问题描述

我想简单地发送给谷歌的托管模式sample.sentiment的请求。我无法弄清楚如何通过谷歌使用OAuth 2.0认证,而且我得到无尽的金额小时。如果你能提供给我的code到这将是有益的。以下是我工作过的。

I am trying to simply send a request to google's hosted model sample.sentiment. I cannot figure out how to authorize with Oauth 2.0 via google, and I am getting endless amounts of hours. If you could provide me the code to this is would be helpful. Here is what I am working off of.

client = Google::APIClient.new({:application_name => "CCE",:application_version => "1.0"} )
plus = client.discovered_api('prediction')

# Initialize OAuth 2.0 client
client.authorization.client_id = 'my client id'
client.authorization.client_secret = 'my client secret'
client.authorization.redirect_uri = 'my callback url'

client.authorization.scope = 'https://www.googleapis.com/auth/prediction'

# Request authorization
redirect_uri = client.authorization.authorization_uri

# Wait for authorization code then exchange for token
client.authorization.code = '....'
client.authorization.fetch_access_token!

# Make an API call
 result = client.execute(
   :api_method => plus.activities.list,
   :parameters => {'hostedModelName' => 'sample.sentiment', 'userId' => ''})

推荐答案

好了,在网络上的例子可能会有点混乱,但如果你想利用一台服务器 - 服务器通信 - 这意味着没有最终用户也没有浏览器是参与,那么下面code应该为你工作:

Well, the examples on the web may be a little confusing, but if you want to utilize a server-server communication - meaning that no end-user and no browser is involved, then the following code should work for you:

在prerequisites:

The prerequisites:


  • 您应该产生在你的谷歌API控制台服务帐户键。它会提示你下载一个私钥,你应该在一些地方保存在磁盘上,例如 client.p12 (或使用原来的名字,但为了清楚起见我将使用较短的一个)。

  • you should generate a "service account" key in your Google API Console. It will prompt you to download a private key, which you should store somewhere on your disk, for example as client.p12 (or use the original name, but for clarity I'll use the shorter one).
client = Google::APIClient.new(
  :application_name => "CCE",
  :application_version => "1.0"
)
prediction = client.discovered_api('prediction', 'v1.5')

key = Google::APIClient::KeyUtils.load_from_pkcs12('client.p12', 'notasecret')

client.authorization = Signet::OAuth2::Client.new(
  :token_credential_uri => 'https://accounts.google.com/o/oauth2/token',
  :audience => 'https://accounts.google.com/o/oauth2/token',
  :scope => 'https://www.googleapis.com/auth/prediction',
  :issuer => '..put here your developer email address from Google API Console..',
  :signing_key => key,
)
client.authorization.fetch_access_token!

# Now you can make the API calls
result = client.execute(...

值得注意的是, client.discovered_api 通话似乎需要的版本号。否则可能会抛出异常'NOTFOUND。

Worth noting is that client.discovered_api call seems to require the version number. otherwise it may be throwing an exception 'NotFound'.

该密码是真正的字符串' notasecret '!

The passphrase is really the string 'notasecret'!

另一件事:在API调用确保您调用适当的方法 - 托管模式,我相信你可以调用的唯一方法就是:的api_method => prediction.hostedmodels。predict 或这样的事情。我没有用托管的模型呢。

Another thing: in API call make sure that you call the proper method - for hosted models I believe the only method you can call is :api_method => prediction.hostedmodels.predict or something like this. I've not used hosted models yet. (see the API docs for details)

结果 client.execute 调用返回的可能是有趣的字段是:

The possibly interesting fields of the result returned by the client.execute call are:

result.status
result.data['error']['errors'].map{|e| e['message']} # if they exist
JSON.parse(result.body)

如果您检查他们,他们可能会显著帮助你在调试任何问题。

If you inspect them, they will probably help you significantly in debugging any problems.
