具体实施方式
下文中将参考附图并结合实施例来详细说明本申请。需要说明的是,在不冲突的情况下,本申请中的不同实施例及不同实施例中的特征可以相互组合。
在本实施例中提供了一种小程序的编译方法,该编译方法可由至少一个处理器执行。如图1所示,该方法包括步骤101至步骤104。
步骤101,基于源小程序的源代码类型,将所述源小程序的源代码向目标平台的目标代码类型进行转换,得到目标小程序。
本申请实施例用于实现将基于源平台的小程序编译为可以运行在目标平台的小程序,对小程序的编译包括两个部分,其一为执行前编译,其二为执行时编译。获得基于源平台的源小程序后,先针对源小程序进行静态编译。具体地,对小程序的源代码文件进行分析,基于源代码的领域特定语言(DSL,这里用于指代适用于例如支付宝小程序代码编写所使用到的特定编程语言及相关语法规则)类型,如支付宝小程序DSL,从源代码文件中分别读取不同类型的代码文件,并对不同类型的代码文件进行代码转换,以使得转换后得到的目标小程序的代码与目标平台匹配。这里的“匹配”是指代码可被目标平台识别和运行。源平台和目标平台在狭义上可理解为能提供服务的各种小程序,在广义上可理解为能安装或搭载小程序的任何应用、组件、电子设备等等,本申请实施例并不对其具体实现进行限制。
步骤102,在所述目标平台中启动所述目标小程序时,基于所述目标代码类型,配置所述目标小程序的应用程序接口。
在该实施例中,部分类型的代码难以在静态编译时完成代码转换,或者在静态编译阶段可以完成转换,但这种方式带来的性能和代码体积开销较大、或实现编译时转换的成本太高。因此,经过静态编译得到的目标小程序在目标平台中启动后,为保证目标小程序的有效运行,可以进一步对目标小程序进行代码转换。具体可以先基于目标平台对应的目标代码类型,确定目标小程序的应用程序接口API,并对目标小程序的应用程序接口API进行配置,保证小程序调用入参以及结果返回的一致性。
步骤103,依据所述目标小程序的功能构造函数,获取所述功能构造函数对应的替换函数。
步骤104,将所述功能构造函数替换为所述替换函数,并通过调用所述替换函数对所述目标小程序进行功能逻辑转换。
在该实施例中,进行应用程序接口配置后,为保障小程序的各项功能的使用有效性和稳定性,还可以对目标小程序的各功能进行逻辑转换。具体的,可以针对目标小程序的各功能构造函数,确定功能构造函数在目标平台中对应的用于实现逻辑转换的替换函数,利用替换函数对小程序的功能构造函数进行替换,以将替换函数作为小程序功能的入口函数。在相应的功能被调用时,可以调用该功能的功能构造函数对应的替换函数,从而通过调用替换函数对目标小程序的相应功能进行逻辑转换,以使目标小程序与目标平台相匹配,最终使得经过功能逻辑转换后的目标小程序可以稳定、有效的实现相应的功能。
通过应用本实施例的技术方案,对针对源平台开发的源小程序进行代码转换,将源小程序中的源代码转换为与目标平台的目标代码类型匹配的代码,得到目标小程序。接着,在目标平台启动目标小程序后,先对目标小程序的应用程序接口进行配置,以使目标小程序与目标平台的接口适配,保证小程序调用入参以及结果返回的一致性。进一步,利用与目标小程序的各功能构造函数对应的替换函数,对功能构造函数进行替换,通过调用功能构造函数对应的替换函数的方式,来实现对目标小程序的功能逻辑转换。本申请实施例通过对基于源平台的源小程序进行代码转换得到目标小程序,并在目标平台运行目标小程序时,进行应用程序接口配置和功能逻辑转换,保证目标小程序的代码能够有效、稳定的在目标平台运行,减少了针对多个平台进行小程序开发的工作量,提升了小程序开发效率,节约了开发成本。
在本申请实施例中,可选地,所述源代码类型包括多种,所述源小程序包括多种代码类型的代码块。步骤101,具体包括步骤101-1至步骤101-5。
步骤101-1,当所述源小程序包括第一类型代码时,基于所述第一类型代码在目标平 台中对应的第一目标代码类型,对第一类型代码包含的各个代码模块以及各个代码模块之间的引用(reference)(即,导入(import))进行转换,并注入所述目标小程序的新增接口模拟代码,其中,第一类型包括JavaScript(JS)类型。
