Lea*_*ner 48 python basehttpserver
我正在尝试制作BaseHTTPServer程序.我更喜欢使用Python 3.3或3.2.我发现该文档很难理解导入的内容,但尝试更改导入:
from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer
至:
from http.server import BaseHTTPRequestHandler,HTTPServer
然后导入工作和程序启动并等待GET请求.但是当请求到达时会引发异常:
File "C:\Python33\lib\socket.py", line 317, in write return self._sock.send(b)
TypeError: 'str' does not support the buffer interface
问题:是否有一个版本的BaseHTTPServer或http.server与Python3.x开箱即用,或者我做错了什么？
这是我尝试在Python 3.3和3.2中运行的"我的"程序:
#!/usr/bin/python
# from BaseHTTPServer import BaseHTTPRequestHandler,HTTPServer
from http.server import BaseHTTPRequestHandler,HTTPServer
PORT_NUMBER = 8080
# This class will handle any incoming request from
# a browser
class myHandler(BaseHTTPRequestHandler):
# Handler for the GET requests
def do_GET(self):
print ('Get request received')
self.send_response(200)
self.send_header('Content-type','text/html')
self.end_headers()
# Send the html message
self.wfile.write("Hello World !")
return
try:
# Create a web server and define the handler to manage the
# incoming request
server = HTTPServer(('', PORT_NUMBER), myHandler)
print ('Started httpserver on port ' , PORT_NUMBER)
# Wait forever for incoming http requests
server.serve_forever()
except KeyboardInterrupt:
print ('^C received, shutting down the web server')
server.socket.close()
该程序部分在Python2.7中工作,但在2-8个请求后给出了此异常:
error: [Errno 10054] An existing connection was forcibly closed by the remote host

您在python 3.xx中的程序开箱即可使用 - 除了一个小问题.问题不在您的代码中,而是在您编写这些行的位置:
self.wfile.write("Hello World !")
你试图在那里写"字符串",但字节应该去那里.所以你需要将你的字符串转换为字节.
在这里,查看我的代码,它与您几乎完全相同并且完美运行.它用python 3.4编写
from http.server import BaseHTTPRequestHandler, HTTPServer
import time
hostName = "localhost"
hostPort = 9000
class MyServer(BaseHTTPRequestHandler):
def do_GET(self):
self.send_response(200)
self.send_header("Content-type", "text/html")
self.end_headers()
self.wfile.write(bytes("<html><head><title>Title goes here.</title></head>", "utf-8"))
self.wfile.write(bytes("<body><p>This is a test.</p>", "utf-8"))
self.wfile.write(bytes("<p>You accessed path: %s</p>" % self.path, "utf-8"))
self.wfile.write(bytes("</body></html>", "utf-8"))
myServer = HTTPServer((hostName, hostPort), MyServer)
print(time.asctime(), "Server Starts - %s:%s" % (hostName, hostPort))
try:
myServer.serve_forever()
except KeyboardInterrupt:
pass
myServer.server_close()
print(time.asctime(), "Server Stops - %s:%s" % (hostName, hostPort))
请注意我使用"UTF-8"编码将它们从字符串转换为字节的方式.在程序中进行此更改后,您的程序应该可以正常工作.
你可以这样做:
self.send_header('Content-type','text/html'.encode())
self.end_headers()
# Send the html message
self.wfile.write("Hello World !".encode())

无论谁为 http.server 编写了 python 3 文档，都没有注意到这一变化。2.7 文档在顶部指出“注意 BaseHTTPServer 模块已合并到 Python 3 中的 http.server 中。在将源代码转换为 Python 3 时，2to3 工具将自动调整导入。”
