javascript - Node 中的 OpenAI API 给出了基本的 Await 错误。我该如何解决？

Question

我从字面上复制了 openAI 示例中的代码，它给了我一个补救性 Await JS 错误，但我不确定它希望我做什么。我只想启动一个 Express.js 实例并从 openapi(最终是 chatgpt)获得一个 hello world。 Web 服务器工作正常。

这是我的工作:

const express = require('express')
const app = express()


const { Configuration, OpenAIApi } = require("openai");

const configuration = new Configuration({
  apiKey: "my key is here"
});
const openai = new OpenAIApi(configuration);

const completion = await openai.createCompletion({
  model: "text-davinci-002",
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);



app.get('/', function (req, res) {
  res.send('Hello World')
})

app.listen(3000)

错误:

SyntaxError: await is only valid in async functions and the top level bodies of modules

原始的 OpenAI 示例代码是相同的。为什么这是示例代码？

const { Configuration, OpenAIApi } = require("openai");

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

const completion = await openai.createCompletion({
  model: "text-davinci-002",
  prompt: "Hello world",
});
console.log(completion.data.choices[0].text);

Answer 1

如前所述，您需要将异步代码包装在一个函数中:

const express = require('express')
const app = express()
const { Configuration, OpenAIApi } = require("openai");

const configuration = new Configuration({
  apiKey: "my key is here"
});

const openai = new OpenAIApi(configuration);

const completionFunction = async () => {
  const completion = await openai.createCompletion({
    model: "text-davinci-002",
    prompt: "Hello world",
  });
  
  console.log(completion.data.choices[0].text);
};

completionFunction();

app.get('/', function (req, res) {
  res.send('Hello World')
})

app.listen(3000)

此外，请确保您有一个具有适当依赖项的 package.json 文件:

{
  "name": "sample",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.18.2",
    "openai": "^3.1.0"
  }
}
