Introduction to the method of determining whether a string is garbled in java

There is a function in the project that will produce garbled code when submitted in GET mode in IE, but there are two entrances that will use the same piece of code

It cannot be directly transcoded, so To determine whether the passed value is garbled

can be verified in the following ways:

java.nio.charset.Charset.forName("GBK").newEncoder().canEncode("测试") //判断是不是GBK编码 即是否乱码
Copy after login
//使用request.getQueryString()获取通过URL传过来的值 有可能是乱码 如:q=青春
String s = request.getQueryString();   
if(s!=null){
if(!(java.nio.charset.Charset.forName("GBK").newEncoder().canEncode(s))){
try {
s = new String(request.getQueryString().getBytes("ISO-8859-1"),"UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
}
}
}
Copy after login
