在python3中運行出錯：
運行結果：
Traceback (most recent call last): File "/usercode/file.py", line 16, in <module> s.send('GET / HTTP/1.1\r\nHost: www.sina.com.cn\r\nConnection: close\r\n\r\n')TypeError: 'str' does not support the buffer interface
這是因為python3對字串做了更改，使得預設字串編碼與python2.7的不同。
所以，使用client_socket.send（data）時，將其替換為client_socket.send（data.encode（））。
當使用data = client_socket.recv（512）擷取資料時，請將其替換為data = client_socket.recv（512）.decode（）
更改後的程式為：
#!/usr/bin/python# -*- coding: utf-8 -*-# 匯入socket庫:import socket# 建立一個socket:s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 建立串連:s.connect(('www.sina.com.cn', 80))s.send(('GET / HTTP/1.1\r\nHost: www.sina.com.cn\r\nConnection: close\r\n\r\n').encode()) ####添加.encode# 接收資料:buffer = []while True: # 每次最多接收1k位元組: d = s.recv(1024).decode("utf8","ignore") #######添加.decode("utf8","ignore") if d: buffer.append(d) else: breakdata = ''.join(buffer)print (data)# 關閉串連:s.close()
