所以考慮到了把這部分代碼做一個重構(gòu)。

結(jié)果

項目實現(xiàn)了添加和刪除第三方平臺的可擴(kuò)展，添加或者刪除第三發(fā)平臺只要增加或者移除對應(yīng)的類和配置即可，不會涉及到已有的代碼，客戶端的調(diào)用也不影響。

先上一個客戶端代碼調(diào)用的代碼

[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) {

}];

}];

問題分析

首先從客戶端的角度分析，對于登錄、分享、支付功能，基本上我們的輸入是固定的：

確定了輸入輸出關(guān)系，接下來的事情就是統(tǒng)一輸入輸出，這也是這次代碼重構(gòu)的關(guān)鍵。

結(jié)構(gòu)設(shè)計

基于以上的分析，對不同平臺的SDK的請求和響應(yīng)設(shè)計了對應(yīng)的接口進(jìn)行隔離，這部分的設(shè)計類似于抽象工廠，不同的第三發(fā)平臺抽象為了管理工廠，管理工廠實現(xiàn)了一個共同的接口，不同平臺的操作（登錄、分享、支付的操作可以認(rèn)為是產(chǎn)品）抽象為了共同的接口調(diào)用（這里和抽象工廠不同，沒有對這些操作封裝為對象然后使用對象再去操作，主要是為了保持代碼的簡單，防止設(shè)計過度）

單個平臺（以微信平臺為例）的類結(jié)構(gòu)圖： 結(jié)構(gòu)圖

結(jié)構(gòu)說明：

接口PTAbsThirdPlatformManager抽象了客戶端對第三發(fā)平臺的配置和請求

接口PTAbsThirdPlatformRequestHandler抽象了第三方平臺的請求

接口PTAbsThirdPlatformRespManager抽象了第三方平臺的響應(yīng)通過PTAbsThirdPlatformRespManagerDelegate把數(shù)據(jù)統(tǒng)一回調(diào)到PTAbsThirdPlatformManager子類中

類PTWXManager是PTAbsThirdPlatformManager的具體實現(xiàn)，進(jìn)行微信第三方平臺的登錄、分享和支付處理

類PTWXRequestHandler是PTAbsThirdPlatformRequestHandler的實現(xiàn)，這里和微信的API打交道

類PTWXRespManager是PTAbsThirdPlatformRespManager的實現(xiàn)，在這里處理微信SDK的回調(diào)，并通過PTAbsThirdPlatformRespManagerDelegate把數(shù)據(jù)回調(diào)到PTWXManager

這樣添加其他平臺，只要對應(yīng)的添加 【PT平臺Manager】、【PT平臺RequestHandler】、【PT平臺RespManager】這三個類就好了

不同平臺的結(jié)構(gòu)好了，接下來需要有一個地方統(tǒng)一管理不同平臺，進(jìn)行統(tǒng)一的配置管理、請求管理：

PTThirdPlatformConfigManager也是PTAbsThirdPlatformManager實現(xiàn)，里面配置了不同的平臺對應(yīng)的管理器，客戶端只要傳遞不同平臺的類型以及需要對應(yīng)的操作，就可以調(diào)用對應(yīng)平臺的功能了。現(xiàn)在客戶端可以直接和PTThirdPlatformConfigManager打交道了，而不用去和具體的比如PTWXManager、PTWeiboManager等管理器打交道了。

如果客戶添加了新的平臺，需要再PTThirdPlatformConfigManager進(jìn)行配置就行了，然后客戶端調(diào)用的邏輯保持不變。

代碼實現(xiàn)

抽象接口部分

客戶端第三方平臺功能調(diào)用的抽象接口，這些接口是第三發(fā)平臺需要使用到了接口的并集，有的平臺需要用到全部，有的只需要部分即可，比如微信到了登錄、分享、支付；支付寶用到了只有支付不同的平臺根據(jù)功能的不同，實現(xiàn)對應(yīng)的方法即可。

具體的第三發(fā)平臺調(diào)用SDK接口的抽象，因為考慮到考慮到代碼的功能清晰性，所以把SDK接口調(diào)用的請求和相應(yīng)部分單獨出來，雖然增加了類和代碼量，但在代碼的職責(zé)分離上更清晰。

具體平臺的實現(xiàn)，以微信為例，PTWXManager處理微信平臺的SDK初始化配置；設(shè)置微信客戶端的URL回調(diào)的的代理類，即PTWXRespManager的單例對象。然后就是具體的業(yè)務(wù)功能方法的重寫，包含了登錄、分享、支付，具體的功能則是交給PTWXRequestHandler類處理，然后設(shè)置PTWXRespManager單例對象的delegate為自身，會在父類PTBaseThirdPlatformManager統(tǒng)一的處理回調(diào)。

不同平臺的管理類，這部分是用戶統(tǒng)一處理客戶端的第三發(fā)平臺功能調(diào)用的，因為不同的第三方平臺有相同的接口，為了不和具體的第三方平臺耦合，使用了類名字符串進(jìn)行配置不同的平臺，客戶端只要使用這個類就可以和具體的第三方平臺交互了。
