如何在Puppeteer中指定浏览器语言 [英] How to specify browser language in Puppeteer

问题描述

我想使用Puppeteer推出一款语言西班牙语 es 的Google Chrome浏览器。

I would like to launch a Google Chrome browser with language Spanish es using Puppeteer.

我是试过 puppeteer.launch（args：[' - lang = es'，...]，...）但它没有用。

我试过传递环境变量 LANGUAGE = es mocha puppeteer-test.js 但它没有用。

I've tried passing the environment variable LANGUAGE=es mocha puppeteer-test.js but it didn't work.

我尝试使用 userDataDir 选项并传递一个带有偏好设置的文件夹提交 {intl：{accept_languages：es}} 但浏览器设置 - 语言仍然不显示西班牙语，也不显示 window.navigator.languages 既不 window.navigator.language

I've tried using the userDataDir option and passing a folder with a Preferences file a { "intl": { "accept_languages": "es" } } but the browser Settings - Languages still don't show Spanish and neither does window.navigator.languages neither window.navigator.language

Puppeteer 0.11.0

节点8.4.0

NPM 5.2.0

macOS El Capitan 10.11.6

MacBook Pro Retina，15英寸，2015年中期

推荐答案

有几种方法可以更改区域设置，您可以尝试所有o如果他们找到适合你的东西，

There are several ways to change locale, you can try all of them to find what works for you,

const browser = await puppeteer.launch({
    headless: false,
    args: ['--lang=bn-BD,bn']
});

将语言作为标题发送

Send the language as Header

await page.setExtraHTTPHeaders({
    'Accept-Language': 'bn'
});

强行设置语言

Forcefully set the language

// Set the language forcefully on javascript
await page.evaluateOnNewDocument(() => {
    Object.defineProperty(navigator, "language", {
        get: function() {
            return ["bn-BD"];
        }
    });
    Object.defineProperty(navigator, "languages", {
        get: function() {
            return ["bn-BD", "bn"];
        }
    });
});

为了测试，我将用多种语言测试，包括 es ，结果如下。

For the sake of testing, I'll test this in multiple languages, including es, and here is the result.
