我正在尝试设置Web套接字以通过Nginx进入Phoenix应用程序,但不断收到403错误。任何人都可以建议正确的配置以使这项工作在生产中工作 - 开发环境很好。
我的 Nginx conf:
upstream phoenix {
server 127.0.0.1:4000 max_fails=5 fail_timeout=60s;
}
server {
server_name <app-domain>;
listen 80;
location / {
allow all;
# Proxy Headers
proxy_http_version 1.1;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_set_header X-Cluster-Client-Ip $remote_addr;
# The Important Websocket Bits!
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_pass http://phoenix;
}
}
我的产品:
use Mix.Config
config :logger, level: :info
config :phoenix, :serve_endpoints, true
config :app, App.Endpoint,
http: [port: 4000],
url: [host: "127.0.0.1", port: 4000],
root: '.',
cache_static_manifest: "priv/static/manifest.json",
server: true
config :app, App.Repo,
username: System.get_env("MONGO_USERNAME"),
password: System.get_env("MONGO_PASSWORD"),
database: "template",
hostname: "localhost",
pool_size: 10
如有必要,我可以根据需要提供任何其他信息。
该应用程序可以通过域名很好地访问,最后一个也是唯一剩下的问题是让 Web 套接字工作。
非常感谢任何能为我指明正确方向的人。
我遵循了凤凰城网站的指南。Exrm 发布 - 凤凰城
你的nginx.config缺少这个:
# The following map statement is required
# if you plan to support channels. See https://www.nginx.com/blog/websocket-nginx/
map $http_upgrade $connection_upgrade {
default upgrade;
'' close;
}
将版本发送到我的服务器后,在本地机器中生成版本时,我也遇到了一些错误。
因此,我建议您在服务器环境中生成版本。
编辑:
浏览器控制台中的错误:
ws://phoenix.hollyer.me.uk/socket/websocket?token=&vsn=1.0.0' failed: Error during WebSocket handshake: Unexpected response code: 403
这可能是这个错误。您应该尝试在服务器中启动控制台:
[error] Could not check origin for Phoenix.Socket transport.
This happens when you are attempting a socket connection to
a different host than the one configured in your config/
files. For example, in development the host is configured
to "localhost" but you may be trying to access it from
"127.0.0.1". To fix this issue, you may either:
1. update [url: [host: ...]] to your actual host in the
config file for your current environment (recommended)
2. pass the :check_origin option when configuring your
endpoint or when configuring the transport in your
UserSocket module, explicitly outlining which origins
are allowed:
check_origin: ["https://example.com",
"//another.com:888", "//other.com"]
因此,您可以像以下方式重新配置主机:
[url: [host: "http://www.phoenix.hollyer.me.uk"]]
将 :check_origin 选项传递给端点配置或 UserSocket 模块:
check_origin: ["http://www.phoenix.hollyer.me.uk"]
然后尝试再次部署。希望对您有所帮助!
