一、 文本域和单选按钮

前端 文本域和单选按钮表单获取方法一样

<form class="form-horizontal" method="post">
    <div class="form-group">
      <label for="username" class="col-sm-2 control-label">Username</label>
      <div class="col-sm-10">
        <input type="text" class="form-control" id="username" name="username" placeholder="Username"     autofocus="" >
      </div>
    </div>
....
...
 <div class="row">
    <div class="col-sm-2 col-sm-offset-2">
        <input name="sex" value="M" type="radio"  checked="checked"> 男
    </div>
 <div class="col-sm-2 ">
            <input name="sex" value="F" type="radio"> 女
        </div>                    
   </div>
</form>

pyhon 后端用request.values.get("name") 去获取

if request.method == "POST":   
    username = request.values.get("username")
    sex = request.values.get("sex")

二、多选按钮checkbox

<div class="row">
    <div class="col-sm-2 ">
    <label>
        <input name="s_option" value="basketball" type="checkbox"> 篮球
    </label>
</div>
<div class="col-sm-2 ">
    <label>
    <input name="s_option" value="football" type="checkbox"> 足球
    </label>
</div>
<div class="col-sm-2 ">
    <label>
        <input name="s_option" value="badminton"  type="checkbox"> 羽毛球
    </label>
</div>
</div>

后端使用request.values.getlist("s_option") 去获取，获取的value会组成一个列表

s_option =  request.values.getlist("s_option")
for s in s_option:
    pass

三、select 下拉框

前端表现形式

<select class="form-control" name="manufacturer" id="manufacturer">
    <option></option>
    <option selected="selected">--请选择厂家--</option>
    <option >HP</option>
    <option >Huawei</option>
   <option >Inspur</option>
</select>

pyhon 后端也是用request.values.get("name") 去获取

四 、获取前端传输过来的json

request.json 返回的是一个字典

request.json.get("key",'')

curl模拟

curl -i -H "Content-Type: application/json" -X POST -d '{"title":"Read a book"}'
