+# PRD — 预设配置与登录账号预设
+
+> **版本**: v1.0
+> **日期**: 2026-08-20
+> **状态**: 待实现
+> **关联 PRD**: `_PRD_接口预设功能.md`、`_PRD_性能测试模块需求文档.md`
+

+
+## 1. 背景与目标
+
+### 1.1 背景
+
+当前性能测试模块存在以下问题：
+
+1. **术语混淆**：当前菜单/页面称「接口预设」，但实际功能不仅是接口配置，还包括认证配置、捕获规则等，**「预设配置」** 更准确反映其作为「压测任务模板」的定位。
+2. **登录凭据与接口配置脱节**：接口预设（`api_presets`）只存了 `account_key`（超级管理员/管理员/普通用户），但实际的用户名密码是硬编码在 `performance_service.py` 的 `_DEFAULT_ACCOUNTS` 中的。用户新建任务时仍需手动填写登录用户名/密码，或使用默认值，无法复用预设中保存的凭据。
+3. **凭据无名称标识**：当前任务级的 `login_username`/`login_password` 字段没有名称标签，如果多个任务使用不同凭据，用户无法区分。
+
+### 1.2 目标
+
+1. **术语统一**：将「接口预设」更名为「预设配置」（菜单、页面、弹窗、API 路径注释等全部同步）
+2. **预设存储登录凭据**：每个预设配置中直接存储 `credential_name`（凭据名称，如"超级管理员"、"测试账号A"）、`login_username`、`login_password`
+3. **新建任务一键填充**：选择预设配置后，自动填充接口字段（Method/URL/Headers/Body）+ 登录凭据（用户名/密码），用户无需再手动填写
+4. **向后兼容**：已有预设自动获得默认凭据值；已有任务（无预设）不受影响
+
+---

+
+## 3. 详细需求
+
+### 3.1 术语重命名映射
+
+| 当前位置 | 旧名称 | 新名称 |
+|---------|--------|--------|
+| 侧边栏菜单 | 接口预设 | 预设配置 |
+| 路由 path | `presets` | 不变（URL 路径无需改，避免破坏书签） |
+| 路由 meta.title | 接口预设 | 预设配置 |
+| 列表页标题 | 接口预设列表 | 预设配置列表 |
+| 新建弹窗标题 | 新建接口预设 | 新建预设配置 |
+| 编辑弹窗标题 | 编辑接口预设 | 编辑预设配置 |
+| 任务表单标签 | 接口预设 | 预设配置 |
+| 提示文案 | 接口预设用于快速填充任务配置 | 预设配置用于快速填充任务配置 |
+| 后端 API 路径 | 不变（`/api/performance/presets`） | 不变 |
+| 后端模型/类名 | `ApiPreset` | 不变（类名不改，避免大面积重构） |
+| 后端注释/docstring | 接口预设 | 预设配置 |
+
+### 3.2 数据模型变更
+
+#### 3.2.1 ApiPreset 模型新增字段
+
+```python
+class ApiPreset(Base):
+    """预设配置数据库模型"""
+    __tablename__ = "api_presets"
+
+    # ... 现有字段不变 ...
