Flask框架如何使用表单

每个web应用都需要使用表单来采集用户数据。现在让我们使用Flask框架创建一个简单的表单来收集用户的基本信息,例如名称、年龄、邮件、兴趣爱好等,我们将这个模板文件命名为bio_form.html。
<!DOCTYPE html><html><head> <title></title></head><body> <h1>Bio Data Form</h1> <form action="showbio"> <label>Username</label> <input type="name" name="username"><br> <label>Email</label> <input type="email" name="email"><br> <label>Hobbies</label> <input type="name" name="hobbies"><br> <input type="submit" name=""> </form></body></html>
视图函数bio_data_form同时支持POST和GET请求。GET请求将渲染bio_form.html模板,而POST请求将重定向到showbio:
@app.route('/form', methods=['POST', 'GET'])def bio_data_form(): if request.method == "POST": username = request.form['username'] age = request.form['age'] email = request.form['email'] hobbies = request.form['hobbies'] return redirect(url_for('showbio', username=username, age=age, email=email, hobbies=hobbies)) return render_template("bio_form.html")

下面是showbio的实现:
@app.route('/showbio', methods=['GET']) def showbio(): username = request.args.get('username') age = request.args.get('age') email = request.args.get('email') hobbies = request.args.get('hobbies') return render_template("show_bio.html", username=username, age=age, email=email, hobbies=hobbies)
以及show_bio.html的内容:
<!DOCTYPE html><html><head> <title>Bio-Data Details</title></head><body> <h1>Bio-Data Details</h1> <hr> <h1>Username: {{ username }}</h1> <h1>Email: {{ email }}</h1> <h1>Hobbies: {{ hobbies }}</h1></body></html>
