從Java播放框架向Solr發送HTTP請求時發生URISyntax異常

Question

當我使用java中的框架的WS.url（）API發出HTTP請求時，我收到了URISyntaxException。 下面是excetption的堆棧軌跡。

你能幫我解決嗎？

Answer 1

這似乎並不成爲一個問題的Solr：

產生的原因：java.net.URISyntaxException：在指數419查詢非法字符： http://solrUrl.com/solr/catalog/select?facet=true&fl=identifier_ntk,catgroup_id，.....

在java.net.URI $ Parser.fail（URI.java:2810）〜[na：1.6.0_65] at java.net.URI $ Parser.checkChars（URI.java:2983）〜[na：1.6.0_65] at java.net.URI $ Parser.parseHierarchical（URI.java:3073）〜[na：1.6.0_65]

看起來網址可能在播放方面有誤。該指數似乎指向最後一個或最後一個字符。在打開它之前，我會打印該URL，看看它裏面是否有什麼有趣的東西。就像在URL末尾有一個錯誤的換行符或類似的東西。
