如何通过运行python脚本在Opencart中添加产品？

Question

我想刮阿里巴巴的产品，并希望在我的网站上显示。我已经用scrapy python3写了完整的代码。 当客户在搜索栏中搜索时，脚本将运行并显示所搜索的产品。这是我的代码

import scrapy
import csv
import os


class AlibabaCrawlerSpider(scrapy.Spider):
    name = 'alibaba_crawler'
    allowed_domains = ['alibaba.com']
    start_urls = ['http://alibaba.com/']

    def start_requests(self):
        """Read keywords from keywords file amd construct the search URL"""

        with open(os.path.join(os.path.dirname(__file__), "../resources/keywords.csv")) as search_keywords:
            for keyword in csv.DictReader(search_keywords):
                search_text=keyword["keyword"]
                url="https://www.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&SearchText={0}&viewtype=G".format(
                    search_text)
                # The meta is used to send our search text into the parser as metadata
                yield scrapy.Request(url, callback = self.parse, meta = {"search_text": search_text})


    def parse(self, response):

            yield {

                'product_link': product_link,
                'search_text': search_keyword
}

在键盘上搜索时，代码会在页面上搜索整个产品。 请最好给出任何代码或例子。你知道吗
