import requests import base64 import requests import json

def main(): url = "https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=bhNphgcigCgpRKbPDM4tu5nF&client_secret=MlA31Q8jQs65YGAXEnCd2lC2tVnaQhml"

payload = ""
headers = {
    'Content-Type': 'application/json',
    'Accept': 'application/json'
}

response = requests.request("POST", url, headers=headers, data=payload)
return response

if name == 'main': response = main() x = json.loads(response.text) m = x["refresh_token"]

# 二进制方式打开图片文件
f = open('z\\4.img', 'rb')

response = requests.post(request_url, data=params, headers=headers)

print(response.json())  # 将结果打印出
