node.js - 用node做微信开发后台，获取access_token报错

问题描述

按照网上教程写的，但是貌似坑比较多，新手不知道哪里出错了，只知道是给一个没有定义的东西挂在属性什么什么的，下面贴出代码，如果不全，我继续贴。报错：

这是目录结构：

下面是g.js

’use strict’var sha1 = require(’sha1’);var Promise = require(’bluebird’);var request = Promise.promisify(require(’request’));var prefix = ’https://api.weixin.qq.com/cgi-bin/’;var api = { accessToken:prefix+’token?grant_type=client_credential’}function Wechat(opts) { var that = this; this.appID = opts.appID; this.appSecret = opts.appSecret; this.getAccessToken = opts.getAccessToken; this.saveAccessToken = opts.saveAccessToken; this.getAccessToken() .then(function (data) {try { data = JOSN.parse(data);}catch(e) { return that.updateAccessToken();}if (that.isValidAccessToken(data)) { Promise.resolve(data);}else { return that.updateAccessToken();} }) .then(function (data) {that.access_token = data.access_token;that.expires_in = data.expires_in;that.saveAccessToken(data); })}Wechat.prototype.isValidAccessToken = function (data) { if (!data || !data.access_token || !data.expires_in) {return false; } var access_token = data.access_token; var expires_in = data.expires_in; var now = (new Date().getTime()) if (now < expires_in) {return true; }else {return false; }}Wechat.prototype.updateAccessToken = function () { var appID = this.appID; var appSecret = this.appSecret; var url = api.accessToken + ’&appid=’ + appID + ’&secret=’ + appSecret; return new Promise(function (resolve, reject) {request({url: url, json: true}).then(function (response) { var data = response[1]; var now = (new Date().getTime()); var expires_in = now + (data.expires_in - 20) * 1000; data.expires_in = expires_in; resolve(data);}) })}module.exports = function (opts) { var wechat = new Wechat(opts); return function *(next) {console.log(this.query)var token = opts.token;var signature = this.query.signature;var nonce = this.query.nonce;var timestamp = this.query.timestamp;var echostr = this.query.echostr;var str = [token, timestamp, nonce].sort().join(’’);var sha = sha1(str);if (sha === signature) { this.body = echostr + ’’;}else { this.body = ’wrong’;} }}

util.js:

’use strict’ var fs = require(’fs’); var Promise = require(’bluebird’); exports.readFileAsync = function (fpath, encoding) {return new Promise(function (resolve, reject) { fs.readFile(fpath, encoding, function (err, content) {if (err) reject(err);else resolve(content); })}) } exports.writeFileAsync = function (fpath, content) {return new Promise(function (resolve, reject) { fs.writeFile(fpath, content, function (err) {if (err) reject(err);else resolve(); })}) }

app.js:

’use strict’var Koa = require(’koa’);var path = require(’path’);var util = require(’./libs/util’);var wechat = require(’./wechat/g’);var wechat_file = path.join(__dirname,’./config/wechat.txt’);var config = { wechat: {appID: ’wxf959acc9ef3df3df’,appSecret: ’a5eaa93a1f0b75e692c0fb88f8ecdd37’,token: ’wuwei’,getAccessToken: function () { return util.readFileAsync(wechat_file);},saveAccessToken: function (data) { data = JSON.stringify(data); return util.writeFileAsync(wechat_file, data);} }}var app = new Koa();app.use(wechat(config.wechat))app.listen(80);console.log(’listening：80’);

问题解答

一个 request 请求结果处理有问题

把g.js 的 第 55 行的request 改成

request({url: url, json: true}, function (error, response, body) { if (!error && response.statusCode === 200) {var data = JSON.parse(body);var now = (new Date().getTime());var expires_in = now + (data.expires_in - 20) * 1000;data.expires_in = expires_in;resolve(data);console.log(data); } else {reject() }});回答2：

request({url: url, json: true}).then(function (response) {console.log(’data-----’,response);var data = response[1];//看是不是这个问题var now = (new Date().getTime());var expires_in = now + (data.expires_in - 20) * 1000;data.expires_in = expires_in;resolve(data); })回答3：

你先看看 response返回是啥再说
