I want to call a RestFul webservice in my android project. everything is Ok until I want to send special characters as a string to webservice.
at first I thought the problem is just with spaces and I replaced them with "%20". but I saw that these chars "\r\n,+,/,\,?,..." have problem too. I used URLEncoder.encodefor just that string( not whole URL) but it doesn't solve my problem for example it replaced spaces with '+' that caused error. or other exceptions for example when I have NewLine char in my string it gives me Bad Request - Invalid URL. and for each char I have some error like endpoint not found or Server Error in '/' Application.
URL url = new URL(reqUrl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");
right now I replaced each char manually. I want it to know why URLEncoder.encode doesn't do the right way and is there any other way to solve it?
Solution:
I found my problem, from this document :
Template String Syntax
A template has three parts: a path, an optional query, and an optional fragment.
I was sending my string parameter as a path part not optional query. when I send URLEncoder.encode(myStringParameter) as an optional query I didn't have any problem even with spaces.
