Django學習（1）一首情詩

　　Django是Python中Web開發的最有代表性的架構之一。本文将簡單介紹如何入門Django開發。

　　首先確定你的linux系統已安裝django子產品。打開Python3,利用以下指令可找到django所在目錄：

>>> import django
>>> print(django.__path__)           

筆者顯示的是：

['/usr/lib/python3/dist-packages/django']           

　　接下來開始django開發！首先切換到django目錄,建立poem項目：

django-admin.py startproject poem           

輸入tree poem,檢視poem項目的樹結構：

在urls.py的urlpatterns清單中添加：

url(r'^$', 'poem.views.output'),           

在/poem/poem檔案夾下，建立views.py檔案，輸入代碼：

from django.http import HttpResponse

def output(request):
    title = "<h1>When You Are Old</h1>"
    author = "<h2>William Butler Yeats</h2>"
    content = """
                 When you are old and grey and full of sleep,<br/>
                 And nodding by the fire, take down this book,<br/>
                 And slowly read, and dream of the soft look<br/>
                 Your eyes had once, and of their shadows deep;<br/>
                 How many loved your moments of glad grace,<br/>
                 And loved your beauty with love false or true,<br/>
                 But one man loved the pilgrim soul in you,<br/>
                 And loved the sorrows of your changing face;<br/>
                 And bending down beside the glowing bars,<br/>
                 Murmur, a little sadly, how love fled<br/>
                 And paced upon the mountains overhead<br/>
                 And hid his face amid a crowd of stars.<br/>
               """
    return HttpResponse([title, author, content])           

進入poem檔案夾，輸入指令：

python3 manage.py runserver 8000           

　　打開浏覽器，輸入localhost:8000，頁面如下圖：

　　

　　這樣我們就完成了一個簡單的django項目的開發。期待下期分享~~
