Java IllegalArgumentException索引查询中的非法字符

Question

I'm using the code below, which works fine when I use http://stackoverflow.com/ . When I change it to http://www.sitetest.com/query.php?request=how are you My app throws an exception. It says:

Caused by: java.lang.IllegalArgumentException: Illegal character in query at index 46: http://www.sitetest.com/query.php?request=how %20are%20you?

What is the Illegal Character in there? I can't spot it.

  AsyncTask<String, String, String> result = new RequestTask().execute("http://www.sitetest.com/query.php?request=how are you"); 
        try { 
            this.textToSpeech(result.get().trim());
        } catch (InterruptedException e) { 
            //e.printStackTrace();
            Toast.makeText(this, "Interrupted",
                    Toast.LENGTH_LONG).show();
        } catch (ExecutionException e) { 
            Toast.makeText(this, e.getMessage(),
                    Toast.LENGTH_LONG).show();
            //e.printStackTrace();
        }

Answer 1

Seems you have some whitespace character there which is not the regular
space character (decimal 32). Also, it seems it is not URL encoded.

Answer 2

You should have inside the execute sth like:

urlencode('http://www.sitetest.com/query.php?request=how are you')

So, complete code on that line:

AsyncTask<String, String, String> result = new RequestTask().execute(urlencode('http://www.sitetest.com/query.php?request=how are you'));

My source:

PHP URL Encoding / Decoding

Side note:

I don't have a php environment installed on my machine right now, the verifying of that function needs to be made by you. That's what I found.
