使用promise封装小程序的请求：
function request(url, data = {}, method = "POST", header = "application/x-www-form-urlencoded") {
wx.showLoading({
title: '加载中...',
});
return new Promise(function (resolve, reject) {
wx.request({
url: url,
data: data,
method: method,
header: {
'Content-Type': header,
'X-Nideshop-Token': wx.getStorageSync('token')
},
success: function (res) {
wx.hideLoading();
if (res.statusCode == 200) {
if (res.data.errno == 401) {
wx.navigateTo({
url: '/pages/auth/btnAuth/btnAuth', // 登录授权页面
})
} else {
resolve(res.data);
}
} else {
reject(res.errMsg);
}
},
fail: function (err) {
reject(err)
}
})
});
}
