用URL制作歌曲名称

Question

我有一个网址，我希望它看起来像这样：

Action Manatee - Action

http://xxxxxx.com/songs2/Music%20Promotion/Stream/Action%20Manatee%20-%20Action.mp3

修剪到“Stream /”之后的位置的语法是什么，并创建％20所在的空格。我也想修剪.mp3

Answer 1

嗯，对于那个特例，我会根据'/'字符拆分字符串然后修剪最后''后面的文字。字符。最后，将“％20”替换为“”。这应该留给你想要的字符串

测试

String initial = "http://xxxxxx.com/songs2/Music%20Promotion/Stream/Action%20Manatee%20-%20Action.mp3";

String[] split = initial.split("/");

String output = split[split.length-1];

int length = output.lastIndexOf('.');
output = output.substring(0, length);
output = output.replace("%20", " ");

Answer 2

您可以使用split()和replace(）方法来实现此目的，这里有两种方法：

使用正斜杠将您的字符串拆开：

string yourUrl = [URL Listed];

//Breaks your URL into sections on slashes
string[] sections = yourUrl.split("\/"); 

//Grabs the last section after the slashes, and replaces the %20 with spaces
string newString = sections[sectiongs.length-1].replace("%20"," ");

在Stream /部分分割您的字符串：（如果您可以保证它将采用该格式，则仅使用此内容）

string yourUrl = [URL Listed];

//This will get everything after Stream (your song name)
string newString = yourUrl.split("Stream\/")[1]; 

//Replaces your %20s with spaces
newString = newString.replace("%20"," ");

Answer 3

String urlParts[] = URL.split("\/");
String urlLast = urlParts[length-1];
String nameDotMp = urlLast.replaceAll("%20");
String name = nameDotMp.substring(0,nameDotMp.length-5);

Answer 4

URL songURL = new URL("yourpath/filename");
String filename = songURL.getFile();
