Use HttpGet with illegal characters in the URL
Solution 1
http://java.sun.com/javase/6/docs/api/java/net/URLEncoder.html
Specifically:
String safeUrl = URLEncoder.encode("domain.com/service/{username}", "UTF-8");
Solution 2
we shouldn't use URLEncoder.encode for address part of URL because it wrongly changes your http://domain.com/{username} to http%3A%2F%2Fdomain.com%2{username} and you should know it will replace all spaces with '+' that it was better to me to replace them with "%20".
Here this function encodes only last part of your URL which is {username} or file name or anything that may have illegal characters.
String safeUrl(String inUrl)
{
int fileInd = inUrl.lastIndexOf('/') + 1;
String addr = inUrl.substring(0, fileInd);
String fileName = inUrl.substring(fileInd);
String outUrl=null;
try {
outUrl = addr + URLEncoder.encode(fileName, "UTF-8");
outUrl = outUrl.replace("+", "%20");
} catch (UnsupportedEncodingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return outUrl;
}
Solution 3
This question is old but it helped me and I just wanted to add for anyone who might come by that I fixed this issue on my app with a variation of Mike's reply.
String safeUrl = "domain.com/service/" + URLEncoder.encode("{username}", "UTF-8");
I found that encoding just the relevant parts worked, where attempting to encode the entire url caused an error for me.

I am trying to use
DefaultHttpClient
andHttpGet
to make a request to a web service. Unfortunately the web service URL contains illegal characters such as { (ex: domain.com/service/{username}). It's obvious that the web service naming isn't well written but I can't change it.When I do
HttpGet(url)
, I get that I have an illegal character in the url (that is { and }). If I encode the URL before that, there is no error but the request goes to a different URL where there is nothing.The url, although has illegal characters, works from the browser but the
HttpGet
implementation doesn't let me use it. What should I do or use instead to avoid this problem? -
