由PowerShell批量數據到ElasticSearch，但拋出異常

Question

當我通過PowerShell將數據導入ElasticSearch時，它總是拋出異常，任何人都可以幫助我？

代碼：

$a = "{'create':{'_index':'kuyu','_type':'test','_id':'4'}}`n{'title': 'this is a test', 'text': 'test', 'date': '2016-01-02'}".Replace("'","`"") 
Invoke-RestMethod -Uri http://localhost:9200/_bulk -Method POST -Body $a 

的例外是：

Invoke-RestMethod : {"error":{"root_cause":[{"type":"action_request_validation_exception","reason":"Validation Failed: 1: no requests added;"}],"type":"action_request_validation_exception","reason":"Validation Failed: 1: no requests added;"},"status":400} 
At line:1 char:1 
+ Invoke-RestMethod -Uri http://localhost:9200/_bulk -Method POST -Bo ...

我認爲你只是缺少在您的請求結束一個新行，試試這個：

$a = "{'create':{'_index':'kuyu','_type':'test','_id':'4'}}`n{'title': 'this is a test', 'text': 'test', 'date': '2016-01-02'}`n".Replace("'","`"") 
Invoke-RestMethod -Uri http://localhost:9200/_bulk -Method POST -Body $a