步骤101-2,当所述源小程序包括第二类型代码时,基于所述第二类型代码在目标平台中对应的第二目标代码类型,对第二类型代码包含的各个代码模块以及各个代码模块之间的引用进行转换,其中,第二类型包括WeiXin Script(WXS)类型和/或Safe/subset javascript(SJS)类型。
步骤101-3,当所述源小程序包括第三类型代码时,基于所述第三类型代码在目标平台中对应的第三目标代码类型,对所述第三类型代码的模板、指令、内置组件以及属性进行转换,其中,第三类型包括WeiXin Markup Language(WXML)类型和/或Android Binary XML(AXML)类型。
步骤101-4,当所述源小程序包括第四类型代码时,基于所述第四类型代码在目标平台中对应的第四目标代码类型,对所述第四类型代码的选择器以及所述第四类型代码之间的引用进行转换,其中,第四类型包括WeiXin Style Sheets(WXSS)类型和/或Alipay Cascading Style Sheets(ACSS)类型。
步骤101-5,当所述源小程序包括第五类型代码时,基于所述第五类型代码在目标平台中对应的第五目标代码类型,对所述第五类型代码的配置项以及所述第五类型代码之间的引用进行转换,其中,第五类型包括JavaScript Object Notation(JSON)类型。
在该实施例中,如图2所示,针对不同类型的代码文件,可以采用不同的代码转换方式进行编译,将其源代码编译为多端产物,即编译为基于一种或多种目标平台的目标小程序。具体的,依据源代码的类型,确定对应的目标代码类型,再依据目标代码类型进行编译。在实际应用场景中,如果源代码文件是JS类型,其对应的目标代码类型为JS类型,那么可以使用Typescript(TypeScript是微软开发的一个开源的编程语言,通过在JavaScript语言的基础上添加静态类型定义构建而成。TypeScript代码通过TypeScript编译器或Babel转译为JavaScript代码,可运行在任何浏览器,任何操作系统)配合转换逻辑,对JS代码的模块和引用进行处理,同时基于小程序目标转换类型(即第一类型代码对应的第一目标代码类型),注入运行时代码转换相关逻辑,并最终生成目标小程序的JS代码。如果文件是WXS或SJS类型,那么可以使用Typescript配合转换逻辑,对WXS或SJS代码的模块和引用进行处理,并最终生成目标小程序的WXS或SJS代码;如果文件是WXML或AXML类型,那么可以使用PostHtml处理器配合转换逻辑,对WXML或AXML代码的模版、指令、内置组件和属性进行处理,并最终 生成目标小程序的WXML或AXML或QML或SWAN或TTML代码;如果文件是WXSS或ACSS类型,那么可以使用PostCSS处理器配合转换逻辑,对WXSS或ACSS代码的选择器和引用进行处理,并最终生成目标小程序的WXSS或ACSS或QSS或CSS或TTSS代码;如果文件是JSON类型,则针对JSON文件所涉及到的小程序配置项和引用进行处理,并最终生成目标小程序的JSON代码。
通过举例来对模块和引用进行处理的作用进行说明。比如对于a.sjs源代码文件引用了b.sjs源代码文件,那么在完成转换之后可以变成a.wxs文件引用了b.wxs文件。这里涉及到的处理分为两部分,第一部分是a.sjs源代码文件和b.sjs源代码文件均被转换成了wxs文件,第二部分是a.sjs文件中对b.sjs文件的引用被替换为了对b.wxs文件的引用。
在本申请实施例中,可选地,步骤101-1中“注入所述目标小程序的新增接口模拟代码”具体包括:基于所述源小程序的源平台以及所述目标平台,识别所述源平台相对于所述目标平台的增加接口,将所述增加接口作为所述目标小程序的新增接口;基于所述目标代码类型,在所述目标小程序中注入所述新增接口模拟代码。
