-# Linux DO Connect
-
-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。
-
-目前系统已实现完整的 OAuth2 授权码（code）方式鉴权，但界面等配套功能还在持续完善中。让我们一起打造一个更完善的共享方案。
-
-## 基本介绍
-
-这是一套标准的 OAuth2 鉴权系统，可以让开发者共享论坛的用户基本信息。
-
-- 可获取字段：
-
-| 参数              | 说明                            |
-| ----------------- | ------------------------------- |
-| `id`              | 用户唯一标识（不可变）          |
-| `username`        | 论坛用户名                      |
-| `name`            | 论坛用户昵称（可变）            |
-| `avatar_template` | 用户头像模板URL（支持多种尺寸） |
-| `active`          | 账号活跃状态                    |
-| `trust_level`     | 信任等级（0-4）                 |
-| `silenced`        | 禁言状态                        |
-| `external_ids`    | 外部ID关联信息                  |
-| `api_key`         | API访问密钥                     |
-
-通过这些信息，公益网站/接口可以实现：
-
-1. 基于 `id` 的服务频率限制
-2. 基于 `trust_level` 的服务额度分配
-3. 基于用户信息的滥用举报机制
-

-## 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

-## 概述
-
-全面增强运维监控系统（Ops）的错误日志管理和告警静默功能，优化前端 UI 组件代码质量和用户体验。本次更新重构了核心服务层和数据访问层，提升系统可维护性和运维效率。
-
-## 主要改动
-
-### 1. 错误日志查询优化

-**功能特性：**
-- 新增 GetErrorLogByID 接口，支持按 ID 精确查询错误详情
-- 优化错误日志过滤逻辑，支持多维度筛选（平台、阶段、来源、所有者等）
-- 改进查询参数处理，简化代码结构
-- 增强错误分类和标准化处理
-- 支持错误解决状态追踪（resolved 字段）
-
-**技术实现：**
-- `ops_handler.go` - 新增单条错误日志查询接口
-- `ops_repo.go` - 优化数据查询和过滤条件构建
-- `ops_models.go` - 扩展错误日志数据模型
-- 前端 API 接口同步更新
-
-### 2. 告警静默功能
-
-**功能特性：**
-- 支持按规则、平台、分组、区域等维度静默告警
-- 可设置静默时长和原因说明
-- 静默记录可追溯，记录创建人和创建时间
-- 自动过期机制，避免永久静默
-
-**技术实现：**
-- `037_ops_alert_silences.sql` - 新增告警静默表
-- `ops_alerts.go` - 告警静默逻辑实现
-- `ops_alerts_handler.go` - 告警静默 API 接口
-- `OpsAlertEventsCard.vue` - 前端告警静默操作界面
-
-**数据库结构：**
-
-| 字段 | 类型 | 说明 |
-|------|------|------|
-| rule_id | BIGINT | 告警规则 ID |
-| platform | VARCHAR(64) | 平台标识 |
-| group_id | BIGINT | 分组 ID（可选） |
-| region | VARCHAR(64) | 区域（可选） |
-| until | TIMESTAMPTZ | 静默截止时间 |
-| reason | TEXT | 静默原因 |
-| created_by | BIGINT | 创建人 ID |
-
-### 3. 错误分类标准化

-**功能特性：**
-- 统一错误阶段分类（request|auth|routing|upstream|network|internal）
-- 规范错误归属分类（client|provider|platform）
-- 标准化错误来源分类（client_request|upstream_http|gateway）
-- 自动迁移历史数据到新分类体系
-
-**技术实现：**
-- `038_ops_errors_resolution_retry_results_and_standardize_classification.sql` - 分类标准化迁移
-- 自动映射历史遗留分类到新标准
-- 自动解决已恢复的上游错误（客户端状态码 < 400）
-
-### 4. Gateway 服务集成
