1、寻找数据接口 2、对比payload寻找可疑参数 3、多次重放请求确定反爬参数 这一块也就是说这三个参数咱们都需要进行处理
4、下xhr断点并堆栈回溯寻找加密位置 _对象值
5、进入g.default()函数内部 6、找到webpack加载器 7、扣出加载器 8、测试加载器并补window全局变量 var get_sign;

get_sign(test)9、补充加载模块 去掉重复 最终扣出的模块 一共5个 后续还会有一个是生成另一个参数的 大家往后看
10、生成sign逻辑 11、reqtranceno参数的寻找 进入h.default 将这个放到加载器中直接调用获取生成的值
12、还原python逻辑 总结
这是一个webpack的经典案例难度适中主要是要理解webpack的流程。对应三个参数该如果获取先后的逻辑分析清楚就会非常简单
最后
随着本篇文章的结尾爬虫阶段就正式结束了
在此感谢大家的支持接下来我会持续更新OpenCV计算机视觉开发或C语言基础
