Question

我可以设置会话数据 / JSON“

me@air9:28:18 ⮀ ~ ⮀ curl -v -X POST http://127.0.0.1:5000 -d '{"email": "user@email.com", "password": "p"}' -H "Content-Type: application/json"

以下是检索会话数据的代码

    try:
        print session
        user = load_token(session['USER_TOKEN'])
    except ValueError:
        return redirect(url_for('/'))
    except:
        print repr(sys.exc_info())

当我用curl点击以下内容时

curl -v -b "session='DRRrrffY/WGHU80TJ++KY5UaoYU=?USER_TOKEN=UycuZUp3RndjRVJ3Q0FJQk1CZWVJY1pRVVNzSlpNSEo5cF9DZGw5Q1RaSGFUZU9PNTBObVp3U3lxanMyTzU2U3VtaEM4aXBKbXZtdXFNcExDVERiYVBzOUtIMF9maUJGQ0UudHA0NEsyd3ZxRWREaHlGQmw5cUNiclpVZnNFJwpwMQou'" http://127.0.0.1:5000/users/uuid/transactions

服务器日志打印

<SecureCookieSession {}>
(<type 'exceptions.KeyError'>, KeyError('USER_TOKEN',), <traceback object at 0x109994248>)

我做错了什么？

如何恢复会话数据？

Answer 1

我明白了。我所要做的就是在第一次登录时将会话cookie保存在文件中

curl -v -X POST http://127.0.0.1:5000 -d '{"email": "user@email.com", "password": "p"}' -H "Content-Type: application/json" -c cookies.txt* About to connect() to 127.0.0.1 port 5000 (#0)
*   Trying 127.0.0.1...
* connected
* Connected to 127.0.0.1 (127.0.0.1) port 5000 (#0)

< HTTP/1.0 200 OK

查看Added cookie session

中保存Cookie数据的cookies.txt

$cat cookies.txt
# Netscape HTTP Cookie File
# http://curl.haxx.se/docs/http-cookies.html
# This file was generated by libcurl! Edit at your own risk.

#HttpOnly_127.0.0.1 FALSE   /   FALSE   0   session "DRRrrffY/WGHU80TJ++KY5UaoYU=?USER_TOKEN=UycuZUp3RndjRVJ3Q0FJQk1CZWVJY1pRVVNzSlpNSEo5cF9DZGw5Q1RaSGFUZU9PNTBObVp3U3lxanMyTzU2U3VtaEM4aXBKbXZtdXFNcExDVERiYVBzOUtIMF9maUJGQ0UudHA0NEsyd3ZxRWREaHlGQmw5cUNiclpVZnNFJwpwMQou"

现在，当我将cookie数据发送到服务器

时

curl -v -b cookies.txt http://127.0.0.1:5000/users/uuid/transactions # see I am sending the file with -b option

我可以看到服务器接收会话数据

<SecureCookieSession {'USER_TOKEN': '.eJwFwcERwCAIBMBeeIcZQUSsJZMHJ9p_Cdl9CTZHaTeOO50NmZwSyqjs2O56SumhC8ipJmvmuqMpLCTDbaPs9KH0_fiBFCE.tp44K2wvqEdDhyFBl9qCbrZUfsE'}>
