我写了一个用于验证表单的代码。它在我的本地主机上完美运行。但是,当我在互联网上部署它时,我收到一个错误。以下是整个代码以及与之相关的错误:
import webapp2
from calendar import *
import cgi
form = """
<form method = "post">
<label>Month<input type = "text" name = "mon" value = "%(month)s"></label>
<label>Day<input type = "text" name = "dy" value = "%(day)s"></label>
<label>Year<input type = "text" name = "yr" value = "%(year)s"></label>
<div style="color:red">%(error)s</div>
<br>
<br>
<input type = "submit">
</form>
"""
def escape_html(s):
return cgi.escape(s, quote = True)
class MainHandler(webapp2.RequestHandler):
error = ""
def write_form(self, error, month, day, year):
self.response.write(form %{"error":error, "month":escape_html(month), "day":escape_html(day), "year":escape_html(year)})
def get(self):
#self.response.headers['Content-Type'] = 'text/plain'
self.write_form("", "", "", "")
def post(self):
mon = valid_month(self.request.get("mon"))
dy = valid_day(self.request.get("dy"))
yr = valid_year(self.request.get("yr"))
month = self.request.get("mon")
day = self.request.get("dy")
year = self.request.get("yr")
if not(mon and dy and yr):
self.write_form("Please refill the form with correct data!", month, day, year)
else:
self.redirect("/thanks")
class ThanksHandler(webapp2.RequestHandler):
def get(self):
self.response.write("Thanks for submitting your data!")
app = webapp2.WSGIApplication([('/', MainHandler), ('/thanks', ThanksHandler)], debug=True)
calendar.py
months = ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December']
def valid_month(month):
temp = month.capitalize()
for e in months:
if e == temp:
return e
return None
def valid_day(day):
try:
num = int(day)
except:
return None
if num<=31 and num>0:
return num
else:
return None
def valid_year(year):
if year and year.isdigit():
num = int(year)
if num>1900 and num<2020:
return num
这是我在互联网上传后得到的错误:
内部服务器错误
服务器出错或无法执行请求的操作。

任何人都可以帮我吗?我现在被困在这3天了。无论我尝试用我的代码做什么,我仍然无法让它在互联网上运行。提前谢谢!
答案 0 :(得分:3)
不熟悉GAE,但可能与导入包的顺序有关。
尝试更改
from calendar import *
到
from .calendar import *
在第一种情况下,它可能正在导入系统日历包。在第二种情况下,您要求它导入本地包(您的calendar.py)。
