1. 新建request.js文件，用來配置請求和響應

export default {
    config: {
        baseURL: 'https://www.holardata.com/ergj',
        getToken() {
            let token = uni.getStorageSync('userToken');
            if (!token) {
                return uni.switchTab({
                    url: '/pages/login/login'
                })
            }
            return token
        },
        // 請求攔截器
        beforeRequest(options = {}) {
            return new Promise((resolve, reject) => {
                options.url = this.baseURL + options.url;
                options.method = options.method || 'GET';
                options.header = {
                    "Authorization": "Bearer " + this.getToken()
                }
                resolve(options)
            })
        },
        // 響應攔截器
        handleResponse(data) {
            return new Promise((resolve, reject) => {
                const [err, res] = data;
                if (res && res.statusCode !== 200) {
                    let msg = res.data.msg || '請求錯誤';
                    uni.showToast({
                        icon: 'none',
                        title: msg
                    })
                    return reject(msg)
                }
                if (err) {
                    uni.showToast({
                        icon: 'none',
                        title: '請求錯誤'
                    })
                    return reject(err)
                }
                return resolve(res.data)
            })
        },
    },
    request(options = {}) {
        return this.config.beforeRequest(options).then(opt => {
            return uni.request(opt)
        }).then(res => this.config.handleResponse(res))
    }
}

2.新建index.js，用來整合所有的接口

import api from './request'
// 水印圖片
function getPhotoImg(data) {
    return api.request({
        method: 'post',
        url: '/jcxywzx/add',
        data: data
    })
}
// 驗證碼
function getCode(data) {
    return api.request({
        method: 'get',
        url: '/api/v1/login/checkCode',
        responseType: 'arraybuffer',
        data: data
    })
}
// 登錄
function getLogin(data) {
    return api.request({
        method: 'post',
        url: '/api/v1/login/auth2',
        data: data
    })
}
// 告警列表
function getAlarm(data) {
    return api.request({
        method: 'get',
        url: '/alarm/page',
        data: data
    })
}

export {
    getPhotoImg,
    getCode,
    getLogin,
    getAlarm
}

3.調用接口

import {
        getAlarm
    } from '../../api/index.js'
async getAlarmDataFun() {
                const {
                    code,
                    data,
                    msg
                } = await getAlarm();
