## Reverse Proxy
Gitea supports Reverse Proxy Header authentication, it will read headers as a trusted login user name or user email address. This hasn't been enabled by default, you can enable it with
```ini
[service]
ENABLE_REVERSE_PROXY_AUTHENTICATION = true
```
The default login user name is in the `X-WEBAUTH-USER` header, you can change it via changing `REVERSE_PROXY_AUTHENTICATION_USER` in app.ini. If the user doesn't exist, you can enable automatic registration with `ENABLE_REVERSE_PROXY_AUTO_REGISTRATION=true`.
The default login user email is `X-WEBAUTH-EMAIL`, you can change it via changing `REVERSE_PROXY_AUTHENTICATION_EMAIL` in app.ini, this could also be disabled with `ENABLE_REVERSE_PROXY_EMAIL`
If set `ENABLE_REVERSE_PROXY_FULL_NAME=true`, a user full name expected in `X-WEBAUTH-FULLNAME` will be assigned to the user when auto creating the user. You can also change the header name with `REVERSE_PROXY_AUTHENTICATION_FULL_NAME`.
You can also limit the reverse proxy's IP address range with `REVERSE_PROXY_TRUSTED_PROXIES` which default value is `127.0.0.0/8,::1/128`. By `REVERSE_PROXY_LIMIT`, you can limit trusted proxies level.
Notice: Reverse Proxy Auth doesn't support the API. You still need an access token or basic auth to make API requests.

## TBD ## 反向代理认证
Gitea 支持通过读取反向代理传递的 HTTP 头中的登录名或者 email 地址来支持反向代理来认证。默认是不启用的,你可以用以下配置启用。
```ini
[service]
ENABLE_REVERSE_PROXY_AUTHENTICATION = true
```
默认的登录用户名的 HTTP 头是 `X-WEBAUTH-USER`,你可以通过修改 `REVERSE_PROXY_AUTHENTICATION_USER` 来变更它。如果用户不存在,可以自动创建用户,当然你需要修改 `ENABLE_REVERSE_PROXY_AUTO_REGISTRATION=true` 来启用它。
默认的登录用户 Email 的 HTTP 头是 `X-WEBAUTH-EMAIL`,你可以通过修改 `REVERSE_PROXY_AUTHENTICATION_EMAIL` 来变更它。如果用户不存在,可以自动创建用户,当然你需要修改 `ENABLE_REVERSE_PROXY_AUTO_REGISTRATION=true` 来启用它。你也可以通过修改 `ENABLE_REVERSE_PROXY_EMAIL` 来启用或停用这个 HTTP 头。
如果设置了 `ENABLE_REVERSE_PROXY_FULL_NAME=true`,则用户的全名会从 `X-WEBAUTH-FULLNAME` 读取,这样在自动创建用户时将使用这个字段作为用户全名,你也可以通过修改 `REVERSE_PROXY_AUTHENTICATION_FULL_NAME` 来变更 HTTP 头。
你也可以通过修改 `REVERSE_PROXY_TRUSTED_PROXIES` 来设置反向代理的IP地址范围加强安全性默认值是 `127.0.0.0/8,::1/128`。 通过 `REVERSE_PROXY_LIMIT` 可以设置最多信任几级反向代理。
注意:反向代理认证不支持认证 APIAPI 仍旧需要用 access token 来进行认证。
