cqu-kb's Issues

A wired character `Ò»` caused the program to crash

KeyError: 'Ò»'

This only appears in some special cases. The character may come from the trash website.

部分日历软件无法正确读取同时带时区（`TZID`）和`VALUE`属性的时间

比如锤子日历（当然这是它们的锅）。
另见 collective/icalendar#75 。
在一个同类项目里为了兼容这部分软件，我使用了以下 workaround 来把VALUE去掉同时保留时区。

from icalendar import vDDDTypes
def add_datetime(component, name, time):
    vdatetime = vDDDTypes(time)
    if 'VALUE' in vdatetime.params and 'TZID' in vdatetime.params:
        vdatetime.params.pop('VALUE')
    component.add(name, vdatetime)
...

add_datetime(event, 'dtstart', event_start_datetime)
add_datetime(event, 'dtend', event_end_datetime)

关于几处不合乎 RFC 5545 的地方

VEVENT中dtstamp和uid不可省略（https://icalendar.org/iCalendar-RFC-5545/3-6-1-event-component.html ）（另见 zombie110year/cli_cqu#9 ）
TZID涉及的时区需要有对应的VTIMEZONE（https://icalendar.org/iCalendar-RFC-5545/3-2-19-time-zone-identifier.html ）（另见 zombie110year/cli_cqu#11 ）

新系统

换了新的选课系统，用的是统一认证号了，失效了

Potential security problems

Here are potential problems:

The public subscription server is not using HTTPS, besides the default HTTP method is GET. It can be easily MITM attack and cause user's credential leak.
This repo is not using any encryption with user's password, it can be stolen by malwares easily.

Maybe you can consider:

Using nginx/caddy to provide HTTP service with reliable HTTPS, using this repo as an upstream.
Provide user graphical interface (web page frontend) for user. In this way you can change GET method to POST to ensure the security. (Credential information should not using GET method to submit)
Implementing master-key mechanism or not saving password to protect user's password.
