UnicodeDecodeError：“utf-8”编解码器无法解码位置 61 中的字节 0xd4：无效的连续字节

Question

为什么我会遇到这样的问题？你是怎么解决的？我正在尝试连接到 postgresql

import psycopg2

conn = psycopg2.connect(database="test", user="postgres", password="260508", host="localhost", port="5432")
print("Database Connected....")

结果我有错误。

Traceback (most recent call last):
  File "C:\Users\gamer\Desktop\PyCharm Workspace\PyCharm Workspace\SQL Test\SQL Test\main.py", line 3, in <module>
    conn = psycopg2.connect(database="test", user="postgres", password="260508", host="localhost", port="5432")
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\gamer\Desktop\PyCharm Workspace\PyCharm Workspace\SQL Test\SQL Test\.venv\Lib\site-packages\psycopg2\__init__.py", line 122, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd4 in position 61: invalid continuation byte

我试图像那样解码和编码

import psycopg2
import base64

password = "260508".encode('utf-8')  # Encode directly to UTF-8
encoded_password = base64.b64encode(password).decode('utf-8') 

conn = psycopg2.connect(database="test", user="postgres", password=encoded_password, host="localhost", port="5432")
print("Database Connected....")

Answer 1

您使用的编码方法是否正确您可以通过运行来检查：

print(conn.encoding)

，如果需要，可以通过

conn.set_client_encoding('UNICODE')

或

conn.set_client_encoding('UTF8')

设置正确的编码
