+OAuth（Open Authorization）是一个开放的网络授权标准，目前最新版本为 OAuth 2.0。我们日常使用的第三方登录（如 Google 账号登录）就采用了该标准。OAuth 允许用户授权第三方应用访问存储在其他服务提供商（如 Google）上的信息，无需在不同平台上重复填写注册信息。用户授权后，平台可以直接访问用户的账户信息进行身份验证，而用户无需向第三方应用提供密码。

+
+## 使用说明
+
+### 授权流程
+
+1. 用户点击应用中的’使用 Linux Do 登录’按钮
+2. 系统将用户重定向至 Linux Do 的授权页面
+3. 用户完成授权后，系统自动重定向回应用并携带授权码
+4. 应用使用授权码获取访问令牌
+5. 使用访问令牌获取用户信息
+
+### 安全建议
+
+- 切勿在前端代码中暴露 Client Secret
+- 对所有用户输入数据进行严格验证
+- 确保使用 HTTPS 协议传输数据
+- 定期更新并妥善保管 Client Secret

+- `turnstile.required` to require Turnstile in release mode
+
+**⚠️ Security Warning: HTTP URL Configuration**
+
+When `security.url_allowlist.enabled=false`, the system performs minimal URL validation by default, **rejecting HTTP URLs** and only allowing HTTPS. To allow HTTP URLs (e.g., for development or internal testing), you must explicitly set:
+
+```yaml
+security:
+  url_allowlist:
+    enabled: false                # Disable allowlist checks
+    allow_insecure_http: true     # Allow HTTP URLs (⚠️ INSECURE)
+```
+
+**Or via environment variable:**
+
+```bash
+SECURITY_URL_ALLOWLIST_ENABLED=false
+SECURITY_URL_ALLOWLIST_ALLOW_INSECURE_HTTP=true
+```
+
+**Risks of allowing HTTP:**
+- API keys and data transmitted in **plaintext** (vulnerable to interception)
+- Susceptible to **man-in-the-middle (MITM) attacks**
+- **NOT suitable for production** environments
+
+**When to use HTTP:**
+- ✅ Development/testing with local servers (http://localhost)
+- ✅ Internal networks with trusted endpoints
+- ✅ Testing account connectivity before obtaining HTTPS
+- ❌ Production environments (use HTTPS only)
+
+**Example error without this setting:**
+```
+Invalid base URL: invalid url scheme: http
+```
+
+If you disable URL validation or response header filtering, harden your network layer:
+- Enforce an egress allowlist for upstream domains/IPs
+- Block private/loopback/link-local ranges
+- Enforce TLS-only outbound traffic
+- Strip sensitive upstream response headers at the proxy
