我是python的新手,我试图创建一个非常简单的REST服务API调用。我需要这些数据才能将它导入另一个只支持python的应用程序。我的问题是我创建了一个python类并尝试将其导入我的应用程序。我有几个错误,然后修改我的类文件,包括添加一个名为parse_json的新函数。当我运行我的应用程序时,它说该对象没有属性parse_json。当我直接在类中运行代码时它可以工作,但是从一个单独的文件运行并导入该类会给我上面的错误。
../ bin / lib / meetupapi.py - >我的班级文件
class MeetupAPI(object):
BASE_URL = 'https://api.meetup.com'
def __init__(self, request_uri, api_key, group_urlname):
self.request_uri = request_uri
self.api_key = api_key
self.group_urlname = group_urlname
# Parse JSON query from API Call
def parse_json(self, url, result_type=0):
self.url = url
self.result_type = result_type
self.json_obj = urllib2.urlopen(self.url)
self.data = json.load(self.json_obj)
if result_type is not 0:
if self.data[result_type]:
return json.dumps(self.data[result_type])
else:
return json.dumps(self.data)
# Get member IDs for profile
def get_mid(self, request_type):
self.request_type = request_type
if self.request_type == 'member':
self.url = MeetupAPI.BASE_URL + '/2/members?key=' + \
self.api_key + '&group_urlname=' + self.group_urlname
elif self.request_type == 'event':
url = MeetupAPI.BASE_URL + '/2/events?key=' + \
self.api_key + '&group_urlname=' + self.group_urlname
self.json_obj = urllib2.urlopen(self.url)
self.data = json.load(self.json_obj)
self.mids = []
for self.item in self.data['results']:
if self.item['id']:
self.mids.extend([self.item['id']])
return self.mids
# Get Group IDs for reference
def get_gid(self):
self.url = MeetupAPI.BASE_URL + '/' + \
self.group_urlname + '?key=' + self.api_key
return self.url
# Main Meetup API Query for group based information
def query(self):
self.url = MeetupAPI.BASE_URL + self.request_uri + '?key=' + \

# Get member or event profile information
def profile(self,mid,gid):
self.mid = mid
self.gid = gid
self.url = MeetupAPI.BASE_URL + '/2/profile/' + \
str(self.gid) + '/' + \
str(self.mid) + '?key=' + self.api_key
return self.url
../ bin / test.py - >我的测试文件
# Import required libraries
from meetupapi import MeetupAPI
Meetup = MeetupAPI(
'/2/members',
'xxxxxxx',
'xxxxxxx'
)
mids = Meetup.get_mid('member')
group = Meetup.get_gid()
gid = Meetup.parse_json(group, 'id')
for mid in mids:
member = Meetup.profile(mid, gid)
profile = Meetup.parse_json(member)
print profile
运行时出错
Traceback (most recent call last):
File "./test2.py", line 25, in <module>
gid = Meetup.parse_json(group, 'id')
AttributeError: 'MeetupAPI' object has no attribute 'parse_json'
请记住,我以前从未在python中写过一个类,所以我可能错过了一些非常简单的东西。我已经查看了为我能找到的其他人提供的所有答案,但似乎没有任何内容。非常感谢您提供的任何帮助。

检查lib目录中的meetupapi.pyc(注意“c”)并删除它。然后再次尝试导入模块。导入时,模块被编译为字节码。如果你修改了文件,新的编译应该自动完成,但可能没有。
