web端导入证书、https代理即可解决大部分需求，但是，有些app需要处理ssl pinning验证。
废话不多说。frida处理ssl pin的步骤大体如下。
- 安装python3.x,并在python环境中安装frida：
pip install frida
pip install frida-tools
- 下载frida-server，并使用adb命令push到/data/local/tmp目录下,并运行：
adb push frida-server /data/local/tmp
chmod 777 ./frida-server
./frida-server
注意：此处的 f r i d a − s e r v e r 和 f r i d a 的版本号必须要一致，否则会提示如下错误： \color{red}注意：此处的frida-server和frida的版本号必须要一致，否则会提示如下错误： 注意：此处的frida−server和frida的版本号必须要一致，否则会提示如下错误：
frida-server下载地址：https://github.com/frida/frida/releases
- 执行如下命令，即可hook并绕过app对ssl pin的检测：
frida -U -f packagename -l ./ssl.js --no-pause
ssl.js内容：

4.XUtils
5.httpclientandroidlib
6.JSSE

8.Apache Http client (support partly)
9.OpenSSLSocketImpl
10.TrustKit
11.Cronet

当然，除了上述步骤，可能还需要：导入根证书，设置代理等。
可能会用的命令：
显示cpu信息：
cat /proc/cupinfo
adb shell getprop ro.product.cpu.abi
查看frida可以ssl pin的进程：
frida-ps -U
tcpdump命令抓包：
tcpdump -i wlan0 -s 0 -w /sdcard/test.pcap
