python传递json参数

python传递json参数

一般requests用

url = "http://.................."
data = {
    "page": "1",
}
response = requests.post(url=url, json=data).text

在scrapy里需注意：

def start_requests(self):
    start_url = "http://...................."
    for page_num in range(1, 2):
        data = {
            "page": str(page_num),
        }
        yield scrapy.Request(url=start_url, method="POST", body=json.dumps(data), headers={
            "Content-Type": "application/json"
        }, callback=self.list_parse)
