使用BaseHTTPRequestHandler编写响应主体 [英] Writing response body with BaseHTTPRequestHandler
问题描述
我正在使用Python 3.2.2进行一些操作，并希望编写一个简单的Web服务器来远程访问一些数据.这些数据将由Python生成，因此我不想使用SimpleHTTPRequestHandler，因为它是文件服务器，而是我自己的处理程序.
I'm playing a little with Python 3.2.2 and want to write a simple web server to access some data remotely. This data will be generated by Python so I don't want to use the SimpleHTTPRequestHandler as it's a file server, but a handler of my own.
我从互联网上复制了一些示例，但由于响应输出流拒绝写正文内容而被困住了.
I copied some example from the internet but I'm stuck because the response outputstream refuses to write the body content.
这是我的代码:
import http.server
import socketserver
PORT = 8000
class MyHandler(http.server.BaseHTTPRequestHandler):
def do_HEAD(self):
self.send_response(200)
self.send_header("Content-type", "text/html")
self.end_headers()
def do_GET(self):
self.send_response(200)
self.send_header("Content-type", "text/html")
self.end_headers()
print(self.wfile)
self.wfile.write("<html><head><title>Title goes here.</title></head>")
self.wfile.write("<body><p>This is a test.</p>")
# If someone went to "http://something.somewhere.net/foo/bar/",
# then s.path equals "/foo/bar/".
self.wfile.write("<p>You accessed path: %s</p>" % self.path)
self.wfile.write("</body></html>")
self.wfile.close()
try:
server = http.server.HTTPServer(('localhost', PORT), MyHandler)
print('Started http server')
server.serve_forever()
except KeyboardInterrupt:
print('^C received, shutting down server')
server.socket.close()
编写响应正文的正确代码应该是什么?
What should be a correct code for writing the response body?
非常感谢.
错误是:
...
File "server.py", line 16, in do_GET
self.wfile.write("<html><head><title>Title goes here.</title></head>")
File "C:\Python32\lib\socket.py", line 297, in write
return self._sock.send(b)
TypeError: 'str' does not support the buffer interface
推荐答案
Python3中的字符串与Python 2.x中的字符串不同.使用
In Python3 string is a different type than that in Python 2.x. Cast it into bytes using either
self.wfile.write(bytes("<html><head><title>Title goes here.</title></head>/html>","utf-8"))
或
self.wfile.write("<html><head><title>Title goes here.</title></head></html>".encode("utf-8"))