+
+    # 新增：登录凭据配置
+    credential_name: Mapped[Optional[str]] = mapped_column(
+        String(100), nullable=True, default=None, comment="凭据名称，如'超级管理员'"
+    )
+    login_username: Mapped[Optional[str]] = mapped_column(
+        String(200), nullable=True, default=None, comment="自定义登录用户名，留空使用默认"
+    )
+    login_password: Mapped[Optional[str]] = mapped_column(
+        String(200), nullable=True, default=None, comment="自定义登录密码，留空使用默认"
+    )
+```
+
+`to_dict()` 中同步返回这三个字段。
+
+#### 3.2.2 数据库迁移
+
+```python
+# database.py _ensure_columns 追加：
+("api_presets", "credential_name", "VARCHAR(100) DEFAULT NULL"),
+("api_presets", "login_username", "VARCHAR(200) DEFAULT NULL"),
+("api_presets", "login_password", "VARCHAR(200) DEFAULT NULL"),
+```
+
+### 3.3 Schema 变更
+
+#### 3.3.1 ApiPresetCreate / ApiPresetUpdate 新增字段
+
+```python
+credential_name: Optional[str] = Field(None, description="凭据名称")
+login_username: Optional[str] = Field(None, description="登录用户名")
+login_password: Optional[str] = Field(None, description="登录密码")
+```
+
+#### 3.3.2 ApiPresetListItem 增加凭据名称
+
+列表项中增加 `credential_name` 字段，用于任务表单下拉和列表展示。
+
+### 3.4 前端变更
+
+#### 3.4.1 侧边栏菜单 + 路由
+
+- `App.vue`：`接口预设` → `预设配置`
+- `router/index.ts`：`meta.title` 改为 `预设配置`
+
+#### 3.4.2 预设配置列表页（ApiPresetList.vue）
+
+- 页面标题/提示文案：「接口预设」→「预设配置」
+- 列表列：新增「凭据名称」列（显示 credential_name，无则显示 `-`）
+- 新建/编辑弹窗标题：同步改名
+
+#### 3.4.3 预设配置编辑弹窗（ApiPresetDialog.vue）
+
+在「认证配置」区域（账号 select 下方）新增三个输入框：
+
+```
+┌─ 认证配置 ──────────────────────────────┐
+│ 需要登录认证 [switch]                     │
+│ 请求需要签名 [switch]                     │
+│ 账号 [select: superadmin/admin/user]      │
+│ ── 登录凭据（可选，留空使用默认值） ──    │
+│ 凭据名称 [input]  ← 如"超级管理员"        │
+│ 登录用户名 [input]                        │
+│ 登录密码 [password input]                 │
+└──────────────────────────────────────────┘
+```
+
+凭据名称、用户名、密码三个字段仅在 `authRequired=true` 时显示。
+
+#### 3.4.4 任务创建表单（TaskList.vue）
+
+**当前行为**：选择预设后只填充 Method/URL/Headers/Body/Auth/Sign/AccountKey，登录凭据仍需要手动填。
+
+**改造后行为**：选择预设后，额外自动填充：
+- `form.loginUsername` ← preset.login_username
+- `form.loginPassword` ← preset.login_password
+- 摘要卡片增加凭据名称行：`凭据：超级管理员`
+
+**摘要卡片示例**：
+```
+┌─ 预设配置: 新建会议V3 ───────────────────────┐
+│ PUT https://192.168.5.44/meetingV3/api/message/book │
+│ 需要登录（超级管理员） · 需要签名                 │
+└────────────────────────────────────────────────┘
+```
+
+**编辑回填**：如果任务有 `preset_id`，从预设加载凭据名称并显示。
+
+### 3.5 后端处理逻辑
+
+#### 3.5.1 创建预设时凭据字段处理
+
+新建/编辑预设时，凭据名称/用户名/密码为可选字段，留空时存 `null`。
+
+#### 3.5.2 创建任务时预设继承（无需改动）
+
+当前 `performance_service.py` 的 `create_task()` 中，预设继承已处理 `account_key`：
+```python
+data["account_key"] = data.get("account_key") or preset.account_key
+```
+
+新增的 `login_username`/`login_password` 同理也会被任务数据覆盖或继承。但需要注意：**当前逻辑中 `login_username`/`login_password` 不是从预设继承的**，需要补充：
+
+```python
+# 从预设继承登录凭据
+if not data.get("login_username"):
+    data["login_username"] = getattr(preset, "login_username", None)
+if not data.get("login_password"):
+    data["login_password"] = getattr(preset, "login_password", None)
+```
+
+#### 3.5.3 执行时凭据使用（无需改动）
+
+`_build_client_config()` 已支持从 `task_dict` 读取 `login_username`/`login_password`，预设继承后自动生效，无需额外改动。
+
+---
+
+## 4. 非功能需求
+
+### 4.1 兼容性
+
+- 已有预设（无 `credential_name`/`login_username`/`login_password` 字段）完全不受影响，默认值为 `null`
