使用Python请求库发送jquery AJAX GET请求 [英] Sending an jquery AJAX GET request with Python request library

问题描述

我有一个我需要抓取的网站，它正在使用jquery AJAX函数从服务器获取信息.我已经研究了一段时间的代码，并成功使用以下命令从服务器获得响应:

I have a website I need to scrape and it is using jquery AJAX function to get information from the server. I have been investigating the code for a while and I successfully get the response from server using:

data = {'part_number':'1234'}
r = $.ajax({
        type : 'GET',
        url : 'ajaxurl',
        data : data
    })

请注意，这是通过js控制台完成的，因此我已经登录.当我尝试在python中进行操作时，我当然需要先登录:

Note that this is done via js console so I am alreadt logged in. When I try to do it in python I need to login first of course:

import requests
headers = {'User-Agent': 'Mozilla/5.0','Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'}
payload = {'username':'me','password':'1234'}
link = 'login url'
session = requests.Session()
resp = session.get(link,headers=headers)
cookies = requests.utils.cookiejar_from_dict(requests.utils.dict_from_cookiejar(session.cookies))
resp = session.post(link,headers=headers,data=payload,cookies =cookies)

#until here sucesss!"############

url = "ajaxurl"
my_params={'part_number':'1234'}
r = session.get( url = url, data = my_params, cookies =cookies,headers =headers )

登录后的请求进行得很好，但是对于GET响应，我收到了BAD REQUEST400.我不知道如何格式化请求.我不知道ajax对我的请求有何作用.有人有什么想法吗?

The post request for login goes well but for the GET response I receive BAD REQUEST 400. I cannot figure out how to format my request. I don't know what ajax does to my request. Anyone has any ideas?

预先感谢！

推荐答案

解决了！ 我在标题中添加了'X-Requested-With': 'XMLHttpRequest'并做到了:

Solved it! I added 'X-Requested-With': 'XMLHttpRequest' to headers and did:

pn = '1234'
r = requests.get(ajaxurl + '?part_number=' + pn, headers=headers, cookies=cookies)

虽然不明白为什么:(
