【问题描述】：

我已经在 docker 中安装了 Elasticsearch。我得到了这样的弹性搜索响应-

curl -XGET http://localhost:9200
{
    "name" : "NXgYHOl",
    "cluster_name" : "docker-cluster",
    "cluster_uuid" : "_na_",
    "version" : {
        "number" : "6.6.0",
        "build_flavor" : "default",
        "build_type" : "tar",
        "build_hash" : "a9861f4",
        "build_date" : "2019-01-24T11:27:09.439740Z",
        "build_snapshot" : false,
        "lucene_version" : "7.6.0",
        "minimum_wire_compatibility_version" : "5.6.0",
        "minimum_index_compatibility_version" : "5.0.0"
    },
    "tagline" : "You Know, for Search"
}

然后我在 rails 项目中配置它。

宝石文件

  gem 'elasticsearch-model'
  gem 'elasticsearch-rails'

应用程序/模型

require 'elasticsearch/model'

class Movie < ApplicationRecord
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
end
Movie.import(force: true)

config/initilizers/elasticsearch.rb

config = {
    host: "http://localhost:9200",
    transport_options: {
      request: { timeout: 5 }
    }
}

if File.exists?("config/elasticsearch.yml")
    config.merge!(YAML.load_file("config/elasticsearch.yml")[Rails.env].symbolize_keys)
end

Elasticsearch::Model.client = Elasticsearch::Client.new(config)

config/elasticsearch.yml

development: &default
    host: 'http://localhost:9200'
    transport_options:
      request:
        timeout: !!integer 300
test:
    <<: *default
production:
    host: 'http://localhost:9200'
  transport_options:
    request:
        timeout: !!integer 300

它给出了一个错误：

{"timeout"=>300, :proxy=>nil}:Hash 的未定义方法 `params_encoder'

我不明白这个错误。

【解决方案1】：

根据 ruby gem 的official docs，似乎transport_options 不是一个选项。

它确实提到了一个request_timeout 选项，它应该可以工作。因此，将您的 config/elasticsearch.yml 文件更改为以下内容：

development: &default
    host: 'http://localhost:9200'
    request_timeout: !!integer 300
test:
    <<: *default
production:
    host: 'http://localhost:9200'
    request_timeout: !!integer 300
