如何在Android中实现Telenor easypay API

我正在实现telenor easypay API，它由两个Web服务组成，第一个是我发布我的店铺id和其他信息，这些信息使我成功地使用Auth_令牌和postbackurl进行响应。当我将Auth令牌和postback url发布到下一个Web服务url

https://easypaystg.easypaisa.com.pk/easypay/Confirm.jsf

它将我重定向到easypaisa结帐屏幕，其中在easypay签出屏幕上显示以下错误

public class Payment_details extends AppCompatActivity {
    private WebView webView;
    String postData = null;
    private RelativeLayout mConfirm;
    String data;
    boolean isFirst = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.payment_details);
        mConfirm = (RelativeLayout) findViewById(R.id.pd_confirm);


        webView = (WebView) findViewById(R.id.pdwebView);

        data = "https://easypaystg.easypaisa.com.pk/easypay/Index.jsf";
        Log.e("data", data);


        try {


            postData = URLEncoder.encode("amount", "UTF-8")
                    + "=" + URLEncoder.encode("10", "UTF-8");

            postData += "&" + URLEncoder.encode("storeId", "UTF-8") + "="
                    + URLEncoder.encode("xxxx", "UTF-8");

            postData += "&" + URLEncoder.encode("postBackURL", "UTF-8")
                    + "=" + URLEncoder.encode("your post back url any url", "UTF-8");

            postData += "&" + URLEncoder.encode("orderRefNum", "UTF-8")
                    + "=" + URLEncoder.encode("1111", "UTF-8");

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        webView.setWebViewClient(new MyWebViewClient());
        WebSettings settings = webView.getSettings();
        settings.setJavaScriptEnabled(true);

        webView.postUrl(data, postData.getBytes());




    }

    private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);


            return true;
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            super.onPageFinished(view, url);

            Log.e("purl", url);
            if(isFirst) {
                isFirst = false;
                String[] ist = url.split("=");
                String[] snd = ist[1].split("&");
                String Token = snd[0];

                Log.e("token", Token);
                Log.e("posturl", ist[2]);
                secondredirect(Token, view);
            }

        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);




        }

        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
            handler.proceed();
        }

    }

    @Override
    public void onBackPressed() {
    }

   private void secondredirect(String token, WebView view){
       String sData = null;
       String sURL = "https://easypaystg.easypaisa.com.pk/easypay/Confirm.jsf";
       try {
           sData = URLEncoder.encode("auth_token", "UTF-8")
                   + "=" + URLEncoder.encode(token, "UTF-8");

           sData += "&" + URLEncoder.encode("postBackURL", "UTF-8") + "="
               + URLEncoder.encode("any url as a postback url", "UTF-8");
           view.postUrl(sURL, sData.getBytes());
       } catch (UnsupportedEncodingException e) {
           e.printStackTrace();
       }
   }

我已经解决了这个问题并实现了Telenor easypay API，神奇的是我们将在webview中完成所有事情。。。使用webview将数据发布到第一个URL，它将返回附加到URL的auth_令牌和postbackurl。。。然后将auth_令牌和postbackurl发布到webview中的第二个URL，它将成功地使您进入easypay签出屏幕

public class Payment_details extends AppCompatActivity {
    private WebView webView;
    String postData = null;
    private RelativeLayout mConfirm;
    String data;
    boolean isFirst = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.payment_details);
        mConfirm = (RelativeLayout) findViewById(R.id.pd_confirm);


        webView = (WebView) findViewById(R.id.pdwebView);

        data = "https://easypaystg.easypaisa.com.pk/easypay/Index.jsf";
        Log.e("data", data);


        try {


            postData = URLEncoder.encode("amount", "UTF-8")
                    + "=" + URLEncoder.encode("10", "UTF-8");

            postData += "&" + URLEncoder.encode("storeId", "UTF-8") + "="
                    + URLEncoder.encode("xxxx", "UTF-8");

            postData += "&" + URLEncoder.encode("postBackURL", "UTF-8")
                    + "=" + URLEncoder.encode("your post back url any url", "UTF-8");

            postData += "&" + URLEncoder.encode("orderRefNum", "UTF-8")
                    + "=" + URLEncoder.encode("1111", "UTF-8");

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
        webView.setWebViewClient(new MyWebViewClient());
        WebSettings settings = webView.getSettings();
        settings.setJavaScriptEnabled(true);

        webView.postUrl(data, postData.getBytes());




    }

    private class MyWebViewClient extends WebViewClient {
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            view.loadUrl(url);


            return true;
        }

        @Override

            super.onPageFinished(view, url);

            Log.e("purl", url);
            if(isFirst) {
                isFirst = false;
                String[] ist = url.split("=");
                String[] snd = ist[1].split("&");
                String Token = snd[0];

                Log.e("token", Token);
                Log.e("posturl", ist[2]);
                secondredirect(Token, view);
            }

        }

        @Override
        public void onPageStarted(WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);




        }

        @Override
        public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
            handler.proceed();
        }

    }

    @Override
    public void onBackPressed() {
    }

   private void secondredirect(String token, WebView view){
       String sData = null;
       String sURL = "https://easypaystg.easypaisa.com.pk/easypay/Confirm.jsf";
       try {
           sData = URLEncoder.encode("auth_token", "UTF-8")
                   + "=" + URLEncoder.encode(token, "UTF-8");

           sData += "&" + URLEncoder.encode("postBackURL", "UTF-8") + "="
               + URLEncoder.encode("any url as a postback url", "UTF-8");
           view.postUrl(sURL, sData.getBytes());
       } catch (UnsupportedEncodingException e) {

没有适合开发人员的文档和支持。只是一些过时的PDF文件。看起来他们对帮助开发者并不认真。
