小程序ajax网络请求类封装携带token

代码

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,
}

使用
request.GET(接口地址, '参数',成功回调函数,失败回调函数）
先引入请求类

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);
                })
        }
 
    }
