我正在寻找 Google App Engine (GAE) 的 OAuth2 库。

通过使用以下示例：https ://github.com/ndhu/GoogleAppEngineOAuth 我的环境：

  • GAE 版本：1.9.52
  • org.apache.amber 版本：版本 0.22-incubating

我有以下例外。从 oAuthClient 对象获取访问令牌时似乎会出现问题。并且这些警告在异常之前应该与 oAuthClient 构造有关。

p/s：即使在我将 org.apache.amber.oauth2 包更改为 org.apache.oltu.oauth2（版本 1.0.2）后，同样的警告和异常：

OAuthProblemException{error='invalid_request', description='Missing parameters: access_token', uri='null', state='null', scope='null', redirectUri='null', responseStatus=0, parameters={}}
    at org.apache.oltu.oauth2.common.exception.OAuthProblemException.error(OAuthProblemException.java:59)

有什么帮助吗？

在 oAuthClient.accessToken(...) 方法中将响应类从 GitHubTokenResponse 更改为 OAuthJSONAccessTokenResponse 后问题已解决。

那是因为 Apache oltu 上的文档已经过时了 https://cwiki.apache.org/confluence/display/OLTU/OAuth+2.0+Client+Quickstart

来自 Facebook 的访问令牌响应的交换 OAuth 代码现在采用 json 格式，例如：{"access_token":"","token_type":"bearer"}
