微信小程序实训｜基于云数据库的语文听写工具
本实训项目结合云开发的云数据库和 “微信同声传译”插件，制作一个可真实运营的小学生语文听写工具，页面效果如图1所示。
▍图1 “听写小助手”页面
基于云开发的微信小程序具有众多优势，云开发模式真正解放了开发者，使得开发效率大大提升，其模式下的小程序开发和交付流程也更加便捷；云开发建立了小程序端通向腾讯云和小程序端通向微信的捷径，也为连接其他更多的腾讯云资源提供了捷径，还可以打通云到云、端到端的界限,其计算资源计费更合理，成本也更低。
在小程序互联网飞速发展的时代，教育场景被重塑，教育类小程序迎来猛增。2020年的新冠疫情为在线教育带来了新活力，推动了用户对在线教育的需求。因此，本团队基于在线教育需求研发了“听写好助手”这款小程序。
“听写好助手”是一个以语文为核心，以微信小程序为窗口，以学生及其家长为服务对象的全语音化教学平台。“听写好助手”集语音听写、错题分析、每日十词、复习提醒、个性定制、阶段复习六项功能于一身，采用语音播报模式，减少学生用眼，大大提高了学生的学习效率，同时也减轻了家长在为孩子辅导听写作业上的压力。
本案例以云开发的云数据库为基础，制作一个面向小学语文听写的微信小程序。
01、开发内容
为了实现“听写小助手”的语音播放功能，需要添加插件“微信同声传译”，具体步骤为：登录微信平台，选择“设置”→“第三方设置”→“插件管理”→“搜索插件”并完成添加。添加插件后打开“控制台”→“数据库”，将数据库文件导入数据库，从而完成了小学六年课后的所有单词的储存。最后为了前后端的用户互动需要用云函数来进行操作，为此要完成同步云函数列表以及上传并部署getContent和getUserCollectList云函数操作，重新编译后选择一年级上册的书，即可实现听写功能。同样的导入剩余的数据库集合即可实现所有书册的听写功能。
听写数据单个集合每条记录包含的字段，如图2所示。
▍图2 rn_11集合导入完成
本案例开发主要包括添加插件、数据库页面、云函数上传部署三个步骤。
1、添加插件
听写好助手的代码中使用了微信同声传译的插件，这是由于听写好助手需要将存在数据库中的文字转换成语音，要让代码正常跑起来，需要登录微信公众平台，在“设置”→“第三方设置”→“插件管理”中，添加插件“微信同声传译”，添加插件后，如图3所示。
▍图3添加插件“微信同声传译”
2、页面数据库
添加完插件后再进行重新编译，会发现还有报错，原因是云开发数据库里没有需要的课本对应的数据记录，因此需要进行数据库的导入。数据库文件具体如图四所示。其中，rn_11对应的是一年级上册的听写数据，rn_12对应的是一年级下册的听写数据，以此类推。
▍图4 数据库文件
3、云函数的上传部署
右击cloudfunctions，选择“同步云函数列表”，完成同步云函数列表以及上传并部署getContent和getUserCollectList云函数操作，重新编译后选择一年级上册的书，即可实现听写功能。同样的导入剩余的数据库集合即可实现所有书册的听写功能，如图5所示。
