从 Azure Blob 存储和 ADLS Gen2 创建 Blob 知识源

• 必需Azure.Search.Documents 包：

• 所需的 azure-search-documents 包：

• 所需的 REST API 版本：

  • 对于预览功能： Search Service 2025-11-01-preview

知识来源是顶级可重用对象。 了解现有知识源有助于重复使用或命名新对象。

运行以下代码，按名称和类型列出知识源。

// List knowledge sources by name and type
using Azure.Search.Documents.Indexes;

var indexClient = new SearchIndexClient(new Uri(searchEndpoint), credential);
var knowledgeSources = indexClient.GetKnowledgeSourcesAsync();

Console.WriteLine("Knowledge Sources:");

await foreach (var ks in knowledgeSources)
{
    Console.WriteLine($"  Name: {ks.Name}, Type: {ks.GetType().Name}");
}

还可以按名称返回单个知识来源以查看其 JSON 定义。

using Azure.Search.Documents.Indexes;
using System.Text.Json;

var indexClient = new SearchIndexClient(new Uri(searchEndpoint), credential);

// Specify the knowledge source name to retrieve
string ksNameToGet = "earth-knowledge-source";

// Get its definition
var knowledgeSourceResponse = await indexClient.GetKnowledgeSourceAsync(ksNameToGet);
var ks = knowledgeSourceResponse.Value;

// Serialize to JSON for display
var jsonOptions = new JsonSerializerOptions 
{ 
    WriteIndented = true,
    DefaultIgnoreCondition = System.Text.Json.Serialization.JsonIgnoreCondition.Never
};
Console.WriteLine(JsonSerializer.Serialize(ks, ks.GetType(), jsonOptions));

知识来源是顶级可重用对象。 了解现有知识源有助于重复使用或命名新对象。

运行以下代码，按名称和类型列出知识源。

# List knowledge sources by name and type
import requests
import json

endpoint = "{search_url}/knowledgesources"
params = {"api-version": "2025-11-01-preview", "$select": "name, kind"}
headers = {"api-key": "{api_key}"}

response = requests.get(endpoint, params = params, headers = headers)
print(json.dumps(response.json(), indent = 2))

还可以按名称返回单个知识来源以查看其 JSON 定义。

# Get a knowledge source definition
import requests
import json

endpoint = "{search_url}/knowledgesources/{knowledge_source_name}"
params = {"api-version": "2025-11-01-preview"}
headers = {"api-key": "{api_key}"}

response = requests.get(endpoint, params = params, headers = headers)
print(json.dumps(response.json(), indent = 2))

知识来源是顶级可重用对象。 了解现有知识源有助于重复使用或命名新对象。

使用 知识源 - 获取（REST API） 按名称和类型列出知识源。

### List knowledge sources by name and type
GET {{search-url}}/knowledgesources?api-version=2025-11-01-preview&$select=name,kind
