文档都有了
# Here we useimport getpass
import getpass
import os
if "OPENAI_API_KEY" not in os.environ:
os.environ["OPENAI_API_KEY"] = getpass.getpass("OpenAI API Key:")
# copy from tidb cloud console
tidb_connection_string_template = "mysql+pymysql://<USER>:<PASSWORD>@<HOST>:4000/<DB>?ssl_ca=/etc/ssl/cert.pem&ssl_verify_cert=true&ssl_verify_identity=true"
# tidb_connection_string_template = "mysql+pymysql://root:<PASSWORD>@34.212.137.91:4000/test"
tidb_password = getpass.getpass("Input your TiDB password:")
tidb_connection_string = tidb_connection_string_template.replace(
"<PASSWORD>", tidb_password
)
到了8.4版本，tidb_connection_string_template这个配置好估计就可以用了。
