使用此项目的多页面商城,打包之后出现webpackJsonp的问题!
loveeazy opened this issue · 1 comments
自己的项目,在开发环境中一切都好!但是到了生成环境,会时不时出现,webpackJsonp的问题!
具体情况如下:
1.当出现这个问题时,公共的vendor.js会被加载两次,第一次不是完整的!
2.第二次加载的时完整的,但是页面白屏了!
根据搜索得出的结论,是因为公共的JS文件没有在当前页面逻辑之前载入
但是我查看了html文件的导入顺序如下,并没有错误!
<script type="text/javascript" src="../../static/js/vendor.6ef5a58692797daaf80a.js?6ef5a58692797daaf80a"></script><script type="text/javascript" src="../../static/js/mdx/index/checkIns.6ef5a58692797daaf80a.js?6ef5a58692797daaf80a"></script>
关于webpack.prod.conf.js的配置还是应用当前项目的配置
/*此配置文件主要操作
1 合并基础的webpack配置
2 使用styleLoaders
3 配置webpack的输出
4 配置webpack插件
5 gzip模式下的webpack插件配置
6 webpack-bundle分析
构建的时候用到的webpack配置来自webpack.prod.conf.js,该配置同样是在webpack.base.conf基础上的进一步完善。

但是在浏览器加载的时候并没有办法保证,每次都优先载入公共的js!
请蓝狐赐教,不胜感激!!!!
发现问题了,是由于电信运营商进行了劫持,导致公共JS文件引用出错!现在着手解决,http下,如何不被运营商劫持
