小程序自己封装请求

var app = getApp();
var host = app.globalData.appServer

function json2Form(json) {
    var str = [];
    for (var p in json) {
        str.push(encodeURIComponent(p) + "=" + encodeURIComponent(json[p]));
    }
    return str.join("&");
}

function _get(params) {

    if (params.flag) {
        wx.showLoading({
            title: '加载中',
            mask: true,
        })
    }
    var gets = params.data
    var url = params.url + (gets ? '?' : '');
    if (params.data) {
        url = url + json2Form(gets)
    }
    wx.request({

        method: 'GET',
