运行结果:

在python3中运行出错:
运行结果:
Traceback (most recent call last): File "/usercode/file.py", line 16, ins.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
这是因为python3对字符串做了更改,使得默认字符串编码与python2.7的不同。
所以,使用client_socket.send(data)时,将其替换为client_socket.send(data.encode())。
当使用data = client_socket.recv(512)获取数据时,请将其替换为data = client_socket.recv(512).decode()
更改后的程序为:
#!/usr/bin/python # -*- coding: utf-8 -*- # 导入socket库: import socket # 创建一个socket: s = socket.socket(socket.AF_INET, socket.SOCK_STREAM) # 建立连接: 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 # 接收数据: buffer = [] while True: # 每次最多接收1k字节: d = s.recv(1024).decode("utf8","ignore") #######添加.decode("utf8","ignore") if d: buffer.append(d) else: break data = ''.join(buffer) print (data) # 关闭连接: s.close()
运行结果:
