## JavaScript/Node.js
### 使用 axios
```javascript
const axios = require('axios');
const FormData = require('form-data');
const fs = require('fs');
async function removeWatermark(imagePath, maskPath = null, apiKey = 'your_secret_key_change_me') {
const url = 'http://localhost:8080/api/v1/remove-watermark';
const formData = new FormData();
formData.append('image', fs.createReadStream(imagePath));
if (maskPath) {
formData.append('mask', fs.createReadStream(maskPath));
}
try {
const response = await axios.post(url, formData, {
headers: {
'X-API-Key': apiKey,
...formData.getHeaders()
},
responseType: 'arraybuffer',

```bash
# 简单调用
curl -X POST http://localhost:8080/api/v1/remove-watermark \
-H "X-API-Key: your_secret_key_change_me" \
-F "image=@input.jpg" \
-o result.png
# 带遮罩
curl -X POST http://localhost:8080/api/v1/remove-watermark \
-H "X-API-Key: your_secret_key_change_me" \
-F "image=@input.jpg" \
-F "mask=@mask.png" \
-o result.png

```
### Bash脚本批量处理
```bash
#!/bin/bash
API_URL="http://localhost:8080/api/v1/remove-watermark"
API_KEY="your_secret_key_change_me"
INPUT_DIR="./input"
OUTPUT_DIR="./output"
mkdir -p "$OUTPUT_DIR"
for image in "$INPUT_DIR"/*.{jpg,jpeg,png}; do
[ -f "$image" ] || continue
filename=$(basename "$image")
name="${filename%.*}"
output="$OUTPUT_DIR/${name}_result.png"
echo "处理: $filename"
curl -X POST "$API_URL" \

## 错误处理
### 常见错误代码
| 状态码 | 错误 | 解决方案 |
|--------|------|----------|
| 401 | 未授权 | 检查API Key是否正确 |
| 400 | 请求错误 | 检查图片格式、大小是否符合要求 |
| 429 | 请求过多 | 降低请求频率,稍后重试 |
| 500 | 服务器错误 | 检查服务器日志,联系技术支持 |
| 503 | 服务不可用 | 服务器可能正在重启,稍后重试 |
### 限流说明
默认限流每秒10个请求突发20个请求
如果遇到429错误建议
1. 使用指数退避重试策略
2. 减少并发请求数
3. 联系管理员增加配额
---
## 性能优化建议
1. **批量处理**合理控制并发数建议2-4个并发
2. **图片预处理**:压缩大图片后再上传
3. **复用连接**使用HTTP keep-alive
4. **错误重试**:实现指数退避策略
5. **超时设置**:根据图片大小设置合理超时时间

# IOPaint 去水印 API 服务设计方案
## 📋 目录
1. [MVP 最小可行产品](#mvp-最小可行产品)
2. [商业化架构设计](#商业化架构设计)
3. [部署方案对比](#部署方案对比)
4. [成本与扩展性分析](#成本与扩展性分析)
---
## 🚀 MVP 最小可行产品
### 设计原则KISS
- **单一功能**只提供去水印API不包含WebUI
- **单一模型**只使用LaMa模型快速、低资源
- **简单认证**API Key认证
- **本地存储**:无需对象存储
- **单机部署**Docker Compose即可
### 核心改造
#### 1. 精简API服务 (`api_service.py`)
```python
# 只保留核心功能:
# - POST /api/v1/remove-watermark - 去水印接口
# - GET /api/v1/health - 健康检查
# - GET /api/v1/usage - 使用统计(可选)
# 移除功能:
# - WebUI相关路由
# - 多模型支持
# - 插件系统
# - 文件浏览器
# - Socket.IO实时通信
```
#### 2. API接口设计
**去水印接口**
```bash
POST /api/v1/remove-watermark
Headers:
X-API-Key: your_api_key_here
Content-Type: multipart/form-data
Body:
image: file (必需) - 原始图片
mask: file (可选) - 水印遮罩,不提供则自动检测
Response:
- 200: 返回处理后的图片image/png
- 401: API Key无效
- 400: 参数错误
- 500: 处理失败
```
**健康检查**
```bash
GET /api/v1/health
Response: {"status": "ok", "model": "lama"}
```
#### 3. MVP部署架构
```
┌─────────────────────────────────────┐
│ Nginx (反向代理) │
│ - SSL终止 │
│ - 限流 (rate limiting) │
│ - 日志记录 │
└──────────────┬──────────────────────┘
┌──────────────▼──────────────────────┐
│ IOPaint API Service │
│ - FastAPI │
│ - LaMa模型 │
│ - API Key认证 │
│ - 本地存储 │
└─────────────────────────────────────┘
```
#### 4. MVP Docker配置
**单容器方案**:适合月处理量 < 10万张
```yaml
# docker-compose.mvp.yml
version: '3.8'
services:
api:
build:
context: .
dockerfile: docker/APIDockerfile
ports:
- "8080:8080"
environment:
- API_KEY=your_secret_key_here
- MAX_IMAGE_SIZE=4096
- ENABLE_METRICS=true
volumes:
- ./models:/root/.cache
- ./logs:/app/logs
restart: unless-stopped
deploy:
resources:
limits:
cpus: '2'
memory: 4G
```
**成本估算MVP阶段**
- **云服务器**2核4G约¥200-300/月(阿里云、腾讯云)
- **存储**100GB SSD约¥50/月
- **流量**100GB/月约¥50/月
- **总计**约¥300-400/月
**性能预估**
- 处理速度约1-2秒/张1024x1024
- 并发能力2-4个请求
- 月处理量:~5-10万张
---
## 🏢 商业化架构设计
### 设计原则
- **横向扩展**:支持动态增减实例
- **高可用**:无单点故障
- **异步处理**:支持批量和队列
- **监控完善**:实时监控和告警
- **成本优化**:按需扩展
### 商业化架构图

### 核心组件
#### 1. API层Kubernetes部署
**api-deployment.yaml**
```yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: iopaint-api
spec:
replicas: 3 # 根据负载自动扩展
template:
spec:
containers:
- name: api
image: let5sne/iopaint-api:latest
resources:
requests:
memory: "4Gi"
cpu: "2"
nvidia.com/gpu: 1
limits:
memory: "8Gi"
cpu: "4"
nvidia.com/gpu: 1
env:
- name: REDIS_URL
value: "redis://redis:6379"
- name: S3_BUCKET
value: "iopaint-images"
```
#### 2. 异步任务队列Redis + Celery
**好处**
- 避免API超时
- 支持批量处理
- 可重试失败任务
- 平滑处理流量峰值
**工作流程**
```
1. 用户上传图片 → API返回任务ID
2. 图片存入S3 → 任务推入Redis队列
3. Celery Worker异步处理
4. 处理完成 → 更新数据库 → 触发回调/Webhook
```
#### 3. 数据库设计PostgreSQL
```sql
-- 用户表
CREATE TABLE users (
id SERIAL PRIMARY KEY,
api_key VARCHAR(64) UNIQUE NOT NULL,
plan VARCHAR(20) NOT NULL, -- free, basic, pro, enterprise
quota_monthly INT NOT NULL,
quota_used INT DEFAULT 0,
created_at TIMESTAMP DEFAULT NOW()
);
-- 任务表
CREATE TABLE tasks (
id UUID PRIMARY KEY,
user_id INT REFERENCES users(id),
status VARCHAR(20) NOT NULL, -- pending, processing, completed, failed
image_url TEXT NOT NULL,
result_url TEXT,
created_at TIMESTAMP DEFAULT NOW(),
completed_at TIMESTAMP,
processing_time_ms INT
);
-- 使用统计表(按日汇总)
CREATE TABLE usage_stats (
date DATE NOT NULL,
user_id INT REFERENCES users(id),
requests_count INT DEFAULT 0,
success_count INT DEFAULT 0,
avg_processing_time_ms INT,
PRIMARY KEY (date, user_id)
);
```
#### 4. 监控与告警
**Prometheus指标**
```python
# 核心业务指标
requests_total = Counter('api_requests_total', 'Total API requests', ['status', 'endpoint'])
processing_time = Histogram('image_processing_seconds', 'Image processing time')
model_inference_time = Histogram('model_inference_seconds', 'Model inference time')
queue_size = Gauge('redis_queue_size', 'Current queue size')
gpu_utilization = Gauge('gpu_utilization', 'GPU utilization %')
```
**告警规则**
- API错误率 > 5%
- 队列积压 > 1000
- GPU利用率 > 90%持续5分钟
- 响应时间 > 10秒P95
#### 5. 成本优化策略
**弹性伸缩**
```yaml
apiVersion: autoscaling/v2
kind: HorizontalPodAutoscaler
metadata:
name: iopaint-api-hpa
spec:
scaleTargetRef:
apiVersion: apps/v1
kind: Deployment
name: iopaint-api
minReplicas: 2
maxReplicas: 10
metrics:
- type: Resource
resource:
name: cpu
target:
type: Utilization
averageUtilization: 70
- type: Resource
resource:
name: nvidia.com/gpu
target:
type: Utilization
averageUtilization: 80
```
**Spot实例**
- 使用云厂商Spot/抢占式实例成本降低60-80%
- 配合优先级队列,重要任务用按需实例

