Oauth for Google API示例使用Python / Django [英] Oauth for Google API example using Python / Django

问题描述

我试图让Oauth使用Python与Google API协同工作。我尝试过不同的oauth库，例如 oauth ， oauth2 和 djanog-oauth ，但我无法使其工作（包括提供的示例）。

I am trying to get Oauth working with the Google API using Python. I have tried different oauth libraries such as oauth, oauth2 and djanog-oauth but I cannot get it to work (including the provided examples).

对于调试Oauth，我使用Google的 Oauth Playground ，我研究过 API 和 Oauth文档

For debugging Oauth I use Google's Oauth Playground and I have studied the API and the Oauth documentation

对于一些图书馆，我正在努力获得正确的签名，其他图书馆我正在努力将请求令牌转换为授权令牌。如果有人可以使用上述图书馆之一向我展示Google API的工作示例，那真的可以帮助我。

With some libraries I am struggling with getting a right signature, with other libraries I am struggling with converting the request token to an authorized token. What would really help me if someone can show me a working example for the Google API using one of the above-mentioned libraries.

编辑：我的初始问题没有导致任何答案，所以我添加了我的代码。这个代码有两个可能的原因不起作用：

1）Google不授权我的请求令牌，但不太确定如何检测这个代码

2）访问签名令牌无效，但后来我想知道Google所期望的哪些oauth参数，因为我可以在第一阶段生成正确的签名。

My initial question did not lead to any answers so I have added my code. There are two possible causes of this code not working:
1) Google does not authorize my request token, but not quite sure how to detect this
2) THe signature for the access token is invalid but then I would like to know which oauth parameters Google is expecting as I am able to generate a proper signature in the first phase.

这是使用oauth2 .py和Django因此是HttpResponseRedirect。

This is written using oauth2.py and for Django hence the HttpResponseRedirect.

REQUEST_TOKEN_URL = 'https://www.google.com/accounts/OAuthGetRequestToken'
AUTHORIZATION_URL = 'https://www.google.com/accounts/OAuthAuthorizeToken'
ACCESS_TOKEN_URL = 'https://www.google.com/accounts/OAuthGetAccessToken'

CALLBACK = 'http://localhost:8000/mappr/mappr/oauth/' #will become real server when deployed

OAUTH_CONSUMER_KEY = 'anonymous'
OAUTH_CONSUMER_SECRET = 'anonymous'

signature_method = oauth.SignatureMethod_HMAC_SHA1()
consumer = oauth.Consumer(key=OAUTH_CONSUMER_KEY, secret=OAUTH_CONSUMER_SECRET)
client = oauth.Client(consumer)

request_token = oauth.Token('','') #hackish way to be able to access the token in different functions, I know this is bad, but I just want it to get working in the first place :)

def authorize(request):
    if request.GET == {}:
        tokens = OAuthGetRequestToken()
        return HttpResponseRedirect(AUTHORIZATION_URL + '?' + tokens)
    elif request.GET['oauth_verifier'] != '':
        oauth_token = request.GET['oauth_token']
        oauth_verifier = request.GET['oauth_verifier']
        OAuthAuthorizeToken(oauth_token)
        OAuthGetAccessToken(oauth_token, oauth_verifier)
        #I need to add a Django return object but I am still debugging other phases.

def OAuthGetRequestToken():
    print '*** OUTPUT OAuthGetRequestToken ***'
    params = {
    'oauth_consumer_key': OAUTH_CONSUMER_KEY, 
    'oauth_nonce':  oauth.generate_nonce(),
    'oauth_signature_method': 'HMAC-SHA1',
    'oauth_timestamp': int(time.time()), #The timestamp should be expressed in number of seconds after January 1, 1970 00:00:00 GMT.
    'scope': 'https://www.google.com/analytics/feeds/',
    'oauth_callback': CALLBACK,
    'oauth_version': '1.0'
    }

    # Sign the request.
    req = oauth.Request(method="GET", url=REQUEST_TOKEN_URL, parameters=params)
    req.sign_request(signature_method, consumer, None)

    tokens =client.request(req.to_url())[1]
    params = ConvertURLParamstoDictionary(tokens)
    request_token.key  = params['oauth_token']
    request_token.secret =  params['oauth_token_secret']
    return tokens

def OAuthAuthorizeToken(oauth_token):
    print '*** OUTPUT OAuthAuthorizeToken ***'
    params ={
    'oauth_token' :oauth_token,
    'hd': 'default'
    }
    req = oauth.Request(method="GET", url=AUTHORIZATION_URL, parameters=params)
    req.sign_request(signature_method, consumer, request_token)
    response =client.request(req.to_url())
    print response #for debugging purposes

def OAuthGetAccessToken(oauth_token, oauth_verifier):
    print '*** OUTPUT OAuthGetAccessToken ***'
    params = {
    'oauth_consumer_key':  OAUTH_CONSUMER_KEY,
    'oauth_token': oauth_token,
    'oauth_verifier': oauth_verifier,
    'oauth_token_secret': request_token.secret,
    'oauth_signature_method': 'HMAC-SHA1',
    'oauth_timestamp': int(time.time()),
    'oauth_nonce': oauth.generate_nonce(),
    'oauth_version': '1.0',    
    }

    req = oauth.Request(method="GET", url=ACCESS_TOKEN_URL, parameters=params)
    req.sign_request(signature_method, consumer, request_token)

    response =client.request(req.to_url())
    print response
    return req

def ConvertURLParamstoDictionary(tokens):
    params = {}
    tokens = tokens.split('&')
    for token in tokens:
        token = token.split('=')
        params[token[0]] = token[1]

    return params

推荐答案

我有OAuth在一个python App Engine应用程序中工作：

I have OAuth working in a python App Engine app:
