Question

我已使用flask启动了python个应用。我使用yelp-python https://github.com/Yelp/yelp-python访问yelp api

from yelp.client import Client
from yelp.oauth1_authenticator import Oauth1Authenticator
from IPython import embed

auth = Oauth1Authenticator(
  consumer_key='key',
  consumer_secret='secret',
  token='token',
  token_secret='secret'
)

client = Client(auth)

app = Flask(__name__)

@app.route('/hello')
def hello_world():
  response = client.search('pizza hut')
  embed()
  return jsonify(response)

if __name__ == '__main__':
  app.run(debug=True,host='0.0.0.0')

响应为<yelp.obj.search_response.SearchResponse object at 0x7fab7fc80c50>，jsonify表示无法对其进行序列化。

如何序列化它以便我可以发回json？

我可以解析response.businesses给我一个list，但即使jsonify似乎也不接受。

以下是一些手动解析的示例：

In [1]: response
Out[1]: <yelp.obj.search_response.SearchResponse at 0x7faa0806d940>

In [2]: response.businesses
Out[2]: 
[<yelp.obj.business.Business at 0x7faa0809a1d0>,
 <yelp.obj.business.Business at 0x7faa0809a208>,
 <yelp.obj.business.Business at 0x7faa0809a278>,
 <yelp.obj.business.Business at 0x7faa0809a320>,
 <yelp.obj.business.Business at 0x7faa0809a3c8>,
 <yelp.obj.business.Business at 0x7faa0809a470>,
 <yelp.obj.business.Business at 0x7faa0809a518>,
 <yelp.obj.business.Business at 0x7faa0809a5c0>,
 <yelp.obj.business.Business at 0x7faa0809a668>,
 <yelp.obj.business.Business at 0x7faa0809a710>,
 <yelp.obj.business.Business at 0x7faa0809a7b8>,
 <yelp.obj.business.Business at 0x7faa0809a860>,
 <yelp.obj.business.Business at 0x7faa0809a908>,
 <yelp.obj.business.Business at 0x7faa0809a9b0>,
 <yelp.obj.business.Business at 0x7faa0809aa58>,
 <yelp.obj.business.Business at 0x7faa0809ab00>,
 <yelp.obj.business.Business at 0x7faa0809aba8>,
 <yelp.obj.business.Business at 0x7faa0809ac50>,
 <yelp.obj.business.Business at 0x7faa0809acf8>,
 <yelp.obj.business.Business at 0x7faa0809ada0>]

In [3]: response.businesses[0]
Out[3]: <yelp.obj.business.Business at 0x7faa0809a1d0>

In [4]: response.businesses[0].name
Out[4]: 'Franco Manca'

我想我可以手动设置list dictionaries。我想如果我可以解析＆lt;对象在＆gt;进入一个json对象。如果有人能解释< object at >以及如何处理它，我会很感激。感谢

我很确定“at”之后的所有内容都是记忆中的位置。

那就是说，它只意味着你有一个python对象。您可以使用dir检查python对象上的可用属性，以查看它具有的属性。但是，以下应该主要做你想要的事情：

map(lambda x : x.__dict__, response.businesses)

Python是什么意思＆lt;对象在0x7fab7fc80c50＆gt;我该如何解析呢？
