[英]Python API conversion from Python2.7 code to Python3
我正在尝试将这部分转换为 Python3,但无法使其正常工作。
import urllib
import datetime
import urllib2
import httplib
import hmac
from hashlib import sha256
TIMEOUT=60
def getDimMetrics(options):
now = datetime.datetime.now()
# create a dictionary of the arguments to the API call
post_dict = {}
if options.group:
post_dict['group'] = options.group
# start and end are dates, the format will be specified on the command line
# we will simply pass those along in the API
if options.start:
post_dict['start'] = options.start
if options.end:
post_dict['end'] = options.end
# encode the data
post_data = urllib.urlencode(post_dict)
protocol = 'https'
if 'localhost' in options.host:
# for testing
protocol = 'http'
url = protocol + '://' + options.host + options.url + '.' + options.type.lower()
# create the request
request = urllib2.Request(url, post_data)
# add a date header (optional)
request.add_header('Date', str(now))
# calculate the authorization header and add it
hashString = 'POST' + request.get_selector() + request.get_header('Date') + 'application/x-www-form-urlencoded' + str(len(request.get_data()))
calc_sig = hmac.new(str(options.secret), hashString,
sha256).hexdigest()
request.add_header('Authorization', 'Dimo %s:%s' %(options.key, calc_sig))
print 'url=', url
print 'post_data=', post_data
print 'headers=', request.headers
这就是我在 Python3 中所拥有的。 当我运行它时,我收到一条错误消息,指出 400 Malformed Authorization 标头。 如何修复此错误,以便我可以在 python 3 中运行这部分。
from requests_oauthlib import OAuth1Session
CONSUMER_KEY = "aaaaaaaaaaaaaaaaa"
CONSUMER_SECRET = "bbbbbbbbbbbbbbbbbbbb"
host = "api.dimo.com"
uri = "/api/Visits.json"
oauthRequest = OAuth1Session(CONSUMER_KEY,
client_secret=CONSUMER_SECRET)
url = 'https://' + host + uri
headers = {
'Accept': "application/json",
'Accept-Encoding': "application/x-www-form-urlencoded",
'Authorization': "dimo bbbbbbbbbbbbbbb"
}
response = oauthRequest.post(url, headers=headers)
print(response.status_code)
print(response.content)
错误400 b'格式错误的授权标头。\\n'
运行 python 2to3转换器,并根据PEP 8 - Python 样式指南( 最大行长度等)进行一些额外的清理。
