我在苦苦挣扎，如何使用 elasticsearch-ruby gem 创建摄取附件管道？

对于这个电话 -

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

这是我得到的例外 -

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"}}}})

请展示你到目前为止所做的事情
@Val - 我已更新问题并正在寻找此请求的方法。
你试过client.ingest.put_pipeline :id => 'attachment', :body => {....}吗？
@Val，我已经尝试过你建议我的方法，但我遇到了一个例外。我已经更新了这个问题，但有例外。请看一看。
您没有正确粘贴正文。请参阅下面的答案

【解决方案1】：

错误状态

[processors] 属性不是列表，而是 [java.util.HashMap] 类型

在您的 REST 调用中，您认为它是正确的，因为 processors 是一个数组，但在您的 ruby 调用中，您将其设为哈希。

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"}}]}

【讨论】：

酷，很高兴它有帮助！
谢谢@Val，你知道吗，如何使用 elasticsearch ruby 在附件管道中使用文档？我没有找到任何方法。
随意创建另一个问题来描述您的问题。
我发布了一个新问题。请审查它。谢谢@Val

【解决方案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'}}]}
