API网关 - 发布multipart \ form-data

  API网关当前不支持多部分表单数据 . 这正在考虑用于未来的发展 . 在此期间，您需要修改您的客户端以使用多个请求或单个部分请求 .

  Update ：API网关现在支持二进制有效负载 . 只需将"multipart/form-data"定义为API的二进制媒体类型，并将有效负载直接代理到Lambda函数 . 从那里你可以解析正文以获取你的文件内容 . 应该有可用于帮助解析多部分主体的库（例如，NodeJS中的'parse-multipart'） .

  似乎有一个变化，API网关不再对整个Content-Type标头值进行严格匹配，所以现在“二进制”支持的所有内容都按预期工作 .

  将您的API设置为POST（或PUT）并将Lambda集成设置为"proxy" . 转到API的“设置”，然后添加要用作"binary"的媒体类型 . 我添加了 multipart/signed . 接收的媒体类型实际上是： Content-Type: multipart/signed; protocol="application/pkcs7-signature"; micalg="sha256"; boundary="----54645645645664564563424768"

  API GW仍然选择“二进制”并将其作为base64传递给我的Lambda .

  在你的Lambda中你会发现：

  我有同样的问题与我的tomcat服务器集成，我发现下面需要修改它来修改它 .

  • 通过控制台在api网关的api的 HTTP Request Headers 中添加 Content-Type ，或者在open api文档中添加

  {
      "/yourApi":{
          "post":{
              "operationId":"uploadImageUsingPOST",
              "produces":[
                  "application/json"
              ],
              "parameters":[
              {
                  "name":"Content-Type",
                  "in":"header",
                  "required":false,
                  "type":"string"
              },
              {
                  //Other headers
              }]   
          }
      }
  

  • 上面的步骤还在你的api的HTTP集成请求中添加Content-Type，如果没有在那里添加它，并通过控制台在api网关中添加一个 Headers Accept ='/' 或者在open api文档中添加它

  "requestParameters":{
      "integration.request.header.Accept":"'*/*'",
      "integration.request.header.Content-Type":"method.request.header.Content-Type",
      //Other headers
  }
  

  • 在api的集成请求中将内容处理设置为直通 .

  • 通过控制台或打开的api文档在api的设置中将multipart / form-data添加为二进制媒体类型

  "x-amazon-apigateway-binary-media-types": [
      "multipart/form-data"
  ]
  

  • 将上面的部署更改为您要将图像作为multipart上传的所需阶段 .

  Api网关将您的多部分文件作为二进制数组传递，您仍然可以在控制器中使用@RequestBody MultipartFile multipartFile，spring会将此二进制文件解析为多部分 .
