scrapy可以根据id提交到输入吗?

我有一个包含多个输入字段的内联网页,我需要scrapy使用网页“搜索产品”输入字段运行搜索,它的id为“searchbox”

我已经能够使用scrapy和beautiful soup锁定正确的搜索框,但我不确定如何将该数据正确地传递回scrapys表单提交功能。

在方法1中,我试图简单地将结果作为输入传递给scrapys formrequest.from_response函数,但它不起作用。

方法1-使用scrapy查找数据

#Search for products
def parse(self, response):

    ##Let's try search using scrapy only
    sel = Selector(response)
    results = sel.xpath("//*[contains(@id, 'searchBox')]")
    for result in results:
        print (result.extract())   #Print out what scrapy found
    return scrapy.FormRequest.from_response(results, formdata = {'Item': 'Whirlpool Washing Machine'}) #formdata is the data we are sending

方法2-使用beautiful soup查找数据

#Search for products
def parse(self, response):

    ##Let's try search using Beautiful Soup only
    soup = BeautifulSoup(response.text, 'html.parser')  
    product_search = []
    product_search.append(soup.find("input", id="searchBox")) 
    print(product_search) #Print what BS found
