Got an error when I tried to use the Openai SDK in Node.js

题意：尝试在Node.js中使用OpenAI SDK时遇到错误

问题背景：

I am trying to use Openai api with nodejs, I follow the tutorial and want to add a simple gpt text completion feauture using the openai SDK, but I got an error says: /node_modules/openai/core.js:44 const isJSON = contentType?.includes('application/json') || contentType?.includes('application/vnd.api+json');

尝试在 Node.js 中使用 OpenAI API，并遵循了相关教程，希望使用 OpenAI SDK 添加一个简单的 GPT 文本补全功能。但是，我遇到了一个错误，该错误指向 node_modules/openai/core.js 文件的第 44 行，其中使用了可选链操作符（?.），但 Node.js 环境似乎不支持它

It results in a crash of the app, I didn't find out why.

这导致应用程序崩溃，我没有找出原因。

This is the code:        这是代码：

import OpenAI from 'openai';

const openai = new OpenAI({
    apiKey: process.env.OPENAI_API_KEY,
});

export const gptResponse = async (req, res) => {
    try {
        const { message } = req.body;
        const getResponse = await openai.chat.completions.create({
            model: 'gpt-3.5-turbo',
            messages: [
                {
                    role: 'system',
                    content: 'You are a helpful assistant.',
                },
                {
                    role: 'user',
                    content: message,
                },
            ],
        });
        console.log(getResponse.data.choices[0].message.content);
        return res.json(getResponse.data.choices[0].message.content);
    } catch (err) {
        console.log(err);
        return res.status(400).send('Error. Try again.');
    }
};

问题解决：

This code will work.        代码正常运行

Save as `demo.js'        另存为文件 demo.js

import OpenAI from 'openai';

const openai = new OpenAI({
    apiKey: process.env.OPENAI_API_KEY,
});

const requestData = {
    model: 'gpt-3.5-turbo',
    messages: [
        {
            role: 'system',
            content: 'You are a helpful assistant.',
        },
        {
            role: 'user',
            content: 'Hello!',
        },
    ],
};

async function getGPTResponse() {
    try {
        const response = await openai.chat.completions.create(requestData);
        console.log("Response from OpenAI:", response.choices[0].message.content);
    } catch (error) {
        console.error("Error:", error.message);
    }
}

getGPTResponse();

In package.json

{
  "type": "module",
  "dependencies": {
    "openai": "^4.28.0"
  }
}

Install dependencies        安装依赖

npm install

Run it        运行