在该实施例中,代码注入主要是针对JS文件,对不同平台小程序框架本身提供的各类接口进行模拟。比如基于平台1的小程序有A接口而基于平台2的小程序没有该接口,那么这时候如果一个平台1小程序需要运行在平台2上,就可以通过运行时代码注入来模拟实现A接口。在这里,比对源平台提供的接口和目标平台提供的接口,获取源平台相对于目标平台多出的接口,即上述的增加接口,将增加接口作为目标小程序的新增接口,从而注入新增接口模拟代码来模拟该接口功能。
在本申请实施例中,可选地,步骤102具体包括:步骤102-1,在所述目标平台中启动所述目标小程序时,基于所述目标代码类型,将所述源小程序对应的源应用程序接口映射为所述目标小程序的目标应用程序接口。
在该实施例中,目标小程序在目标平台启动后,先运行小程序JS API的代码转换逻辑,具体可以将小程序源码DSL在源平台对应的JS API映射为目标小程序在目标平台的JS API,从而保障源代码的API调用入参和结果返回的一致性,保证小程序在目标平台的运行可靠性。
在本申请实施例中,可选地,所述功能构造函数包括注册小程序应用的第一构造函数、注册小程序页面的第二构造函数以及创建小程序自定义组件的第三构造函数;所述替换函数包括用于创建应用的第一替换函数、用于注册页面的第二替换函数以及用于创建组件的第三替换函数。步骤104,具体包括步骤104-1至步骤104-3。
步骤104-1,将所述第一替换函数作为所述目标小程序的应用初始化入口函数,对所述目标小程序的第一构造函数进行替换,并通过调用所述第一替换函数对所述目标小程序的应用注册逻辑进行转换;
步骤104-2,将所述第二替换函数作为所述目标小程序的页面初始化入口函数,对所述目标小程序的第二构造函数进行替换,并通过调用所述第二替换函数,向所述目标小程序注入第一混入对象,以及对所述目标小程序的页面注册逻辑进行转换;
步骤104-3,将所述第三替换函数作为所述目标小程序的自定义组件初始化入口函数,对所述目标小程序的第三构造函数进行替换,并通过调用所述第三替换函数,向所述目标小程序注入第二混入对象,以及对所述目标小程序的自定义组件创建逻辑进行转换。
“混入对象(mixin object)”主要用于组件间或页面间代码共享的特性,可以包含一组属性、数据、生命周期函数和方法。组件或页面引用混入对象时,该混入对象的属性、数据和方法会被合并到组件或页面中,生命周期函数也会在对应时机被调用。在本申请实施例中,通过注入混入对象,可以提供与例如微信小程序Behavior或者支付宝小程序Mixin对等的支持能力,并补足了部分不支持该特性的小程序平台对Mixin的能力支持。
在该实施例中,目标小程序的功能构造函数具体可以包括注册小程序的App构造函数,即第一构造函数App,还可以包括注册小程序页面的构造函数,即第二构造函数Page,还可以包括创建小程序自定义组件的构造函数,即第三构造函数Component。在具体应用场景中,如图3所示,可以将createApp作为第一替换函数,使用createApp替换第一功能构造函数App作为小程序应用初始化的入口函数,在createApp被调用时进行App层面的、向目标平台的结构和逻辑转换,另外在转换完成后执行原App入口函数,即第一功能构造函数,实现相应的小程序应用初始化功能。可以将createPage作为第二替换函数,使用createPage替换第二功能构造函数Page作为小程序页面初始化的入口函数,在createPage被调用时,向目标小程序注入第一混入对象,以注入Mixins支持,并进行页面Page层面的、向目标平台的结构和逻辑转换,并在转换完成后,执行原Page入口函数,即第二功能构造函数,实现相应的小程序页面注册的功能。可以将createComponent作为第三替换函数,使用createComponent替换第三功能构造函数Component作为小程序自定义组件初始化的入口函数,在createComponent被调用时,向目标小程序注入第二混入对象,以注入Mixins的支持,另外对一些类型的平台还可以注入Behavior支持(例如源平台支持Behavior,而目标平台不支持Behavior的情况,需要注入Behavior支持。