Java特殊字符正则表达式

Question

我想在Java中使用正则表达式实现以下目标

String[] paramsToReplace = {"email", "address", "phone"};

//input URL string
String ip = "http://www.google.com?name=bob&email=okATtk.com&address=NYC&phone=007";

//output URL string
String op = "http://www.google.com?name=bob&email=&address=&phone=";

URL 可以包含特殊字符，例如 %

Answer 1

尝试以下表达式:(email=)[^&]+(将 email 替换为数组元素)并替换为组:input.replaceAll("("+ paramsToReplace[i] + "=)[^&]+", "$1");

 String input = "http://www.google.com?name=bob&email=okATtk.com&address=NYC&phone=007";
 String output = input;
 for( String param : paramsToReplace ) {
   output = output.replaceAll("("+ param + "=)[^&]+", "$1");
 }