+- 已有任务（无 `preset_id`）不受影响，创建/编辑/执行逻辑不变
+- 预设凭据更新后，已创建的任务不受影响（任务存储的是当时的值，不是引用）
+
+### 4.2 约束
+
+- 凭据名称仅用作显示标签，不参与唯一性校验（不同预设可用相同凭据名称）
+- 登录密码以明文存库（`api_presets.login_password`），内网平台可接受
+- 预设凭据字段留空时，执行时回退 `_DEFAULT_ACCOUNTS` 默认值
+
+---
+
+## 5. 应用场景示例
+
+### 5.1 场景一：创建含凭据的预设配置
+
+1. 运维在预设配置页面新建「新建会议V3」：
+   - 方法：PUT，URL：`https://192.168.5.44/meetingV3/api/message/book`
+   - 需要登录 + 需要签名
+   - 凭据名称：`超级管理员`，用户名：`admin@xty`，密码：`Ubains@13579`
+
+2. 测试同学创建压测任务：
+   - 选择预设：「新建会议V3」→ 自动填充所有接口字段 + 登录凭据
+   - 摘要卡片显示：`需要登录（超级管理员）`
+   - 设置并发数：10，时长：60s → 执行成功
+
+### 5.2 场景二：使用默认凭据的预设
+
+1. 运维新建预设「查询接口」：
+   - 方法：GET，URL：`https://192.168.5.44/platform/api/xxx`
+   - 需要登录，但凭据名称/用户名/密码留空
+
+2. 测试同学创建任务 → 选择该预设 → 登录凭据为空 → 执行时使用默认账号（`admin@xty / Ubains@13579`）

+
+---
+
+## Phase 1: 后端模型 + Schema（2 文件）
+
+### 1.1 models/api_preset.py
+
+在 `ApiPreset` 类中新增三个字段（放在 `account_key` 字段之后、`capture_rules` 之前）：
+
+```python
+# 登录凭据配置
+credential_name: Mapped[Optional[str]] = mapped_column(
+    String(100), nullable=True, default=None, comment="凭据名称，如'超级管理员'"
+)
+login_username: Mapped[Optional[str]] = mapped_column(
+    String(200), nullable=True, default=None, comment="自定义登录用户名，留空使用默认"
+)
+login_password: Mapped[Optional[str]] = mapped_column(
+    String(200), nullable=True, default=None, comment="自定义登录密码，留空使用默认"
+)
+```
+
+`to_dict()` 方法中新增返回：
+
+```python
+"credential_name": self.credential_name,
+"login_username": self.login_username,
+"login_password": self.login_password,
+```
+
+### 1.2 schemas/api_preset.py
+
+**ApiPresetCreate** — 新增三个可选字段：
+
+```python
+credential_name: Optional[str] = Field(None, description="凭据名称，如'超级管理员'")
+login_username: Optional[str] = Field(None, description="自定义登录用户名，留空使用默认")
+login_password: Optional[str] = Field(None, description="自定义登录密码，留空使用默认")
+```
+
+**ApiPresetUpdate** — 同上：
+
+```python
+credential_name: Optional[str] = Field(None, description="凭据名称")
+login_username: Optional[str] = Field(None, description="自定义登录用户名")
+login_password: Optional[str] = Field(None, description="自定义登录密码")
+```
+
+**ApiPresetResponse** — 新增返回：
+
+```python
+credential_name: Optional[str] = None
+login_username: Optional[str] = None
+login_password: Optional[str] = None
+```
+
+**ApiPresetListItem** — 列表项仅需返回凭据名称（用于下拉和列表展示）：
+
+```python
+credential_name: Optional[str] = None
+```
+
+### 1.3 数据库迁移
+
+在 `database.py` 的 `_ensure_columns()` 方法中追加：
+
+```python
+# 预设配置：登录凭据名称/用户名/密码（旧库升级）
+("api_presets", "credential_name", "VARCHAR(100) DEFAULT NULL"),
+("api_presets", "login_username", "VARCHAR(200) DEFAULT NULL"),
+("api_presets", "login_password", "VARCHAR(200) DEFAULT NULL"),
+```
+
+---
+
+## Phase 2: 后端 Service 预设继承补充（1 文件）
+
+### 2.1 services/performance_service.py
+
+在 `create_task()` 方法中，预设继承块（`if data.get("preset_id")`）内，补充 login_username/login_password 的继承逻辑。
+
+**当前代码**（约第 190-240 行）：
+
+```python
+if data.get("preset_id"):
+    preset = await self.db.get(ApiPreset, data["preset_id"])
+    if not preset:
+        raise HTTPException(status_code=404, detail="预设不存在")
+    # 预设字段作为默认值，任务显式传入的字段覆盖
+    if not data.get("method"):
+        data["method"] = preset.method
+    if not data.get("target_url"):
+        data["target_url"] = preset.target_url
+    # ... 其他字段 ...
