I am trying to create a local HTTP server for Flask.
Server starts successfully but when i try to run the localhost:5000 in web browser i get this error
class webserverhandler(BaseHTTPRequestHandler):
def do_GET(self):
try:
if self.path.endswith("/"):
self.send_response(200)
self.send_header('Content-Type','text/html')
self.end_headers()
output=""
output+="<html><body>Hello</body></html>"
self.wfile.write(output)
print (output)
return
except IOError:
self.send_error(404,"File Not Found %s" % self.path)
def main():
try:
port=5000
server=HTTPServer(('',port),webserverhandler)
print ("webserver running on %s" % port)
server.serve_forever()
except KeyboardInterrupt:
server.socket.close()
----------------------------------ERROR-----------------------------------------

TypeError: a bytes-like object is required, not 'str'
anyone can help me?

You can encode your output variable into a bytes_object like this:
self.wfile.write(output.encode())
It seems you are using Python3, where string literals are unicode (str) objects by default. Use the b-prefix
output = b""
output += b"<html><body>Hello</body></html>"
to create a bytes-object.