## Introduction
The IOPaint API provides AI-powered watermark removal capabilities through a simple REST API. Built on the LaMa (Large Mask Inpainting) model, it offers fast and high-quality image restoration.
### Key Features
- **Fast Processing**: 1-2 seconds for 1024x1024 images
- **High Quality**: State-of-the-art AI model
- **Simple Integration**: Standard REST API with multipart/form-data
- **Flexible**: Optional mask support for precise control
- **Scalable**: From hobby projects to enterprise deployments
### API Capabilities
| Feature | Status | Description |
|---------|--------|-------------|
| Watermark Removal | ✅ Available | Remove watermarks from images |
| Auto Detection | ⏳ Coming Soon | Automatic watermark detection |
| Batch Processing | ⏳ Coming Soon | Process multiple images at once |
| Webhook Callbacks | ⏳ Coming Soon | Async processing with callbacks |
---
## Authentication
The IOPaint API uses API keys for authentication. All requests must include your API key in the request header.
### Obtaining an API Key
1. Sign up at [https://iopaint.com/signup](https://iopaint.com/signup)
2. Navigate to your [Dashboard](https://iopaint.com/dashboard)
3. Generate a new API key
4. Store it securely (keys cannot be recovered)
### Using Your API Key
Include your API key in the `X-API-Key` header with every request:
```http
X-API-Key: your_api_key_here
```
### Security Best Practices
- ⚠️ **Never expose your API key in client-side code**
- ✅ Store keys in environment variables
- ✅ Rotate keys periodically
- ✅ Use different keys for development and production
- ✅ Revoke compromised keys immediately
### Example
```bash
# ✅ Correct
curl https://api.iopaint.com/api/v1/health \
-H "X-API-Key: $IOPAINT_API_KEY"
# ❌ Incorrect (hardcoded key)
curl https://api.iopaint.com/api/v1/health \
-H "X-API-Key: sk_live_1234567890abcdef"
```

