我在使用请求库编写登录功能验收测试时遇到问题。登录是使用post方法实现的,我无法直接更改查询字符串并操纵URL。我想要做的是手动提交帖子数据,并让页面重定向到用户成功登录时会定期访问的页面。我想检索该页面的html并检查登录成功,如何我会这样做吗?
此方法失败:
data={'email': 'example@example.com', 'password': 'example'}
login_url="examplepage.com/signin"
request_data = requests.post(login_url, data, allow_redirects=True)
print request_data.content
这是resp.headers返回的内容:
{'content-length': '1124', 'date': 'Sun, 14 Apr 2013 16:12:51 GMT', 'set-cookie': 'session="+udnwfCkuAuFGp9QKOiU1YS2X1s=?_fresh=STAwCi4=&_id=Uyc3XHhkZVx4Y2J3T1x4YjBceDkxeFx4MWNceGFhXHhkNFx4OTMhKVx4MGJyJwpwMQou&csrf=Uyc2Mzk0YjVjZjMzMGZkMTNkY2NiM2EzZTZkYzgyMjhkY2IwOWQ2NmM3JwpwMQou"; Path=/; HttpOnly', 'content-type': 'text/html; charset=utf-8', 'connection': 'keep-alive', 'server': 'Werkzeug/0.8.3 Python/2.7.3'}
resp.content只返回登录页面的html:
<title>Web App</title>
</head>
<body>
<div>Web App: <a href="/home">Home</a>
| <a href="/signin">Login</a>
| <a href="/register">Register</a>
</div>

如果您想登录某个页面,我建议您创建会话,尽管有独立请求。如果您正确发送数据您应该检索一些会话cookie。我会检查它以确保您已登录。当脚本登录并获取cookie时,它还应检索包含目标页面的Location标头。尝试这样的事情:
import requests
data={'email': 'example@example.com', 'password': 'example'}
login_url="examplepage.com/signin"
s = requests.session()
resp = s.post(login_url,data)
#now s.cookies should contain session cookie if properly logged in
target = s.get(resp.headers['Location'])
但我认为问题可能与会话有关。

我的解决方案是在应用的CSRF_ENABLED
文件中将config.py
变量从 True 更改为 False 。一旦我更改了此设置,上面的代码实际上有效。顺便说一下,我正在Heroku上主持。

我这样做了:
if auth == True:
# fetch the login page in order to get the csrf token
cookieHandler = urllib2.HTTPCookieProcessor()
opener = urllib2.build_opener(urllib2.HTTPSHandler(), cookieHandler)
urllib2.install_opener(opener)
login_url = URL
login_page = opener.open(login_url)
# attempt to get the csrf token from the cookie jar
csrf_cookie = None
for cookie in cookieHandler.cookiejar:
if cookie.name == 'csrftoken':
csrf_cookie = cookie
break
if not cookie:
raise IOError("No csrf cookie found")
# login using the usr, pwd, and csrf token
login_data = urllib.urlencode(dict(
username = username, password = password,
csrfmiddlewaretoken = csrf_cookie.value))
req = urllib2.Request(login_url, login_data)
resp = urllib2.urlopen(req)
contents = resp.read()
target_download = target_url
status_code = urllib2.urlopen(target_download).getcode()
our_document = urllib2.urlopen(target_download).read()
return status_code, our_document
