Rest style

5.1 Introduction

RESTful is an architecture specification, constraints, and principles. An architecture that conforms to this specification is a RESTful architecture.

operating

method	url address	description
PUT	localhost:9100/index name/type name/document id	Create document (specify id)
POST	localhost:9100/index name/type name	Create document (random id)
POST	localhost:9100/index name/document type/document id/_update	Modify the document
DELETE	localhost:9100/index name/document type/document id	Delete document
GET	localhost:9100/index name/document type/document id	Query documents by document id
POST	localhost:9100/index name/document type/_search	Query all documents

5.2 Testing

• 1. Create an indexPUT /索引名/类型名/id
• The default is _doc

type of data

1. Basic data type

• String text, keyword
• Data type long, integer, short, byte, double, float, half_float, scaled_float
• Date
• Boolean
• Binary

1. Develop data types

Create rules

PUT /test2
{
    
    
  "mappings": {
    
    
    
    "properties": {
    
    
      "name": {
    
    
        "type": "text"
      },
      "age": {
    
    
        "type": "long"
      },
      "birthday": {
    
    
        "type": "date"
      }
    }
  }  
}

Output:

{
    
    
  "acknowledged" : true,
  "shards_acknowledged" : true,
  "index" : "test2"
}

If you do not specify a specific type, es will configure the type by default

View index

GET test2

• View es information

  get _cat/

modify

  1. 之前的办法：直接put
  2. 现在的办法：

 POST /test1/_doc/1/_update
  {
    
    
"doc": {
    
    
  "name": "庞世宗"
  }
  }

Delete index

DELETE test1
