发布请求500错误Python请求Web抓取

标签： python-3.x web-scraping python-requests http-post

过去，我使用请求库和此处使用的方法抓取了许多站点，但由于某些原因，尽管我可以在浏览器中访问信息，但该站点仍返回500错误。

以下是他们所有IT职位与Progressive的工作委员会的链接：https://progressive.taleo.net/careersection/2/jobsearch.ftl?lang=en#

这是我的代码：

from bs4 import BeautifulSoup
import requests
import json


url = "https://progressive.taleo.net/careersection/rest/jobboard/searchjobs?lang=en&portal=101430233"

使用Chrome工具，您可以查看XHR请求，并看到可以向我的代码中的url发送一个发布请求，并且该请求应返回一个包含所有职位空缺的JSON对象。相反，我不断收到500错误，除了“ Request Failed”（请求失败）或其他可能导致影响的信息外，没有其他特定信息。

如果有人可以阐明这个问题，我将不胜感激。我希望能够从网站上抓取所有职位。

P.S。我离开了评论部分，因为我还包括其他标题，但似乎没有一个起作用。

答案 0 :(得分：2)

您似乎需要设置他的time zone标头：

import requests

url = "https://progressive.taleo.net/careersection/rest/jobboard/searchjobs?lang=en&portal=101430233"

headers = {
    'Content-Type': 'application/json',
    'tz': 'GMT+00:00',
}

data = '{"multilineEnabled":false,"sortingSelection":{"sortBySelectionParam":"3","ascendingSortingOrder":"false"},"fieldData":{"fields":{"KEYWORD":"","JOB_TITLE":"","JOB_NUMBER":""},"valid":true},"filterSelectionParam":{"searchFilterSelections":[{"id":"POSTING_DATE","selectedValues":[]},{"id":"LOCATION","selectedValues":["213860137526","209460137526"]},{"id":"JOB_FIELD","selectedValues":["4460472188"]},{"id":"JOB_SCHEDULE","selectedValues":[]}]},"advancedSearchFiltersSelectionParam":{"searchFilterSelections":[{"id":"ORGANIZATION","selectedValues":[]},{"id":"LOCATION","selectedValues":[]},{"id":"JOB_FIELD","selectedValues":[]},{"id":"URGENT_JOB","selectedValues":[]},{"id":"EMPLOYEE_STATUS","selectedValues":[]}]},"pageNo":1}'


def test_post(url):
    dirty = requests.post(url, headers=headers, data=data)
    print(dirty.headers)
    print(dirty.status_code)
    clean = dirty.json()
    print(clean)

test_post(url)

输出：
