微信小程序需要使用https與wss能才進行連接，雖然開發(fā)模式下可以使用http與ws，但發(fā)布的時候還是需要安全協(xié)議,網(wǎng)上的各種配置是超多超復雜的，這里已經(jīng)對nginx指定版本進行最簡單的配置，可用。 

使用教程

nginx版本

1. $ nginx -v
2. nginx version: nginx/1.12.2

系統(tǒng)Centos7

1. $ uname -r
2. 4.14.11-1.el7.elrepo.x86_64

cat /etc/nginx/conf.d/test.conf

1. server {
2. listen 80;
3. server_name test.dounine.com;
4. return 301 https://$host$request_uri;
5. }
6.  
7. server {
8. listen 443;
9. server_name test.dounine.com;
10. ssl on;
11. ssl_certificate /etc/nginx/ssls/test.xxxx.pem;
12. ssl_certificate_key /etc/nginx/ssls/test.xxxx.key;
13.  
14. location / {
15. client_max_body_size 100m;
16. proxy_pass http://localhost:7777;
17. proxy_set_header Host $host;
18. proxy_set_header X-Real-IP $remote_addr;
19. proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
20. proxy_set_header Upgrade $http_upgrade;
21. proxy_set_header Connection "Upgrade";
22. }
23.  
24. }

微信小程序代碼

1. wx.connectSocket({
2. url: 'wss://test.dounine.com/ws'
3. });
4. wx.onSocketOpen(function(res) {
5. console.info('websocket連接成功');
6. });
7. wx.onSocketClose(function(res) {
8. console.log('WebSocket 已關(guān)閉！')
9. });
10. wx.onSocketError(function(res){
11. console.log('WebSocket連接打開失敗，請檢查！')
12. });
13. wx.onSocketMessage(function(res) {
14. console.log('收到服務(wù)器內(nèi)容：' + res.data)
15. })
