xadmin下设置“use_bootswatch = True”无效

xadmin采用源代码的方式引入到项目中

在xadmin使用的过程中，设置“use_bootswatch = True”，企图调出主题菜单，显示更多主题。然而设置了后，发现主题还是默认和bootstrap2，深入跟踪源代码，发现/xadmin/plugins/themes.py下的

block_top_navmenu

当use_bootswatch 为True的时候，就会使用httplib2去

http://bootswatch.com/api/3.json

网址获取主题菜单项。但是使用浏览器打开这个网址，http会被替换成https的。httplib2访问这个https的网址，就会报错。报错信息为：

[SSL: SSLV3_ALERT_HANDSHAKE_FAILURE] sslv3 alert handshake failure

这边使用requests库来替代httplib2.

1.安装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 #假如为True使用原来的代码，假如为Flase，使用requests库来访问 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}))