+    if not data.get("account_key"):
+        data["account_key"] = preset.account_key
+    # ⬇️ 新增：从预设继承登录凭据
+    if not data.get("login_username"):
+        data["login_username"] = preset.login_username
+    if not data.get("login_password"):
+        data["login_password"] = preset.login_password
+```
+
+**注意**：`login_username`/`login_password` 在 `PerformanceTask` 模型中已存在（第 111-114 行），无需再改模型。
+
+---
+
+## Phase 3: 前端文案更新 + 菜单/路由（2 文件）
+
+### 3.1 App.vue
+
+搜索 `接口预设` 字符串，改为 `预设配置`。
+
+```html
+<!-- 第 90 行附近 -->
+<el-menu-item index="/performance/presets">预设配置</el-menu-item>
+```
+
+侧边栏面板的 `presets` 映射也要改：
+
+```typescript
+// 第 286 行附近
+presets: '预设配置',
+```
+
+### 3.2 router/index.ts
+
+```typescript
+// 第 188 行附近
+meta: { title: '预设配置' }
+```
+
+---
+
+## Phase 4: 前端预设配置列表页（1 文件）
+
+### 4.1 ApiPresetList.vue
+
+**文案变更**：
+- 提示文案：`接口预设用于快速填充任务配置` → `预设配置用于快速填充任务配置`
+
+**新增列**：在「方法」列之后、「目标 URL」列之前插入凭据名称列：
+
+```html
+<el-table-column prop="credentialName" label="凭据名称" width="150" show-overflow-tooltip>
+  <template #default="{ row }">
+    <span>{{ row.credentialName || '-' }}</span>
+  </template>
+</el-table-column>
+```
+
+---
+
+## Phase 5: 前端预设编辑弹窗（1 文件）
+
+### 5.1 ApiPresetDialog.vue
+
+**弹窗标题**：`新建接口预设` → `新建预设配置`，`编辑接口预设` → `编辑预设配置`
+
+**新增表单字段**：在「账号」select 下方增加凭据配置区域（仅 `authRequired=true` 时显示）：
+
+```html
+<!-- 认证配置区域末尾，accountKey 之后 -->
+<el-divider v-if="form.authRequired" style="margin: 8px 0" />
+<template v-if="form.authRequired">
+  <div class="credential-section-label">登录凭据（可选，留空使用默认值）</div>
+  <el-row :gutter="16">
+    <el-col :span="8">
+      <el-form-item label="凭据名称">
+        <el-input v-model="form.credentialName" placeholder="如：超级管理员" clearable />
+      </el-form-item>
+    </el-col>
+    <el-col :span="8">
+      <el-form-item label="登录用户名">
+        <el-input v-model="form.loginUsername" placeholder="留空使用默认" clearable />
+      </el-form-item>
+    </el-col>
+    <el-col :span="8">
+      <el-form-item label="登录密码">
+        <el-input v-model="form.loginPassword" type="password" show-password placeholder="留空使用默认" clearable />
+      </el-form-item>
+    </el-col>
+  </el-row>
+</template>
+```
+
+**表单数据模型 (PresetForm)** 新增字段：
+
+```typescript
+interface PresetForm {
+  // ... 现有字段 ...