### Error Handling Best Practices
```python
import requests
import time
def remove_watermark_with_retry(image_path, max_retries=3):
"""Remove watermark with exponential backoff retry"""
url = "https://api.iopaint.com/api/v1/remove-watermark"
headers = {"X-API-Key": os.getenv("IOPAINT_API_KEY")}
for attempt in range(max_retries):
try:
with open(image_path, "rb") as f:
response = requests.post(
url,
headers=headers,
files={"image": f},
timeout=120
)
if response.status_code == 200:
return response.content
elif response.status_code == 429:
# Rate limit - exponential backoff
wait_time = 2 ** attempt
print(f"Rate limited. Waiting {wait_time}s...")
time.sleep(wait_time)
continue
elif response.status_code in [500, 503]:
# Server error - retry
if attempt < max_retries - 1:
time.sleep(2 ** attempt)
continue
else:
raise Exception(f"Server error: {response.json()}")
else:
# Client error - don't retry
raise Exception(f"Error {response.status_code}: {response.json()}")
except requests.Timeout:
if attempt < max_retries - 1:
print(f"Timeout. Retrying... ({attempt + 1}/{max_retries})")
continue
else:
raise
raise Exception("Max retries exceeded")
```
---
## Rate Limiting
### Rate Limit Rules
| Plan | Rate Limit | Burst | Quota |
|------|------------|-------|-------|
| **Free** | 2 req/min | 5 | 10/day |
| **Basic** | 10 req/min | 20 | 3,000/month |
| **Pro** | 30 req/min | 60 | 20,000/month |
| **Enterprise** | Custom | Custom | Custom |
### Rate Limit Headers
Every response includes rate limit information:
```http
X-RateLimit-Limit: 10
X-RateLimit-Remaining: 7
X-RateLimit-Reset: 1672531200
```
| Header | Description |
|--------|-------------|
| `X-RateLimit-Limit` | Maximum requests per time window |
| `X-RateLimit-Remaining` | Remaining requests in current window |
| `X-RateLimit-Reset` | Unix timestamp when limit resets |
### Handling Rate Limits
```python
import requests
import time
def wait_for_rate_limit_reset(response):
"""Wait until rate limit resets"""
if response.status_code == 429:
reset_time = int(response.headers.get('X-RateLimit-Reset', 0))
current_time = int(time.time())
wait_time = max(0, reset_time - current_time)
print(f"Rate limited. Waiting {wait_time}s for reset...")
time.sleep(wait_time + 1) # Add 1s buffer
return True
return False
```
### Best Practices
1. **Check remaining quota** before making requests
2. **Implement exponential backoff** for retries
3. **Cache results** to avoid duplicate requests
4. **Use batch endpoints** (when available) for multiple images
5. **Upgrade your plan** if consistently hitting limits
---
## Best Practices
### Performance Optimization
#### 1. Image Preprocessing
```python
from PIL import Image
def optimize_image(image_path, max_size=2048):
"""Resize large images before upload"""
img = Image.open(image_path)
# Check if resize needed
if max(img.size) > max_size:
ratio = max_size / max(img.size)
new_size = tuple(int(dim * ratio) for dim in img.size)
img = img.resize(new_size, Image.LANCZOS)
# Convert to RGB if needed
if img.mode != 'RGB':
img = img.convert('RGB')
# Save optimized
output = "optimized.jpg"
img.save(output, quality=95, optimize=True)
return output
```
#### 2. Concurrent Processing
```python
from concurrent.futures import ThreadPoolExecutor
import requests
def process_batch(image_paths, api_key, max_workers=4):
"""Process multiple images concurrently"""
def process_one(path):
headers = {"X-API-Key": api_key}
with open(path, "rb") as f:
response = requests.post(
"https://api.iopaint.com/api/v1/remove-watermark",
headers=headers,
files={"image": f}
)
return path, response
with ThreadPoolExecutor(max_workers=max_workers) as executor:
results = list(executor.map(process_one, image_paths))
return results
```
#### 3. Connection Reuse
```python
import requests
# Reuse session for multiple requests
session = requests.Session()
session.headers.update({"X-API-Key": api_key})
for image_path in image_paths:
with open(image_path, "rb") as f:
response = session.post(
"https://api.iopaint.com/api/v1/remove-watermark",
files={"image": f}
)
```
### Security
#### Environment Variables
```bash
# .env file
IOPAINT_API_KEY=sk_live_1234567890abcdef
# .gitignore
.env
```
```python
import os
from dotenv import load_dotenv
load_dotenv()
api_key = os.getenv("IOPAINT_API_KEY")
```
#### API Key Rotation
```python
# Rotate keys periodically
def rotate_api_key():
old_key = os.getenv("IOPAINT_API_KEY")
new_key = generate_new_key() # From dashboard
# Test new key
test_response = requests.get(
"https://api.iopaint.com/api/v1/health",
headers={"X-API-Key": new_key}
)
if test_response.status_code == 200:
# Update environment
update_env("IOPAINT_API_KEY", new_key)
# Revoke old key from dashboard
revoke_key(old_key)
```
### Cost Optimization
#### 1. Cache Results
```python
import hashlib
import os
def get_cached_result(image_path):
"""Check if result already cached"""
# Generate cache key from file content
with open(image_path, "rb") as f:
file_hash = hashlib.md5(f.read()).hexdigest()
cache_path = f"cache/{file_hash}.png"
if os.path.exists(cache_path):
return cache_path
return None
def process_with_cache(image_path, api_key):
"""Process with caching"""
# Check cache first
cached = get_cached_result(image_path)
if cached:
print(f"✓ Using cached result: {cached}")
return cached
# Process via API
result = remove_watermark(image_path, api_key)
# Save to cache
with open(image_path, "rb") as f:
file_hash = hashlib.md5(f.read()).hexdigest()
cache_path = f"cache/{file_hash}.png"
with open(cache_path, "wb") as f:
f.write(result)
return cache_path
```
#### 2. Monitor Usage
```python
def check_quota_before_request(api_key):
"""Check quota before making expensive requests"""
headers = {"X-API-Key": api_key}
response = requests.get(
"https://api.iopaint.com/api/v1/stats",
headers=headers
)
stats = response.json()
quota_used = stats['total']
plan_limit = 3000 # Basic plan
remaining = plan_limit - quota_used
if remaining < 100:
print(f"⚠️ Warning: Only {remaining} requests remaining!")
return remaining > 0
```

## 🔧 API 服务修复
### 问题诊断
**发现的问题**:
1.`ApiConfig` 需要太多不必要的字段21个验证错误
2. ❌ PIL 图像对象未转换为 numpy 数组
3. ❌ ModelManager 期望 numpy 数组作为输入
### 修复措施
**代码修改**:
1. **移除 ApiConfig 依赖**
```python
# 之前
api_config = ApiConfig(host="0.0.0.0", port=8080, ...)
model_manager = ModelManager(name=api_config.model, ...)
# 之后
model_manager = ModelManager(
name=Config.MODEL_NAME,
device=torch.device(Config.DEVICE),
...
)
```
2. **添加图像转换**
```python
# 添加
import numpy as np
# 转换 PIL 为 numpy
image_np = np.array(pil_image)
mask_np = np.array(mask_pil)
# 传递给模型
result_image = model_manager(image=image_np, mask=mask_np, config=inpaint_request)
```
