瓶接收没有数据的HTML POST

Question

@app.route('/', methods=['GET', 'POST']) 
def login(): 
    if request.method == 'GET': 
     if 'USER_TOKEN' in session: 
      return make_response(render_template('index.html')) 
     return make_response(render_template('login.html')) 
    if request.method == 'POST': 
     print 'data :', request.form 
     return make_response(render_template('index.html')) 

我HTML是

<form class="form-horizontal" action="/" method="POST"> 
    <div class="control-group"> 
     <label class="control-label" for="email">Email</label> 
     <div class="controls"> 
     <input type="text" id="email" placeholder="Email"> 
     </div> 
    </div> 
    <div class="control-group"> 
     <label class="control-label" for="password">Password</label> 
     <div class="controls"> 
     <input type="password" id="password" placeholder="Password"> 
     </div> 
    </div> 
    <div class="control-group"> 
     <div class="controls"> 
     <button type="submit" class="btn">Sign In</button> 
     </div> 
    </div> 
    </form> 

当我从HTML页面提交的数据，我看到

data : ImmutableMultiDict([]) 

为什么数据丢失？

Answer 1

您缺少字段名称（这是ImmutableMultiDict的密钥，这就是为什么表单提交时它看起来为空）。

变化

<input type="text" id="email" placeholder="Email"> 

到

<input name="<whatever_email_name>" type="text" id="email" placeholder="Email"> 

和

<input type="password" id="password" placeholder="Password"> 

到

<input name="<whatever_password_name>" type="password" id="password" placeholder="Password">
