elasticsearch - 使用Curl将数据放入ES中并获得意外字符('n'(代码110))

Question

我正在使用Curl将数据放入ES。我已经创建了一个customer索引。
以下命令来自ES document。

curl -X PUT "localhost:9200/customer/_doc/1?pretty" -H 'Content-Type: application/json' -d'
{
  "name": "John Doe"
}
'

当我这样做时，我得到一个错误。

{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "failed to parse"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "failed to parse",
    "caused_by" : {
      "type" : "json_parse_exception",
      "reason" : "Unexpected character ('n' (code 110)): was expecting double-quote to start field name\n at [Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper@1ec5236e; line: 3, column: 4]"
    }
  },
  "status" : 400
}

我认为，以下是我出错的主要原因。

reason" : "Unexpected character ('n' (code 110)): was expecting double-quote to start field name

我觉得我需要使用(反斜杠)逃脱。但是，我的尝试 \'效果不佳。有什么建议吗？

我使它像下面一样工作。

curl -X PUT "localhost:9200/customer/_doc/1?pretty" -H 'Content-Type: application/json' -d '
{
    \"name\": \"John Doe\"             <====  I used "backslash"  in front of all the " 
}
' 

回答不加评论:

curl -X PUT "localhost:9200/customer/_doc/1?pretty" -H 'Content-Type: application/json' -d '
{
    \"name\": \"John Doe\"              
}
'
