url 与 spring rest ful Z8A5DA52ED12644217D359E70C07A？

Question

I have an api write by spring restful. And I test with postman I call this api with param: content: 60 days` .

And when I catch it in backend through function below:

Result<List<T>> search(HttpServletRequest request, HttpServletResponse response,@RequestParam(name="search") String search) {
    Map<String, String[]> params = request.getParameterMap();
    return getService().resolve(params);
}

the value of param content is:

How can I fix it? Update:

Answer 1

The ' after days is a Unicode Character 'RIGHT SINGLE QUOTATION MARK' (U+2019) .

In UTF-8, that character is encoded as bytes E2 80 99 .

In ISO-8859-1, those bytes is â and two unprintable characters.

Conclusion: Postman is sending the content as UTF-8, but the server is reading it as ISO-8859-1.

Now you could try to find out why that discrepancy exists, but did you really intend to have that "Right Single Quotation Mark" in your content?
