如何在 Google Translate Node.js 代码中设置 API KEY [英] How set API KEY in Google Translate Node.js code

问题描述

我正在尝试创建一个使用 google translate api 的 Node.js 代码.我从谷歌文档(https://cloud.google.com/translate/docs/translating-text)

但是当我运行它时，它显示错误:请求缺少有效的 API 密钥."我有钥匙，但我不知道如何以及在哪里设置它.

async function translate() {//导入 Google Cloud 客户端库const { Translate } = require('@google-cloud/translate');//创建一个客户端const translate = new Translate();/*** TODO(开发人员):在运行示例之前取消注释以下行.*/const text = '你好，世界！';const 目标 = 'ru';//将文本翻译成目标语言.文本"可以是一个字符串//翻译一段文本，或用于翻译的字符串数组//多个文本.让 [translations] = await translate.translate(text, target);翻译 = Array.isArray(translations) ?翻译:[翻译]；console.log('翻译:');translations.forEach((translation, i) => {console.log(`${text[i]} => (${target}) ${translation}`);});}翻译()

解决方案

此页面设置身份验证 说明您需要从创建服务帐户密钥页面下载凭据文件.然后可以将其添加到您的路径 (.bashrc) 中，如下所示:

导出 GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

或者，您可以将上面的行添加到项目根目录下的 .env 文件中，并在运行应用程序时获取它:

<预><代码>../.env启动

或

sh -ac '../.env;npm 开始'

I'm trying to create a Node.js code that uses google translate api. I got the code below from the google doc (https://cloud.google.com/translate/docs/translating-text)

But when I run it, it says "Error: The request is missing a valid API key." I have the key, but i don't know how and where to set it.

async function translate() { // Imports the Google Cloud client library
    const { Translate } = require('@google-cloud/translate');

    // Creates a client
    const translate = new Translate();

    /**
     * TODO(developer): Uncomment the following lines before running the sample.
     */
    const text = 'Hello, world!';
    const target = 'ru';

    // Translates the text into the target language. "text" can be a string for
    // translating a single piece of text, or an array of strings for translating
    // multiple texts.
    let [translations] = await translate.translate(text, target);
    translations = Array.isArray(translations) ? translations : [translations];
    console.log('Translations:');
    translations.forEach((translation, i) => {
        console.log(`${text[i]} => (${target}) ${translation}`);
    });
}
translate()

解决方案

This page on setting up authentication explains that you need to download a credentials file from the create service account key page. This can then be added to your path (.bashrc) as follows:

export GOOGLE_APPLICATION_CREDENTIALS="[PATH]"

Alternately, you could add the line above to a .env file on your project root and source it when you are running the application:

. ./.env
npm start

or

sh -ac '. ./.env; npm start'
