问题描述
我尝试使用Google服务帐户从我的AppENgine Java应用程序访问Fusion表。此代码片段用于获取OAuth访问令牌：
ArrayList< String> scopes = new ArrayList< String>（）;
scopes.add（https://www.googleapis.com/auth/fusiontables）;
DataAccessService fusionTablesService = EnvironmentServic.getEnvironmentService（）。getService（DataAccessService.class）;
String token = AppIdentityServiceFactory.getAppIdentityService（）。getAccessToken（scopes）.getAccessToken（）;
我能够成功获取访问令牌，但是当我尝试执行CREATE TABLE查询时， ：
< HTML>
< HEAD>
< TITLE>需要登入< / TITLE>
< / HEAD>
< BODY BGCOLOR =＃FFFFFFTEXT =＃000000>
< H1>需要登录< / H1>
< H2>错误401< / H2>
< / BODY>
< / HTML>
服务帐户是否适用于Fusion Tables？
Grant服务帐户的权限（在管理控制台中找到电子邮件地址）访问表。这可能会通过可能有助于作为此过程的起点。
$ b 2）登录一个有权访问该表的用户（或者您试图访问其数据的用户），并让他们授权访问该应用程序，有条腿的OAuth流量。如果您访问的是最终用户拥有的数据（例如：[email protected]），那么您可能需要这样做。
希望这个帮助。
I am trying to use Google Service Accounts to access Fusion table from my AppENgine Java App. This code snippet is used to obtain OAuth access token:
ArrayList<String> scopes = new ArrayList<String>();
scopes.add("https://www.googleapis.com/auth/fusiontables");
DataAccessService fusionTablesService = EnvironmentServic.getEnvironmentService().getService(DataAccessService.class);
String token = AppIdentityServiceFactory.getAppIdentityService().getAccessToken(scopes).getAccessToken();
I was able to successfully obtain access token, but when I am trying to execute CREATE TABLE query i got:
<HTML>
<HEAD>
<TITLE>Login required</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Login required</H1>
<H2>Error 401</H2>
</BODY>
</HTML>
Do service account works with Fusion Tables?
I'm not terribly familiar with Fusion Tables, but it is likely that you need to either:
1) Grant permission to the service account (the "email address" is found in the admin console) to access the table. This would probably happen through The sample at https://developers.google.com/appengine/articles/prediction_service_accounts may be helpful as a starting point for this process.
2) Log in a user who has access to the table (or whose data you're trying to access) and have them authorize access for the application using the three-legged OAuth flow. If you're accessing data that is owned by an end user (ex: [email protected]), then you'll probably need to do this.
Hope this helps.
