路由 vs 资源

下面是一个示例代码，展示了如何使用路由和资源的解决方法：

from flask import Flask, jsonify, request

app = Flask(__name__)

# 定义路由和资源
books = [
    {"id": 1, "title": "Book 1"},
    {"id": 2, "title": "Book 2"},
    {"id": 3, "title": "Book 3"}
]

# 使用路由获取所有资源
@app.route('/books', methods=['GET'])
def get_books():
    return jsonify(books)

# 使用路由获取特定资源
@app.route('/books/<int:book_id>', methods=['GET'])
def get_book(book_id):
    for book in books:
        if book['id'] == book_id:
            return jsonify(book)
    return jsonify({"message": "Book not found"}), 404

# 使用路由创建资源
@app.route('/books', methods=['POST'])
def create_book():
    new_book = {"id": len(books) + 1, "title": request.json['title']}
    books.append(new_book)
    return jsonify(new_book), 201

# 使用路由更新资源
@app.route('/books/<int:book_id>', methods=['PUT'])
def update_book(book_id):
    for book in books:
        if book['id'] == book_id:
            book['title'] = request.json['title']
            return jsonify(book)
    return jsonify({"message": "Book not found"}), 404

# 使用路由删除资源
@app.route('/books/<int:book_id>', methods=['DELETE'])
def delete_book(book_id):
    for book in books:
        if book['id'] == book_id:
            books.remove(book)
            return jsonify({"message": "Book deleted"})
    return jsonify({"message": "Book not found"}), 404

if __name__ == '__main__':
    app.run()

这个示例使用Flask框架创建了一个简单的RESTful API，处理了对图书资源的GET、POST、PUT和DELETE请求。使用路由来定义不同的API端点，并使用资源来存储和管理图书数据。
