使用：

    def process_request(self, request, spider):
        driver = webdriver.PhantomJS()
        # driver = webdriver.Chrome()
        driver.get(request.url)
        body = driver.page_source
        input_first  = driver.find_element_by_id('stockID_')
        input_first.clear()

        input_first.send_keys('')

        button = driver.find_element_by_id('button')
        dataClick = button.click()
        print(dataClick)
        body = driver.page_source
        # driver.switch_to.frame('i_nr')
        # print("访问：", driver.page_source)
        return HtmlResponse(driver.current_url, body=body, encoding='utf-8')
