xadmin下設定“use_bootswatch = True”無效

xadmin採用原始碼的方式引入到專案中
在xadmin使用的過程中,設定“use_bootswatch = True”,企圖調出主題選單,顯示更多主題。然而設定了後,發現主題還是預設和bootstrap2,深入跟蹤原始碼,發現/xadmin/plugins/themes.py下的
block_top_navmenu
當use_bootswatch 為True的時候,就會使用httplib2去
http://bootswatch.com/api/3.json
網址獲取主題選單項。但是使用瀏覽器開啟這個網址,http會被替換成https的。httplib2訪問這個https的網址,就會報錯。報錯資訊為:
[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure
這邊使用requests庫來替代httplib2.
1.安裝requests
pip install requests
2.在./xadmin/plugins/themes.py 引入requests
import requests
3.修改block_top_navmenu方法:
def block_top_navmenu(self, context, nodes):
themes = [
{'name': _(u"Default"), 'description': _(u"Default bootstrap theme" ), 'css': self.default_theme},
{'name': _(u"Bootstrap2"), 'description': _(u"Bootstrap 2.x theme"), 'css': self.bootstrap2_theme},
]
select_css = context.get('site_theme', self.default_theme)
if self.user_themes:
themes.extend(self.user_themes)
if self.use_bootswatch:
ex_themes = cache.get(THEME_CACHE_KEY)
if ex_themes:
themes.extend(json.loads(ex_themes))
else:
ex_themes = []
try:
flag = False #假如為True使用原來的程式碼,假如為Flase,使用requests庫來訪問
if flag:
h = httplib2.Http()
resp, content = h.request("http://bootswatch.com/api/3.json", 'GET', '',
headers={"Accept": "application/json", "User-Agent": self.request.META['HTTP_USER_AGENT']})
if six.PY3:
content = content.decode()
watch_themes = json.loads(content)['themes']
else:
content = requests.get("https://bootswatch.com/api/3.json")
if six.PY3:
content = content.text.decode()
watch_themes = json.loads(content.text)['themes']
ex_themes.extend([
{'name': t['name'], 'description': t['description'],
'css': t['cssMin'], 'thumbnail': t['thumbnail']}
for t in watch_themes])
except Exception as e:
print(e)
cache.set(THEME_CACHE_KEY, json.dumps(ex_themes), 24 * 3600)
themes.extend(ex_themes)
nodes.append(loader.render_to_string('xadmin/blocks/comm.top.theme.html', {'themes': themes, 'select_css': select_css}))
