我收到一个错误。

错误：

"{"error":{"root_cause":[{"type":"parse_exception","reason":"无法将内容解析到映射"}],"type":"parse_exception","reason" :"无法将内容解析为映射","caused_by":{"type":"json_parse_exception","reason":"意外字符 ('s' (代码 115)): 期望用双引号来开始字段名称\ n 在 [来源：org.elasticsearch.transport.netty4.ByteBufStreamInput@38a4cd00; line: 2, column: 3]"}},"status":400}" 尝试创建索引时出错

代码：

【解决方案1】：

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"},
           "content_text_form": {"type": "text"},