Behavior是用于组件间代码共享的特性,类似于一些编程语言中的Mixins,每个Behavior可以包含一组属性、数据、生命周期函数和方法,组件引用它时,它的属性、 数据和方法会被合并到组件中,生命周期函数也会在对应时机被调用),以及进行自定义组件Component层面的、向目标平台的结构和逻辑转换,并在转换完成后执行原Component入口函数,即第三功能构造函数。
进一步的,本申请实施例还提供了一种小程序的运行方法,如图4所示,该方法包括步骤401至步骤403。
步骤401,在目标平台中启动目标小程序时,基于所述目标小程序的目标代码类型,配置所述目标小程序的应用程序接口,其中,所述目标小程序通过对源小程序进行代码转换得到。
步骤402,依据所述目标小程序的功能构造函数,获取所述功能构造函数对应的替换函数,并将所述功能构造函数替换为所述替换函数。
步骤403,当所述替换函数被调用时,对所述目标小程序进行功能逻辑转换后,执行所述功能构造函数。
在该实施例中,可以基于源小程序的源代码类型,将所述源小程序的源代码向目标平台的目标代码类型进行转换,得到目标小程序。当需要在目标平台使用该目标小程序时,在目标平台启动目标小程序后,首先对目标小程序在目标平台的应用程序接口进行配置,具体可以基于目标代码类型,将源小程序对应的源应用程序接口映射为目标小程序的目标应用程序接口。接着,基于目标小程序的各功能的功能构造函数,确定功能构造函数对应的替换函数,并将替换函数作为目标小程序相应功能的入口函数,对原来的功能构造函数进行替换。从而通过调用替换函数,对目标小程序进行功能逻辑转换。具体的,可以在小程序的某个功能被调用时,调用该功能的功能构造函数对应的替换函数。通过调用替换函数对小程序进行功能逻辑转换,以使编译和注入的代码能够在目标平台运行时生效。功能逻辑转换结束后执行原来的功能构造函数,实现小程序的功能。换句话说,在目标小程序运行时,通过将代码逻辑动态添加到正确的内存对象上,以保证目标小程序能被正确的调用。即,通过调用替换函数保证目标小程序被编译和注入的代码生效,使目标小程序能够稳定、有效的在目标平台运行,而后使用小程序功能时,执行对应的功能构造函数即可。
在本申请实施例中,可选地,步骤403具体包括步骤403-1至步骤403-2。
步骤403-1,在对所述目标小程序进行首次功能调用时,执行所述替换函数以对所述目标小程序进行功能逻辑转换,存储逻辑转换结果,并基于所述逻辑转换结果执行所述功能构造函数。
步骤403-2,在对所述目标小程序进行非首次功能调用时,基于所述逻辑转换结果 执行所述功能构造函数。
在该实施例中,对于目标小程序包含的各功能,只需要在功能被首次调用时,运行一次该功能对应的替换函数,通过替换函数对该功能进行逻辑转换,并将逻辑转换结果存储在本地内存中,进而在该功能下一次被调用时,由于之前已经进行过逻辑转换,且存储了逻辑转换结果,可以直接在内存中调用逻辑转换结果,并基于逻辑转换结果直接执行对应的功能构造函数即可。另外,小程序页面关闭时,销毁逻辑转换结果,清除内存,避免造成内存占用,影响设备运行效率。
需要说明的是,如图4所示的实施例中,目标小程序可以通过步骤101-1至步骤101-5的方式实现,步骤401可以通过步骤102-1的方式实现,步骤402至步骤403可以参考步骤104-1至步骤104-3的方式来实现功能逻辑转换,在此不再赘述。
进一步的,作为图1方法的具体实现,本申请实施例提供了一种小程序的编译装置500,如图5所示,该装置包括以下模块。
代码转换模块501,用于基于源小程序的源代码类型,将所述源小程序的源代码向目标平台的目标代码类型进行转换,得到目标小程序。
接口配置模块502,用于在所述目标平台中启动所述目标小程序时,基于所述目标代码类型,配置所述目标小程序的应用程序接口。
