私はpythonの新しい人です。今日、検索関数を書いているときにエラーが発生しました。まあ、それを行うためにsqlalchemy ormを使用しています。関数で、キーワードとして中国語を入力します.htmlページはUnicodeEncodeErrorを返しますat /user/search:'latin-1' コーデックは位置 0-1 の文字をエンコードできません: 序数が範囲内にありません (256)。私のコードは次のようなものです：
def user_search(request):
name = request.GET.get('name').strip()
user_list = list()
if name:
user_list = User.get_by_name(name)
class User(object):
@classmethod
def get_by_name(cls, name):
return DBSession.query(cls).filter(cls.name==name)
トレースバックは次のとおりです。

エラーに遭遇したとき、Pythonシェルでテストを行いました。うまく機能しました。コードは次のとおりです。
from apps.user.models import User user = User.get_by_name('某人').first() print user print user.name 某人
私のhtmlページでそれを機能させるにはどうすればよいですか？
