【问题描述】：

由于 Azure 门户中的 bug，我需要使用 REST API 以编程方式创建 Azure 认知搜索数据源、索引和索引器。创建数据源或索引没有问题，但下面的 POST 请求返回以下错误。

    "error": 
        "code": "",
        "message": "The request is invalid. Details: dataSource : A resource without a type name was found, but no expected type was specified. To allow entries without type information, the expected type must also be specified when the model is specified.\r\n"
    

以下 POST 请求是在此 page 上找到的修改示例，其中变量替换为服务名称、管理密钥、数据源名称和目标索引名称的正确名称。

POST 请求（使用邮递员）

POST https://SERVICENAME.search.windows.net/indexers?api-version=2019-05-06
Content-Type: application/json
api-key: ADMINKEY


  "name" : "my-json-indexer",
  "dataSourceName" : "BLOBDATASOURCE",
  "targetIndexName" : "TARGETINDEX",
  "schedule" :  "interval" : "PT2H" ,
  "parameters" :  "configuration" :  "parsingMode" : "json"  

【参考方案1】：

似乎在您创建数据源时，没有提供 type 属性。

这是两个请求：

创建数据源

POST https://[service name].search.windows.net/datasources?api-version=2019-05-06
Content-Type: application/json
api-key: [admin key for Azure Cognitive Search]


    "name" : "my-blob-datasource",
    "type" : "azureblob",
    "credentials" :  "connectionString" : "DefaultEndpointsProtocol=https;AccountName=<account name>;AccountKey=<account key>;" ,
    "container" :  "name" : "my-container", "query" : "optional, my-folder" 
  

创建索引器

POST https://[service name].search.windows.net/indexers?api-version=2019-05-06
Content-Type: application/json
api-key: [admin key for Azure Cognitive Search]


  "name" : "my-json-indexer",
  "dataSourceName" : "my-blob-datasource",
  "targetIndexName" : "my-target-index",
  "schedule" :  "interval" : "PT2H" ,
  "parameters" :  "configuration" :  "parsingMode" : "json"  ,
  "fieldMappings" : [
     "sourceFieldName" : "/article/text", "targetFieldName" : "text" ,
     "sourceFieldName" : "/article/datePublished", "targetFieldName" : "date" ,
     "sourceFieldName" : "/article/tags", "targetFieldName" : "tags" 
    ]
