在flask应用程序中提取包含关键字的句子

from flask import Flask, request
import re

app = Flask(__name__)

@app.route('/extract_sentences', methods=['POST'])
def extract_sentences():
    data = request.get_json()  # 获取请求中的JSON数据
    keyword = data['keyword']  # 获取关键字

    text = data['text']  # 获取待处理的文本
    sentences = re.split(r'(?<=[.!?])\s+', text)  # 使用正则表达式分割句子

    keyword_sentences = []  # 存储包含关键字的句子
    for sentence in sentences:
        if keyword.lower() in sentence.lower():  # 判断句子中是否包含关键字（不区分大小写）
            keyword_sentences.append(sentence)

    return {'keyword_sentences': keyword_sentences}

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