目标网址：人口流动态势网
进入网站。尽量选择比较靠前的时间，因为最新的数据还没有展示出来
我们的需求就是获取流入来源城市和其所占的比例。
抓包分析，
发现响应的数据全被加密了，内容如下：

这种加密的和我们上次做的那个企名片案例比较类似，只不过这个是全部都加密了，说一个可能不太成熟的经验，像这种以==结尾的一般都是base64加密，我们可以用base64解析网站验证一下，这种解析网站有很多，直接百度都能找到，我这里用的是Base64.us，把加密数据粘贴，点击解码之后：
可以看到结果转成了json格式的字符串，可以断定这是base64加密。接下来我们直接开始定位加密js。
2. 定位加密js
还记得上个企名片那个案例吗？那个是直接搜索encrypt_data关键词定位到了一个JSON.parse函数，我们这种可以直接全局搜索json.parse，
敏感的你可能一眼就能看到那个加密相关的js，再搜一下进去
扣下来，
function dataDecode(data){
var base = new Base64();
var d = JSON.parse(base.decode(data));
var key = 'UVJgCE+OFIff3hK5BT5sPBbGZzjR6FwntjSCwOA9tUQ=';
var key1 = CryptoJS.enc.Base64.parse(key);
var iv1 = CryptoJS.enc.Base64.parse(d.iv);
var decrypted=CryptoJS.AES.decrypt(d.value,key1,{
iv : iv1,
mode : CryptoJS.mode.CBC,
padding : CryptoJS.pad.Pkcs7
});
var d = decrypted.toString(CryptoJS.enc.Utf8);
return JSON.parse(d);
}
3. 编写python程序一边调试一边补充js代码
开始编写python代码尝试解密，加密数据是正常的get请求，没有一点问题，这里不再进行编写get请求拿到加密数据了，我们直接用抓包拿到的加密数据测试：

get_decode(data)
初次运行python代码，出现以下报错：
很明显它说咱们没有定义base64，我们继续回到js,打上断点调试；
进入base64函数，抠下来js

继续执行python代码，又报错：
二话不说继续去抠js,
我们点开后面的parse方法就会直接进入cryptojs文件，大致看了一下从第19行开始定义的该方法，
直到末尾：
好像都跟它相关，嫌麻烦不必再纠结这玩意儿，直接拿下来(19-5983行)，js太长这里就不贴了。
再次调试：
对比一下原网页：
可以看到那些比例百分数已经可以正常显示了。
接下来我们只需要把source_city的值换成正常的值就行，继续调试：
把citylist copy下来，放到json.cn解析一下：
可以看到，每一个城市都有一个对应编码，键值对应，接下来了就看想怎么写了，我把我的贴一下仅供参考：
