服务帐户无法与协调API使用。 [这是因为协调API需要验证的API用户有一个坐标许可，但它不可能附加一个坐标许可给服务帐户]

Service accounts cannot be used with the Coordinate API. [this is because the Coordinate API requires authenticated API users to have a Coordinate license, but it is not possible to attach a Coordinate license to a service account]

您可以使用Web服务器的流量，而不是，请看下面的示例。

You can use the web server flow instead, please find the sample below.

刷新令牌可以通过OAuth2游乐场检索：

A refresh token can be retrieved by using the OAuth2 Playground:

• 在API控制台，添加OAuth园地网址， https://developers.google.com/oauthplayground一>，作为授权的 重定向URI（我们需要当我们检索刷新令牌在 OAuth的游乐场，下同）
• 转到OAuth的游乐场，在一个浏览器会话，有你的API的用户身份验证（该用户需要有一个协调的许可）。 确保提供 你自己OAuth2客户端ID（设置>使用您自己的OAuth凭证）。 否则，你刷新令牌将被捆绑到OAuth2操场的 内部OAuth2客户端ID，并会在你需要使用被拒绝 与自己的客户端ID刷新令牌来获得访问令牌。
• 使用范围 https://www.googleapis.com/auth/coordinate 在步骤1， 点击授权的API在第2步，点击兑换授权codeS 令牌
• 复制刷新令牌在code。保证它的安全。
• 在此刷新令牌不会过期，所以您的应用程序将保持认证。

• In the APIs Console, add the OAuth Playground URL, https://developers.google.com/oauthplayground, as an authorized redirect URI (we’ll need that when we retrieve a refresh token in the OAuth Playground, below)
• Go to the OAuth Playground, in a browser session that has your API user authenticated (this user needs to have a Coordinate license). Make sure to provide you own OAuth2 client ID (Settings > Use your own OAuth credentials). Otherwise, your refresh token will be tied to the OAuth2 playground's internal OAuth2 client ID, and will be rejected when you want to use the refresh token with your own client IDs to get an access token.
• Use the scope https://www.googleapis.com/auth/coordinate In Step 1, hit "Authorize the API" In Step 2, hit "Exchange Authorization codes for tokens"
• Copy the refresh token in your code. Keep it secure.
• This refresh token does not expire, so your app will stay authenticated.
