Python 2.7 试图用Scrapy FormRequest填充表单，意外结果

我正在尝试填写www.wetseal.com/Stores上的表单，该表单允许选择显示门店的州

<form action="http://www.wetseal.com/Stores?dwcont=C73689620" method="post" id="dwfrm_storelocator_state">
                    <fieldset>



                        <div class="form-row required ">            
                            <label for="dwfrm_storelocator_address_states_stateUSCA">               
                                <span>State</span>              
                                <span class="required-indicator">*</span>

                            </select>
                        </div>                          
                        <button type="submit" name="dwfrm_storelocator_findbystate" value="Search">
                            Search
                        </button>
                    </fieldset>
                </form>

当它开始发出FormRequest时，查看响应，一切似乎都正常：

但在回调方法中，我在响应中看到：

看起来像是在最后发出了GET请求，而url完全错误：

'http://www.wetseal.com/Search?q=&dwfrm_storelocator_findbystate=Search&dwfrm_storelocator_address_states_stateUSCA=AZ'

知道我做错了什么吗

谢谢

您正在使用

formname

但表单没有名称

尝试改用

formxpath='id（“dwfrm\u storelocator\u state”）

。

试试这个

states = response.xpath(
        ".//select[@id='dwfrm_storelocator_address_states_stateUSCA']//option[@value!='']/@value").extract()
    url = self.get_text_from_node(response.xpath("//form[@id='dwfrm_storelocator_state']/@action"))
    for state in states:
        form_data = {'dwfrm_storelocator_address_states_stateUSCA': state,
                     "dwfrm_storelocator_findbystate": "Search"}
        yield FormRequest(url,
                          formdata=form_data,
                          callback=self.your_Callback)

成功了！正如我所怀疑的，名字不能被使用，我认为Scrapy会聪明到可以同时查看“id”属性，但它不是：D，谢谢@Artur Gaspar

states = response.xpath(
        ".//select[@id='dwfrm_storelocator_address_states_stateUSCA']//option[@value!='']/@value").extract()
    url = self.get_text_from_node(response.xpath("//form[@id='dwfrm_storelocator_state']/@action"))
    for state in states:
        form_data = {'dwfrm_storelocator_address_states_stateUSCA': state,
                     "dwfrm_storelocator_findbystate": "Search"}
        yield FormRequest(url,
                          formdata=form_data,
                          callback=self.your_Callback)
