404响应Method: 1.api_endpoints_gcp_project_cloud_goog.Postoperation failed: NOT_FOUND

我正在尝试将我的API与Google Cloud端点一起通过GKE后端进行部署。我在生产的API日志中看到此错误，显示如下：

Method: 1.api_endpoints_gcp_project_cloud_goog.Postoperation failed: NOT_FOUND

我从端点收到404响应。

后端容器正确回答，但是当我尝试发布http://[service-ip]/v1/postoperation时，出现404错误。我猜它与api_method名称有关，但是我已经更改了，因此在openapi.yaml，gke部署和app.py中都是相同的。

我使用以下openapi.yaml成功部署了API服务：

swagger: "2.0"
info:
  description: "API rest"
  title: "API example"
  version: "1.0.0"
host: "api.endpoints.gcp-project.cloud.goog"
basePath: "/v1"
# [END swagger]
consumes:
- "application/json"
produces:
- "application/json"
schemes:
# Uncomment the next line if you configure SSL for this API.
#- "https"
- "http"
paths:
  "/postoperation":
    post:
      description: "Post operation 1"
      operationId: "postoperation"
      produces:
      - "application/json"
      responses:
        200:
          description: "success"
          schema:
            $ref: "#/definitions/Model"
        400:
          description: "Error"
      parameters:
      - description: "Description"
        in: body
        name: payload
        required: true
        schema:
          $ref: "#/definitions/Resource"

definitions:
  Resource:
    type: "object"
    required:
    - "text"
    properties:
      tipodni:
        type: "string"
      dni:
        type: "string"
      text:
        type: "string"

  Model:
    type: "object"
    properties:
      tipodni:
        type: "string"
      dni:
        type: "string"
      text:
        type: "string"
      mundo:
        type: "string"
      cluster:
        type: "string"
      equipo:
        type: "string"
      complejidad:
        type: "string"

然后我尝试使用这个deploy.yaml和lb-deploy.yaml配置后端和esp

apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
  name: api-deployment
  namespace: development
spec:
  strategy:
    type: Recreate

    matchLabels:
      app: api1
  replicas: 2 # tells deployment to run 2 pods matching the template
  template:
    metadata:
      labels:
        app: api1
    spec:
      volumes:
        - name: google-cloud-key
          secret:
            secretName: secret-key

      containers:
      - name: api-container
        image: gcr.io/gcp-project/docker-pqr:IMAGE_TAG_PLACEHOLDER
        volumeMounts:
        - name: google-cloud-key
          mountPath: /var/secrets/google
        ports:
        - containerPort: 5000

      - name: esp
        image: gcr.io/endpoints-release/endpoints-runtime:1
        args: [
          "--http_port=8081","--backend=127.0.0.1:5000","--service=api.endpoints.gcp-project.cloud.goog","--rollout_strategy=managed"
        ]
        ports:
        - containerPort: 8081

kind: Service

    app: api1
  ports:
  - protocol: TCP
    port: 80
    targetPort: 8081

为api提供服务的我的flask应用程序就是这个app.py

app = flask(__name__)

categorizador = Categorizador(model_properties.paths)

@app.route('/postoperation',methods=['POST'])
def postoperation():

    text = request.get_json().get('text','')
    dni = request.get_json().get('dni','')
    tipo_dni = request.get_json().get('tipo_dni','')

    categoria,subcategoria = categorizador.categorizar(text)

    content = {
        'tipodni': tipo_dni,'dni': dni,'text': text,'mundo': str(categoria),'cluster': str(subcategoria),'equipo': '','complejidad': ''
    }

    return jsonify(content)
