1.自定义分词工具
app/templatetags/custom.py

# _*_ coding:utf-8 _*_
# __author__ == ‘jack‘
# __date__ == ‘2020-12-31 9:03 PM‘

import jieba
from django import template
from app.consts import SensitiveWord


register = template.Library()


@register.filter(name=deep_check_message)
def deep_check(value):
    # 只屏蔽关键词,替换为 * 号
    cut_message = jieba.lcut(value)
    new_message = []
    for m in cut_message:
        if m in SensitiveWord:
            new_message.append(*)
        else:
            new_message.append(m)
    if new_message:
        return ‘‘.join(new_message)
    return value


@register.filter
def sample_check(value):
    # 自定义的关键词过滤器
    cut_message = jieba.lcut(value)
    print(cut_message)
    print(SensitiveWord)
    check = list(set(cut_message) & set(SensitiveWord))

    if len(check) != 0:
        return 该消息涉及违禁词汇,已被屏蔽
    return value


@register.filter
def add_message_year(value, year):
    return {} {}.format(value, year)

2.自定义关键词

app/consts.py

# _*_ coding:utf-8 _*_
# __author__ == ‘jack‘
# __date__ == ‘2020-12-31 8:28 PM‘

from enum import Enum


class MessageType(Enum):
    info = "info"
    warning = "warning"
    error = "error"
    danger = "danger"


MessageType.info.label = 信息
MessageType.warning.label = 警告
MessageType.error.label = 错误
MessageType.danger.label = 危险

MessageType.info.color = green
MessageType.warning.color = orange
MessageType.error.color = gray
MessageType.danger.color = red

SensitiveWord = [天气, 坏人, 不开心]

3.视图

app/views.py

# coding:utf-8

from django.views.generic import View
# from django.http import HttpResponse
from django.shortcuts import render
from .consts import MessageType


class LessionThree(View):

    TEMPLATE = three.html

    def get(self, request, message_type):

        data = {}

        try:
            message_type_obj = MessageType[message_type]
        except Exception as e:
            data[error] = 没有这个消息类型{}.format(e)
            return render(request, self.TEMPLATE, data)
        message = request.GET.get(message, ‘‘)

        if not message:
            data[error] = 消息不能为空
            return render(request, self.TEMPLATE, data)

        data[message] = message
        data[message_type] = message_type_obj

        # return HttpResponse(message_type)
        return render(request, self.TEMPLATE, data)

5.自定义模板html页面

templates/three.html

{% load custom %}
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
{% if error %}
    <h3>error {{ error }}</h3>
{% else %}
    <label style="color:{{ message_type.color }}">{{ message_type.label }}</label>
    <span style="color:{{ message_type.color }}">{{ message|deep_check_message|add_message_year:2020 }}</span>
{% endif %}
</body>
</html>

6.路由信息

app/urls.py

# _*_ coding:utf-8 _*_
# __author__ == ‘jack‘
# __date__ == ‘2020-12-29 8:27 PM‘

from django.urls import path
from .views import LessionThree

urlpatterns = [
    path(three/<str:message_type>, LessionThree.as_view(), name="two")
]

 

总路由 message_test/urls.py

from django.contrib import admin
from django.urls import path,include
from app import urls as app_urls

urlpatterns = [
    path(admin/, admin.site.urls),
    path(‘‘, include(app_urls))
]
