一、创建config.js(判断开发环境)

if (process.env.NODE_ENV === 'development') {
    // 开发环境
    url_config = 'http://'
} else {
    // 生产环境
    url_config = 'http://'
}

export default url_config

二、创建request.js

import urlConfig from './config.js'
import { getToken } from '@/utils/auth.js'
const request = {}
const headers = {}
request.globalRequest = (url, method, data) => {
    if (!data) {
        data = {}
    }
    if (getToken()) {
        headers['Authorization'] = 'Bearer ' + getToken() || ''
    }
    console.log(data);
    return new Promise((resolve, reject) => {
        uni.request({
            url: urlConfig + url,
            method: method,
            data: data,
            sslVerify: false,
            dataType: 'json',
            header: headers,
            timeout: 5 * 1000
        }).then(res => {
            console.log("当前接口调用==: " + urlConfig + url);
            const new_data = res[1].data
            console.log(new_data)
            if (new_data.code && new_data.code == 200) {
                resolve(new_data)
            } else {
                uni.showToast({
                    title: new_data.msg,
                    icon: 'none',
                    duration: 3 * 1000
                })
                reject(new_data.msg || '请求失败,请重新尝试')
            }
        }).catch(res => {
            uni.showModal({
                title: '提示',
                content: '请求失败,请重新尝试',
                showCancel: false
            })
            reject(res.msg || '请求失败,请重新尝试')
        })
    })
}
export default request

auth.js

const TokenKey = ''

export function getToken () {
  return uni.getStorageSync(TokenKey)
}

export function setToken (accessToken) {
    uni.setStorage({
        key: TokenKey,
        data: accessToken
    })
}

export function removeToken () {
  uni.clearStorageSync()
}

三、封装接口api

/* 
*  login.js
*/
import request from '@/utils/request.js'

export function login(params) {
    return request.globalRequest(`/login`, 'POST', params)
}

四、调用

import { login } from '@/api/login.js'
login(params).then(res => {
  // 成功
}).catch(error => {
  // 失败
})
