scrapy登录没有工作

Question

当我调用表单帖子时我没有得到登录应该是因为输入名称就像数组，例如logn [username]和login [passwords]这就是为什么我不接受有一些方法来发送数组输入的名称？或者使用输入ID吗？

start_urls = ['https://b2b.fluidra.es/customer/account/login']

def parse(self, response):

    yield scrapy.FormRequest.from_response(
        response,
        formxpath='//form[@id="login-form"]',
        formdata={
            'login[username]': 'MISUSER@USER.COM',             
            'login[password]': 'XXXXXXXXXX'
        },
        callback=self.start_requests_action
    )

然后是为登录发送的表单的html代码
