项目中接口使用restful api风格,需要携带token,当http状态码为401时需要重新发起登录,为方便统一管理将小程序网络请求原生接口封装
utils/request.js 请求类
token存在globalData中,默认携带,服务端判断错误时可以登录更新
- /**
- *
- * 网络请求相关操作
- * statusCode为401时跳转到重新登录更新token
- */
-
- //接口地址
- var _api = 'http://www.aaa.com/';
-
- function
- curl(url, data, success, fail, method)
- {
- var token = getApp().globalData.token;
- wx.request({
- url: _api + url,
- header: {
- 'Content-Type': 'application/json',
- 'Authorization': token
- },
- method: method,
- data: data,
- success: function (res) {
- if (res.statusCode == 401) {
- toLogin();
- }
- success(res);
- },
- fail: function (error) {
- fail(error);
- }
- });
- }
-
- /**
- * get方式获取数据
- */
- function _get(url, data, success, fail) {
- curl(url, data, success, fail, 'GET');
- }
-
- function post(url, data, success, fail) {
- curl(url, data, success, fail, 'POST');
- }
-
- function put(url, data, success, fail) {
- curl(url, data, success, fail, 'PUT');
- }
-
-
- function _delete(url, data, success, fail) {
- curl(url, data, success, fail, 'DELETE');
- }
-
- function toLogin() {
- wx.navigateTo({
- url: '/pages/login/login'
- })
- }
-
- module.exports = {
- GET: _get,
- POST: post,
- PUT: put,
- DELETE: _delete,
- URL: _api,
- }
request.GET(接口地址, '参数',成功回调函数,失败回调函数)
- var request = require("../../utils/request.js");
-
- /**
- * 获取幻灯片
- */
- getSlideList() {
- var that = this;
- var slide = cache.cache('slide');
- if (slide) {
- that.setData({
- slideList: slide,
- })
- } else {
- request.GET('slide', '',
- function (res) {
- if (res.data.code == 0) {
- that.setData({
- slideList: res.data.data.data,
- })
- cache.cache('slide',res.data.data.data);
- }
- },function (error) {
- console.log(error);
- })
- }
-
- },
