ExpressJS路由無法解析

Question

我有一個用Typescript編寫的小型微服務，該微服務在AKS上的kubernetes集群中運行。 我已經使用Helm生成了入口

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: test-service
  labels:
    app: test-service
    chart: test-service-0.1.0
    release: test-service
    heritage: Tiller
  annotations:
    ingress.kubernetes.io/rewrite-target: /
    kubernetes.io/ingress.class: nginx
    kubernetes.io/tls-acme: "true"
spec:
  tls:
    - hosts:
        - test.xyz
      secretName: default-tls
  rules:
    - host: test.xyz
      http:
        paths:
          - path: /payments
            backend:
              serviceName: test-service
              servicePort: 4040

和服務

apiVersion: v1
kind: Service
metadata:
  name: existing-bumblebee-payments-service
  labels:
    app: test-service
    chart: test-service-0.1.0
    release: existing-bumblebee
    heritage: Tiller
spec:
  type: ClusterIP
  ports:
    - port: 4040
      targetPort: 4040
      protocol: TCP
  selector:
    app: test-service
    release: existing-bumblebee

在我的微服務中

export class Server {
private registerRoutes() {
        this.app.use("/cards", CardRouter);
        this.app.use("/wallets", WalletRouter);
        this.app.use("/preauth", PreauthRouter);
        this.app.use("/charge", ChargeRouter);
    }
}

路由器看起來像這樣；

    import { Router } from "express";
    // other imports
    import { checkSchema, check } from "express-validator/check";

    const router = Router();

    router.get("/", CardController.index);
    router.get("/:id", [
        check("id")
            .isUUID()
            .withMessage("Invalid UUID")
    ], CardController.get);
    router.delete("/:id", [
        check("id")
            .isUUID()
            .withMessage("Invalid UUID")
    ], CardController.remove);
    router.post("/", checkSchema(CardCreateRules), CardController.add);

export default router;

但是，通過https://test.xyz/payments/cards訪問服務會導致來自Express的404錯誤

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <title>Error</title>
    </head>
    <body>
        <pre>Cannot GET /payments/cards</pre>
    </body>
</html>

我可以說響應來自快遞服務器，因為它具有服務器設置的自定義響應頭。 對於什么地方出了問題我真的很困惑，我們將不勝感激。

它對您不起作用，因為您的入口僅將請求https://test.xyz/payments/cards重定向到test-service 而不重寫path 。 因此測試服務仍然成為請求“ /支付/卡”，顯然無法處理它們。

您可以重新配置快遞應用程序以支持/ payments / cards，也可以通過ingess'nginx.ingress.kubernetes.io/rewrite-target'注釋重寫路徑：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: test-service
  labels:
    app: test-service
    chart: test-service-0.1.0
    release: test-service
    heritage: Tiller
  annotations:
    ingress.kubernetes.io/rewrite-target: /
    kubernetes.io/ingress.class: nginx
    kubernetes.io/tls-acme: "true"
    nginx.ingress.kubernetes.io/rewrite-target: /payments
spec:
  tls:
    - hosts:
        - test.xyz
      secretName: default-tls
  rules:
    - host: test.xyz
      http:
        paths:
          - path: /
            backend:
              serviceName: test-service
              servicePort: 4040
