uniapp package.json和mainfest.json，如何区分环境变量

uniapp在hbuilder中，导航的运行就是development，发行就是production。

• package.json

如果是往服务器上发布版本，则是打包成zip在服务器上解压，但注意打包：是把原有的uniapp项目下的所有文件，放到一个对应vue项目的src下（这个是提前建好的项目），然后打包，打包是根据vue项目中的package.json来打包的。

一般情况下：

往服务器上打包就是yarn run build:h5，但是它对应的 "cross-env NODE_ENV=production UNI_PLATFORM=h5 vue-cli-service uni-build",就是固定的production变量，满足不了测试环境、正式环境获取不同NODE_ENV的需求，所以一般会在vue的这个package.json中新增一份配置，比如   build:dev": "cross-env NODE_ENV=development UNI_PLATFORM=h5 vue-cli-service uni-build",然后测试环境打包就是yarn run  build：dev

• mainfest.json

在jenkins 的shell脚本里面，在

cd ${target_dir}

yarn --registry=https://registry.npm.taobao.org  

之前，加入修改mainfest.json代码的shell命令

sed -i  's!\("base" : "\).*!\1/h5",!g' ${target_dir}/src/manifest.json，意思就是把“base”后面的值改为h5.

sed -i  's!\("base" : "\).*!\1/html/js-h5-test/"!g' ${target_dir}/src/manifest.json  ，意思就是把“base”后面的值改为"base" : "/html/js-h5-test/"
