Google App Engine

Install Google App Engine SDK

install SDK: curl https://sdk.cloud.google.com/ | bash
restart your shell, sign in to Google Cloud Platform: gcloud auth login,
install App Engine package for Python: gcloud components update gae-python

Follow the tutorial in GAE document

Caution

data store read quota非常低，每天只有五万次，每读一行都算一次读操作，很可能一不小心就超了，然后你当天就再也读不了了，除非你开启付费功能。建议热点数据用memcache。

大局域网相关

头两个命令均需翻墙。第三个命令不需要翻墙，我的环境上如果翻墙直接报错：ERROR: (gcloud.components.update) Failed to fetch component listing from server. Check your network settings and try again.

第二步建议使用gcloud auth login --no-launch-browser，避免不必要的麻烦（本来是可以自动切换挺方便的，呵呵），登录时可能会遇到问题：

    raise ServerNotFoundError("Unable to find the server at %s" % conn.host)
httplib2.ServerNotFoundError: Unable to find the server at accounts.google.com

sdk中验证时没有给httplib2设置代理，我们需要hack代码手动添加代理，根据错误堆栈信息，找到client.py的1825行，在此之前加上如下内容：

    import socks
    http.proxy_info = httplib2.ProxyInfo(socks.PROXY_TYPE_HTTP, '127.0.0.1', 8087)
    http.disable_ssl_certificate_validation = True

头两行指定使用goagent的代理地址，第三行指定关闭ssl证书验证，觉得危险的请另寻出路。证书问题可能跟goagent的证书设置有关系，我的环境上不改就报：httplib2.SSLHandshakeError: [Errno 1] _ssl.c:510: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed。

改完后执行gcloud auth login --no-launch-browser，必须用新生成的code进行验证。登录成功会提示gcloud config set project PROJECT。

google有效ip获取方式

有很多版本可供选择：

https://code.google.com/p/goagent/issues/detail?id=14644，#31亲测可用
https://github.com/PeerXu/google-ip-explorer，未验证

appspot无法访问

将goagent/local/proxy.ini中profile/ipv4段下的appspot设置为.appspot.com = google_hk,forcehttps,fakehttps

google-analytics无法访问

访问https://www.google.com.hk/analytics/作为替代

gae不识别goagent证书

使用goagent代理上传gae应用时会报证书错误，fancy_urllib.InvalidCertificateException: Host 127.0.0.1:8087 returned an invalid certificate (_ssl.c:504: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed)，将goagent/local/CA.crt中的证书拷贝到google_appengine/lib/cacerts/cacerts.txt末尾即可，详见原文
