Question

我在Google App Engine中的托管虚拟机上运行Sails.js（v0.11.0），一切正常 如果我禁用套接字 。我正在使用默认的Sails项目，一个模型（用户）没有自定义属性，只是在我的浏览器中访问主页。我在Chrome的控制台窗口中看到以下内容;

WebSocket connection to 'ws://localhost:8080/socket.io/?__sails_io_sdk_version=0.11.0&__sails_io_sdk_platform=browser&__sails_io_sdk_language=javascript&EIO=3&transport=websocket&sid=GShPZd_tjzqnrigNAAAA' failed: Error during WebSocket handshake: 'Upgrade' header is missing
sails.io.js:143 

  |>    Now connected to Sails.
\___/   For help, see: http://bit.ly/1DmTvgK
        (using browser SDK @v0.11.0)



4(index):1 Font from origin 'http://sailsjs.org' has been blocked from loading by Cross-Origin Resource Sharing policy: The 'Access-Control-Allow-Origin' header contains the invalid value ''. Origin 'http://localhost:8080' is therefore not allowed access.

sails.io.js:143  ====================================
sails.io.js:143  Socket was disconnected from Sails.
sails.io.js:143  Usually, this is due to one of the following reasons:
 -> the server was taken down
 -> your browser lost internet connectivity

        Socket is trying to reconnect to Sails...

'缺少升级标头'似乎可能是罪魁祸首，但我不明白如何从Socket.io要求更改标头，我有一个app.yaml文件，只允许传递所有流量帆。

#app.yaml
module: default
version: 1
runtime: custom
api_version: 1
vm: true
manual_scaling:
    instances: 1

handlers:
    - url: /.*
    script: app.js

任何帮助都非常感谢！

干杯！ R上。

我认为你无法使用Sails＆＃39;开箱即用的网络套接字。谷歌应用引擎不是我熟悉的东西，但似乎你需要将他们的API用于网络套接字。见这个例子：

在做了一些更多的讨论之后，我最终遇到了这个帖子，这几乎与这个帖子重复，应该给你一些更多的线索。简短的回答是你需要一个单独的谷歌管理虚拟机运行你的网络套接字服务，然后你直接通过IP地址访问它，这似乎带来了使用Sails的所有乐趣。
