汉字编码问题- Heroku

Question

我有一个使用Jieba for JRuby gem对中文句子进行标记化的小型JRuby Sinatra应用程序。

在我的本地机器上运行应用程序时，我没有任何编码问题：

curl --data "text=Ruby China，对！经是国内最权威的 Ruby 社区，拥有国内所有资深的 Ruby 工程师。&key=myKey" http://localhost:9292
# => ["Ruby", "China", "经是", "国内", "权威", "社区", "拥有", "所有", "资深", "工程师"]

然而，当我将应用程序推送到Heroku时，我遇到了编码问题：

curl --data "text=Ruby China，对！经是国内最权威的 Ruby 社区，拥有国内所有资深的 Ruby 工程师。&key=XWtrws324FGH675BV" http://secure-wildwood-3084.herokuapp.com
# => ["\"Ruby\", \"China\", \"  \", \" 。\""]

我尝试强制将编码转换为UTF-8 .force_encoding("utf-8")格式，但仍然有问题。我还尝试将Heroku上的LANG配置变量设置为LANG: zh_CN.UTF-8，但这没有什么区别。

我用来部署应用程序的方法是在README中。这是将应用推送到Heroku时的输出：

Answer 1

看一下输出/项目，它似乎使用了相当旧的JRuby片段，在这种情况下，最重要的是JRuby版本(您可能在本地有一个不同的版本)：1.6.7 https://github.com/diasks2/jieba-heroku/blob/master/pom.xml#L14

我将把它带到JRuby 1.7.16，并从以下输出中捆绑更新其他内容：

[INFO] Installing json 1.8.0
[INFO] Installing rack 1.4.1
[INFO] Installing rack-protection 1.2.0

[INFO] Installing sinatra 1.3.2
