Illegal parameter exception in Url

The access URL appears: illegal character in scheme at index x

 

 

Use the get method to request data, and the parameters are after the url.

 

At first I thought it was a character encoding problem, but when I used utf-8, I found it was useless, and then some mobile phones would not report errors, and some mobile phones would;

 

public static void getRemoteJsonContent(final Map<String, String> param, final String url, final XValueCallback<String> callBack) throws Exception {
        String tempUrl = url;
        String jsonResult = "";
        //post request returns result
        DefaultHttpClient httpClient = new DefaultHttpClient();
        String paramStr = "";
        if (param != null) {
            for (String key : param.keySet()) {
//                paramStr += URLEncoder.encode(key, "UTF-8") + "=" + URLEncoder.encode(param.get(key), "UTF-8") + "&";
                paramStr += key + "=" + param.get(key) + "&";
            }
            if (!TextUtils.isEmpty(paramStr)) {
                tempUrl += "?" + paramStr;
            }
        }
        HttpGet method = new HttpGet(tempUrl.trim());
        HttpResponse result = httpClient.execute(method);
        /**Request sent successfully and get response**/
        if (result.getStatusLine().getStatusCode() == 200) {
            /**Read the json string data returned by the server**/
            jsonResult = EntityUtils.toString(result.getEntity(), "UTF-8");
            callBack.onSuccess(jsonResult);

        }

    }

 

 

here url is

String url = " http://testurl/xaeo/App/Api/app.php?name=13415654215&password=123456";

 

Looking closely, I found that there is an illegal character in it, that is, there is a space at the beginning; remove the space and it will be fine.
