umi 干掉一些乱七八糟的警告和报错

不知道为啥，我自己搭建的umi项目用着用着就多了一些报错和警告

有如下几种:

1. 'react-error-overlay is not meant for use in production. You should ensure it is not included in your build to reduce bundle size.'
2. 'Warning: componentWillReceiveProps has been renamed'
3. 'Warning: componentWillUpdate has been renamed'
4. Warning: Please use \require("history").createHashHistory` instead of `require("history/createHashHistory")`. Support for the latter will be removed in the next major release.`,
5. 'ui socket init',

首先说下第二个和第三个，我用函数式组件写的呀，自己的文件压根就没有componentWillReceiveProps和componentWillUpdate

再说第4个，我搜索了半天，大多数解法竟然是去node_modules改代码...

为什么要干掉呢？ 闹心加影响判断，每天面对着这些无价值的信息，多多少少会浪费一些时间和心情。

就在我不知道该怎么处理好的时候，一篇文章提醒了我，可以用console.warn = ()=>{}来解决

当然，上面的方式过于武断了，于是乎，我在document.ejs中加上如下代码，确保第一个被执行

    <script>
      (() => {
        //过滤掉一些无用的警告、没有价值的报错
        //代理console.warn方法
        const _consoleWarn = console.warn;
        console.warn = (...rest) => {
          if (
            ![
              'react-error-overlay is not meant for use in production. You should ensure it is not included in your build to reduce bundle size.',
              'Warning: componentWillReceiveProps has been renamed',
              'Warning: componentWillUpdate has been renamed',
            ].some((item) => rest[0].indexOf(item) !== -1)
          ) {
            _consoleWarn(...rest);
          }
        };
        //代理console.error
        const _consoleError = console.error;
        console.error = (...rest) => {
          if (
            ![
              `Warning: Please use \`require("history").createHashHistory\` instead of \`require("history/createHashHistory")\`. Support for the latter will be removed in the next major release.`,
              'ui socket init',
            ].includes(rest[0].toString())
          ) {
            _consoleError(...rest);
          }
        };
      })();
    </script>

第一呢，不会影响console.warn和console.error的使用方式
第二呢，确认过不需要处理的报错和警告再进行屏蔽

自己练习的项目不需要考虑部署构建的问题，所以这点代码加在这也没啥影响，但是现在有了一个干干净净的控制台，舒服了!

第五个只要关闭Umi UI就好了。
