使用flask和简单的html写了一个简单的信息课聊天室
from flask import Flask, request
app = Flask(__name__)
msglist = []
@app.route("/", methods=["POST", "GET"])
def root():
global msglist
if request.method == "GET":
ip = request.remote_addr
reqnum = ip[ip.rfind(".")+1:]
user = request.values.get("user")
message = request.values.get("message")
print(reqnum, user, message)
if (user and message) and (not msglist or msglist[0] != (reqnum, user, message)):
msglist.insert(0, (reqnum, user, message))
with open("chat.html", 'r') as f:
text = ""
name = ""
for fornum, user, message in msglist:
text += "<p>%s,%s: %s</p>" % (fornum, user, message)
if not name and reqnum == fornum:
name = user
# 防止老师直接偷看
if ip == "10.10.50.49":
return ""
return f.read() % (name, text)
app.run(host="0.0.0.0", port=8080, debug=False)
