[小记]JAVA对URL中的字符串处理(分割，转码)

public static void main(String[] args) {
//原始URL: http://localhost:9000/export/export?docids=AAwAADBYubCTAAAAb%2FPP,AAwAADBYubCTAAAAb7wE,AAwAADBYubCTAAAAb%2BHa,AAwAADBYubCTAAAAb%2BIF,AAwAADBYubCTAAAAb8aT,AAwAADBYubCTAAAAb8ae String docids = "AAwAADBYubCTAAAAb%2FPP,AAwAADBYubCTAAAAb7wE,AAwAADBYubCTAAAAb%2BHa,AAwAADBYubCTAAAAb%2BIF,AAwAADBYubCTAAAAb8aT,AAwAADBYubCTAAAAb8ae";
String[] doc_id = docids.split(","); //逗号进行分割成数组
int i = 0;
for(String docId:doc_id){
if(docId.contains("%")) {  //判断是否存在字符串%
try {
String s = java.net.URLDecoder.decode(docId, "utf-8");   //存在进行转码
doc_id[i] = new String(s);                                //数组元素赋值
System.out.println(s);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
i++;
}
System.out.print(doc_id.toString());
}
