node简单服务器api

cors包

设置请求头方法

header("Access-Control-Allow-Origin: *"); // 允许任意域名发起的跨域请求
header('Access-Control-Allow-Headers: X-Requested-With,X_Requested_With');

Vue中psot请求后台node接收不到参数

      let pars = new URLSearchParams();
      pars.append("user","yhm");
      this.$axios.post("/s",pars).then((res)=>{
        console.log(res);
      })    

      或者

      import qs from 'qs';
      Vue.prototype.$qs = qs;
      this.$axios.post("/s", this.$qs.stringify({"user":"1213"})).then(res => {
        console.log(res);
      });
