python - 带有 django-recaptcha 的新 Google ReCAPTCHA

Question

有没有一种简单的方法来调整 django-recaptcha 插件以使用新的 google re-captcha API？我已经更改了模板，并且验证码以写入方式显示，但验证不起作用。有谁知道如何以简单的方式解决这个问题？

Answer 1

或者自己制作：这是我的，我使用其他人作为模板/起点制作的。

import json
import urllib2, urllib

API_SERVER = "https://www.google.com/recaptcha/api/siteverify"


class  RecaptchaResponse(object):
    def __init__(self, is_valid, error_code=None):
        self.is_valid = is_valid
        self.error_code = error_code

    def __unicode__(self):
        print "%s, %s" % (self.is_valid, self.error_code)

    def __str__(self):
        return self.__unicode__()

    def get_error(self):
        if self.error_code and len(self.error_code):
            return self.error_code[0]


def submit(recaptcha_secret, recaptcha_response, remoteip=''):

    if not (recaptcha_secret and recaptcha_response and len(recaptcha_secret) and len(recaptcha_response) ):
        return RecaptchaResponse(is_valid=False, error_code='incorrect-captcha-sol')

    def encode_if_necessary(s):
        if isinstance(s, unicode):
            return s.encode('utf-8')
        return s

    params = urllib.urlencode({
        'secret': encode_if_necessary(recaptcha_secret),
        'response': encode_if_necessary(recaptcha_response),
        'remoteip': encode_if_necessary(remoteip)
    })

    request = urllib2.Request(
        url=API_SERVER,
        data=params,
        headers={
            "Content-type": "application/x-www-form-urlencoded",
            "User-agent": "reCAPTCHA Python"
        }
    )

    httpresp = urllib2.urlopen(request)
    return_values = json.loads(httpresp.read())
    print return_values

    if return_values.get('success', False):
        return RecaptchaResponse(is_valid=True)
    else:
        return RecaptchaResponse(is_valid=False, error_code=return_values.get('error-codes', ''))

相同的代码移植到 Python 3。我们在生产中使用它。如果您愿意，可以从 pypi/pip 下载。

我知道你的问题很老，但现在，你只需要在 settings.py 中写：

NOCAPTCHA = True

就是这样。
