Python 如何修复<；答复[404]>；发送post请求时出错

我想从站点获取数据，但响应只显示错误

我尝试将url改为http，这导致了405错误，并尝试将data=json.dumps（data）改为data=data，但都不起作用

import requests
import json
from bs4 import BeautifulSoup

request_url = 'https://www.kinds.or.kr/news/newsResult.do'

data = {"jsonSearchParam": {"indexName": "news", "searchKey": "sky", "searchKeys": [{}], "byLine": "", "searchFilterType": "1", "searchScopeType": "1", "mainTodayPersonYn": "", "startDate": "2019-05-06", "endDate": "2019-08-06", "newsIds": [
], "categoryCodes": [], "incidentCodes": [], "networkNodeType": "", "topicOrigin": ""}, "index-name": "news", "N": "", "search-keyword": "sky", "search-index-type": "news", "dict-type": "texanomy", "dict-concat": "OR"}

response = requests.post(request_url, data=json.dumps(data))

html = response.text

soup = BeautifulSoup(html, 'html.parser')

flist = soup.find_all('span')

print(response)

---

我希望得到正确的回复。

您的url似乎不正确。查看Firefox开发工具，正确的搜索URL是

https://www.kinds.or.kr/v2/news/search.do“

。参数“jsonSearchParam”需要是一个json字符串，因此我们在其上使用

json.dumps（）

：

import json
import requests
from bs4 import BeautifulSoup

# request_url = 'https://www.kinds.or.kr/news/newsResult.do'
request_url = 'https://www.kinds.or.kr/v2/news/search.do'   # <-- correct URL

d = {"indexName": "news", "searchKey": "sky", "searchKeys": [{}], "byLine": "", "searchFilterType": "1", "searchScopeType": "1", "mainTodayPersonYn": "", "startDate": "2019-05-06", "endDate": "2019-08-06", "newsIds": [], "categoryCodes": [], "incidentCodes": [], "networkNodeType": "", "topicOrigin": ""}
data = {"jsonSearchParam": json.dumps(d), "index-name": "news", "N": "", "search-keyword": "sky", "search-index-type": "news", "dict-type": "texanomy", "dict-concat": "+OR+"}

response = requests.post(request_url, data=data)
print(response)

soup = BeautifulSoup(response.text, 'lxml')
flist = soup.find_all('span')
print(flist)
