Java IllegalArgumentException 索引处查询中存在非法字符

Question

我正在使用下面的代码，当我使用 http://stackoverflow.com/ 时效果很好。当我将其更改为 http://www.sitetest.com/query.php?request=how are you 我的应用程序抛出异常。它说:

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

里面有什么非法字符？我看不到它。

  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

似乎您有一些空白字符，这不是常规的
空格字符(十进制 32)。另外，它似乎没有进行 URL 编码。
