问题描述

我正在尝试创建使用Google Translate API的Node.js代码. 我从Google Doc( https://cloud.google.com/translate.com/translate.com/docs/translating-text )

但是，当我运行它时，它说"错误:请求缺少有效的API密钥". 我有钥匙，但我不知道如何和何处设置它.

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()

问题描述

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()
