尝试转储JSON时出错[关闭]

Question

我在Python之前没有经验，除了近10年前我做过的一些乱七八糟的事情。我试图从OMDB API读取数据并在Python 2.7.14中不断收到错误。

这是应该返回的示例：

> {"Title":"The Matrix","Year":"1999","Rated":"R","Released":"31 Mar
> 1999","Runtime":"136 min","Genre":"Action, Sci-Fi","Director":"Lana
> Wachowski, Lilly Wachowski","Writer":"Lilly Wachowski, Lana
> Wachowski","Actors":"Keanu Reeves, Laurence Fishburne, Carrie-Anne
> Moss, Hugo Weaving","Plot":"A computer hacker learns from mysterious
> rebels about the true nature of his reality and his role in the war

> controllers.","Language":"English","Country":"USA","Awards":"Won 4

> Sep 1999","BoxOffice":"N/A","Production":"Warner Bros.
> Pictures","Website":"http://www.whatisthematrix.com","Response":"True"}

到目前为止，这是我的Python代码：

import requests
API_KEY = '******'
Movie = 'The Matrix'
results = requests.get("http://www.omdbapi.com/", 
              params={'apikey': API_KEY, 't': Movie})

我得到了一个结果。

在这个阶段之后导入json后我尝试运行json.dumps（结果），这给了我错误：

Traceback (most recent call last):
  File "<pyshell#12>", line 1, in <module>
    json.dumps(results)
  File "C:\Python27\lib\json\__init__.py", line 244, in dumps
    return _default_encoder.encode(obj)
  File "C:\Python27\lib\json\encoder.py", line 207, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "C:\Python27\lib\json\encoder.py", line 270, in iterencode
    return _iterencode(o, 0)
  File "C:\Python27\lib\json\encoder.py", line 184, in default
    raise TypeError(repr(o) + " is not JSON serializable")
TypeError: <Response [200]> is not JSON serializable

我在这里错过了什么？

Answer 1

results不是str，它是requests.models.Response对象。尝试调用它的.json()方法，如下所示：

import requests
API_KEY = '******'
Movie = 'The Matrix'
results = requests.get("http://httpbin.org/get", 
              params={'apikey': API_KEY, 't': Movie})

data = results.json()

print data
