# 单图上传功能说明
## 功能概述
本项目提供了完整的单图上传功能，支持选择图片、上传到七牛云、返回图片URL。
## 文件结构
```
├── api/upload.js # 上传相关API
├── pages/image-upload/ # 上传页面
│ └── image-upload.vue
├── pages/image-upload-demo/ # 演示页面
│ └── image-upload-demo.vue
└── examples/ # 使用示例
└── single-image-upload-usage.vue
```
## 核心功能
### 1. API接口 (`api/upload.js`)
#### 获取七牛云上传Token
```javascript
import { getQiniuUploadToken } from '@/api/upload.js'
const res = await getQiniuUploadToken()
if (res.code === 200) {
const token = res.data?.token || res.data?.uploadToken || res.token || res.data
}
```
#### 上传图片到七牛云
```javascript
import { uploadToQiniu } from '@/api/upload.js'
const result = await uploadToQiniu(filePath, token, key)
const imageUrl = `https://api.ccttiot.com/${result.key}`
```
### 2. 上传页面 (`pages/image-upload/image-upload.vue`)
完整的图片上传页面，包含：
- 图片选择功能
- 预览功能
- 上传进度显示
- 错误处理
- 结果展示
## 使用方法
### 方法一：跳转到上传页面
```javascript
// 跳转到上传页面
uni.navigateTo({
url: '/pages/image-upload/image-upload'
})
// 监听上传成功事件
uni.$on('image-upload-success', (imageUrl) => {
console.log('上传成功:', imageUrl)
})
```
### 方法二：内嵌上传功能
```javascript
import { getQiniuUploadToken, uploadToQiniu } from '@/api/upload.js'
export default {
data() {
return {
selectedImage: '',
qiniuToken: '',
uploading: false
}
},
methods: {
// 选择图片
chooseImage() {
uni.chooseImage({
count: 1,
success: (res) => {
this.selectedImage = res.tempFilePaths[0]
}
})
},
// 上传图片
async uploadImage() {
if (!this.selectedImage) return
this.uploading = true
try {
// 获取token
if (!this.qiniuToken) {
const res = await getQiniuUploadToken()
this.qiniuToken = res.data?.token || res.data?.uploadToken || res.token || res.data
}
// 生成文件名
const key = `uploads/${Date.now()}_${Math.random().toString(36).slice(2)}.jpg`
// 上传
const result = await uploadToQiniu(this.selectedImage, this.qiniuToken, key)
const imageUrl = `https://api.ccttiot.com/${result.key}`
console.log('上传成功:', imageUrl)
} catch (error) {
console.error('上传失败:', error)
} finally {
this.uploading = false
}
}
}
}
```
## 页面配置
确保在 `pages.json` 中注册了相关页面：
```json
{
"pages": [
{
"path": "pages/image-upload/image-upload",
"style": {
"navigationBarTitleText": "图片上传",
"navigationStyle": "custom"
}
},
{
"path": "pages/image-upload-demo/image-upload-demo",
"style": {
"navigationBarTitleText": "图片上传演示",
"navigationStyle": "custom"
}
}
]
}
```
## 功能特点
### ✅ 已实现功能
- [x] 图片选择和预览
- [x] 七牛云上传
- [x] 上传进度显示
- [x] 错误处理和提示
- [x] 结果URL展示
- [x] URL复制功能
- [x] 多种使用方式
- [x] 完整的示例代码
### 🔧 技术特性
- 支持相册和相机选择
- 自动获取七牛云上传Token
- 智能Token字段解析
- 唯一文件名生成
- 完整的错误处理
- 响应式UI设计
## 注意事项
1. **Token获取**：确保后端API `/common/qiniu/uploadInfo` 正常工作
2. **域名配置**：七牛云上传域名已配置为 `https://up-z2.qiniup.com`
3. **图片域名**：图片访问域名配置为 `https://api.ccttiot.com`
4. **文件格式**：支持 JPG、PNG 等常见图片格式
5. **文件大小**：建议图片大小不超过 5MB
## 调试
如果遇到上传问题，可以：
1. 检查控制台日志
2. 验证Token获取是否成功
3. 确认网络连接正常
4. 检查七牛云配置是否正确
## 示例页面
访问以下页面查看完整示例：
- `/pages/image-upload-demo/image-upload-demo` - 演示页面
- `/examples/single-image-upload-usage.vue` - 使用示例
