钉钉服务端获取文件上床信息步骤一没有给调用接口如何获resourceUrls和headers参数值。

调用该接口里面有上传文件需要的resourceUrls和headers参数值。请求方法如下：

POST /v1.0/storage/spaces/854xxxxx/files/uploadInfos/query?unionId=cHtUxxxxx HTTP/1.1
Host:api.dingtalk.com
x-acs-dingtalk-access-token:xxxxx
Content-Type:application/json

{
  "protocol" : "HEADER_SIGNATURE",
  "multipart" : false,
  "option" : {
    "storageDriver" : "DINGTALK",
    "preCheckParam" : {
      "md5" : "md5",
      "size" : 512,
      "parentId" : "parent_id",
      "name" : "dentry_name"
    },
    "preferRegion" : "ZHANGJIAKOU",
    "preferIntranet" : true
  }
}

返回示例里可以看到resourceUrls和headers参数值。

HTTP/1.1 200 OK
Content-Type:application/json

{
  "uploadKey" : "upload_key",
  "storageDriver" : "DINGTALK",
  "protocol" : "HEADER_SIGNATURE",
  "headerSignatureInfo" : {
    "resourceUrls" : [ "resource_url" ],
    "headers" : {
      "key" : "header_value"
    },
    "expirationSeconds" : 900,
    "region" : "ZHANGJIAKOU",
    "internalResourceUrls" : [ "internal_resource_url" ]
  }
}
