使用Requests和Django从脚本登录网页 [英] Login to webpage from script using Requests and Django

问题描述

我已经用Django编写了一个Web应用程序。我需要将一些数据从python脚本发布到表单。禁用登录后，帖子（r2）可以正常工作。我的请求对于登录名（r1）正常工作，但是对于表单发布（r2）现在却出现404错误。该登录名似乎未转移到第二个请求。 csrftoken和sessionid被硬编码用于测试，因为它无法识别它们。相关代码（已删除网址库）：

I have written a web application in Django. I need to post some data to a form from a python script. The post (r2) works correctly when login is disabled. I have the request working correctly for the login (r1), but it gives me a 404 error now for the form post (r2). The login doesn't appear to be carried over to the second request. The csrftoken and sessionid are hardcoded for testing because it wasn't recognizing them. Relevant code (url base removed):

url_login='../pecasRunLog/accounts/login/'
url_add_run='../pecasRunLog/model/'+region+'/add_run/'

client = requests.session()
client.get(url_login)
csrftoken = client.cookies['csrftoken']
login_data = {'username':user,'password':password, 'csrfmiddlewaretoken':csrftoken, 'next': '/pecasRunLog/'}
r1=client.post(url_login,data=login_data)

payload={'model_region':region_id,'scendir':scendir, 'mapit_scenario': schema, 'run_name':schema+timestamp, 'run_computer_name':os.environ['COMPUTERNAME'], 'run_computer_ip':get_lan_ip(), 'declared_user':declared_user, 'logged_in_user':getpass.getuser(), 'sd_schema':schema, 'sd_database':database, 'sd_host':get_lan_ip(), 'sd_port':pgport,'mapit_schema':schema, 'mapit_database':database, 'mapit_host':get_lan_ip(), 'mapit_port':pgport,'start_date':start_date, 'start_time':start_time, 'end_date':end_date, 'end_time':end_time,'logged_manually':3, 'csrfmiddlewaretoken':csrftoken, 'sessionid':'jtvv50cs3iyo9bjthbr2diujfmrrlsnf'}
r2=requests.post(url_add_run,payload)

推荐答案

部分不起作用是因为 r2 需要让返回的Cookie r1 。这可能无法解决，但是如果没有进行至少 的更改，就不可能工作。为此，您可以在整个脚本中使用相同的会话，也可以在第一个请求之后将cookie传递给每个请求。

It is not working in part because r2 needs to have the cookies returned by r1. This may not fix it, but it is unlikely to work without making at least this change. To do this, you could use the same session throughout the script, or pass the cookies to each request after the first one.

这是在整个会话中使用会话的样子像这样：

Here is what using a session throughout might look like:

url_login='../pecasRunLog/accounts/login/'
url_add_run='../pecasRunLog/model/'+region+'/add_run/'

client = requests.session()
client.get(url_login)
csrftoken = client.cookies['csrftoken']
login_data = {'username':user,'password':password, 'csrfmiddlewaretoken':csrftoken, 'next': '/pecasRunLog/'}
r1=client.post(url_login,data=login_data)

payload={'model_region':region_id,'scendir':scendir, 'mapit_scenario': schema, 'run_name':schema+timestamp, 'run_computer_name':os.environ['COMPUTERNAME'], 'run_computer_ip':get_lan_ip(), 'declared_user':declared_user, 'logged_in_user':getpass.getuser(), 'sd_schema':schema, 'sd_database':database, 'sd_host':get_lan_ip(), 'sd_port':pgport,'mapit_schema':schema, 'mapit_database':database, 'mapit_host':get_lan_ip(), 'mapit_port':pgport,'start_date':start_date, 'start_time':start_time, 'end_date':end_date, 'end_time':end_time,'logged_manually':3, 'csrfmiddlewaretoken':csrftoken, 'sessionid':'jtvv50cs3iyo9bjthbr2diujfmrrlsnf'}
r2=client.post(url_add_run,payload)

在整个脚本中传递的cookie如下所示：

Here is what passing cookies throughout the script might look like:

url_login='../pecasRunLog/accounts/login/'
url_add_run='../pecasRunLog/model/'+region+'/add_run/'

r0 = requests.get(url_login)
csrftoken = r0.cookies['csrftoken']
login_data = {'username':user,'password':password, 'csrfmiddlewaretoken':csrftoken, 'next': '/pecasRunLog/'}
r1=requests.post(url_login,data=login_data,cookies=r0.cookies)

payload={'model_region':region_id,'scendir':scendir, 'mapit_scenario': schema, 'run_name':schema+timestamp, 'run_computer_name':os.environ['COMPUTERNAME'], 'run_computer_ip':get_lan_ip(), 'declared_user':declared_user, 'logged_in_user':getpass.getuser(), 'sd_schema':schema, 'sd_database':database, 'sd_host':get_lan_ip(), 'sd_port':pgport,'mapit_schema':schema, 'mapit_database':database, 'mapit_host':get_lan_ip(), 'mapit_port':pgport,'start_date':start_date, 'start_time':start_time, 'end_date':end_date, 'end_time':end_time,'logged_manually':3, 'csrfmiddlewaretoken':csrftoken, 'sessionid':'jtvv50cs3iyo9bjthbr2diujfmrrlsnf'}
r2=requests.post(url_add_run,payload,cookies=r1.cookies)

如果以上两种方法均无效，请尝试仔细查看Cookie，也许您会发现问题所在。

If neither of these works, try looking carefully at the cookies, and maybe you'll spot the problem.
