| | | ## wss or ws protocol for ws_server_online
|
|---|
| | | 1) wss: browser microphone data --> html5 demo server --> js wss api --> wss asr online srv #for certificate generation just look back
|
|---|
| | |
|
|---|
| | | 2) ws: browser microphone data --> html5 demo server --> js wss api --> nginx wss server --> ws asr online srv
|
|---|
| | |
|
|---|
| | | ## 1.html5 demo start
|
|---|
| | | ### ssl certificate is required
|
|---|
| | | ## Steps
|
|---|
| | | ### Html5 demo
|
|---|
| | |
|
|---|
| | | ```shell
|
|---|
| | | usage: h5Server.py [-h] [--host HOST] [--port PORT] [--certfile CERTFILE]
|
|---|
| | | [--keyfile KEYFILE]
|
|---|
| | | python h5Server.py --port 1337
|
|---|
| | | usage: h5Server.py [-h] [--host HOST] [--port PORT] [--certfile CERTFILE] [--keyfile KEYFILE]
|
|---|
| | | ```
|
|---|
| | | ## 2.asr online srv start
|
|---|
| | | [detail for online asr](https://github.com/alibaba-damo-academy/FunASR/tree/main/funasr/runtime/python/websocket)
|
|---|
| | | Online asr provides wss or ws way. if started in ws way, nginx is required for relay.
|
|---|
| | | ### wss way, ssl certificate is required
|
|---|
| | | `e.g.`
|
|---|
| | | ```shell
|
|---|
| | | python ws_server_online.py --certfile server.crt --keyfile server.key --port 5921
|
|---|
| | | python h5Server.py --host 0.0.0.0 --port 1337 |
|---|
| | | ```
|
|---|
| | | ### ws way
|
|---|
| | | ### asr service
|
|---|
| | | [detail for asr]((../python/websocket))
|
|---|
| | |
|
|---|
| | | `Tips:` asr service and html5 service should be deployed on the same device.
|
|---|
| | | ```shell
|
|---|
| | | python ws_server_online.py --port 5921
|
|---|
| | | cd ../python/websocket
|
|---|
| | | python ws_server_online.py --port 1095
|
|---|
| | | ```
|
|---|
| | |
|
|---|
| | | ## 3.open browser to access html5 demo
|
|---|
| | | https://youraddress:port/static/index.html
|
|---|
| | |
|
|---|
| | | ## 4.modify asr address in html according to your environment
|
|---|
| | | ### open browser to access html5 demo
|
|---|
| | | ```shell
|
|---|
| | | https://127.0.0.1:1337/static/index.html
|
|---|
| | | # https://30.220.136.139:1337/static/index.html
|
|---|
| | | ```
|
|---|
| | |
|
|---|
| | | ### modify asr address in html according to your environment
|
|---|
| | | asr address in index.html must be wss
|
|---|
| | |
|
|---|
| | |
|
|---|
| | |
|
|---|
| | | ## certificate generation by yourself
|
|---|
| | | generated certificate may not suitable for all browsers due to security concerns. you'd better buy or download an authenticated ssl certificate from authorized agency.
|
|---|
| | |
|
|---|
| | | ```shell
|
|---|
| | | ### 1) Generate a private key
|
|---|
| | | openssl genrsa -des3 -out server.key 1024
|
|---|
| | | |
|---|
| | | ### 2) Generate a csr file
|
|---|
| | | openssl req -new -key server.key -out server.csr
|
|---|
| | | |
|---|
| | | ### 3) Remove pass
|
|---|
| | | cp server.key server.key.org |
|---|
| | | openssl rsa -in server.key.org -out server.key
|
|---|
| | | |
|---|
| | | ### 4) Generated a crt file, valid for 1 year
|
|---|
| | | openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
|
|---|
| | | ```
|
|---|
| | |
|
|---|
| | | ## nginx configuration (you can skip it if you known)
|
|---|
| | | https and wss protocol are required by browsers when want to open microphone and websocket. |
|---|
| | | if [online asr](https://github.com/alibaba-damo-academy/FunASR/tree/main/funasr/runtime/python/websocket) run in ws way, you should use nginx to convert wss to ws.
|
|---|
| | | ### nginx wss->ws configuration example
|
|---|
| | | ```shell
|
|---|
| | | events { [0/1548]
|
|---|
| | | worker_connections 1024;
|
|---|
| | | accept_mutex on;
|
|---|
| | | }
|
|---|
| | | http {
|
|---|
| | | error_log error.log;
|
|---|
| | | access_log access.log;
|
|---|
| | | server {
|
|---|
| | |
|
|---|
| | | listen 5921 ssl http2; # nginx listen port for wss
|
|---|
| | | server_name www.test.com;
|
|---|
| | |
|
|---|
| | | ssl_certificate /funasr/server.crt;
|
|---|
| | | ssl_certificate_key /funasr/server.key;
|
|---|
| | | ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
|
|---|
| | | ssl_ciphers HIGH:!aNULL:!MD5;
|
|---|
| | |
|
|---|
| | | location /wss/ {
|
|---|
| | |
|
|---|
| | |
|
|---|
| | | proxy_pass http://127.0.0.1:1111/; # asr online model ws address and port
|
|---|
| | | proxy_http_version 1.1;
|
|---|
| | | proxy_set_header Upgrade $http_upgrade;
|
|---|
| | | proxy_set_header Connection "upgrade";
|
|---|
| | | proxy_read_timeout 600s;
|
|---|
| | |
|
|---|
| | | }
|
|---|
| | | }
|
