@route('/locations',method='GET')
def get_location():
entity = db['locations'].find({'coordinate2d': {'$near': [37.871593,-122.272747]}}).limit(3)
if not entity:
abort(404,'No nearby locations')
return entity
上述代码部分的响应是：
Error 500: Internal Server Error
Sorry,the requested URL 'http://localhost:8080/locations' caused an error:
Unsupported response type: 我如何从mongo中获取该信息,因为瓶子可以作为JSON返回？
最佳答案
完整的解决方案是将db游标转换为列表,手动设置响应类型自定义编码返回值的组合
原文链接：https://www.f2er.com/python/439254.html@route('/locations/:lat/:lng',method='GET')
def get_location(lat,lng):
response.content_type = 'application/json'
objdb = db.locations.find({'coordinate2d': {'$near': [lat,lng]}},{'coordinate2d':bool(1)}).skip(0).limit(3)
entries = [entry for entry in objdb]
return MongoEncoder().encode(entries)
在我的情况下,产生这个：
[
