python - AttributeError ("' str' 对象没有属性 'read'")

Question

在 Python 中出现错误:

Exception:  (<type 'exceptions.AttributeError'>,
AttributeError("'str' object has no attribute 'read'",), <traceback object at 0x1543ab8>)

给定python代码:

def getEntries (self, sub):
    url = 'http://www.reddit.com/'
    if (sub != ''):
        url += 'r/' + sub
    
    request = urllib2.Request (url + 
        '.json', None, {'User-Agent' : 'Reddit desktop client by /user/RobinJ1995/'})
    response = urllib2.urlopen (request)
    jsonStr = response.read()
    
    return json.load(jsonStr)['data']['children']

这个错误是什么意思，我做了什么导致它？

问题在于，对于 json.load，您应该传递一个像对象一样的文件，其中定义了 read 函数。所以要么你使用json.load(response)或 json.loads(response.read()) .
