部署包含“文件”类型参数的端点时出错

Question

我正在尝试部署一个包含类型参数的file简单端点。

我将gcloud service-management deploy命令与以下符合 openapi 的 yaml 一起使用：

swagger: "2.0"

info:
  description: "Image API"
  title: "Image API"
  version: "v1"

host: "image-api.endpoints.myproject.cloud.goog"
basePath: "/v1"

schemes:
- "https"

paths:
  "/images":
    post:
      description: "Adds an image"
      operationId: "add"
      consumes:
      - "multipart/form-data"      
      produces:
      - "application/json"
      responses:
        201:
          description: "An image create response"
          schema:
            $ref: "#/definitions/ImageResponse"
      parameters:
      - name: filepath
        in: formData
        required: true
        type: string
      - name: image
        in: formData
        required: false
        type: file

definitions:
  ImageResponse:
    type: object
    properties:
      id:
        type: string
      url:
        type: string
      thumbnail_url:
        type: string

但收到以下错误：

swagger: "2.0"

info:
  description: "Image API"
  title: "Image API"
  version: "v1"

host: "image-api.endpoints.myproject.cloud.goog"
basePath: "/v1"

schemes:
- "https"

paths:
  "/images":
    post:
      description: "Adds an image"
      operationId: "add"
      consumes:
      - "multipart/form-data"      
      produces:
      - "application/json"
      responses:
        201:
          description: "An image create response"
          schema:
            $ref: "#/definitions/ImageResponse"
      parameters:
      - name: filepath
        in: formData
        required: true
        type: string
      - name: image
        in: formData
        required: false
        type: file

definitions:
  ImageResponse:
    type: object
    properties:
      id:
        type: string
      url:
        type: string
      thumbnail_url:
        type: string

如果我取出file参数，则端点部署成功。这是 Google Cloud Endpoint 限制还是有另一种定义方法？

Google Cloud Endpoints 目前不支持上传图片。

您可以先上传到 Google Cloud Storage：https : //cloud.google.com/storage/docs/json_api/v1/how-tos/upload https://cloud.google.com/storage/docs/object-basics

然后将 URL 传递给您的 Google Cloud Endpoints，然后它可以从 Google Cloud Storage 检索图像并执行处理。
