我有一个reactJs应用程序，我想为其添加本地化。我以前从未使用过i18next，但我正在努力适应它。我的问题是，我无法检测到用户浏览器的使用语言。这是我的代码，能否请您提供一些代码，我已经搜索了该主题的所有文档和答案，但找不到任何解决方案。
这是我的i18n.js文件，正在将其导入我要使用的文件中
<div>在这些文件中，我这样使用
import i18next from 'i18next';
import languageDetector from 'i18next-browser-languagedetector';
i18next
.use(languageDetector)
.init({

export default i18next;
这在网页上显示“问题”，但如果我将Google chrome浏览器更改为土耳其语，则仍为英语。我不知道我在想什么。
感谢您的帮助

游戏进行得有点晚了，但希望能使社区受益。我最近开始与react-i18next合作，也遇到了这个问题。我发现此post的子链接指向源代码中的这一行：
https://github.com/i18next/i18next/blob/ee3afd8e5d958e8d703a208194e59fa5228165fd/src/i18next.js#L189
if (!lng && this.services.languageDetector) lng = this.services.languageDetector.detect();
这表明，如果不带任何参数调用changeLanguage()，它将尝试根据您配置的优先级进行语言检测。因此，要使其正常工作，请执行以下操作：
i18n
.use(LanguageDetector)
.use(initReactI18next) // passes i18n down to react-i18next
.init({
resources,
lng: "en",
detection: detectOptions,
interpolation: {
escapeValue: false // react already safes from xss
}
});
//*** call without param to use language detector
i18n.changeLanguage()
完成此操作后，URL查询参数现在可以使用，例如：
www.example.com/route/?lng=tr

希望这对以后的人有所帮助。我在上面尝试了@Ergin的答案，但是没有用，当我使用此建议时，Typescript在传递0 params时引发错误：
//*** call without param to use language detector
i18n.changeLanguage()
文档并没有完全为您提供有关如何设置检测的全部信息，然后我发现一个closed Github issue，那里有几个人在问一个合理的问题，维护人员的回答有些粗鲁，但是还碰巧提供了本应包含在文档中的link。通过对当前文档的说明进行一些细微调整，它解决了我的问题。
然后，我可以使用https:www.domain.com?lng=es在我的网址中进行语言检测，并且可以使用浏览器扩展程序来更改浏览器语言。
这里有我的i18n.ts工作文件：
import i18n from 'i18next'
import LanguageDetector from 'i18next-browser-languagedetector'
import { initReactI18next } from 'react-i18next'
import XHR from "i18next-http-backend" // <---- add this
import commonDe from './locales/de/common.json'
import commonEn from './locales/en/common.json'
import commonEs from './locales/es/common.json'
import commonFr from './locales/fr/common.json'
const resources = {
de: { common: commonDe },
en: { common: commonEn },
es: { common: commonEs },
fr: { common: commonFr }
}
const options = {
order: ['querystring', 'navigator'],
lookupQuerystring: 'lng'
}
i18n
.use(XHR) // <---- add this
.use(LanguageDetector)
.use(initReactI18next)
.init({
// lng: 'en' // <--- turn off for detection to work
detection: options,
resources,
ns: ['common'],
defaultNS: 'common',
fallbackLng: 'en',
supportedLngs: ['de', 'en', 'es', 'fr'],
interpolation: {
escapeValue: false,
},
debug: false,
})
export default i18n
（额外的帮助-如果有人在此部分卡住）
我正在一个Next.js项目中，并且上面的文件像这样被加载到project-root/pages/_app.tsx文件中：
import React from 'react'
import { AppProps } from 'next/app'
import '../i18n/i18n'
import '../public/styles.css'
const TacoFridayApp = ({ Component, pageProps}: AppProps): JSX.Element => {
return <Component {...pageProps} />
}
export default TacoFridayApp
