    })
}

export default http

main.js 添加

import http from './common/http.js'

Vue.prototype.$HTTP = http

调用实例：

this.$HTTP({
  method: 'POST',
  url: '/api/news',
  data: {},
 // baseURL:'http://www.buwang.com'
 // header:'form' 
}).then((res) =>{
  console.log(res)
}
// (err)=>{ console.log(err) }
)
