001 - Vue - 跨域

一、cors  全称为 Cross Origin Resource Sharing（跨域资源共享）

二、在 dev 开发模式下可以下使用**webpack 的 proxy

module.exports = {
  dev: {
    // Paths
    assetsSubDirectory: "static",
    assetsPublicPath: "/",
    proxyTable: {
      "/fixed": {
        target: "xxxxxx", // 服务器
        secure: false,
        changeOrigin: true,
        pathRewrite: {
          "^/fixed": ""
        }
      },
      "/area": {
        target: "xxxxxxxx",
        secure: false,
        changeOrigin: true,
        pathRewrite: {
          "^/area": ""
        }
      },
      "/api": {
        target: "xxxxxxxx",
        secure: false,
        changeOrigin: true,
        pathRewrite: {
          "^/api": ""
        }
      }
    },

    // Various Dev Server settings
    //host: 'localhost', // can be overwritten by process.env.HOST
    host: "192.168.10.120",
    port: 8080, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    autoOpenBrowser: false,
    errorOverlay: true,
    notifyOnErrors: true,

    // Run the build command with an extra argument to
