当服务器绑定到特定IP(而非本地主机)时，如何使Google App Engine python SDK远程API与本地开发服务器配合使用? [英] How do I make Google App Engine python SDK Remote API work with local development server when server is bound to specific IP (not localhost)?

问题描述

在生产服务器上使用远程api(remote_api_shell.py)可以正常工作.但是，仅当开发服务器在localhost上提供服务时，它才能在开发服务器上工作.当服务器在特定IP(例如，dev_appserver.py --host=192.168.0.1)上运行时，它将不起作用.

Using the remote api (remote_api_shell.py) works fine on the production server. However, it only works on the development server when the development server is serving on localhost. It does not work when the server is running on specific IP (for example, dev_appserver.py --host=192.168.0.1).

这是使用Python SDK的.我敢肯定这适用于版本1.7.5.它不适用于1.7.6或1.8.0.

This is using the Python SDK. I'm kinda sure this worked on version 1.7.5. It does not work on 1.7.6 or 1.8.0.

这是一个具体情况:

运行服务器，并使其绑定到默认地址(localhost:8080):

Run the server and let it bind to the default address (localhost:8080):

/path/to/dev_appserver.py myapp/app.yaml
INFO     2013-05-25 19:11:15,071 sdk_update_checker.py:244] Checking for updates to the SDK.
INFO     2013-05-25 19:11:15,323 api_server.py:152] Starting API server at: http://localhost:39983
INFO     2013-05-25 19:11:15,403 dispatcher.py:98] Starting server "default" running at: http://localhost:8080
INFO     2013-05-25 19:11:15,405 admin_server.py:117] Starting admin server at: http://localhost:8000

启动远程API shell，它可以正常工作:

Start the remote API shell, and it works fine:

$ ./remote_api_shell.py -s localhost:8080
Email: x@x
Password: 
App Engine remote_api shell
Python 2.7.2+ (default, Jul 20 2012, 22:15:08)

但是，如果您使用指定的主机启动服务器:

However, if you start the server with a specified host:

/path/to/dev_appserver.py --host=192.168.0.1 myapp/app.yaml
INFO     2013-05-25 19:11:53,304 sdk_update_checker.py:244] Checking for updates to the SDK.
INFO     2013-05-25 19:11:53,554 api_server.py:152] Starting API server at: http://localhost:44650
INFO     2013-05-25 19:11:53,633 dispatcher.py:98] Starting server "default" running at: http://192.168.0.1:8080
INFO     2013-05-25 19:11:53,634 admin_server.py:117] Starting admin server at: http://localhost:8000

请注意，即使内容在http://192.168.0.1:8080中提供，它也会显示Starting API server at: http://localhost:44650.这是否表明您可以仅在本地主机上运行远程api?也许出于安全原因?

Notice it says Starting API server at: http://localhost:44650 even though the content is served at http://192.168.0.1:8080. Is this indicative that you can only run the remote api on localhost? Perhaps for security reasons?

此外，当您现在尝试remote_api_shell.py时，您只能使用有效帐户登录(不允许使用虚假帐户)，并且该错误立即终止并终止.

Also, when you try the remote_api_shell.py now, you can only log in with a valid account (no bogus accounts allowed) and it immediately errors and terminates.

控制台错误以

urllib2.HTTPError: HTTP Error 200: OK

和本地开发服务器输出:

and the local development server outputs:

INFO 2013-05-25 19:24:06,674 server.py:528] "GET /_ah/remote_api?rtok=90927106532 HTTP/1.1" 401 57

有人知道这是怎么回事吗?
除了在localhost上，是否可以访问远程API?
如果您的内容是在特定IP上提供的，是否不可能访问远程API(甚至在localhost上)?

Anyone know what's going on here?
Is it impossible to access the remote API other than on localhost?
Is it impossible to access the remote API (even on localhost) if your content is served on a specific IP?

推荐答案

似乎api服务器没有设置主机的选项. dev_appserver.py具有用于设置主机&的选项.内容和管理服务器的端口，以及api服务器专用的端口(api_port选项).示例:

It seems that api server doesn't have option to set host. dev_appserver.py has options to set host & port for content and admin server, and for api server only port (api_port option). Example:

dev_appserver.py --host=192.168.5.92 
                 --admin_host 192.168.5.92 --admin_port 9000 
                 --api_port 7000 .

运行此报告:

 api_server.py:153] Starting API server at: http://localhost:7000

 dispatcher.py:164] Starting server "default" running at: http://192.168.5.92:8080

 admin_server.py:117] Starting admin server at: http://192.168.5.92:9000

查看GAE dev_appserver的源代码，启动服务器的api_server方法的调用方是模块devappserver2.py，其行是:

Looking into the source of GAE dev_appserver, caller of the method of api_server which starts the server is module devappserver2.py and the line is:

apis = api_server.APIServer('localhost', options.api_port,
                             configuration.app_id)

您可以看到硬编码的主机名localhost.

You can see hardcoded host name localhost.

如果找不到很好的解决方法，我建议通过引入新选项和

If you find no good workaround, I would suggest to patch devappserver2.py by introducing a new option and report issue with patch attached?
