vue 跨域请求数据，点击列表转详情页

以腾讯校招公告接口为例：https://join.qq.com/api/v1/noticeDynamic/getNoticeDynamicList 

在view文件夹里分别创建 列表页Lb.vue和内容页Nr.vue,并在router路由文件index.js里引入

没设置跨域之前访问不到数据，控制台以Access to XMLHttpRequest开头的报错，这就是跨域.

解决：src文件夹同级目录创建vue.config.js

vue.config.js内容：

module.exports = {
  devServer: {
    proxy: {
      // 配置跨域，请求后端接口
      "/tx": {
        target: "https://join.qq.com/",
        changeOrigin: true,
        pathRewrite: {
          '^/tx': ''
        },
      },
    },
  },
};
