加载脚本

# Connect Frida to a locally-running Calculator.app and load calc.js
$ frida Calculator -l calc.js

# The code in calc.js has now been loaded and executed. Any changes will be reloaded automatically
[Local::ProcName::Calculator]->

# Manually reload it from file at any time
[Local::ProcName::Calculator]-> %reload
[Local::ProcName::Calculator]->

启用兼容 Node.js 的调试器

# Connect Frida to a locally-running Calculator.app
# and load calc.js with the debugger enabled
$ frida Calculator -l calc.js --debug

Debugger listening on port 5858
# We can now run node-inspector and start debugging calc.js
