python api对json对象的响应 [英] python api response to json object
问题描述
我正在尝试编写一个脚本来使用jq解析api响应.我可以使用bash和cli使它正常工作，但是我想用python编写脚本，以便可以在其中添加更多逻辑.我遇到的问题是我可以得到api响应，但是当我尝试使用json.loads()或json.dump()加载它时，我不断收到以下错误:
I am trying to write a script to parse over an api response using jq. I can get it to work using bash and the cli, but i want to script it in python so i can put a lot more logic into it. The problem i am having is that i can get the api response but when i try load it using the json.loads() or json.dump() i keep getting the following error:
TypeError: the JSON object must be str, bytes or bytearray, not APIResponse
这是我从api获得的响应
Here is the response i get from the api
APIResponse({

推荐答案
api返回一个对象，而不是预期的JSON.您也许可以修改您的请求，但是在任何情况下都可以拉出json对象.举例来说，我是针对我点击的股票api执行此操作的.
The api is returning an object, rather than JSON as expected. You might be able to modify your request but in any case you can pull out the json object. By way of example, I do this for a stock api I hit.
a = api.get_asset('NFLX')
这将返回:
Asset({ 'class': 'us_equity',
'easy_to_borrow': True,
'exchange': 'NASDAQ',
'id': 'bb2a26c0-4c77-4801-8afc-82e8142ac7b8',
'marginable': True,
'name': 'Netflix, Inc. Common Stock',
'shortable': True,
'status': 'active',
'symbol': 'NFLX',
'tradable': True})
要检索元素，我使用以下方法:
To retrieve the elements I use the following methods:
getattr(a, 'symbol') or a.symbol
如果您执行dir(a)，则会看到以下内容:
If you do dir(a), you see this:
In [21]: dir(a)
Out[21]:
['__class__',
'__delattr__',
'__dict__',
'__dir__',
'__doc__',
'__eq__',
'__format__',
'__ge__',
'__getattr__',
'__getattribute__',
'__gt__',
'__hash__',
'__init__',
'__init_subclass__',
'__le__',
'__lt__',
'__module__',
'__ne__',
'__new__',
'__reduce__',
'__reduce_ex__',
'__repr__',
'__setattr__',
'__sizeof__',
'__str__',
'__subclasshook__',
'__weakref__',
'_raw']
a._raw输出以下内容:
a._raw outputs this:
In [23]: a._raw
Out[23]:
{'id': 'bb2a26c0-4c77-4801-8afc-82e8142ac7b8',
'class': 'us_equity',
'exchange': 'NASDAQ',
'symbol': 'NFLX',
'name': 'Netflix, Inc. Common Stock',
'status': 'active',
'tradable': True,
'marginable': True,
'shortable': True,
'easy_to_borrow': True}
您可以通过以下方式获取JSON:
You can get the JSON this way:
In [25]: a.__dict__
Out[25]:
{'_raw': {'id': 'bb2a26c0-4c77-4801-8afc-82e8142ac7b8',
'class': 'us_equity',
'exchange': 'NASDAQ',
'symbol': 'NFLX',
'name': 'Netflix, Inc. Common Stock',
'status': 'active',
'tradable': True,
'marginable': True,
'shortable': True,
'easy_to_borrow': True}}
还
In [26]: a.__class__
Out[26]: alpaca_trade_api.entity.Asset
根据您要执行的操作，可以调用以下任何一种方法来获取json并直接使用它.
Depending on what you want to do, you can call any of these methods to get the json and work with it directly.
