Hand in hand to teach you everbright pay

First, the payment flowchart

Second, process analysis

1. Page Ajax Access backstage (servlet or Resetful interface), send payment parameters to background

2. Back to front-end Ajax after the background is organized in clear and dark text by parameters

3. Front-end Ajax gets the plaintext and dark text of the background organization, as a parameter to access the payment gateway

4. After the successful payment, the light assembly visits the callback address set, the callback address in the verification, through the processing of orders to organize plaintext and ciphertext reply Everbright, payment completed

Third, the Code

1.view Layer

(1) Ajax access to backend resources

function Pay (Restfulurl, Formdata) {$.get (Requesturl+Formdata, function (data, status) {if(Data.status = =-1) {alert (data.msg); return; }            Else if(Data.status = = 1)                //window.open (payurl);//Open Form QQ Browser cannot open, the form of href can openWindow.location.href = data.msg.payurl+ "? Plain= "+data.msg.plain+" &signature= "+data.msg.signature; },        "JSON"    );});

3.service Layer (restful)

(1) Payservice.java
