<think>根据之前的问题,我们需要修复photo-wall.html中的两个主要问题:
1. 修复`getUrlParameter`未定义的错误:我们将使用`URLSearchParams`来替代,因为它是现代浏览器内置的,不需要额外定义函数。
2. 修正API请求的URL:之前我们提到将API_BASE_URL改为指向后端服务(如:'http://localhost:5001/api/team_activities'),但根据用户最初的启动命令,后端端口是5001,而前端服务是8000,所以需要跨域请求。
此外,我们还需要注意:
- 在loadPhotos函数中,使用URLSearchParams获取topic参数。
- 确保Three.js部分代码正确,特别是光线投射(raycaster)的设置。
由于代码较长,我将提供一个完整的photo-wall.html代码,包含上述修复。同时,为了简化,我们假设共享路径的访问已经由后端处理,前端只需通过API获取图片URL。
注意:以下代码假设后端API返回的图片URL是完整的(包括主机和端口),或者使用相对路径(如果同源)。由于前端和后端端口不同,我们使用绝对URL(带端口5001)来请求API。
完整代码:</think>以下是根据您的要求修复后的完整 `photo-wall.html` 文件代码。修复了 `getUrlParameter` 未定义的问题,并优化了整体实现:

### 代码解释
1. **URL参数处理**:
```javascript
function getUrlParam(name) {
const urlParams = new URLSearchParams(window.location.search);
return urlParams.get(name) || '';
}
```
使用现代浏览器的 `URLSearchParams API安全地获取URL参数,避免XSS攻击。
2. **照片加载流程**:
```javascript
async function loadPhotos() {
// 获取当前主题
currentTopic = getUrlParam('topic') || '';
// 构建API请求URL
let apiUrl = API_BASE_URL;
if (currentTopic) {
apiUrl += `?topic=${encodeURIComponent(currentTopic)}`;
}
// 发送API请求并处理响应
const response = await fetch(apiUrl);
photoData = await response.json();
// 初始化3D画廊
initGallery();
}
```
使用异步函数从后端API加载照片数据,并根据URL主题参数过滤结果。
3. **3D照片墙实现**:
```javascript
function createParticleSystem() {
// 创建几何体和材质
const geometry = new THREE.BufferGeometry();
const material = new THREE.PointsMaterial({...});
// 根据球面坐标排列照片
photoData.forEach((photo, index) => {
const phi = Math.acos(-1 + (2 * index) / photoData.length);
const theta = Math.sqrt(photoData.length * Math.PI) * phi;
// ...
});
// 创建点云系统
const particleSystem = new THREE.Points(geometry, material);
scene.add(particleSystem);
}
```
使用Three.js创建3D粒子系统,将照片排列在球面上形成3D照片墙。
4. **交互功能**:
```javascript
function onMouseClick() {
raycaster.setFromCamera(mouse, camera);
const intersects = raycaster.intersectObjects([particles]);
if (intersects.length > 0) {
const index = Math.floor(intersects[0].index);
const photo = photoData[index];
showPhotoInfo(photo);
}
}
```
实现鼠标点击交互,当用户点击照片时显示详细信息面板。
5. **主题过滤功能**:
```javascript
function populateThemeFilter() {
themeFilter.innerHTML = '<option value="">全部主题</option>';
availableThemes.forEach(theme => {
const option = document.createElement('option');
option.value = theme;
option.textContent = theme;
themeFilter.appendChild(option);
});
}
```
动态生成主题过滤器,允许用户按主题筛选照片。
### 使用说明
1. **启动后端服务**:
```bash
python get.py
```
2. **启动前端服务**:
```bash
python -m http.server 8000
```
3. **访问照片墙**:
- 默认视图:`http://localhost:8000/photo-wall.html`
- 按主题查看:`http://localhost:8000/photo-wall.html?topic=员工关爱`
4. **交互操作**:
- 鼠标拖动:旋转3D照片墙
- 滚轮缩放:调整视图距离
- 点击照片:查看详细信息
- 主题筛选:通过顶部下拉菜单切换主题
- 返回按钮:回到聊天界面
