紅寶石 - 微軟翻譯意外的標記錯誤

Question

我用下面的方法來從英語一個簡單的詞翻譯成俄語致電：

translate("hello")

這是我的方法：

def translate(text) 

    begin 

     uri = "http://api.microsofttranslator.com/V2/Ajax.svc/GetTranslations?appId=#{@appid}&text=#{text.strip}&from=en&to=ru&maxTranslations=1" 
     page = HTTParty.get(uri).body 
     show_info = JSON.parse(page) # this line throws the error 

    rescue 

     puts $! 

    end 

end 

JSON輸出：

{"From":"en","Translations":[{"Count":0,"MatchDegree":100,"MatchedOriginalText":"","Rating":5,"TranslatedText":"Привет"}]} 

錯誤：

unexpected token at '{"From":"en","Translations":[{"Count":0,"MatchDegree":100,"MatchedOriginalText":"","Rating":5,"TranslatedText":"Привет"}]}' 

不確定這是什麼意思unexpected token。這是我收到的唯一錯誤。不幸的是，我不能修改JSON輸出，因爲它是由API本身返回的。

UPDATE：

貌似API將返回一些非法字符（壞微軟）：

'´╗┐{"From":"en","Translations":[{"Count":0,"MatchDegree":0,"Matched OriginalText":"","Rating":5,"TranslatedText":"Hello"}]}' 

完整的錯誤：

C:/Ruby193/lib/ruby/1.9.1/json/common.rb:148:in `parse': 743: unexpected token at '´╗┐{"From":"en","Translations":[{"Count":0,"MatchDegree":0,"Matched 
OriginalText":"","Rating":5,"TranslatedText":"Hello"}]}' (JSON::ParserError) 
     from C:/Ruby193/lib/ruby/1.9.1/json/common.rb:148:in `parse' 
     from trans.rb:13:in `translate' 
     from trans.rb:17:in `<main>'

嘗試確保UTF-8編碼和剝離字符串中的任何領先BOM指標：

# encoding: UTF-8 
# ^-- Make sure this is on the first line! 

def translate(text) 
    begin 
    uri = "http://api.microsofttranslator.com/V2/Ajax.svc/GetTranslations?appId=#{@appid}&text=#{text.strip}&from=en&to=ru&maxTranslations=1" 
    page = HTTParty.get(uri).body 
    page.force_encoding("UTF-8").gsub!("\xEF\xBB\xBF", '') 
    show_info = JSON.parse(page) # this line throws the error 
    rescue 
     puts $! 
    end 
end
