3.报错：
4.解决：将请求参数转换成json
page = 1
category_id = str(i['category_id'])
formdata = {
'attributes':'',
'categoryId':category_id,
'keyword':'',
'manufacturerId':'0',
'pageIndex':str(page),
'pageSize':'12',
'productId':'0',
'searchProductTypeEnum':'2',
'searchRelation: {clientType':'4}',
'sort':'"[{"RankScore":"desc"}]"',
}
req_body = json.dumps(formdata)
yield scrapy.Request(url=self.url, method="POST", body=req_body, headers=self.headers,
meta={"category": i},
callback=self.get_detail, dont_filter=True)
5.成功响应
