需求：是动态切换主题色；
思路一：配置不同的less文件，然后逻辑判断进行引用文件；
思路二：参考Aant Pro项目引用webpack-theme-color-replacer插件来实现；
思路三：window.less.modifyVars和antd-theme-generator来动态更新主题色；

查了很多资料，一一实现了之后，最后用了思路三实现了。

1.相关插件版本

    "ant-design-vue": "^1.7.4",
    "antd-theme-generator": "^1.2.8",
    "vue": "^2.6.11",

2.在package.json执行changeTheme.js文件
package配置如下

 "serve": "node changeTheme && vue-cli-service serve",
 "build": "node changeTheme && vue-cli-service build",

changeTheme.js在根目录下，文件内容如下：

注意：

1. 你想要更改的ant组件可以在themeVariables下进行配置，如下是我自己的配置，可根据自己的项目进行修改
2. antTheme.less文件要包含你想要更改的ant组件样式名称，最好和themeVariables里面的一一对应；
3. var.less文件设置可以为空，主要是有对应到mainLessFile的；

const path = require('path')
const { generateTheme } = require('antd-theme-generator')
const options = {
  antDir: path.join(__dirname, './node_modules/ant-design-vue'), //对应具体位置
  stylesDir: path.join(__dirname, './src/assets/css'), //对应具体位置
  varFile: path.join(__dirname, './src/assets/css/antTheme.less'), //对应具体位置
  mainLessFile: path.join(__dirname, './src/assets/css/var.less'), //对应具体位置
  themeVariables: [
    '@primary-color',
    '@info-color',
    '@link-color',
    '@text-color',
    '@btn-primary-bg',
  ],
  indexFileName: 'index.html',
  outputFilePath: path.join(__dirname, './public/color.less')
}
generateTheme(options)
  .then(less => {
    console.log('Theme generated successfully')
  })
  .catch(error => {
    console.log('Error', error)
  })

3.antTheme.less 文件内容如下：

@primary-color: #1890ff; // 全局主色
@btn-primary-bg: #1890ff;
@link-color: #1890ff; // 链接色
@info-color: #1890ff;

4.public目录下index.html文件在body标签里面新增，内容如下：

 <link rel="stylesheet/less" type="text/css" href="/color.less" />
    <script>
      window.less = {
        async: false,
        env: 'production'
      }
    </script>
    <script
      type="text/javascript"
      src="/less.min.js"
    ></script>

注意：

1. 需要新建个color.less的空文件，在运行npm run serve 命令时，同时执行changeTheme文件，color.less文件里面会被编译，内容会有antTheme.less+ant-design-vue/dist/antd.less
2. /less.min.js ,可以引用网络地址，这里我把依赖下载下来了，这样出现问题也可控；
