从Java播放框架向Solr发送HTTP请求时出现URI语法异常

Question

当我使用java中的WS-url（）的API播放框架发出HTTP请求时，会得到URISyntaxException。下面是异常的堆栈跟踪。

你能帮我解决这个问题吗？

Answer 1

这似乎不是Solr问题：

引起原因：java.net.URISyntaxException：索引419处的查询中存在非法字符：http://solrUrl.com/solr/catalog/select?facet=true&fl=标识符_ntk，catgroup_id，。。。。。

在java.net.URI$Parser.fail（URI.java:2810）~[na:1.6.0_65]位于java.net.URI$Parser.checkChars（URI.java:2983）~[na:1.6.0_65]在java.net.URI$Parser.parseHierarchive（URI.java:3073）~[na:1.6.0_65]

看起来URL在游戏方面可能是错误的。索引似乎指向最后一个或最后一个字符后的一个字符。我会在打开URL之前打印它，看看里面是否有什么有趣的东西。比如在URL的末尾有一个错误的换行符或类似的东西。
