查了一下，原来是获取用户信息的接口更新了。
大家可以这么改：
在 pages/index/index.wxml 的清空任务状态上面补充一句
<button open-type="getUserInfo">授权用户信息</button>
然后运行之前点一下授权，就可以正常使用了。
请重启小程序会话，看你命令你应该是配置后没有重启服务
pm2 restart app我发现你在SSH上直接输入.login，这个登陆地址是在小程序上实现的，并不是在SSH上使用！
app.js 里面的代码应为：
// 引用 express 来支持 HTTP Server 的实现
const express = require('express');
// 引用 wafer-session 支持小程序会话
const waferSession = require('wafer-node-session');
// 使用 MongoDB 作为会话的存储
const MongoStore = require('connect-mongo')(waferSession);
// 引入配置文件
const config = require('./config');
// 创建一个 express 实例
const app = express();
// 添加会话中间件，登录地址是 /login
app.use(waferSession({
appId: config.appId,
appSecret: config.appSecret,
loginPath: '/login',
store: new MongoStore({
url: `mongodb://${config.mongoUser}:${config.mongoPass}@${config.mongoHost}:${config.mongoPort}/${config.mongoDb}`
})
}));
// 在路由 /me 下，输出会话里包含的用户信息
app.use('/me', (request, response, next) => {
response.json(request.session ? request.session.userInfo : { noBody: true });
if (request.session) {
console.log(`Wafer session success with openId=${request.session.userInfo.openId}`);
}
});
// 实现一个中间件，对于未处理的请求，都输出 "Response from express"
app.use((request, response, next) => {
response.write('Response from express');
response.end();
});
// 监听端口，等待连接
app.listen(config.serverPort);
// 输出服务器启动日志
console.log(`Server listening at http://127.0.0.1:${config.serverPort}`);
修改后输入：pm2 restart app
即可
