Cross domain problems of Axios

Problem Description:

After using Vue + Axios development for post request, the cross domain problem in the following picture appears

Solution:

Read some relevant information on the Internet, and finally found a solution

module.exports = {
   
   
    dev: {
   
   
        //...
        proxyTable: {
   
   
      '/api': {
   
   
        port: 3000,
        target: 'http://127.0.0.1:8081/',
        chunkOrigins: true,
        pathRewrite: {
   
   
          '^api': ''
        }
      }
    }
}

Modify the proxytable in the index.js file in the config directory

Chunkorigins is whether to turn on cross domain

axios.request({
   
   
          url: '/api/sysUser/selectUserInfo',
          method: 'POST'
        }).then(res => {
   
   
          console.log(res);
        }).catch(res => {
   
   
          console.log('error' + res);
        })

Modifying Axios in Vue component method

Restart the project and send the post request again, and the program is normal
