你好朋友。 我正在学习Java。我想获得一些URL的部分内容。请看上面的网址,我想得到" x" url中的属性(粗体)如何得到" x = ......" ?
我使用了这段代码:
String link = text.substring(39, 734);
但如果url的长度不同,则代码不正确。 如何在上面的网址上获得确切的价值? 我希望在&strong; 之前从 x = 转到。

使用URI
类:
final URI uri = new URI(yourUrlHere);
final String query = uri.getQuery();
然后,您可以从query
。
此外,您可以执行大量其他检查,因为URI类有很多方法可以获取不同的组件等。有关详细信息,请参阅the javadoc。

String url = url1;
int start = url.indexOf("x=");
int end = url.indexOf("&nv_mid=");
String value = url.substring(start, end);
