URLを使用してjsonを解析しようとしています。一時的な URL を使用して達成できますが、メイン ホストの URL を使用すると、json は html 値を返しますか?

仮URL

<string>XML内でJSON応答を取得しているため、最初にそのタグからJSONデータを取得する必要があります。

{"不動産"：{"マドゥライ"：[{"id"： "5"、 "カテゴリ"： "不動産"、 "タイプ"： "シルバー"、 "名前"： "ヒーラ"、 "バナー"： "www.glossymob.com/soli/MapMadurai/5_banner_laptop-computer.jpg"、 "logo"： "www.glossymob.com/soli/MapMadurai/5_logo_laptop-computer.jpg"、 "about"： "test"、 "contact "：" test "、" map "：{"lat_long_1 "：{"latitude "：" 10.00 "、" longitude "：" 9.50 "}}}]、" total "：1}}

解決：

parse()Webからデータを受け取ったら、電話してください。

例えば：

XMLParser parser = new XMLParser();
JSONArray jsonRes = parser.parse(response.getEntity().getContent());
// response is the HTTPResponse object

XMLParserクラスは次のとおりです。

public class XMLParser extends DefaultHandler {

    private static String ROOT_ELEMENT = "string";
    private StringBuffer data = new StringBuffer();

    private JSONArray jsonData;

    public XMLParser() {
    }

    public JSONArray parse(InputStream in) {
        try {
            SAXParser parser = SAXParserFactory.newInstance().newSAXParser();
            parser.parse(in, this);
        } catch (ParserConfigurationException e) {
            e.printStackTrace();
        } catch (SAXException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if(in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
        return jsonData;
    }

    @Override
    public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
        data.replace(0, data.length(), "");

        if (localName.equalsIgnoreCase(ROOT_ELEMENT)) {
            jsonData = new JSONArray();
        }
    }

    @Override
    public void characters(char[] ch, int start, int length) throws SAXException {
        data.append(ch, start, length);
    }

    @Override
    public void endElement(String uri, String localName, String qName) throws SAXException {

        if (localName.equalsIgnoreCase(ROOT_ELEMENT)){
            try {
                jsonData = new JSONArray(data.toString());
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }


    }

あなたの応答は:-

<string xmlns="http://tempuri.org/">
{"real estate":{"Madurai":[{"id":"5","category":"real estate","type":"Silver","name":"Heera","banner":"www.glossymob.com/soli/MapMadurai/5_banner_laptop-computer.jpg","logo":"www.glossymob.com/soli/MapMadurai/5_logo_laptop-computer.jpg","about":"test","contact":"test","map":{"lat_long_1":{"latitude":"10.00","longitude":"9.50"}}} ],"total":1} }
</string>

まず、次のように置き換える必要があります

responseString = responseString.replace("<string xmlns=\"http://tempuri.org/\">","");
responseString = responseString.replace("</string>","");

上記の行を置き換えた後、文字列を JSONObject に変換してください。

純粋な JSON ではありません。その中に XML タグがあります。XML のみを使用するか、JSON を使用します。

上部と下部の XML タグを削除して、JSON の解析を進めれば簡単です。
