I'm doing the long-polling pattern with a PHP script and a MySQL database on a server and python script on the client. If the flag in the database is set to 0, the PHP page responds with the id of the tupel. If the request times out, a new request should be started. This is my code and I can't find my mistake:
gotID = False
ID = 0
while gotID == False:
f = requests.get("http://example.de/ajax_backend.php")
print("status: " + str(f.status_code))
print("content: " + f.text)
if int(f.status_code) == 200:
gotID = True
ID = f.text
If I run the code like this i get this output. First the flag was set to 1, then in the middle i changed the flag to 0:
I think there is an error in the if
statement, but I can't find it. Can you help me?
I now created a working code:
gotID = None
ID = 0
while not gotID:
f = requests.get("http://example.de/ajax_backend.php")
print("status: " + str(f.status_code))
print("content: " + f.text)
try:
ID = int(f.text)
gotID = "samlpe content"
except ValueError:
gotID = None
But i still don't know why my code above don't works.
