科技部官方网站首页：深入探究ChatGPT编程能力与实践案例

前言

在这个快速变化的数字时代，技术不断进步，我们面临着越来越多的编程挑战。今天，我将带领大家走进ChatGPT这款革命性的工具，它以其强大的编程超能力赢得了广泛关注。通过13个章节和50个实例，我们一起揭开它的神秘面纱，让初学者也能轻松掌握。

一、代码生成

ChatGPT不仅能够生成各种Web开发任务的代码，还能帮助我们提高效率，让工作流程更加顺畅。无论是HTML、CSS还是JavaScript函数，甚至是数据库查询语句，都可以让它帮忙搞定。

1.1 提示词:

Generate a semantic and accessible HTML and (framework) CSS [UI component] consisting of [component parts]. The [component parts] should be [layout].

举例:

Generate a semantic HTML and Tailwind CSS Contact Support form consisting of the users name, email, issue type, and message. The form elements should be stacked vertically and placed inside a card.

联系支持

在这个表单中，姓名和电子邮件是必填字段，因此可以在输入框中使用required属性。您还可以根据需要自定义CSS样式。

1.2 提示词:

Write a JavaScript function. It accepts [input] and returns [output].

举例:

Write a JavaScript function that accepts an array of numbers as input and returns the sum of all numbers in the array.

生成结果：

function sumNumbers(numbers) {

let total = 0;

for (let i = 0; i < numbers.length; i++) {

total += numbers[i];

}

return total;

}

例如，如果输入数组为[10,20,30],则该函数将返回60。

1.3 提示词:

Write an API for fetching data from/ updating data to MongoDB.

举例:

Create an Express.js API to fetch user information from MongoDB.

生成结果：

const express = require('express');

const mongoose = require('mongoose');

const bodyParser = require('body-parser');

// Connect to MongoDB database

mongoose.connect('mongodb://localhost/myapp', { useNewUrlParser: true })

.then(() => console.log('Connected to MongoDB'))

.catch((err) => console.error(Error connecting to MongoDB: ${err}));

// Define User model schema

const userSchema = new mongoose.Schema({

name: String,

email: String,

password: String

});

const User = mongoose.model(User, userSchema);

// Add middleware for parsing JSON requests body-parser.json()

app.use(bodyParser.json());

// Define API route for fetching user information by ID

app.get('/api/user/:id', async (req, res) => {

const userId = req.params.id;

try {

// Fetch user document using Mongoose's findById method with callback or promise-based implementation.

const userDoc = await User.findById(userId);

if (!userDoc || !userDoc._doc.name && !userDoc._doc.email && !userDoc._doc.password)

res.status(404).send({ message: 'User not found.' });

// Send response containing fetched data in JSON format.

res.send(userDoc);

} catch (error) {

// Handle any errors that occur during execution by logging it on server-side logs or sending appropriate error response back to client.

console.error(error.message);

res.status(500).send({ message: 'Internal Server Error.' });

}

});

// Start server listening on port number provided as command-line argument or default value when no argument is given.
