    在 Google App Engine 设置 Application Identifier 的规则

    Select an Application Identifier for Google App Engine

    注册 Google App Engine 之后,在填写 Application Identifier 的时候,你是不是很头痛?怎么这么多 id 都不能用?总是提示:

    Sorry, "xxxx" is not available. Application Identifiers may contain only numbers, lowercase letters or hyphens and must be between 1 and 32 characters.
    你可能会说,不可能啊,这个 xxxx 应该只有我会用的啊,没那么快就被人抢注了吧?

    没错,别人没有抢注你的这个 id,而是你自己抢注的。

    因为,这个 Application Identifier 除了要满足上面提到的要求(1-32个字符,只能包含数字、小写字母或横杠)外,还不能与已有的 Google ID 重复或部分重复。

    这里说的 Google ID 不仅仅指你的 Gmail/Google Mail 的帐号,还包括 Google PagesPicasa Web Albums 的用户地址。

    另外,假如你的 Gmail 帐号是 firstname.lastname,那么,“点”前面的部分也不能用来注册 Application Identifier

    ps. 凡是被用掉的 Google Pages 或 Picasa Web Albums 地址,都是不能用来注册 Gmail/Google Mail 帐号的。

    总觉得 Google 这样做会浪费很多资源。不过,他这样做也有他的道理。

    祝大家都能抢到一个好的 id!

    这样,你就能获得一个形如 application-id.appspot.com 的地址了。

    ps. 昨天终于学会怎么用这个 Google App Engine 了,上传了一个最简单的页面,大家可以去看看:http://donau.appspot.com/
