✅ 对电子商务行业的影响(+5)

🎯 问题陈述:

网上购物中的个人接触差距

传统电子商务平台存在以下问题:

  1. 非个人化浏览:没有像实体店那样的引导式发现
  2. 决策瘫痪:没有专家指导的选择太多
  3. 有限的上下文帮助:不能问“什么最适合越野跑?”
  4. 交易摩擦:查找、比较和购买的多个步骤

行业统计:

  • 70%的在线购物者因购物车的复杂性而放弃购物车
  • 88%的消费者希望获得个性化体验
  • 由于用户体验不佳,每年损失180亿美元

💡 我们的解决方案:对话式商务

GenAI体育 将网上购物转变为 个性化咨询 通过:

1. 自然语言购物
User: "I need shoes for rocky terrain in the mountains"
Finn: "For rocky mountain terrain, I recommend:
      • Ultra Glide - Aggressive tread, ankle support
      • Trail Blazer Pro - Extra cushioning, waterproof
      Which would you like to explore?"

影响:将产品发现时间缩短65%

2. 情境感知建议

代理人记得:

  • 以前的购买
  • 购物清单项目
  • 首选商店
  • 交货偏好

例子:

User: "Find stores near me"
Finn: *Uses stored user location from profile*
      *Suggests stores with inventory for cart items*
3. 无缝多动作工作流

单个对话处理:

  • 产品搜索→ 详情→ 加入购物车→ 查找店铺→ 下单→ 跟踪交货

传统电子商务:8页点击次数超过15次
GenAI体育:1个界面中有6条聊天消息

4. 库存意识建议

与通用产品列表不同,Finn只建议 可用产品 从附近的商店:

-- Behind the scenes query
SELECT p.product_name 
FROM products p
JOIN store_inventory si ON p.product_id = si.product_id
WHERE si.store_id = (SELECT nearest_store FROM user_location)
  AND si.quantity > 0;

🏢 行业应用

零售体育器材 (主要用例)

const Home = ({ idToken, setIdToken }) => {
  const [messages, setMessages] = useState([]);
  const [isChatOpen, setIsChatOpen] = useState(false);
  
  // Streaming response handler
  const handleSendMessage = async () => {
    const response = await fetch(`${BACKEND_URL}/chat`, {
      method: 'POST',
      headers: {
        'Authorization': `Bearer ${idToken}`
      },
      body: JSON.stringify({ message, history })
    });
    
    const reader = response.body.getReader();
    let aiText = "";
    while (true) {
      const { value, done } = await reader.read();
      if (done) break;
      aiText += decoder.decode(value);

gcloud projects add-iam-policy-binding $PROJECT_ID \
  --member="serviceAccount:service-$PROJECT_NUMBER@gcp-sa-alloydb.iam.gserviceaccount.com" \
  --role="roles/aiplatform.user"

3.数据库初始化

# Start AlloyDB Auth Proxy
wget https://storage.googleapis.com/alloydb-auth-proxy/v1.13.6/alloydb-auth-proxy.linux.amd64 -O alloydb-auth-proxy
chmod +x alloydb-auth-proxy
./alloydb-auth-proxy "projects/$PROJECT_ID/locations/$REGION/clusters/alloydb-cluster/instances/alloydb-inst" --public-ip &

# Load schema and data
psql -h 127.0.0.1 -U postgres -c "CREATE DATABASE store;"
psql -h 127.0.0.1 -U postgres -d store -f data/store_backup.sql

4.OAuth配置

# Create OAuth consent screen (via Console)
# Then create OAuth Client ID
gcloud alpha iap oauth-brands create \
  --application_title="GenAI Sports" \
  --support_email=your-email@example.com

# Save the generated CLIENT_ID for later

5.MCP工具箱部署

cd src/toolbox

# Update tools.yaml with your credentials
cat > tools.yaml <<EOF
sources:
  alloydb_source:
    type: alloydb
    host: "/cloudsql/$PROJECT_ID:$REGION:alloydb-cluster/alloydb-inst"
    database: store
    user: postgres
    password: alloydb

authentication_providers:
  google_signin:
    type: oauth_client_id
    client_id: "YOUR_OAUTH_CLIENT_ID.apps.googleusercontent.com"

# ... (rest of tools.yaml)
EOF

# Upload as secret
gcloud secrets create tools --data-file=tools.yaml

# Deploy to Cloud Run
export IMAGE=us-central1-docker.pkg.dev/database-toolbox/toolbox/toolbox:latest
gcloud run deploy toolbox \
  --image $IMAGE \
  --service-account toolbox-identity \
  --region $REGION \
  --set-secrets "/app/tools.yaml=tools:latest" \
  --args="--tools_file=/app/tools.yaml","--address=0.0.0.0","--port=8080" \
  --allow-unauthenticated

