HarmonyOS 同一份代码，不同的环境（比如测试环境、uat环境、生产环境）有不同的参数、域名、bundleId（包名），需要如何配置打包才能实现？

不同环境的环境变量，可以定义到工程级和模块级的自定义参数中，构建时生成BuildProfile.ets的utl类文件，代码中可直接引用。详见能力说明及实践说明：https://developer.huawei.com/consumer/cn/doc/harmonyos-guides-V5/ide-hvigor-get-build-profile-para-sample-0000001778834309-V5

在工程级下的build-profile.json5中的"signingConfigs"属性下配置这些签名文件路径，可配置多套签名配置，根据"name"属性在"products"中进行绑定。

配置完后单击右上角的product图标，指定需要打包的Product。

包名bundleName需要手动替换。
