创建索引时如何解决“无法解析内容以映射”错误？

Question

我遇到错误。

错误：

  

“ {”错误“：{” root_cause“：[{” type“：” parse_exception“，”原因“：”无法解析内容以映射“”]]，“ type”：“ parse_exception”，“原因” ：“无法解析内容以映射”，“ caused_by”：{“ type”：“ json_parse_exception”，“原因”：“意外字符（'s'（代码115））：期望双引号开头字段名称\ n在[来源：org.elasticsearch.transport.netty4.ByteBufStreamInput@38a4cd00;行：2，列：3]“}}，”状态“：400}”在尝试创建索引时出现错误

代码：

我不确定您使用的是哪个版本的Elasticsearch，但我使用的是6.7，这是经过两次修改后才可以使用的版本

1) I added "_doc"
2) I moved `"required": { "type": "boolean"}`  to one curly below ... look at it and it will make sense

这是对我有用的映射

  PUT so_test6
   {
      "settings" : {
         "number_of_shards" : 1,
         "number_of_replicas" : 1
      },
    "mappings": {
        "_doc":{
         "properties": {
           "anonymous": {"type": "boolean"},
