How to use WebMan technology to implement multi-language websites

With the development of the Internet, more and more companies and individuals choose to internationalize their websites in order to Meet the needs of users in different countries and regions. As an important means to achieve internationalization, multilingual websites have been widely used.

In modern network development, using WebMan technology (also known as Web framework) can greatly simplify the website development process and improve development efficiency. This article will introduce how to use WebMan technology to implement a multi-language website and provide relevant code examples.

1. Preparation
Before we start, we need to prepare some basic work.

1. Install WebMan Framework
   First, we need to select and install a suitable WebMan framework. Common WebMan frameworks include Django, Ruby on Rails, ASP.NET MVC, etc. Here we take Django as an example to explain.
2. Install multi-language support
   After installing the WebMan framework, we also need to install the corresponding multi-language support. In Django, we can use the Django Internationalization and Django Localization modules to achieve multi-language support.
3. Prepare translated text
   In order to implement a multi-language website, we need to prepare multiple translated texts in different languages. These texts will be used to replace static text in the website to achieve multi-language display effects.

2. Configure multi-language support
After the preparation work is completed, we need to configure the WebMan framework accordingly to support multi-language functionality.

1. In Django, we need to configure it in the settings.py file. It can be configured as follows:

LANGUAGE_CODE = 'en-us'

LANGUAGES = [
    ('en', 'English'),
    ('zh-cn', '简体中文'),
    ('ja', '日本語'),
]

USE_I18N = True

LOCALE_PATHS = [
    os.path.join(BASE_DIR, 'locale'),
]

where LANGUAGE_CODE is the default language and LANGUAGES is the list of supported languages. USE_I18N configured as True indicates that the internationalization function is enabled. LOCALE_PATHS specifies the path to the multi-language translation file.

2. Create a folder named locale in the project root directory, and create a folder for the corresponding language in it. For example, for Simplified Chinese, we can create a folder named zh_CN under the locale folder.
3. Create a file named django.po in each language folder and use the appropriate tool to translate it. In Django, we can use the gettext tool for translation. You can follow the following example:

$ django-admin makemessages -l zh_CN
$ msginit -i locale/zh_CN/django.po -o locale/zh_CN/LC_MESSAGES/django.mo
$ vim locale/zh_CN/django.po

In the django.po file, we can use msgid and msgstr to translate the text. For example:

msgid "Hello"
msgstr "你好"

3. Use multi-language in the website
After the configuration is completed, we can use the multi-language function in the website. Below are some sample codes for implementing multilingual websites using WebMan technology.

1. Using multiple languages ​​in templates
   In Django, we can use the {% trans %} tag to translate text. For example:

{% load i18n %}
<h1 id="trans-Hello">{% trans "Hello" %}</h1>

2. Using multiple languages ​​in views
   In Django, we can use the ugettext function to get the translated text. For example:

from django.utils.translation import ugettext as _

def hello(request):
    message = _("Hello")
    return HttpResponse(message)

4. Generate translation files
During the website development process, we may need to add or modify translation text. In order for these changes to take effect, we need to regenerate the translation files.

In Django, we can use the following command to generate a translation file:

$ django-admin makemessages -l zh_CN

This will automatically generate the corresponding translation file based on the source code in the project.

Summary:
By configuring and using WebMan technology, we can easily implement multi-language websites. In this article, we introduce the basic steps to implement a multilingual website using the Django framework and provide corresponding code examples. Hope this helps you when developing multilingual websites.
