axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded';

proxyTable: {

  '/apis': {
    target: 'http://192.168.1.109/xxx/aa', 
    changeOrigin: true,
    pathRewrite: {
      '^/apis': '' 
      }
  }
}

this.$http.post('/apis/bbb/cccc', {

  json:JSON.stringify({})
})
