solr，太阳黑子，错误请求，非法字符 [英] solr, sunspot, bad request, illegal character

问题描述

我正在将太阳黑子搜索引入我的项目.我只通过名称字段搜索就得到了一个 POC.当我引入描述字段并重新索引已售出时，我收到以下错误.

I am introducing sunspot search into my project. I got a POC by just searching by the name field. When I introduced the description field and reindexed sold I get the following error.

** Invoke sunspot:reindex (first_time)

我假设坏字符是你可以在底部看到.那散落在很多描述中.我什至不确定那是什么字符.

I assuming that the bad char is that you can see at the bottom. that is littered in a lot of the descriptions. I'm not even sure what char that is.

我该怎么做才能让 solr 忽略它或清理数据，以便 sell 可以处理它.

What can I do to get solr to ignore it or clean the data so that sold can handle it.

谢谢

推荐答案

将以下内容放入初始化程序中以自动清除任何 UTF8 控制字符的太阳黑子调用:

Put the following in an initializer to automatically clean sunspot calls of any UTF8 control characters:

# config/initializers/sunspot.rb
module Sunspot
  # 
  # DataExtractors present an internal API for the indexer to use to extract
  # field values from models for indexing. They must implement the #value_for
  # method, which takes an object and returns the value extracted from it.
  #
  module DataExtractor #:nodoc: all
    # 
    # AttributeExtractors extract data by simply calling a method on the block.
    #
    class AttributeExtractor
      def initialize(attribute_name)
        @attribute_name = attribute_name
      end

      def value_for(object)
        Filter.new( object.send(@attribute_name) ).value
      end
    end

    # 
    # BlockExtractors extract data by evaluating a block in the context of the
    # object instance, or if the block takes an argument, by passing the object
    # as the argument to the block. Either way, the return value of the block is
    # the value returned by the extractor.
    #
    class BlockExtractor
      def initialize(&block)
        @block = block
      end

      def value_for(object)
        Filter.new( Util.instance_eval_or_call(object, &@block) ).value
      end
    end

    # 
    # Constant data extractors simply return the same value for every object.
    #
    class Constant
      def initialize(value)
        @value = value
      end

      def value_for(object)
        Filter.new(@value).value
      end
    end

    # 
    # A Filter to allow easy value cleaning
    #
    class Filter
      def initialize(value)
        @value = value
      end
      def value
        strip_control_characters @value
      end
      def strip_control_characters(value)
        return value unless value.is_a? String

        value.chars.inject("") do |str, char|
          unless char.ascii_only? and (char.ord < 32 or char.ord == 127)
            str << char
          end
          str
        end

      end
    end

  end
end
