[Python知识库]requests跨域登录不了问题解决

requests 模块去访问登录Django web项目时因跨域问题登录不了，网上大部分解决方案是关闭Django内部的跨域配置，真是服了，这里我用的是请求端的解决方案。

跨域请求登录不成功主要配置有两个
1.header头中需要加Cookie：crsftoken=xxxxxxx

	urlcsrf = "http://10.197.24.60:7100/users/user_login/"
    result = requests.get(url=urlcsrf)
    csrfcookie = requests.utils.dict_from_cookiejar(result.cookies)['csrftoken']
    headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36",
        "cookie": "csrftoken=%s" % csrfcookie}

2.post请求中data需要加 csrfmiddlewaretoken 参数

	soup = BeautifulSoup(result.content, "html.parser")
    authenticity_token =soup.find('input',{'name':'csrfmiddlewaretoken'}).get("value")
    data ={"username":"F455437","password":"dsfsdg123.","csrfmiddlewaretoken":authenticity_token}
    r = requests.post(url=urlcsrf,data=data,headers=headers)

完整代码

import  requests

if __name__ == '__main__':
    urlcsrf = "http://10.197.24.60:7100/users/user_login/"
    result = requests.get(url=urlcsrf)
    csrfcookie = requests.utils.dict_from_cookiejar(result.cookies)['csrftoken']
    headers = {
        "User-Agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36",
        "cookie": "csrftoken=%s" % csrfcookie}
    soup = BeautifulSoup(result.content, "html.parser")
    authenticity_token =soup.find('input',{'name':'csrfmiddlewaretoken'}).get("value")
    data ={"username":"F1238775","password":"Whc159357.","csrfmiddlewaretoken":authenticity_token}
    r = requests.post(url=urlcsrf,data=data,headers=headers)
    print(r.status_code)
    print(r.text)

返回状态200成功登录并打印
