Question

我正在使用flask做一个Web应用程序，有一点是一种获取值的形式，如下所示：

Pattern.html

{% extends "base.html" %}
{% block body %}

<form action="/patterns" method="post"  enctype="multipart/form-data" >
   <div class="form-group">
     <label for="pattern_name">Nome do padrão</label>
     <input class="form-control" id="pattern_name_input" name="pattern_name_input"  aria-describedby="pattern_name_help" placeholder="Nome do Padrão" required="required" >
     <small id="pattern_name_help" class="form-text text-muted">Nome do padrão. Este valor será usado como entrada no dataframe.</small>
   </div>
   <div class="form-group">
      <label for="pattern_head">Inicio do Padrão</label>
      <input class="form-control" id="pattern_head_input" name="pattern_head_input" aria-describedby="pattern_head_help" placeholder="Início do padrão" >
      <small id="pattern_head_help" class="form-text text-muted">Início do padrão. O padrão será composto por inicio+meio+fim.</small>
    </div>
    <div class="form-group">
      <label for="pattern_middle">Meio do Padrão</label>
      <input class="form-control" id="pattern_middle_input" name="pattern_middle_input" aria-describedby="pattern_middle_help" placeholder="Meio do Padrão" >
      <small id="pattern_middle_help" class="form-text text-muted">Meio do padrão. O padrão será composto por inicio+meio+fim.</small>
    </div>
    <div class="form-group">
      <label for="pattern_tail">Fim do Padrão</label>
      <input class="form-control" id="pattern_tail_input" name="pattern_tail_input" aria-describedby="pattern_tail_help" placeholder="Fim do Padrão" >
      <small id="pattern_tail_help" class="form-text text-muted">Fim do padrão. O padrão será composto por inicio+meio+fim.</small>
    </div>
   <button type="submit" class="btn btn-primary">Adicionar</button>
 </form>
{% endblock %}

在后端，我遵循：

app.py

@app.route('/patterns',methods = ['POST', 'GET'])
def default_patterns():

    if request.method == 'POST':
        default_value = ''
        pattern_name = request.values.get('pattern_name_input', default_value)
        pattern_head = request.values.get('pattern_head_input', default_value)
        pattern_middle = request.values.get('pattern_middle_input', default_value)
        pattern_tail = request.values.get('pattern_tail_input', default_value)

        P_Find.set_new_pattern(pattern_name, pattern_head, pattern_middle, pattern_tail)
        default_params  = P_Find.get_default_params()
        flash("Novo padrão adicionado","info")
        return render_template('default_patterns.html', zippado=default_params)

我以这种方式获得了正确的值，但是问题是当我在表单的内容中放入space字符时，我只收到space之前的文本的第一部分。如何以正确的方式获取文本？

问题在于呈现此值的方式，以前我有过：

   {% for n, h, m, t in zippado %}
      <fieldset>
         <legend>{{ n }}</legend>
         <input type="text" value={{ h }} readonly>
         <input type="text" value={{ m }} readonly>
         <input type="text" value={{ t }} readonly><br><br>
      </fieldset>
   {% endfor %}

我只是将'放在值字段中并工作了

   {% for n, h, m, t in zippado %}
      <fieldset>
         <legend>{{ n }}</legend>
         <input type="text" value='{{ h }}' readonly>
         <input type="text" value='{{ m }}' readonly>
         <input type="text" value='{{ t }}' readonly><br><br>
      </fieldset>
   {% endfor %}

request.values / request.form问题以在烧瓶上获取带有空格字符的值
