做了python爬取豆瓣电影程序，但是一直出错

import requests
import json
if __name__ == "__main__":
    url = 'https://movie.douban.com/j/search_subjects'    # 指定URL
    params = {
        'type':'movie', 'tag':'%E5%96%9C%E5%89%A7','sort':'recommend', 'page_limit':'20',
        'page_start':'0'
    }
    headers = {
        'User Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3947.100 Safari/537.36'
    }  # UA伪装
    response = requests.get(url=url, params=params, headers=headers)    # get请求
    # 获取响应数据
    list_data = response.json()
    fp = open('./douban.json', 'w', encoding='utf-8')
    json.dump(list_data, fp=fp, ensure_ascii=False)
    print('保存成功！！！')

我也爬过豆瓣，应该是你直接用 response.json 这个用法不对，应该将 response.text 转成 JSON：

import requests
import json

url="https://movie.douban.com/j/search_subjects?type=movie&tag=%E7%83%AD%E9%97%A8&page_limit=50&page_start=0"
headers = {
"User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/81.0.4044.122 Safari/537.36",
"Referer":"https://movie.douban.com/"
}
response = requests.get(url,headers=headers)

# loads as json
result = json.loads(response.text)

# get subjects 
subjects = result['subjects']


def itemInfo(item):
    info = '{},{},{},{}\r\n'.format(item['title'], item['rate'],item['url'],item['cover_x'])
    return info

# write to file
f1 = open('E:/film.log','w',encoding='utf-8')
for item in subjects:
    print(itemInfo(item))
    f1.write(itemInfo(item))

结果：

楼主你的这个问题解决了吗？
