我有一个烧瓶应用程序，我想向它添加多种语言。所以我在 Flask_babel 上使用这个演示来做到这一点。 烧瓶标签演示

配置文件

DEBUG = True
LANGUAGES = ['en', 'de', 'fr']

这是app.py

from flask import Flask, request, g
from flask_babel import Babel
from config import Config

# set up application
app = Flask(__name__)
app.config.from_object(Config)

# set up babel
babel = Babel(app)
@babel.localeselector
def get_locale():
    if not g.get('lang_code', None):
        g.lang_code = request.accept_languages.best_match(app.config['LANGUAGES'])
    return g.lang_code

babel.cfg

[python: app/**.py]
[jinja2: **/templates/**.html]
extensions=jinja2.ext.autoescape, jinja2.ext.with_

要开始这个过程，我首先使用了这个命令

pybabel extract -F babel.cfg -o messages.pot .

然后这个

pybabel init -i messages.pot -d app/translations -l de

它生成messages.po文件

我如何翻译每一个msgid。演示说要手动执行此操作，但这是一个演示，它仅包含 10 行，但我的项目将包含 10 种语言的数百个翻译，那么我该怎么做呢？如何通过库或程序将未翻译的 .po 文件转换为已翻译的 .po 文件？

您可以通过 deepl.com 或任何其他翻译 api 设置自己的自动翻译，或者您需要在 po 编辑器的帮助下自己完成所有操作。
