新建http/http.js文件

//封装get和post请求
function req(method,url, data) {
	var urls = "http://www.dadesc.com";
	uni.showLoading({
		title:'加载中...'
	});
	var datas = "";
	uni.request({
		method: method,
		url: urls+url,
		data: data,
		success(res) {
			datas = res;
			uni.hideLoading()
		},
		fail(err) {
			datas = err;
			uni.showToast({
				title: '请求失败',
				icon: 'none',
				duration: 1500,
			})
			uni.hideLoading()
		}
	})
	return datas;
}
module.exports = {
  req
}

main.js引用

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

Vue.prototype.http = http;

项目直接使用

var data = this.http.req("GET",'/index/login',{});
console.log(data)
