安装配置

说明：配合 ADBGUI 工具，更加高效快捷。

安装配置

注入方式

# spawn方式
frida -U --no-pause -f com.abc.xxx -l xxx.js

# attach方式
frida -U pid -l xxx.js

基础语法

API名称	描述
`Java.use(className)`	获取指定的Java类并使其在JavaScript代码中可用。
`Java.perform(callback)`	确保回调函数在Java的主线程上执行。
`Java.choose(className, callbacks)`	枚举指定类的所有实例。
`Java.cast(obj, cls)`	将一个Java对象转换成另一个Java类的实例。
`Java.enumerateLoadedClasses(callbacks)`	枚举进程中已经加载的所有Java类。
`Java.enumerateClassLoaders(callbacks)`	枚举进程中存在的所有Java类加载器。
`Java.enumerateMethods(targetClassMethod)`	枚举指定类的所有方法。

日志输出

日志方法	描述	说明
`console.log()`	使用JavaScript直接进行日志打印	多用于在CLI模式中，`console.log()`直接输出到命令行界面，使用户可以实时查看。在RPC模式中，`console.log()`同样输出在命令行，但可能被Python脚本的输出内容掩盖。
`send()`	Frida的专有方法，用于发送数据或日志到外部Python脚本	多用于RPC模式中，它允许JavaScript脚本发送数据到Python脚本，Python脚本可以进一步处理或记录这些数据。
