在Debian上使用Swagger进行API文档国际化,可以按照以下步骤进行:
首先,确保你的Debian系统已经安装了Swagger和相关的工具。你可以使用以下命令来安装Swagger:
sudo apt update
sudo apt install swagger-ui-express
创建一个Swagger配置文件(通常是swagger.json),并定义你的API文档。为了支持国际化,你需要在配置文件中添加多语言支持。
{
"swagger": "2.0",
"info": {
"title": "My API",
"description": "API documentation with internationalization",
"version": "1.0.0"
},
"host": "api.example.com",
"basePath": "/v1",
"schemes": [
"https"
],
"paths": {
"/items": {
"get": {
"summary": "Get items",
"description": "This endpoint returns a list of items",
"responses": {
"200": {
"description": "A JSON array of items",
"schema": {
"type": "array",
"items": {
"$ref": "#/definitions/Item"
}
}
}
}
}
}
},
"definitions": {
"Item": {
"type": "object",
"properties": {
"id": {
"type": "integer"
},
"name": {
"type": "string"
}
}
}
},
"tags": [
{
"name": "items",
"description": "Operations pertaining to items"
}
],
"externalDocs": {
"description": "Find more info here",
"url": "https://swagger.io/tools/swagger-ui/"
}
}
为了支持多语言,你可以在Swagger配置文件中使用description字段来提供不同语言的描述。例如:
{
"paths": {
"/items": {
"get": {
"summary": "Get items",
"description": {
"en": "This endpoint returns a list of items",
"zh": "此端点返回项目列表"
},
"responses": {
"200": {
"description": {
"en": "A JSON array of items",
"zh": "一个项目的JSON数组"
},
"schema": {
"type": "array",
"items": {
"$ref": "#/definitions/Item"
}
}
}
}
}
}
}
}
使用Swagger UI Express来展示你的API文档,并支持多语言。你可以使用以下命令来启动Swagger UI Express:
npx swagger-ui-express --swagger-file ./swagger.json --port 3000
Swagger UI Express本身不直接支持多语言,但你可以使用第三方库(如i18next)来实现多语言支持。首先,安装i18next和i18next-http-middleware:
npm install i18next i18next-http-middleware
然后,在你的Express应用中配置i18next:
const express = require('express');
const swaggerUi = require('swagger-ui-express');
const i18n = require('i18next');
const Backend = require('i18next-fs-backend');
i18n.use(Backend).init({
fallbackLng: 'en',
debug: true,
interpolation: {
escapeValue: false
}
}, (err, t) => {
if (err) return console.error(err);
const app = express();
app.use('/api-docs', swaggerUi.serve, swaggerUi.setup({
swaggerOptions: { url: '/swagger.json' }
}));
app.listen(3000, () => {
console.log('Server is running on port 3000');
});
});
更新你的Swagger配置文件,将多语言描述放在单独的文件中,并在Swagger配置文件中引用这些文件。例如:
{
"swagger": "2.0",
"info": {
"title": "My API",
"description": "API documentation with internationalization",
"version": "1.0.0"
},
"host": "api.example.com",
"basePath": "/v1",
"schemes": [
"https"
],
"paths": {
"/items": {
"get": {
"summary": "Get items",
"description": {
"en": "This endpoint returns a list of items",
"zh": "此端点返回项目列表"
},
"responses": {
"200": {
"description": {
"en": "A JSON array of items",
"zh": "一个项目的JSON数组"
},
"schema": {
"type": "array",
"items": {
"$ref": "#/definitions/Item"
}
}
}
}
}
}
},
"definitions": {
"Item": {
"type": "object",
"properties": {
"id": {
"type": "integer"
},
"name": {
"type": "string"
}
}
}
},
"tags": [
{
"name": "items",
"description": "Operations pertaining to items"
}
],
"externalDocs": {
"description": "Find more info here",
"url": "https://swagger.io/tools/swagger-ui/"
}
}
通过以上步骤,你可以在Debian上使用Swagger进行API文档国际化。
