1、docker 安装 onlyoffice 端口号注意 8080

docker run -it -d -p 8080:80 -e JWT_ENABLED=false -e USE_UNAUTHORIZED_STORAGE=true -e ONLYOFFICE_HTTPS_HSTS_ENABLED=false --restart=always --name onlyoffice onlyoffice/documentserver

#将配置文件copy出来
docker cp onlyoffice:/etc/onlyoffice/documentserver/default.json ./
#打开修改
nano default.json
"request-filtering-agent" : {
        "allowPrivateIPAddress": true,
        "allowMetaIPAddress": true
},
#复制copy回去
docker cp ./default.json onlyoffice:/etc/onlyoffice/documentserver/default.json
#重启容器
docker restart onlyoffice

2、增加 view.html 文件

mkdir  /root/onlyoffice
cd /root/onlyoffice
nano view.html

src 的值，要填写自己的主机 IP，端口号就是刚才创建的 onlyoffice 容器暴露的端口

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>OnlyOffice Viewer</title>
</head>

<body>
    <div id="placeholder"></div>
    <script type="text/javascript" src="http://主机IP:8080/web-apps/apps/api/documents/api.js"></script>
    <script>
        function getQueryParamValue(name) {
            const searchParams = new URLSearchParams(window.location.search);
            return searchParams.get(name);
        }

        const url = decodeURIComponent(getQueryParamValue("src"));
        const fileName = url.substring(url.lastIndexOf('/') + 1, url.lastIndexOf('?') != -1 ? url.lastIndexOf('?') : url.length);
        const fileExtension = fileName.split('.').pop();
        const docEditor = new DocsAPI.DocEditor("placeholder", {
            "document": {
                "fileType": fileExtension,
                "permissions": {
                    "edit": false,
                    "comment": true,
                    "download": true,
                    "print": true,
                    "fillForms": true,
                },
                "title": fileName,
                "url": url,
            },
            "editorConfig": {
                "lang": "zh-CN",
                "mode": "view",
            },
            "height": "1080px",
            "type": "desktop",
        });
    </script>
</body>
</html>

3、安装 nginx，修改配置

apt install nginx
nano  /etc/nginx/conf.d/onlyoffice.conf

server {
listen 8081;
server_name localhost;
location / {
   root /root/onlyoffice;  #这里修改为自己的view.html的目录
   index index.html index.htm;
   proxy_redirect off;
   proxy_set_header Host $host;
   proxy_set_header X-Forwarded-Proto $scheme;
   proxy_set_header X-Real-IP $remote_addr;
   proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
   proxy_set_header Upgrade-Insecure-Requests 1;
   proxy_set_header X-Forwarded-Proto https;
   }
}

systemctl restart nginx

4、alist 预览配置增加

“onlyoffice”:”http:// 主机 IP:8081/view.html?src=$e_url”
