rweibo 的 OAuth 授权失败... 怎么 debug？

发布页没人维护啊。。。不知道怎么办了。。。

OS X 10.9.2, R 3.0.3, RStudio 0.98.501, Rweibo 0.2-7, Safari 7.0.2, Mac 上装了 Little Snitch, 不过没跳窗口，应该没有被拦截

> roauth <- createOAuth(app_name = "xxxxxxx", access_name = "rweibo")
# The port of help server was set to 80
starting httpd help server ...
Please input the codes here
CODE:

Safari 上地址栏是 https://api.weibo.com/oauth2/authorize?client_id=xxxxxxxxx&response_type=code&redirect_uri=http://127.0.0.1/library/Rweibo/doc/callback.html 窗口标题：第三方授权错误 网页内容：
访问出错了！
你所访问的站点在新浪微博的认证失败，请你联系{测试微博号}或者稍后再试。
(error:redirect_uri_mismatch)

网页上没有出现code。然后在 RStudio 按了几个回车。

starting httpd help server ... done
