我試圖用這個當前代碼做的是來自服務器。我希望將變數“10”發送給客戶端。從客戶端到服務器，我想發回兩個變數，一個是“10”，另一個是加密訊息。兩者都發送后，我希望服務器解密訊息并將其列印在螢屏上。
您可能想知道為什么我要來回發送十個，這是因為我會將這個Diffie-Hellman 示例與 合并def findkeys()，謝謝您的時間！
uj5u.com熱心網友回復：
您可以在 json 中發送該 var 而不是單個 var 它可以幫助您同時發送超過 1 個資料

客戶 ...
sock.send(b'10' encrypted_message)
服務器
msg = sock.recv(1024)
code = msg[:2]
encrypted_payload = msg[2:]
你是這個意思嗎？
