一、确定逻辑
获取的数据复制给 window.__DATA__
全局搜索，确定位置
跟进去发现，在这个位置生成数据
验证一下
二、调试
巴拉巴拉
三、搭建解密服务
var r = "WKVZcEaRd7/………………";var i = 16
var Q = 4096
var p = {start: 2,end: 7
}
var K = {}…………………………………………………………………………………………………………………………………………………此处省略N字……………………………………………………………………………………………………………………………………………………………………………………function decrypt(r) {var a = encry2arr_from(r, "base64") // 0,s = Math.max(Math.floor((a.length - 2 * i) / 3), 0) // 40,u = a_slice(a, s, s + i); // 41a = concat([a_slice(a, 0, s), a_slice(a, s + i)]); // 43 45 47var c_data = hash(concat([u, encry2arr_from("")])); // 49 67 69var l = {}l[c_data] = avar data = n_n((l = {}, l[c_data] = a, l))// console.log(data)// console.log(data.payload.items[0])var d_temp = data.payload.itemsvar ret_val = JSON.stringify(d_temp)return ret_val
}function get_page(arg){console.log(arg)return decrypt(arg)
}module.exports = {get_page
}
spider_server.js
var express = require('express');
var douban = require('./douban');
var app = express();
const multipart = require('connect-multiparty')
const multipartyMiddleware = multipart()app.post('/db', multipartyMiddleware, (req, res) => {console.log(req)var result = douban.get_page(req.body.p1)res.send(result)
})app.listen(23341, function () {
})
