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")相关推荐：《Python视频教程》 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>相关推荐： Flask框架如何使用HTML模板 |
