通用圖像識別——百度API調用

基於python 2.7

'''
獲取access_token
'''
import urllib, urllib2, sys
import ssl

# client_id 爲官網獲取的AK， client_secret 爲官網獲取的SK
host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=【官網獲取的AK】&client_secret=【官網獲取的SK】'
request = urllib2.Request(host)
request.add_header('Content-Type', 'application/json; charset=UTF-8')
response = urllib2.urlopen(request)
content = response.read()
if (content):
    print(content)
# 提取其中"access_token":"************",下面會用到
