Python 瓶子 + postgresql

Question

我有问题。我安装了 pgadmin3。创建了一个编码为 UTF-8 的库。创建文件 index.py:

# -*- coding utf-8 -*-

from bottle import route, run, template, request, install
from bottle_pgsql import PgSQLPlugin

install(PgSQLPlugin('dbname=test, user=postgres password=111'))

@route('/hello')
def hello(db):
    c = db.execute('''SELECT gorod FROM gorod''')
    result = c.fetchone()
    return template('hello', rows=result)

run (host='localhost', port=8080, debug=True)

接下来我创建了 tpl 文件 hello.tpl:

<!DOCTYPE HTML>
<html>
    <head>
        <meta charset="utf-8">
        <title>Статистика</title>
    </head>
    <body>
        <h1>{{rows}}</h1>
    </body>
</html>

当我转到页面 http://localhost:8080/hello error:

Critical error while processing request: /hello

Error:

UnicodeDecodeError('utf8', 'Traceback (most recent call last):\n  File "C:\Users\User\Desktop\test\bottle.py", line 862, in _handle\n    return route.call(**args)\n  File "C:\Users\User\Desktop\test\bottle.py", line 1732, in wrapper\n    rv = callback(*a, **ka)\n  File "C:\Users\User\Desktop\test\bottle_pgsql.py", line 83, in wrapper\n    con = psycopg2.connect(dsn)\n  File "C:\Python27\lib\site-packages\psycopg2\__init__.py", line 164, in connect\n    conn = _connect(dsn, connection_factory=connection_factory, async=async)\nOperationalError: \xc2\xc0\xc6\xcd\xce:  \xe1\xe0\xe7\xe0 \xe4\xe0\xed\xed\xfb\xf5 "test," \xed\xe5 \xf1\xf3\xf9\xe5\xf1\xf2\xe2\xf3\xe5\xf2\n\n', 512, 513, 'invalid continuation byte')

你能帮帮我吗！对不起，我的英语不好 ;）谢谢

您是否尝试过使用 UTF-8 对您的模板文件进行编码？

以 iconv 为例：

iconv -f ascii -t utf-8 "hello.tpl" -o "hello.tpl"

编辑：您可以使用iconv for windows here
