按照这个操作进行创建一个应用：
代码示例
token获取
# 填充API Key与Secret Key
import requests
import json
def main():
url = "https://aip.baidubce.com/oauth/2.0/token?client_id=【API Key】&client_secret=【Secret Key】&grant_type=client_credentials"
payload = json.dumps("")
headers = {
'Content-Type': 'application/json',
'Accept': 'application/json'
}
response = requests.request("POST", url, headers=headers, data=payload)
return response.json().get("access_token")
if __name__ == '__main__':
access_token = main()
print(access_token)