+  credentialName: string
+  loginUsername: string
+  loginPassword: string
+}
+```
+
+**defaultForm()** 新增默认值：
+
+```typescript
+const defaultForm = (): PresetForm => ({
+  // ... 现有 ...
+  credentialName: '',
+  loginUsername: '',
+  loginPassword: '',
+})
+```
+
+**initForm()** — 编辑时回填：
+
+```typescript
+form.credentialName = p.credentialName || ''
+form.loginUsername = p.loginUsername || ''
+form.loginPassword = p.loginPassword || ''
+```
+
+**handleSave()** — 提交数据补发：
+
+```typescript
+const data: any = {
+  // ... 现有 ...
+  credentialName: form.credentialName || null,
+  loginUsername: form.loginUsername || null,
+  loginPassword: form.loginPassword || null,
+}
+```
+
+---
+
+## Phase 6: 前端任务列表预设填充（1 文件）
+
+### 6.1 TaskList.vue
+
+**onPresetChange()** — 选择预设后填充登录凭据：
+
+在 `onPresetChange` 函数的赋值段末尾（`form.accountKey` 之后）补充：
+
+```typescript
+// 填充登录凭据
+form.loginUsername = preset.loginUsername || ''
+form.loginPassword = preset.loginPassword || ''
+```
+
+**预设摘要卡片** — 显示凭据名称：
+
+在认证行中，当前显示 `需要登录（超级管理员）` 的逻辑已通过 `accountKeyLabel(preset.accountKey)` 显示。需改为显示预设的 `credentialName`：
+
+```html
+<div>
+  <strong>认证：</strong>

+#### 0. 指标体系增强（10项新指标）✅（已完成，未部署）
+
+**用户需求**：对标 JMeter 的市场标准，增强性能测试指标体系，提供更全面的分析维度。
+
+**参考标准**：JMeter 默认指标 + 行业主流（P95/标准差/Apdex/吞吐量/错误分类等）
+
+**本次新增 10 项指标**：
+
+| # | 指标 | 含义 | 采集方式 |
+|---|------|------|---------|
+| 1 | **P95** | 95% 请求响应时间阈值 | 线性插值百分位数 |
+| 2 | **标准差 (Std Dev)** | 响应时间离散程度 | 总体标准差 `sqrt(sum((x-mean)²)/n)` |

+- 前端 `npm run build` → **built in 30.21s**，vue-tsc 类型检查无错误 ✅（修复了 ApiPreset 类型缺少 `credentialName/loginUsername/loginPassword` 的 TS 错误）
+- **尚未部署 5.60 服务器**
+
+**⚠️ 关键算法**：
+- **P95 线性插值**：`sorted_data[f] + (sorted_data[c] - sorted_data[f]) * (k - f)`，其中 `k = p/100 * (n-1)`，`f=floor(k)`，`c=ceil(k)`
+- **总体标准差**：`math.sqrt(sum((x-mean)²)/n)`（分母为 n，非 n-1）
+- **Apdex**：T=500ms 固定，满意 ≤T，容忍 ≤4T，超出 >4T；公式 `(satisfied + tolerating/2) / total`
+- **错误分类优先级**：`error_type` 字段 > HTTP 状态码 → 错误消息中的关键字

+- 前端 dist 全量（已构建通过）
+- 部署步骤：scp 后端文件 → 清理 *.pyc → `docker restart plat-auto-test-app` → scp 前端 dist → 浏览器 Ctrl+F5 强刷
+- 部署后验证：`GET /api/performance/tasks/{旧任务ID}/report` 返回新指标字段（p95/std_dev/apdex 等）
+
+### 集成验证（待完成）
+
+- 运行一次短压测（concurrency=1, duration=5s），验证:
+  - 报告 API 返回所有新指标字段 ✅
+  - WebSocket 快照含新字段（std_dev/latency_avg/connect_time_avg/sentBytes/receivedBytes/peakTps）
+  - 前端报告面板显示 16 个指标卡片 + 新图表
+  - 错误分类（可手动构造 4xx/5xx 场景验证）
+
+### P0 - 按请求序号错开时间段（并发压测预约类接口的关键）
