AWS API Gateway:如何将多个方法请求参数合并为一个集成请求参数 [英] AWS API Gateway: How to combine multiple Method Request params into a single Integration Request param

问题描述

我想使用API​​网关作为S3的代理.该存储区由一个由以下两部分组成的组合键设置键:[userId]-[documentId].

I'd like to use API Gateway as a proxy to S3. The bucket is keyed by a composite key made up of two parts like this: [userId]-[documentId].

UserId作为路径参数进入API网关，documentId作为请求参数进入，例如: [gateway-url]/user1?documentId = doc1

UserId comes to API Gateway as a path parameter, documentId comes in as a request parameter, for example: [gateway-url]/user1?documentId=doc1

如何将两者结合在一起，以使s3查找URL具有以下格式: https://[bucket-url]/user1-doc1 ?

How can I combine the two so that the s3 lookup URL has the following format: https://[bucket-url]/user1-doc1?

谢谢.

推荐答案

1. 设置您的方法请求以接受路径参数{userid}和查询参数{docid}.
2. 设置集成请求以接受 method.request.querystring.docid 和 method.request.path.userid 作为URL路径参数.
3. 最后，将集成端点URL设置为 https://您的URL/ {userid}-{docid}

1. Setup your Method Request to accept the path param {userid} and query param {docid}.
2. Setup your Integration Request to accept both method.request.querystring.docid and method.request.path.userid as URL path params.
3. Finally, setup your integration endpoint URL as https://your-url/{userid}-{docid}.

为此而挥霍的片段如下-

A swagger snippet for this is as follows-

"paths": {
"/concat-params/{userid}": {
  "get": {
    "parameters": [
      {
        "name": "userid",
        "in": "path",
        "required": true,
        "type": "string"
      },
      {
        "name": "docid",
        "in": "query",
        "required": false,
        "type": "string"
      }
    ],
    "responses": {...},
    "x-amazon-apigateway-integration": {
      "responses": {...},
      "requestParameters": {
        "integration.request.path.userid":"method.request.path.userid",
    "integration.request.path.docid":"method.request.querystring.docid"
      },
      "uri": "https:.../{userid}-{docid}",
      ...
    }
  }
}
