的Rails：geokit 「不兼容的字符編碼：UTF-8和ASCII-8BIT」

Question

我只想用geokit寶石與俄語字符，如以下（從鐵軌控制檯測試）：

Geokit::Geocoders::GoogleGeocoder.geocode 'минск' 

但獲得下錯誤：

Encoding::CompatibilityError: incompatible character encodings: UTF-8 and ASCII-8BIT 
     from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/geokit-1.6.5/lib/geokit/geocoders.rb:464:in `do_geocode' 
     from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/geokit-1.6.5/lib/geokit/geocoders.rb:129:in `geocode' 
     from (irb):16 
     from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/railties-3.2.1/lib/rails/commands/console.rb:47:in `start' 
     from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/railties-3.2.1/lib/rails/commands/console.rb:8:in `start' 
     from /usr/share/ruby-rvm/gems/ruby-1.9.3-p125/gems/railties-3.2.1/lib/rails/commands.rb:41:in `<top (required)>' 
     from script/rails:6:in `require' 
     from script/rails:6:in `<main>' 

下一個可能的解決方案不幫：

Geokit::Geocoders::GoogleGeocoder.geocode 'минск'.force_encoding('UTF-8') 
Geokit::Geocoders::GoogleGeocoder.geocode(CGI.escape('Минск')) 

#in config/environment.rb 
Encoding.default_external = Encoding::UTF_8 
Encoding.default_internal = Encoding::UTF_8 

有什麼可以幫到 解決這個問題？ 我有與google-places寶石相同的問題。

Answer 1

這裏的問題是記錄器。

https://github.com/imajes/geokit-gem/blob/master/lib/geokit/services/google3.rb#L49

在這條線就加入UTF-8 address字符串和ASCII json響應。修復將在此行之前添加以下代碼：

json.force_encoding('utf-8') if json.respond_to?(:force_encoding) 

您可以這樣做併發送拉取請求。剛剛爲Nominatim geocoder做了同樣的事情。
