Writing response body with BaseHTTPRequestHandler
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.
I copied some example from the internet but I'm stuck because the response outputstream refuses to write the body content.
This is my code:
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()
What should be a correct code for writing the response body?
Thanks a lot.
Edit:
The error is:
...
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
Answer
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"))
or
self.wfile.write("<html><head><title>Title goes here.</title></head></html>".encode("utf-8"))
