# app_name 是阿里云 应用名称

response_body = JSON.load(response.body)

AliyunOpenSearch::Search.new("test", "test2", "test3").execute(params)

签名

你可以直接使用封装好的方法进行签名(文档读得好累)

  
  AliyunOpenSearch.request_method = "POST" # 默认是 GET, 大写

  # custom_params 的内容按照阿里云文档中的约定组织
  custom_params = {
    "action" => "push",
    "table_name" => "cars",
    "items" => [
      {
        "cmd": "update",
        "timestamp": 1_420_070_400_010,
        "fields": {
          "id": "121139313135",
          "styl_name": "aodi",
          "acquirer_id": "1"
        }
      }
    ].to_json
  }

  AliyunOpenSearch::Base.signature(
    AliyunOpenSearch::Base.basic_params.merge!(custom_params)
  )

检索

require "aliyun_open_search"

scan_service = AliyunOpenSearch::Scan.new("test")
scan_service = AliyunOpenSearch::Scan.new(["test", "test2"])

# AliyunOpenSearch::Scan.new(
#   ["test", "test2"], 

# 配置: 
#   query: "query=default:'abc'", # 默认所有
#   hit: "400", # 默认500, 范围 0~500
#   scroll: "1w", 
#   # 用来表示scroll请求的有效期，默认时间单位为ms, 也可以用1m表示1min
#   # 支持的时间单位包括：w=Week, d=Day, h=Hour, m=minute, s=second
#   format: "xml" # 默认 JSON
# )

scan_service.execute # 获取第一页
scan_service.result # 获取结果

# 下一页
scan_service.execute # 获取第二页
scan_service.result # 获取结果

下拉提示

require "aliyun_open_search"

# index_names 是阿里云应用名称，只能一个
# params 的内容按照阿里云文档中的约定组织

params =  {
            query: "test",
            suggest_name: "test_suggest",
            hit: 10
          }

AliyunOpenSearch::Suggest.new("test_suggest").execute(params)

测试

大部分时候, 我们并不需要真正的发出请求, 需要mock掉

# RSpec

# spec_helper.rb
config.before(:each) do
  @aliyun_open_search_syncs = allow_any_instance_of(AliyunOpenSearch::Syncs)
                              .to receive(:execute).and_return(true)
end

# 需要真正发出请求的时候
allow_any_instance_of(AliyunOpenSearch::Syncs).to receive(:execute).and_call_original
