curl -XPOST '127.0.0.1:9200/_reindex?pretty' -H 'content-Type:application/json' -d '{"source": {"remote": {"host": "172.18.11.11:9200"},"index": "commodity"},"dest": {"index": "commodity"}}' -usa:123aaa
 
执行上面命令报
{
  "error" : {
    "root_cause" : [
      {
        "type" : "exception",
        "reason" : "Response didn't include Content-Type: body={\"OK\":{}}"
      }
    ],
    "type" : "exception",
    "reason" : "Response didn't include Content-Type: body={\"OK\":{}}"
  },
  "status" : 500
}

有大佬知道是什么原因吗
