1、扫码进行体验
2、源码下载
- 关注微信公众号:《柯作》
- 回复:小程序源码
3、部分源码以http请求为例,把普通的http请求封装成Promise,
import {config} from '../config.js'const tips = {1: '抱歉,出现了一个错误',1005:'appkey无效,请前往https://talelin.com/申请',3000:'期刊不存在'
}
// # 解构
class HTTP{request({url,data={},method='GET'}){return new Promise((resolve, reject)=>{this._request(url,resolve,reject,data, method)})}_request(url,resolve, reject, data={}, method='GET'){wx.request({url:config.api_base_url + url,method:method,data:data,header:{'content-type':'application/json','appkey':config.appkey},success:(res)=>{const code = res.statusCode.toString()if (code.startsWith('2')){resolve(res.data)}else{reject()const error_code = res.data.error_codethis._show_error(error_code)}},fail:(err)=>{reject()this._show_error(1)}})}_show_error(error_code){if(!error_code){error_code = 1}const tip = tips[error_code]wx.showToast({title: tip?tip:tips[1], icon:'none',duration:2000}) }}export {HTTP}
