获取去哪儿网酒店数据

URL = ‘https://hotel.qunar.com/napi/list‘

data = {
    "b": {
        "bizVersion": "17",
        "cityUrl": "beijing_city",
        "fromDate": "2020-03-07",
        "toDate": "2020-03-08",
        "q": "",
        "qFrom": 3,
        "start": 20,
        "num": 20,
        "minPrice": 0,
        "maxPrice": -1,
        "level": "",
        "sort": 0,
        "cityType": 1,
        "fromForLog": 1,
        "uuid": "",
        "userName": "",
        "userId": "",
        "fromAction": "",
        "searchType": 0,
        "locationAreaFilter": [],
        "comprehensiveFilter": []
    },
    "qrt": "h_hlist",
    "source": "website"
}

headers = {
  ‘authority‘: ‘hotel.qunar.com‘,
  ‘pragma‘: ‘no-cache‘,
  ‘cache-control‘: ‘no-cache‘,
  ‘accept‘: ‘application/json, text/plain, */*‘,
  ‘sec-fetch-dest‘: ‘empty‘,
  ‘user-agent‘: ‘Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.132 Safari/537.36‘,
  ‘content-type‘: ‘application/json;charset=UTF-8‘,
  ‘origin‘: ‘https://hotel.qunar.com‘,
  ‘sec-fetch-site‘: ‘same-origin‘,
  ‘sec-fetch-mode‘: ‘cors‘,
  ‘referer‘: ‘https://hotel.qunar.com/cn/beijing_city/?fromDate=2020-03-06&toDate=2020-03-07&cityName=%E5%8C%97%E4%BA%AC‘,
  ‘accept-language‘: ‘zh-CN,zh;q=0.9,en;q=0.8‘,
}

resp = requests.post(URL, headers=headers, data=data)

这样请求返回400.
研究发现，是因为data数据需要是字符串型才可以。

data =  json.dumps(data)

这样返回200

headers中referer 与 content-type 必须有。
