freezed

对于像我这样忘记了HTML的人,请确定 <input> 在你的 <form> 有一个 name="" 属性!

from flask import Flask, request

app = Flask(__name__)

@app.route('/', methods=['GET', 'POST'])
def index():
    print("Posted data : {}".format(request.form))

    return """
<form method="post">
    <input type="text">
    <input type="text" id="idtxt2">
    <input type="text" name="txt3" id="idtxt3">  
    <input type="submit" Value="Hopla!">
</form>
"""

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