Vue Ajax跨域请求实例详解

一.设置config/index.js || proxyTable添加

proxyTable: {
   '/api': {
      target: 'http://192.168.48.239:8080/ydzl',
      changeOrigin: true,
      pathRewrite: {
        '^/api': ''
      }
   }

二.mian.js 添加vue全局属性

Vue.prototype.HOST = '/api'

三.如果是post的话

1.修改数据格式

transformRequest: [function (data) {
          // Do whatever you want to transform the data
            let ret = ''
            for (let it in data) {
             ret += encodeURIComponent(it) + '=' + encodeURIComponent(data[it]) + '&'
            }
            return ret
           }],

2.修改请求头

headers: {
            'Content-Type': 'application/x-www-form-urlencoded'
          }
