一、网站分析

二、代码

js代码

var JSEncrypt = require('node-encrypt-js')var crypto = require("crypto") // nodejs自带
function md5(s){return crypto.createHash("md5").update(s).digest("hex");
}function fn(e,r) {var t = new JSEncrypt();t.setPublicKey(r);e.sign = md5(JSON.stringify(e))e.timeStamp = new Date().getTime()var s = t.encryptLong(JSON.stringify(e))return s
}
// console.log(md5("123456"))

import requests
import json
import execjs
session = requests.session()
session.headers = {"":""# 请求头自行添加
}
url = "https://ec.minmetals.com.cn/open/homepage/public"
resp = session.post(url)
# print(resp.text)p_url = "https://ec.minmetals.com.cn/open/homepage/zbs/by-lx-page"data = {"businessClassfication": "","dwmc": "","inviteMethod": "","lx": "ZGYS","mc": "","pageIndex": "1"
}f = open('wk.js',mode='r',encoding='utf-8')
js_code = f.read()
f.close()
js = execjs.compile(js_code)
param = js.call("fn",data ,resp.text)
data = {"param":param
}
p_resp = session.post(p_url,json.dumps(data,separators=(',', ':')),headers={"Content-Type":"application/json",
})
print(p_resp.text)
