Ruby on rails: Google API dailyLimitExceededUnreg - google-api

Question

Hey guys I have an error when getting some tokens from google. Do you have any ideas about this error? And let me know how I can solve this error.
[{"domain"=>"usageLimits", "reason"=>"dailyLimitExceededUnreg", "message"=>"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.", "extendedHelp"=>"https://code.google.com/apis/console"}], "code"=>403, "message"=>"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup."}}
My fetching code:
def self.request_tokens(code)
Request.post('https://www.googleapis.com/oauth2/v4/token', {
client_id: 'XXXXXXXXXXXXXX',
client_secret: 'XXXXXXXXXXXXXX',
redirect_uri: 'http://localhost:8080',
grant_type: 'authorization_code',
code: code,
})
end
def self.request_profile(access_token)
Request.get("https://www.googleapis.com/plus/v1/people/me?access_token=#{access_token}")[:body]
end
Add:
I have already added API key like this.
def self.request_profile(access_token)
　　# Add api key but failed
Request.get("https://www.googleapis.com/plus/v1/people/me?access_token=#{access_token}?key=XXXXXXXXXXXXX")[:body]
　　# try like this but failed
plus = Google::Apis::PlusV1::PlusService.new
plus.key = 'XXXXXXXXXXXXX'
plus.authorization = access_token
end

Answer 1

It means exactly what it says. You're overusing Google's API, so they're not letting you use it for the rest of the day unless you sign up for an API key. https://code.google.com/apis/console, the link in your error, will let you do that.

Answer 2

"Daily Limit for Unauthenticated Use Exceeded. Continued use requires signup.",
Means that you are trying to access a Google api without being authenticated or using an api key (using a valid client). In order to access all google apis you must have created a project on Google developer console. If you are accessing public data you can use an api key if you are accessing private user data you will need to use Oauth2.
You appear to have tried to set the client id in your code. The issue is that its not being applied properly to your request. I am not a ruby dev so can not assist you in debugging your code how ever google has a number of ruby tutorials OAuth 2.0
as well as use api key
require 'google/apis/plus_v1'
plus = Google::Apis::PlusV1::PlusService.new
plus.key = 'api_key'
