将Auth与端点一起使用

Question

我使用Google Cloud Endpoints定义了一个简单的API:

@Api(name = "realestate", version = "v1", clientIds = { com.google.api.server.spi.Constant.API_EXPLORER_CLIENT_ID }, scopes = {
        "https://www.googleapis.com/auth/userinfo.email",
        "https://www.googleapis.com/auth/userinfo.profile" })
public class RealEstatePropertyV1 {

    @ApiMethod(name = "create", path = "properties", httpMethod = HttpMethod.POST)
    public void create(RealEstateProperty property, User user)
            throws UnauthorizedException {
        if (user == null) {
            throw new UnauthorizedException("Must log in");
        }
        System.out.println(user.getEmail());
    }

}

然后我尝试用它来测试它API explorer.我激活了OAuth 2.0.但是当我执行请求时,User对象就是null.

Answer 1

该消息getCurrentUser: clientId not allowed表明与令牌关联的客户端 ID 是空字符串。这似乎不可能，并且可能是一个奇怪的错误/怪癖。

您应该检查请求中发送的令牌，它将位于Request类似的部分中

GET https://www.googleapis.com/oauth2/v2/userinfo?key={YOUR_API_KEY}

Authorization:  Bearer ya29....
X-JavaScript-User-Agent:  Google APIs Explorer

并且您的令牌是以 开头的令牌ya29.。您应该通过将令牌信息发送到 tokeninfo API 来确保检查令牌信息：
