这段时间研究了下裁判文书网的反爬策略感觉挺有意思的，这里给大家分享一下
思路分析
我们先在裁判文书网上随便搜索点东西，我这里搜的是"经济犯罪"，可以看到返回了很多页的数据，我们点击下一页然后看下请求
观察上图中的参数，并试着在postman中调用一下试试看
可以看到直接能发送成功，并且修改pageNum值之后仍然能够正常拿到返回结果，可是返回结果是加密的。那我们先来研究下如何进行解密。
观察可以看到返回结构如下
{
"code": 1,
"description": null,
"secretKey": "I7NGzDPxwy01xcpHGrNnZcDo",
"result": ".........",
"success": true
}
其中secretKey似乎是秘钥，尝试搜索secretKey
搜索后可以看到在website.js中似乎有解密的代码(上图中4位置)。我们在website.js的245行(上图中4位置)打上断点，然后在网站上点击翻页，可以发现网页会在断点处停住，然后解密函数，可以找到解密方法的位置
观察此函数可以发现此解密方法在js中有完整代码，加解密代码压缩后如下

我们随便找个网页把这段代码贴进去，并把刚刚postman中得到的result和secretKey填进去，可以发现解密代码会报错
可以看到是没有formatDate属性。点击我上图框的位置找到报错的js
可以看到在是因为取不到 $.webSite.formateDate。现在我们返回文书网的website.js搜索formateDate，可以看到formateDate函数
那么我们修改js代码，把
iv: function() {
return $.WebSite.formatDate(new Date(), "yyyyMMdd")
},
改为
iv: function() {
return myformatDate(new Date(), "yyyyMMdd")
},
并在js中添加如下方法
function myformatDate(v, format) {
if (!v)
return "";
var d = v;
if (typeof v === 'string') {
if (v.indexOf("/Date(") > -1)
d = new Date(parseInt(v.replace("/Date(", "").replace(")/", ""), 10));
else
d = new Date(Date.parse(v.replace(/-/g, "/").replace("T", " ").split(".")[0]));
// 用来处理出现毫秒的情况，截取掉.xxx，否则会出错
} else if (typeof v === "number") {
d = new Date(v);
}
var o = {
"M+": d.getMonth() + 1,
// month
"d+": d.getDate(),
// day
"h+": d.getHours(),
// hour
"m+": d.getMinutes(),
// minute
"s+": d.getSeconds(),
// second
"q+": Math.floor((d.getMonth() + 3) / 3),
// quarter
"S": d.getMilliseconds()// millisecond
};
format = format || "yyyy-MM-dd";
if (/(y+)/.test(format)) {
format = format.replace(RegExp.$1, (d.getFullYear() + "").substr(4 - RegExp.$1.length));
}
for (var k in o) {
if (new RegExp("(" + k + ")").test(format)) {
format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
}
}
return format;
}
更改后完成js代码如下

我们再随便找个网页，并调用DES3.decrypt(“xxx”,“xxx”)，可以发现已经能解密成功了
ok，到这里解密就完成了。现在我们回过头来看一下请求，再次在postman中执行刚刚的请求，可以发现已经不通了
经过与成功的请求对比可以发现参数ciphertext、__RequestVerificationToken发生了改变，那么我们研究下这两个参数是怎么生成的。
经过全局搜索可以发现ciphertext生成的位置
可以发现strToBinary.js就是用来生成ciphertext的。
全局搜索__RequestVerificationToken很容易发现生成位置
通过断点调试可以找到random函数
到这里请求已经已经能发送成功并解密成功了，但这个返回的只是文书的简略信息以及docId，并没有文书全部内容，因此我们还需要再分析如何通过返回的docId来爬取文书全文。鉴于获取文书全文的加解密方法都一致我这里不做赘述，需要的同学可以直接代码
思路整理
1、登陆网站获取cookie
2、通过上述函数计算出ciphertext与__RequestVerificationToken的值，并封装请求
3、拿到响应后通过上述解密函数进行数据解密拿到docId
4、通过docId获取文书全部内容
Coding

在应用启动时加载js
private static Invocable inv;
static {
try {
String jsScript = FileUtil.readString(new File("/Users/kevindai/Downloads/entry.js"), Charset.defaultCharset());
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
engine.eval(jsScript);
inv = (Invocable) engine;
} catch (ScriptException e) {
e.printStackTrace();
}
}
编写生成参数以及解密代码
private String geneToken() throws Exception{
return (String)inv.invokeFunction("geneToken","24");
}
private String geneCiphertext() throws Exception{
return (String)inv.invokeFunction("cipher");
}
private String decode(String value,String key) throws Exception{
return (String)inv.invokeFunction("decrypt",value,key);
}
编写docId爬取代码

我这里只是写了个demo，所以cookie是直接从网站上复制的，需要用在生产环境的同学可以先用selenium之类的框架模拟登陆拿到cookie，这样可以实行全流程的自动化

ok，到这里代码就全部编写完成了，经过测试爬取是没问题的。此数据源用于一些风控场景还是挺有效的，希望能帮到你们。如果大家觉得什么网站加密很有趣也可以发给我研究一下啊
