還要會搜尋（回覆比較慢）

1. 手機中執行 tcpdump
tcpdump -i any -s 0 -w /sdcard/Download/capture.pcap

2. 手機沒有tcpdump的
下載地址https://www.androidtcpdump.com/android-tcpdump/downloads
adb push tcpdump /data/local/tmp/ (如果遇到許可權不夠的，先push到sdcard/ 再移動過去)

2.1在手機中執行給許可權
chmod 777 tcpdump

2.2繼續執行1
./tcpdump -i any -s 0 -w /sdcard/Download/capture.pcap
 

hook app拿到sslkey

frida -U -f package -l ./sslkeyfilelog.js --no-pause

將/sdcard/Download/capture.pcap pull 到pc

儲存frida輸出的列印資訊到sslkey.txt（還沒做到一鍵傻瓜化）

設定Wireshark tls

[b]編輯--> 首選項--> Protocols--> TLS

選擇到tls 後將之前的sslkey.txt匯入下。 再使用下前面的過濾命令， 正常情況下， 現在就能正常看到了。

設定完這個， 就也和我一樣能看到教學圖了， 一下子友好很多。

致敬大佬

@菱志漪 其實要感謝菱志漪大佬，沒有他遇到的問題，我就不會深入去看研究這個問題，還要感謝@肉師傅， 沒有陳老師通俗易懂的講解， 我壓根找不到北。 【手動撒花~~~】

錯誤補充

---2021-4-21更新
需要在在安卓8.0， frida版本12.8.0， 其他版本沒測試過， 如果遇到錯誤， 就跟我一樣。 感謝@wddzz 提供的問題。
