AI Summary: 本文介绍了DepyDocs租户域名绑定的必要性及两种绑定方式：基于Nginx反向代理和基于CloudFlare Workers。强调从2023年12月10日起，未绑定域名的租户将不再获得新功能支持，自2024年4月起不再提供免费域名绑定，已绑定域名的租户需强制解绑。Nginx配置需包含SSL证书，CloudFlare的设置则需在DNS服务器中修改。文中还提供了JavaScript代码示例，用于CloudFlare Workers的设置，涵盖了请求转发、阻止特定地区和IP访问、文本替换等功能。 --- (From Model:gpt-4o-mini-2024-07-18)

## change list

(2023-12-10起，新功能**不再**对未绑定域名使用的租户进行兼容）
(2024-04起不再提供免费域名绑定,已绑定域名租户强制解绑,请及时修改租户额外配置)
(2024-09起**灰度删除**对无域名绑定的功能兼容代码)

## 介绍

DepyDocs租户需要使用域名绑定的功能，供用户个性化使用服务，本人提供以下两种绑定方式。

1、请务必在后台绑定域名，否则会导致资源加载错误
2、请务必使用配置了SSL证书的域名，否则会导致图床图片加载异常、Websocket无法连接

### 基于Nginx反向代理（需要服务器）

域名解析服务器后使用nginx反向代理，配置文件如下，注意修改租户id。

```bash

server {
    listen 80;
    listen 443 ssl;
    server_name wiki.rce.ink;
    index index.html;

if ($server_port !~ 443){
        rewrite ^(/.*)$ https://$host$1 permanent;
    }
	
    ssl_certificate /ssl/wiki.rce.ink/fullchain1.pem;
    ssl_certificate_key /ssl/wiki.rce.ink/privkey1.pem;

location / {
	
        proxy_pass https://proxy.rce.ink/index/tenant/租户id/;
        proxy_set_header Host proxy.rce.ink;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
		
    }

}
```

### 基于CloudFlare Workers（无需服务器）

修改DNS服务器为cloudflare提供的DNS服务器。

点击部署后，重新进入编辑界面，替换代码为下面的代码。
```javascript
// 目标网站
const upstream = 'rce.ink'

// 目标网站路径
const upstream_path = '/index/tenant/租户id/'

// 打算为使用移动设备的用户检索的网站.
const upstream_mobile = 'rce.ink'

// 您希望暂停服务的国家和地区
const blocked_region = []

// 要阻止其使用服务的IP地址
const blocked_ip_address = ['0.0.0.0', '127.0.0.1']

// 上游地址是否使用HTTPS协议
const https = true

// 是否禁用缓存
const disable_cache = false

// 替换文本
//格式：  '被替换':'替换'
//注意js结束的的逗号
const replace_dict = {
    // 'www.google.com':'yourworkername.yourusername.workers.dev'
