支付处理集成的android [英] Payment processing Integration android

问题描述

我做我的第一个应用程序。现在我需要使用自定义浏览器payu一体化整合应用。我没有关于如何做这方面的知识。我搜索了这一点，但我失败了。请任何一个建议我还是给我提供链接的这种集成。预先感谢您。

I am doing my first application. Now i need to integrate payu integration in app using custom browser. i don't have knowledge on how to do this. I searched for this, but i failed. please any one suggest me or provide me links for this integration. thank you in advance.

推荐答案

虽然我只好从自己至少尝试一次，有很多可用反正这是payu在app.It整合完整的解决方案做题很简单

Although u have to try at least once from yourself there are lot of SO questions available anyways this is complete solution to integrate payu in your app.It is very simple.

首先定义的变量喜欢这样的：

First define your variables likes this:

String hash,hashSequence;
String post_Data;
String merchant_key="your key";
String salt="your salt";
String surl = "your surl"; 
String furl = "your furl";
String productinfo = "your product info or you can put anything here";
String txnid ="";
String amount;
Handler mHandler = new Handler();
String firstname, email,phone;
WebView webView ;

定义值后您的CreateView的应该是这样的：

After defining values your on createview should be like this:

@SuppressLint("JavascriptInterface")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.web_view);

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

        String hashSequence1 = merchant_key + "|" + txnid + "|" + amount + "|" + productinfo + "|" +
                               firstname+  "|" + email + "|||||||||||" + salt;

        hash=hashCal("SHA-512",hashSequence1);

        webView.setWebViewClient(new WebViewClient() {


            @Override
            public void onReceivedError(WebView view, int errorCode,
                                        String description, String failingUrl) {
                // TODO Auto-generated method stub
                System.out.println(">>>>>>>>>>>>>>onReceivedError>>>>>>>>>>>>>>>>>>");
                Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onReceivedSslError(WebView view,
                                           SslErrorHandler handler, SslError error) {
                // TODO Auto-generated method stub
                System.out.println(">>>>>>>>>>>>>>onReceivedSslError>>>>>>>>>>>>>>>>>>");
                Toast.makeText(activity, "SslError! " + error, Toast.LENGTH_SHORT).show();
                handler.proceed();
            }

            @Override
            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                // TODO Auto-generated method stub
                System.out.println(">>>>>>>>>>>>>>shouldOverrideUrlLoading>>>>>>>>>>>>>>>>>>");
                return true;

            }

            @Override
            public void onPageFinished(WebView view, String url) {
                // TODO Auto-generated method stub
                System.out.println(">>>>>>>>>>>>>>onPageFinished>>>>>>>>>>>>>>>>>>");

                super.onPageFinished(view, url);

            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
                System.out.println(">>>>>>>>>>>>>>onPageStarted>>>>>>>>>>>>>>>>>>");
            }
        });


        webView.setVisibility(View.VISIBLE);
        webView.getSettings().setBuiltInZoomControls(true);
        webView.getSettings().setCacheMode(2);
        webView.getSettings().setDomStorageEnabled(true);
        webView.clearHistory();
        webView.clearCache(true);
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setSupportZoom(true);
        webView.getSettings().setUseWideViewPort(true);
        webView.getSettings().setLoadWithOverviewMode(true);

        webView.addJavascriptInterface(new PayUJavaScriptInterface(this), "PayUMoney");

         post_Data = "hash="+hash+"&key="+merchant_key+"&txnid="+txnid+"&amount="+amount+
                "&productinfo="+productinfo+"&firstname="+firstname+ "&email="+email+"&phone="+phone+
                "&surl="+surl+"&furl="+ furl+ "&service_provider="+ "payu_paisa";

        webView.postUrl("https://secure.payu.in/_payment", EncodingUtils.getBytes(post_Data, "base64"));


    }

PayUJavaScriptInterface方式：

PayUJavaScriptInterface method:

    public class PayUJavaScriptInterface {
        Context mContext;

        /** Instantiate the interface and set the context */
        PayUJavaScriptInterface(Context c) {
            mContext = c;
        }


        public void success(long id, final String paymentId) {

            mHandler.post(new Runnable() {

                public void run() {

                    mHandler = null;

                    Intent intent = new Intent(PayMentGateWay.this, BoutiqueActivity.class);

                    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

                    intent.putExtra("result", "success");

                    intent.putExtra("paymentId", paymentId);

                    startActivity(intent);

                    finish();

                }

            });

        }

    }

此方法计算哈希值：

Calculate hash from this method:

    public String hashCal(String type,String str){
        byte[] hashseq=str.getBytes();
        StringBuffer hexString = new StringBuffer();
        try{
            MessageDigest algorithm = MessageDigest.getInstance(type);
            algorithm.reset();
            algorithm.update(hashseq);
            byte messageDigest[] = algorithm.digest();



            for (int i=0;i<messageDigest.length;i++) {
                String hex=Integer.toHexString(0xFF & messageDigest[i]);
                if(hex.length()==1) hexString.append("0");
                hexString.append(hex);
            }

        }catch(NoSuchAlgorithmException nsae){ }

        return hexString.toString();


    }

}

这就是它。
