Django——博客项目

博客项目

目前的目标是构建一个基于Django的前后端完整的博客系统，首先对项目流程整理如下：

1. 分析需求

1.1. 基于用户认证组件和Ajax实现登录验证

图形验证码核心代码：

模板：

<div class="from-group">
                    <label for="pwd">验证码</label>
                    <div class="row">
                        <div class="col-md-6">
                            <input type="text" class=" form-control" id="valid_code">
                        </div>
                        <div class="col-md-6">
                             <img width="270" height="36" id="valid_code_img" src="/get_validCode_img/" alt="">
                        </div>
                    </div>

视图：

def get_validCode_img(request):
    def get_random_color():
        return (random.randint(0, 255), random.randint(0, 255), random.randint(0, 255))

    # 方式一
    # with open('luffy.png',"rb") as f:
    #     data=f.read()

    # 方式二
    # from PIL import Image
    # img = Image.new('RGB',(270,40),color=get_random_color())
    # with open('validCode.png','wb') as f:
    #     img.save(f,'png')
    # with open('validCode.png',"rb") as f:
    #     data=f.read()
    # return HttpResponse(data)
    # 方式3
    #     from PIL import Image
    #     from io import BytesIO
    #     img = Image.new('RGB',(270,40),color=get_random_color())
    #
    #     f= BytesIO()
    #     img.save(f,'png')
    #     data = f.getvalue()
    #     return HttpResponse(data)
    # 4
    from PIL import Image, ImageDraw, ImageFont
    from io import BytesIO
    img = Image.new('RGB', (270, 40), color=get_random_color())
    draw = ImageDraw.Draw(img)
    pingfang = ImageFont.truetype('static/font/pingfang.ttf', size=28)
    char =str(random.randint(0,9))
    for i in range(5):
        random_num = str(random.randint(0, 9))
        random_low = chr(random.randint(95, 122))
        random_up = chr(random.randint(65, 90))
        random_char = random.choice([random_low,random_num,random_up])
        draw.text((i*50+20, 5), random_char, get_random_color(), font=pingfang)
    f = BytesIO()
    img.save(f, 'png')
    data = f.getvalue()
    return HttpResponse(data)

1.2. 基于forms组件和Ajax实现注册功能

1.3. 设计系统首页（文章列表渲染）

1.4. 设计个人站点页面

1.5. 文章详情页

1.6. 实现文章点赞功能

1.7. 实现文章的评论

　　1.7.1. 文章的评论

　　1.7.2. 评论的评论

1.8. 富文本编辑框和防止xss攻击

2. 设计表结构

 module代码：
