政府端API 404错误问题分析报告

问题描述

错误URL: https://ad.ningmuyun.com/api/government/market-price?type=beef
错误状态: 404 Not Found
影响范围: 政府端管理系统市场价格功能

问题根因分析

1. 后端代码检查 ✅

路由配置: government-backend/routes/government.js 第11行

router.get('/market-price', governmentController.getMarketPrice);

控制器方法: governmentController.getMarketPrice 已正确实现

应用路由注册: app.js 第50行已正确注册

app.use('/api/government', require('./routes/government'));

2. 前端代码检查 ✅

API调用: government-admin/src/views/MarketPrice.vue 第94行

const response = await axios.get('/api/government/market-price', {
  params: { type }
})

代理配置: vite.config.js 开发环境代理配置正确

3. Nginx配置问题 ❌

问题所在: nginx配置中政府API的路径匹配错误

原始错误配置:

location ^~ /government/api/ {
    proxy_pass http://localhost:5352/;
}

问题分析:

前端请求路径: /api/government/market-price
nginx匹配路径: /government/api/
路径不匹配导致404错误

解决方案

修复nginx配置

将政府API代理路径从 /government/api/ 修改为 /api/government/:

# 政府API代理 - 修复路径匹配问题
location ^~ /api/government/ {
    proxy_pass http://localhost:5352/api/government/;
    proxy_set_header Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto $scheme;
    
    # CORS配置
    add_header 'Access-Control-Allow-Origin' 'https://ad.ningmuyun.com' always;
    add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE' always;
    add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type, X-Requested-With' always;
    add_header 'Access-Control-Allow-Credentials' 'true' always;
    
    if ($request_method = 'OPTIONS') {
        add_header 'Access-Control-Allow-Origin' 'https://ad.ningmuyun.com';
        add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS, PUT, DELETE';
        add_header 'Access-Control-Allow-Headers' 'Authorization, Content-Type, X-Requested-With';
        add_header 'Access-Control-Allow-Credentials' 'true';
        add_header 'Content-Type' 'text/plain; charset=UTF-8';
        add_header 'Content-Length' 0;
        return 204;
    }
}

部署步骤

备份当前nginx配置:

sudo cp /etc/nginx/conf.d/ningmuyun_one.conf /etc/nginx/conf.d/ningmuyun_one.conf.backup

应用修复配置:

sudo cp nginx-fix-government-api.conf /etc/nginx/conf.d/
# 或者手动编辑配置文件，将上述配置添加到 ad.ningmuyun.com server 块中

测试nginx配置:
```
sudo nginx -t
```
重新加载nginx:
```
sudo systemctl reload nginx
```

验证修复:

curl -k https://ad.ningmuyun.com/api/government/market-price?type=beef

预期结果

修复后，https://ad.ningmuyun.com/api/government/market-price?type=beef 应该返回正确的市场价格数据，而不是404错误。
