java - makeHttpRequest 中的换行符

Question

我收到java.lang.IllegalStateException:目标主机不得为空，或在参数中设置错误。进行 makeHttpRequest 时是新行字符，还是我在这里的路径不正确？代码:

        String url = "http://www.<myDomain>.co.za/insertTeamResultwithCode.php?Code="+code+
                "&Section="+section+
                "&Gender="+gender+
                "&WinningTeam="+newResult.getWinningTeam()+
                "&LosingTeam="+newResult.getLosingTeam()+
                "&FixtureD="+newResult.getDate()+
                "&FixtureT="+newResult.getTime()+
                "&Venue="+newResult.getVenue()+
                "&Court="+newResult.getCourt()+
                "&Texts="+newResult.getText();

        try 
        {
            String encodedUrl = URLEncoder.encode(url, "UTF-8");

            JSONParser jParser = new JSONParser();
            JSONObject json = jParser.makeHttpRequest(encodedUrl, "GET", isSuccessfull);

            try
            {
                boolean success = (json.getBoolean("isValid"));
                DisplayToast(success);
            }
            catch (JSONException d)
            {
                d.printStackTrace();
            }
        }
        catch (UnsupportedEncodingException e) 
        {
            e.printStackTrace();
        }

和 logcat 错误:

Answer 1

您不应该对完整的 URL 进行编码，因为它还会对主机部分进行编码，如下所示:

http%3A%2F%2Fwww.%3CmyDomain%3E.co.za%2FinsertTeamResultwithCode.php

这将失败，因为它无法解析此网址。

您应该仅对传递到此 URL 的参数进行编码。
