Question

有没有办法改变这样的请求：

"Annotation text="President Obama called Wednesday on Congress to extend a tax break
for students included in last year's economic stimulus package, arguing that the policy
provides more generous assistance."
confidence="0.2" support="20" 
sparql="SELECT DISTINCT ?x WHERE { ?x a <http://dbpedia.org/ontology/OfficeHolder>; . 
?x ?related <http://dbpedia.org/resource/Chicago>; }" 
policy="whitelist"

进入这个？

我知道空格等于％20，但我不知道其他转换。有没有可以进行转换的Java库？

Answer 1

使用

URLEncoder.encode(textAfterQuestionMark);

Answer 2

encode的单参数版本标记为已弃用。为了更加确定方法将返回什么，最好指定一个编码字符集。

URLEncoder.encode( "foobar", "UTF-8" );

不同之处在于，对于单参数版本，“结果字符串可能会因平台的默认编码而异。”

将文本转换为URL
