Question

@ peter-hudec

重复使用相同的线程来解决遇到的新问题。我只能在每次登录时发出一个PUT / POST / GET请求。我无法重复使用登录'结果'对象。

我第一次请求获取Google日历中的所有活动。我检查自己的事件是否存在于Google日历中。如果它不存在，请将它们添加到Google日历中。

以下代码适用于单独的页面，但不适用于同一页面中的单个登录会话。

provider_name = 'google'
response = make_response()
print  'Response', response
result = authomatic_inst.login(WerkzeugAdapter(request, response), provider_name)
print 'Result', (result)

if result:
    if result.user:
        # Get user info
        result.user.update()

# Talk to Google Calendar API
        if result.user.credentials:
            response = result.provider.access('https://www.googleapis.com/calendar/v3/calendars/<CALENDARID>/events?key=<YOUR_API_KEY>', method='GET')
            if response.status == 200:
                items = response.data.get('items', {})

                ### <code to Check whether event exists in Google Calendar before adding it in>
                # IF event not in Google Calendar, add it 

                    body_json = json.dumps(event)
                    response = result.provider.access('https://www.googleapis.com/calendar/v3/calendars/<CALENDARID>/events?key=<YOUR_API_KEY>', method='POST', body=body_json, headers={'Content-Type':'application/json;charset=UTF-8'})
                    if response.status == 200:
                        res = response.data
                    return json.dumps(res)

下面的老问题：

我正在使用Authomatic来管理OAuth2.0登录。

我按照创作者发布的[answer] [1]。它适用于   YouTube授权，但不适用于Google日历。

http://peterhudec.github.io/authomatic/reference/classes.html#authomatic.Authomatic.access
if result:
        if result.user:
            # Get user info
            result.user.update()
 # Talk to Google Calendar API
            if result.user.credentials:
                response = result.provider.access('https://www.googleapis.com/calendar/v3/calendars/<calendarid>/events?key=<authkey>',
方法= 'GET'）如果response.status == 200：打印回复
return response
[GET请求] [2]，其中包含Google提供的互动示例 Calendar API是：
GET https://www.googleapis.com/calendar/v3/calendars/<CALENDARID>/events?key={YOUR_API_KEY}
Authorization:  Bearer ya29.BwGoAyc8yqYGzDz3FEPn-_zYU_EFLy0hiQzbv1h9zOnzlJe4dw1q68WNLuW7weJKNjtYYcy3P_AbsA
X-JavaScript-User-Agent:  Google APIs Explorer
我很确定我正在使用相同的请求，但我收到了错误代码   403禁止？

authomatic.login()方法仅为您获取result.user.credentials中包含的用户的访问令牌。然后，您可以使用凭据访问提供者API：

response = authomatic.access(result.user.credentials, 'https://example.com/api')
# Following uses the code above internally
response = result.provider.access('https://example.com/api')

每次要发出API请求时，都不需要完成登录过程。我建议将API调用移到一些不同的视图：

def login_view(request):
    response = HttpResponse()
    result = authomatic.login(DjangoAdapter(request, response),
                              provider_name)
    if result:
        if result.credentials:
            # You can serialize the credentials to move them across requests.
            # The best would be to store them to the DB with the user.
            request.session['credentials'] = result.credentials.serialize()
        return redirect('api-view')
    return response


def api_view(request):
    serialized_credentials = request.get('credentials')
    if serialized_credentials:

        # You can deserialize the credentials...
        credentials = authomatic.credentials(serialized_credentials)

        # ...and update them if they are about to expire soon
        # Google access tokens are valid for 6 months
        if credentials.expire_soon():
            response = credentials.refresh()
            if response.status == 200:
                request.session['credentials'] = credentials.serialize()

        # The access method accepts both serialized and
        # deserialized credentials.
        response = authomatic.access(credentials, 'https://example.com/api')

您可以阅读有关credentials in the docs的更多信息。还有一个Webapp2 based tutorial可以轻松移植到Django。

使用REST的Google Calendar API - 每个身份验证只有一个请求？
