java - Is it possible to use the content-type of a file to determine its filetype in Java?

Question

If so, how can I do that?

I'm trying to write a method that takes a content-type and returns whether it is a JSON file or not.

Answer 1

这是一个函数，它从 HTTP 请求中接收内容类型字符串，如果内容类型是 JSON 类型，则返回 TRUE，否则返回 FALSE。

public static boolean isJsonContentType(String contentType) {
    return (contentType.equals("application/json"));
}
