最近在整理草稿箱。2022-07-25。我的token应该早过期了哈，需要大家去官网查看最新的api接口+申请替换钥匙喔。
介绍
图像清晰度增强官网介绍&预览
API文档
API调用方式
ApiExplorer平台
实践
Python 解释器
1.交互命令
print('当前 Python 解释器目录：')
print(os.path.dirname(sys.executable))r"""
当前 Python 解释器目录：
C:\Users\jpch89\AppData\Local\Programs\Python\Python36
"""2. 直接在控制台查看
Windows 版：cmd下，使用 where python
获取token
# encoding:utf-8
import requests # client_id 为官网获取的AK， client_secret 为官网获取的SK
host = 'https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=【。。】&client_secret=【。。】'
response = requests.get(host)
if response:print(response.json())响应：
{'refresh_token': '！！',
'expires_in': 2592000, 'session_key': '','access_token': '！！','scope': ''}
调用
# encoding:utf-8import requests
import base64'''
图像清晰度增强
'''request_url = "https://aip.baidubce.com/rest/2.0/image-process/v1/image_definition_enhance"
# 二进制方式打开图片文件
f = open('[本地文件]', 'rb')
img = base64.b64encode(f.read())params = {"image":img}
access_token = '[调用鉴权接口获取的token]'
request_url = request_url + "?access_token=" + access_token
headers = {'content-type': 'application/x-www-form-urlencoded'}
response = requests.post(request_url, data=params, headers=headers)
if response:print (response.json())
参考菜品识别项目
