本文档详细介绍了如何在Django环境下实现一个简单的FTP服务。从创建工程开始，依次介绍了修改models.py、views.py、添加模板文件、更新settings.py和urls.py的步骤，最后通过运行服务器并访问http://127.0.0.1:8000来验证FTP服务的运行。

目标环境在d:/web/

1. 建立工程

D:\web>django-admin startproject ftp

D:\web>python manage.py startapp sample

2.修改sample/models.py添加对象

class PathItem:
    name = ""
    parent = ""
    url = ""

    def __init__(self, name, parent):
        self.name = name
        self.parent = parent
        self.url = "folder/" + os.path.join(parent, name)


class FileItem:
    name = ""
    parent = ""
    url = ""
    canRead = False

    def __init__(self, name, parent):
        self.name = name
        self.parent = parent
        self.url = "file/" + os.path.join(parent, name)

3.修改views.py

def index(request):
    current = 'd:/'
    context_dic = {}
    context_dic['current'] = current
    ps = os.listdir(current)
    path = []
    file = []
    for n in ps:
        v = os.path.join(current, n)
        if os.path.isdir(v):
            p = PathItem(n, current)
            path.append(p)
        else:
            f = FileItem(n, current)
            file.append(f)

    context_dic['path'] = path
    context_dic['file'] = file
    return render(request, 'index.html', context_dic)

def show_folder(request, url):
    current = url
    context_dic = {}
    context_dic['current'] = current
    ps = os.listdir(current)
    path = []
    file = []
    for n in ps:
        v = os.path.join(current, n)
        if os.path.isdir(v):
            p = PathItem(n, current)
            path.append(p)
        else:
            f = FileItem(n, current)
            file.append(f)

    #context_dic['parent'] = os.path.pardir(url)
    context_dic['path'] = path
    context_dic['file'] = file
    return  render(request, 'index.html', context_dic)

4.添加sample\templaste\index.html

<html>
<head>
    <title>Title</title>
</head>
    {% if current %}
    <h1>
        {{ current}}
    </h1>
    <br>
        {% if parent %}
        <a href="{{ parent }}">../</a>
        {% endif %}
        {% if path %}
            {% for p in path %}
            <a href="{{p.name}}">{{  p.name }}</a>
            </br>
            {% endfor %}
        {% endif %}
        <p>-----</p>
        {% if file %}
            {% for f in file %}
                {% if f.canRead %}
                    <a href="{{ f.url }}">{{ f.name }}</a></br>
                {% else %}
                    {{ f.name }}</br>
                {% endif %}
            {% endfor %}
        {% else %}
        file not exist
        {% endif %}
    </body>
{% endif %}
</html>

5.修改ftp/setting.py

添加app

INSTALLED_APPS = [
    ....,
    'sample',
]

添加模板路径

TEMPLATE_PATH = os.path.join(BASE_DIR, 'sample/template')
TEMPLATES = [
    {
        'DIRS': [TEMPLATE_PATH,]，

6.修改ftp/urls.py

from sample import views

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^folder/(?P<url>.+)/$', views.show_folder),
    url(r'^$', views.index),
]
