如何在html flask视图中将字符串转换为整数

from flask import Flask, render_template, request

app = Flask(__name__)

@app.route('/convert', methods=['GET', 'POST'])
def convert():
    if request.method == 'POST':
        # 获取表单参数
        string_param = request.form.get('string_param')
        
        # 将字符串转换为整数
        try:
            integer_param = int(string_param)
        except ValueError:
            return "Invalid input, please enter a valid integer."
        
        # 将整数传递给HTML模板进行渲染
        return render_template('result.html', integer_param=integer_param)
    
    return render_template('form.html')

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