Question

我想使用我的Android应用程序解析一个php web服务，我创建了一个这样的url连接

InputStream stream = null ;
URL url = new URL(url);
HttpURLConnection conn;
conn=(HttpURLConnection)url.openConnection();
conn.setRequestMethod("POST");
conn.setReadTimeout(30000);
stream =conn.getInputStream();

在getInputStream之后，我使用pull解析器来解析xml数据，但我的问题是Web服务需要提交表单来获取xml数据。如何从我的java代码中单击此按钮？这是可能的还是我需要更改Web服务？

如果要从webservide读取数据，请执行以下步骤：在你的按钮的onclick听众

new urlConTask().execute() //use asynctask

在asynctask的doInBackground方法中

：

   @Override
        protected String doInBackground(String... params) {

            String url = ur url here;
            String response = "";
            try {
                 response = HttpConnect.sendGet(url);//sendGet is method defined in HttpConnect.java. Its a custom class

            } catch (Exception e) {
                e.printStackTrace();
            }

sendGetMethod：

   public static String  sendGet(String url) throws Exception {



        URL obj = new URL(url);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();

        // optional default is GET
        con.setRequestMethod("GET");

        //add request header

        int responseCode = con.getResponseCode();
        System.out.println("\nSending 'GET' request to URL : " + url);
        System.out.println("Response Code : " + responseCode);

        BufferedReader in = new BufferedReader(
                new InputStreamReader(con.getInputStream()));
        String inputLine;
        StringBuffer response = new StringBuffer();

        while ((inputLine = in.readLine()) != null) {
            response.append(inputLine);
        }
        in.close();

        //print result
        return response.toString(); //this is your response

    }

Answer 2

您的应用无法“点击”提交按钮。你说提交按钮提交了所有表格。您的应用应该执行提交按钮触发的请求。

Answer 3

我必须更改Web服务并使其获得GET和POST，然后我必须将我的代码放入

conn.setRequestMethod("GET");

android使用HttpURLConnection请求一个php web服务并提交php表单
