          "weighted_upstreams": [
            {
              "upstream_id": 1,
              "weight": 9
            },
            {
              "upstream_id": 2,
              "weight": 1
            }
          ]
        }
      ]
    }
  },
  "upstream_id": 1
}'

        {"upstream_id": 2, "weight": 5}
      ]
    }
  ]
}'

# 100% v2(完全切换)
curl -X PUT http://127.0.0.1:9180/apisix/admin/routes/1 \
-H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" \
-d '{
  "uri": "/api/users/*",
  "upstream_id": 2
}'

步骤4:基于Header的灰度(内部测试)

curl -X PUT http://127.0.0.1:9180/apisix/admin/routes/1 \
-H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" \

3.2 缓存策略

代理缓存(proxy-cache)

curl -X PUT http://127.0.0.1:9180/apisix/admin/routes/1 \
-H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" \
-d '{
  "uri": "/api/products/*",
  "methods": ["GET"],
  "plugins": {
    "proxy-cache": {
      "cache_zone": "disk_cache_one",
      "cache_key": ["$host", "$request_uri"],
      "cache_bypass": ["$arg_bypass"],
      "cache_method": ["GET"],
      "cache_http_status": [200, 301, 404],
      "hide_cache_headers": true,
      "cache_control": false,
      "no_cache": ["$arg_no_cache"]
    }
  },
  "upstream_id": "1"
}'

配置说明

  • cache_zone:缓存区域(需在config.yaml中定义)
  • cache_key:缓存键($host + $request_uri)
  • cache_bypass:绕过缓存条件(存在bypass参数时)
  • cache_http_status:缓存的HTTP状态码
  • hide_cache_headers:隐藏缓存相关Header

-H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" \
-d '{
  "uri": "/api/payment",
  "methods": ["POST"],
  "plugins": {
    "request-id": {
      "header_name": "X-Request-ID",
      "algorithm": "uuid"
    },
    "serverless-pre-function": {
      "phase": "rewrite",
      "functions": [
        "return function(conf, ctx)
          local core = require(\"apisix.core\")
          local redis = require(\"resty.redis\")
          local red = redis:new()
          red:connect(\"127.0.0.1\", 6379)

          local request_id = ctx.var.http_x_request_id
          local exists = red:exists(\"req:\" .. request_id)
          if exists == 1 then
            return 409, {error = \"重复请求\"}
          end

          red:setex(\"req:\" .. request_id, 300, 1)
        end"
      ]
    }
  },
  "upstream_id": "1"
}'

第五部分:监控与可观测性

5.1 Prometheus监控

配置Prometheus插件

curl -X PUT http://127.0.0.1:9180/apisix/admin/global_rules/1 \
-H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" \
-d '{
  "plugins": {
    "prometheus": {
      "prefer_name": true
    }
  }
}'

Prometheus配置

# prometheus.yml
scrape_configs:
  - job_name: 'apisix'
    metrics_path: '/apisix/prometheus/metrics'
    static_configs:
      - targets: ['127.0.0.1:9091']

关键指标

  • apisix_http_status:HTTP状态码分布
  • apisix_http_latency:请求延迟分位数
  • apisix_bandwidth:带宽使用量
  • apisix_nginx_http_current_connections:当前连接数

5.2 分布式追踪(SkyWalking)

curl -X PUT http://127.0.0.1:9180/apisix/admin/routes/1 \
-H "X-API-KEY: edd1c9f034335f136f87ad84b625c8f1" \
-d '{
  "uri": "/api/*",
  "plugins": {
    "skywalking": {
      "endpoint_addr": "http://skywalking-oap:12800",
      "service_name": "APISIX-Gateway",
      "service_instance_name": "APISIX-Node-1"
    }
  },
  "upstream_id": "1"
}'

第六部分:故障排查手册

6.1 常见问题诊断

问题1:502 Bad Gateway

可能原因

  1. 上游服务不可用
  2. 上游地址配置错误
  3. 连接超时

排查步骤

# 1. 检查上游配置
curl http://127.0.0.1:9180/apisix/admin/upstreams/1 \
-H "X-API-KEY: xxx"

# 2. 直接访问上游服务
curl http://upstream-host:8080/health

# 3. 查看APISIX错误日志
tail -f /usr/local/apisix/logs/error.log | grep "502"

# 4. 查看上游响应时间
tail -f /usr/local/apisix/logs/access.log | grep "upstream_response_time"
