我试图使用JSoup获取此URL
http://betatruebaonline.com/img/parte/330/CIGUEÑAL.JPG@H_301_3@
即使使用编码,我也有例外.
我不明白为什么编码错了.它回来了@H_301_3@
07001@H_301_3@
而是正确的@H_301_3@
07002@H_301_3@
private static void GetUrl()
{
try
{
String url = "http://betatruebaonline.com/img/parte/330/";
String encoded = URLEncoder.encode("CIGUEÑAL.JPG","UTF-8");
Response img = Jsoup
.connect(url + encoded)
.ignoreContentType(true)
.execute();
System.out.println(url);
System.out.println("PASSED");
}
catch(Exception e)
{
System.out.println("Error getting url");
System.out.println(e.getMessage());
}
}
解决方法
编码没有错,这里的问题是复合unicode&预组合的字符“Ñ”可以用两种方式显示,它们看起来相同但真的不同
precomposed unicode: Ñ -> %C3%91 composite unicode: N and ~ -> N%CC%83
我强调两个都是正确的,这取决于你想要的unicode类型：@H_301_3@
String normalize = Normalizer.normalize("Ñ",Normalizer.Form.NFD);
System.out.println(URLEncoder.encode("Ñ","UTF-8")); //%C3%91
System.out.println(URLEncoder.encode(normalize,"UTF-8")); //N%CC%83
