java - What type of Charset URL encoding should this use?

Question

I have a rest api and when I enter a URL in the browser, part of the URL looks like this:

...where+%7B%0D%0A%3Fs+<http%3A%2F%2F...

which actually stands for

...where { ?s <http://...

Now, when I have to call the same URl through my JAVA code, I know of URLEncoder using which I am encoding the URL. When I use "UTF-8" format, the "<" in the URL is also encoded as %3C.

Is there any way of encoding such that the "<" and ">" are retained while other parts of the URL such as spaces and others are encoded properly.

Answer 1

“<”得到编码的原因是因为它不是合法的URI字符。它与字符编码无关。

如果服务器没有正确处理转义序列，那么它需要得到修复。

Answer 2

You can do

URLEncoder.encode(urlString).replace("%3C", "<")

Answer 3

URLEncoder.encode(url, "UTF-8").replaceAll("%3C", "<").replaceAll("%3E", ">");
