Grails OAuth插件：无法在Google中创建新的日历事件

Question

I am using grails Oauth plugin. And I am unable to create a new event in google calendar.

Service code:

def addNewEvent(String calendarId){
    Token token=getGoogleAccessToken()
    def calendars = oauthService.postGoogleResource(token, "https://www.googleapis.com/calendar/v3/calendars/${calendarId}/events?key=${grailsApplication.config.oauth.providers.google.key}", [end:'2013-09-26', start: '2013-09-26', summery: 'Testing'])
} 

Logs:

When I make this call via Google api Explorer , it is working.

Can anyone please give me some idea how to create a calendar event or where I am wrong?

Answer 1

On a first look, bodyParameters as per the api looks different. end and start are nested objects.

Shouldn't you try with the below bodyParameters :

['end.date':'2013-09-26', 'start.date':'2013-09-26', summary:'Testing']

You can also try

[end:[date:'2013-09-26'], start:[date:'2013-09-26'], summary:'Testing']

Also rectify summery with summary .

I can look into it in detail if the above is not the reason of discrepancy.

UPDATE
I was able to replicate your issue. After digging for a long period of time, found that grails oauth plugin does not support Google Oauth 2 API. There has been a pull request submitted for the same.

You can use the changes provided by the pull request or directly use scribe with the latest Google2Api as mentioned in this fork and as an example in detail.

Definitely, the parameter map was an issue, the above setup for end date, start date and summary has to be used. I am looking into it as well to see if I can successfully provide a working example for the same in groovy or as a Grails project in github. I would also see how the pull request affects the plugin. BTW, I tested with Oauth v2.2.1 plugin.

Hope that helps, will keep this answer updated as and when I proceed further.

Answer 2

I tried google API console to create a quick event and it create an event in my calander. I tried this in sample application.

def google() {
    Token token = (Token) session[oauthService.findSessionKeyForAccessToken('google')]
    def text = "Test Data".encodeAsURL()
    def calendarId = "asd@xyz.com".encodeAsURL()
    def calendars = oauthService.postGoogleResource(token, "https://www.googleapis.com/calendar/v3/calendars/${calendarId}/events/quickAdd?text=${text}&sendNotifications=true&key=${grailsApplication.config.oauth.providers.google.key}")
    def calendarsJSON = JSON.parse(calendars.body)
    render calendarsJSON.toString()
}

Above code successfully create an event with name Test Data for one hour in my google calendar.

I am trying to create an event for specific time. I will update this post after creating event successfully. And these are my logs.
