Elasticsearch--文档管理

在Elasticsearch中，可以使用RESTful API进行文档的添加、获取、更新和删除。以下是使用Python和requests库进行文档管理的示例代码：

import requests
 
# 连接到Elasticsearch
es_url = 'http://localhost:9200'
index_name = 'my_index'
doc_type = 'my_type'  # 在Elasticsearch 7.0+中已废弃，这里仅为示例
 
# 添加文档
def create_document(id, document):
    url = f"{es_url}/{index_name}/{doc_type}/{id}"
    response = requests.post(url, json=document)
    print(response.json())
 
# 获取文档
def get_document(id):
    url = f"{es_url}/{index_name}/{doc_type}/{id}"
    response = requests.get(url)
    print(response.json())
 
# 更新文档
def update_document(id, document):
    url = f"{es_url}/{index_name}/{doc_type}/{id}"
    response = requests.put(url, json=document)
    print(response.json())
 
# 删除文档
def delete_document(id):
    url = f"{es_url}/{index_name}/{doc_type}/{id}"
    response = requests.delete(url)
    print(response.json())
 
# 示例文档
document = {
    "title": "Document 1",
    "content": "This is the first document"
}
 
# 使用示例
create_document('1', document)  # 添加文档
get_document('1')  # 获取文档
 
# 更新文档
document['content'] = "Updated content"
update_document('1', document)
 
# 删除文档
delete_document('1')

确保Elasticsearch服务器正在运行，并且localhost:9200可以连接到您的Elasticsearch实例。如果您的Elasticsearch设置不同，请相应地修改es_url变量。
