全局封装 ajax ，方便添加默认参数 ，判断本地存储信息 ，登录情况

// 基准路径

const baseUrl = ‘http://www.xxx.com/xxxx/methods/’

//获取countryCode 和 exchange_rate

function getExrate(url, method, header={}) {

wx.request({

url: baseUrl + url,method: "GET",data:{},header,success: res => { if(res.statusCode == 200){//设置countryCode 和 exchange_ratelet countryCode = res.data.data.countryCode;let exchange_rate = res.data.data.exchange_rate;wx.setStorage({key: "countryCode",data: countryCode})wx.setStorage({key: "exchange_rate",data: exchange_rate})}wx.hideLoading()},fail: err => {console.log(err);}

})

}

// 1.0 返回一个 promise 对象

function request(url, method = ‘GET’, data = {}, header = {}) {

//获取本地存储信息

try {

const res = wx.getStorageInfoSync()//已经登录  添加user_idif (res.hhauseUser){let hhauseUser = JSON.parse(res.hhauseUser)data.user_id = hhauseUser.user_id}//添加来源data.source = 'WeChat'if (!res.countryCode || !res.exchange_rate){getExrate('system.getExrate', method)}//添加地区编码data.countryCode = res.countryCode || "CN"//添加汇率data.exchange_rate = res.exchange_rate || "7.0406"//添加版本data.v = '1.0'

} catch (e) {

console.log(e);

}

return new Promise((resolve, reject) => {

wx.showLoading({title: '加载中'})// 2.0 完成逻辑处理wx.request({url:  url,method: method,data: data,header,success: res => { resolve(res)wx.hideLoading()},fail: err => {reject(err)}})

})

}

// 封装一个单独的 get 方法

request.get = function (url, data = {}) {

return request(baseUrl + url, ‘GET’, data)

}

// 封装一个单独的 post 方法

request.post = function (url, data = {}) {

return request(baseUrl + url, ‘POST’, data)

}

// 3.0 暴露给外界

export default request