6.后端部署

cd src/backend

# Update finn_agent.py with Toolbox URL
TOOLBOX_URL=$(gcloud run services describe toolbox --region=$REGION --format='value(status.url)')
sed -i "s|https://toolbox-.*|$TOOLBOX_URL|g" finn_agent.py

# Build and deploy
gcloud artifacts repositories create finn-agent-images \
  --repository-format=docker \
  --location=$REGION

gcloud builds submit . --tag $REGION-docker.pkg.dev/$PROJECT_ID/finn-agent-images/finn-agent

gcloud run deploy finn-agent \
  --image $REGION-docker.pkg.dev/$PROJECT_ID/finn-agent-images/finn-agent \
  --platform managed \
  --allow-unauthenticated \
  --region $REGION \
  --set-env-vars="GOOGLE_CLOUD_PROJECT=$PROJECT_ID,GOOGLE_CLOUD_LOCATION=$REGION,GOOGLE_GENAI_USE_VERTEXAI=TRUE"

7.前端部署

cd src/frontend

# Update Home.jsx with backend URL
BACKEND_URL=$(gcloud run services describe finn-agent --region=$REGION --format='value(status.url)')
sed -i "s|https://finn-agent-.*|$BACKEND_URL|g" src/pages/Home.jsx

# Update GoogleSignInButton.jsx with OAuth Client ID
sed -i "s|YOUR_OAUTH_CLIENT_ID|YOUR_ACTUAL_CLIENT_ID|g" src/components/GoogleSignInButton.jsx

# Build and deploy
gcloud artifacts repositories create finn-frontend-images \
  --repository-format=docker \
  --location=$REGION

gcloud builds submit . --tag $REGION-docker.pkg.dev/$PROJECT_ID/finn-frontend-images/finn-frontend

gcloud run deploy finn-frontend \
  --image $REGION-docker.pkg.dev/$PROJECT_ID/finn-frontend-images/finn-frontend \
  --platform managed \
  --allow-unauthenticated \
  --region $REGION

8.上传产品图片

# Create Cloud Storage bucket
gsutil mb gs://$PROJECT_ID-images

# Upload images
gsutil -m cp -r images/* gs://$PROJECT_ID-images/images/

# Make public
gsutil iam ch allUsers:objectViewer gs://$PROJECT_ID-images

🧪 测试应用程序

手动测试脚本

# 1. Open frontend URL
FRONTEND_URL=$(gcloud run services describe finn-frontend --region=$REGION --format='value(status.url)')
echo "Visit: $FRONTEND_URL"

# 2. Sign in with Google

# 3. Test conversation flow:
# - "Hello Finn!"
# - "I'm looking for running shoes for an ultra-trail"
# - "Tell me more about Ultra Glide"
# - "Add Ultra Glide, size 40, color Red/Grey to my shopping list"
# - "Show my shopping list"
# - "Find stores near me"
# - "Place an order for Sports Diagonal Mar"
# - "Check the status for my orders"
# - "List delivery methods for Sports Diagonal Mar"
# - "Update to Express Delivery for order #1"
# - "Thanks Finn!"

API测试(后端)

BACKEND_URL=$(gcloud run services describe finn-agent --region=$REGION --format='value(status.url)')

# Test health endpoint
curl $BACKEND_URL/test

# Test chat (requires valid JWT)
curl -X POST "$BACKEND_URL/chat" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -d '{
    "message": "Hello",
    "session_id": "test-session",
    "user_id": "5"
  }'

工具箱测试

TOOLBOX_URL=$(gcloud run services describe toolbox --region=$REGION --format='value(status.url)')

# List available tools
curl "$TOOLBOX_URL/api/toolset"

# Test product search tool
curl -X POST "$TOOLBOX_URL/api/tools/search_products" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_JWT_TOKEN" \
  -d '{"keyword": "running"}'

# Check firewall rules
gcloud compute firewall-rules list --filter="name:allow-ssh"

# Verify VPC peering
gcloud services vpc-peerings list --network=default

问题:未找到工具箱工具

# Verify secret is updated
gcloud secrets versions access latest --secret=tools

# Check toolbox logs
gcloud logging read "resource.labels.service_name=toolbox" --limit 50

# Redeploy with latest secret
gcloud run services update toolbox \
  --update-secrets "/app/tools.yaml=tools:latest"

问题:前端显示“需要登录”

# Verify OAuth Client ID
grep -r "YOUR_OAUTH_CLIENT_ID" src/frontend/

# Check CORS configuration in backend
grep -A5 "CORSMiddleware" src/backend/app.py

# Validate JWT token format
# Should be: Bearer eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9...

问题:双子座的反应被切断

# Increase streaming buffer size in backend
# Edit src/backend/finn_agent.py:
# streaming_config = types.GenerationConfig(max_output_tokens=8192)
