您好我想配置我的MIME类型:配置MIME类型
的MIME类型的KML文件是
* application/vnd.google-earth.kml+xml
我怎样才能做到这一点与谷歌应用程序引擎?我生成一个模板,看起来像这样的KML:更新我尝试设置MIME类型如下面的代码
<?xml version="1.0" encoding="UTF-8"?><kml xmlns="http://www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http://www.w3.org/2005/Atom">
<Document>{% for article in articles %}{% if article.geopt %}
<Placemark><name></name>
<description>
<![CDATA[{% if article.kmluri2view %}<img src="http://{{host}}/images/{{ article.kmluri2view.key.id }}.jpg">{% endif %}<a href="http://{{host}}/{{article.key.id}}"> {{ article.title }} </a><br/>{{article.text}}]]></description><Point><coordinates>{{article.geopt.lon|floatformat:2}},{{article.geopt.lat|floatformat:2}}</coordinates></Point>
</Placemark>{% endif %}{% endfor %}
</Document>
</kml>
。我如何验证它的工作原理?
class KMLHandler(webapp.RequestHandler):
def get(self):
start=datetime.datetime.now()-timedelta(days=10)#vary
host = os.environ.get("HTTP_HOST", os.environ["SERVER_NAME"])
logging.debug('host '+host)
count = int(self.request.get('count')) if not self.request.get('count')=='' else 1000
from google.appengine.api import memcache
memcache.flush_all()
memcache_key = "ads"
data = memcache.get(memcache_key)
if data is None:
a= Ad.all().filter("modified >", start).filter("url IN", ['www.koolbusiness.com']).filter("published =", True).order("-modified").fetch(count)
memcache.set("ads", a)
else:
a = data
dispatch='templates/kml.html'
template_values = {'a': a , 'request':self.request, 'host':host}
path = os.path.join(os.path.dirname(__file__), dispatch)
self.response.headers['Content-Type'] = 'application/vnd.google-earth.kml+xml'
self.response.out.write(template.render(path, template_values))
您正在使用哪种框架? – systempuntoout 2011-04-06 18:37:07
我用纯webapp运行它只是分配一个实体列表到模板。如果你建议一个框架,你是最欢迎这样做的。 – 2011-04-09 15:46:04
