http进行封装

http.js 路径./common/http.js

const baseURL = 'http://localhost:8080';//请求服务器公共地址
const http = (options) => {
	return new Promise((resolve, reject) => {
        uni.showLoading({
            title: '加载中...',
            mask: options.load || false // 默认遮罩出现可继续操作
        });
        try{
            uni.request({
                url: (options.baseURL || baseURL) + options.url,
                method: options.method || 'POST', // 默认为POST请求
                data: options.data, //请求超时在manifest.json配置
				sslVerify:false,
				header: options.method == 'POST' ? {
				 'X-Requested-With': 'XMLHttpRequest',
				 'Content-Type': 'application/json; charset=UTF-8'
				} : {
				 'X-Requested-With': 'XMLHttpRequest',
				 "Accept": "application/json",
				 "Content-Type": "application/json; charset=UTF-8"
				},
                success: res => {
					resolve(res.data);
                },
                fail: (err) => {
                    reject(err);
                    console.log(err);
					
                    uni.showToast({
                        title: '请检查网络连接',
                        icon: 'none'
                    })
                    /*错误码处理
                    let code = err.data.code; 
                    switch (code) {
                        case 500:
                            break;
                        default:
                            break;
                    } */
                },
                complete: () => {
					uni.hideLoading();
                }
            });
        }catch(e){
			uni.hideLoading();
            uni.showToast({
                title: '服务端异常',
                icon: 'none'
            })
        }
        
    })
}

export default http

在main.js中添加

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

Vue.prototype.$HTTP = http

vue页面
调用方法

that.$HTTP({
	method: 'GET',
	url: '/Input/getByNum',//请求具体地址
	data: {
		serialNumber:lineNum
	} 
}).then((res) =>{
	if(res != null){
		//返回数据处理
	}
});
