Nginx 入口 - 转义字符

我有以下通过 nodePort 32100 公开的入口配置。当我调用 (curl) 包含括号的 URL [1] 时，出现 HTTP 500 错误。但当我调用不包含括号的 URL [2] 时，请求通过 NGINX 入口控制器 (v0.35.0) 成功传递。

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: 0m
    name: test1-app-ingress
  namespace: test1
spec:
  rules:
  - host: ing1.example.com
    http:
      paths:
      - backend:
          serviceName: test1-app-1-ingress
          servicePort: 80
        path: /test1
  - host: ing2.example.com
    http:
      paths:
      - backend:
          serviceName: test1-app-2-ingress
          servicePort: 80
        path: /test1

这是 NGINX IC 的问题吗？我是否应该转义入口配置上的任何字符，例如括号？

答案1

应用程序的日志文件表明请求已到达应用程序。这意味着“500”错误代码是由应用程序发送的。因此，您无法在 nginx 端执行任何操作来修复这种情况。

您需要确保应用程序正确处理请求。
