如何使用 elasticsearch-ruby gem 在 elasticsearch 中创建摄取管道

Question

我很挣扎，如何使用 elasticsearch-ruby 创建摄取附件管道 gem?

对于这次通话 -

PUT _ingest/pipeline/attachment
{
  "description" : "Extract attachment information",
  "processors" : [
    {
      "attachment" : {
        "field" : "data"
      }
    }
  ]
}

这是我得到的异常 -

2.2.5 :008 > client.ingest.put_pipeline({id: 'attachment', body: {description: "Extract attachment information", processors: { attachment: { field: 'document_content', indexed_chars: '-1', indexed_chars_field: "max_size"}}}})

Answer 1

错误状态

[processors] property isn't a list, but of type [java.util.HashMap]

在您的 REST 调用中您是正确的，因为 processors 是一个数组，但在您的 ruby 调用中您将其设为散列。

所以正确的做法是这样的：

 client.ingest.put_pipeline :id => 'attachment', :body => {description: "Extract attachment information", processors: [{ attachment: { field: 'document_content', indexed_chars: '-1', indexed_chars_field: "max_size"}}]}

Answer 2

这是正确的说法 -

client.ingest.put_pipeline :id => 'attachment', :body => {description: "Extract attachment information", processors: [{ attachment: { field: 'document_content', indexed_chars: '-1'}}]}
