在GCP API网关中上传文件

Question

后端URL）创建以下 API配置

swagger: '2.0'
info:
  title: upload
  description: upload
  version: 1.0.0
schemes:
  - https
produces:
  - application/json
security:
  - api_key: [ ]

paths:
  /upload:
    post:
      summary: uploads a file.
      consumes:
        - multipart/form-data
      operationId: uploadFile
      parameters:
        - in: formData
          name: file
          description: The file to upload.
          required: true
          type: file
      responses:
        '200':
          description: upload successful
      x-google-backend:
        address: https://XXXXX.XXXXX
        path_translation: APPEND_PATH_TO_ADDRESS    

securityDefinitions:
  api_key:
    type: "apiKey"
    name: "key"
    in: "query" 

我正在尝试为 GCP API Gateway （OMMUTTENT的真实

网关api-configs create uploadConfig -api = [api] -openapi-spec = OpenApi.yaml -project = [myProject] -backend-auth-service-account = [account]

这将导致此错误消息：

错误：（ gcloud.api-gateway.api-configs.create）invalid_argument：无法转换为服务配置。 '位置：“未知位置” 类型：错误 消息：“ http：重复消息字段'google.protobuf.struct.fields'通过消息'uploadfilerequest'所引用的'无法映射为http参数。” 位置：“未知位置” 类型：错误 消息：“ http：循环消息字段'google.protobuf.struct.fieldsentry.value'通过消息'uploadfilerequest'方法'方法'方法'方法1.xxxxxxxx.uploadfile'无法映射为HTTP参数。

我使用不同的API配置和后端验证了GCLOUD命令。

配置本身看起来不错，即使用Swagger Editor进行验证，GCLOUD仍然不接受。 如何通过API网关定义上传文件？

Answer 1

按照 file uplota类型：文件用于文件上传参数，类型：String 应该使用。我尝试了配置随着参数的更改，它用Swagger编辑器结果验证为在这里。

Answer 2

使用SwaggerHub和OpenAPI 2规格，这就是我将此文件上传工作的方式。让我知道您是否有任何疑问。这是用YAML而不是JSON规格编写的。它花了一些阅读和一些实验，但这是GCLOUD文档： htttps：htttps：// cloud。 google.com/storage/docs/uploading-objects
以及SwaggerHub信息：

  /upload/storage/v1/b/{bucket}/o?uploadType=media&name={objectName}:
    post:
      summary: Upload an object directly to a bucket
      description: Upload an object directly to a bucket
      consumes:
        - multipart/form-data
      produces:
        - application/json
      parameters:
        - in: header
          name: Authorization
          type: string
          required: true
        - in: path
          name: bucket
          required: true
          type: string
          description: The name of the bucket to upload to.
        - in: path
          name: objectName
          required: true
          type: string
          description: The name the object will receive in the bucket.
        - in: header
          name: Content-Type
          type: string
          required: true
          description: The content type of the upload. Ex. text/plain
        - in: formData
          name: fileToUpload
          type: file
          description: The file to upload.
      responses:
        200:
          description: OK
        204:
          description: Success - No Content
        400:
          description: Bad Request
        401:
          description: Insufficient Privileges
        404:
          description: Not Found

它确实接受类型：formdata请求中的文件。
