Using sockets but keep getting syntax error.

[kiltedpython]

Just need some basic http stuff but cannot seem to get some hidden syntax error. Any help is appreciated.

Code: Select all

import socket


def http_get(url):
    _, _, host, path = url.split('/', 3)
    addr = socket.getaddrinfo(host, 8060)[0][-1]
    s = socket.socket()
    s.connect(addr)
    s.send(bytes('GET /%s HTTP/1.0\r\nHost: %s\r\n\r\n' % (path, host), 'utf8'))
    while True:
        date = s.recv(100)
        if data:
            print(str(data, 'utf8'), end='')
        else:
            break
    s.close()


def http_post(url):
    _, _, host, path = url.split('/', 3)
    addr = socket.getaddrinfo(host, 8060)[0][-1]
    s = socket.socket()
    s.connect(addr)
    s.send(bytes('POST /%s HTTP/1.0\r\nHost: %s\r\n\r\n' % (path, host), 'utf8'))
    while True:
        date = s.recv(100)
        if data:
            print(str(data, 'utf8'), end='')
        else:
            break
    s.close()

I can't see any reason for a SyntaxError, however on line 12 you have

Code: Select all

date = s.recv(100)

which should be "data"

Also, I'd recommend using the "urequests" library if possible.

Thanks for the spelling fix but still seeing syntax error.

Code: Select all

MicroPython v1.12-2 on 2020-05-01; linux version
Use Ctrl-D to exit, Ctrl-E for paste mode
>>> import pyokuets
>>> http_get(http://192.168.1.8/query/apps)
Traceback (most recent call last):
  File "<stdin>", line 1
SyntaxError: invalid syntax

There is no information on why or what. Just poke and guess?

As far as using urequests; the board that is being used does not have 'upip' or many libs installed by default. Trying to build an image for the board that will have all the libs that would be nice to have but until then going with 'sockets' for this.

You need to surround the argument to http_get in quotes.

Thank you so much. That was the ticket.
