微信公众号支付 js api java版本
提及来.微信支付真是一堆坑. 竟然官网都没有java版本的完整代码. 就算是php版本的.还都有错误.且先后各类版本.各类文档一大堆....不停的误导开发人员.javascript
花了一天半时间.总算实现了微信公众号支付.和pc端的微信扫码支付.其余不说了.直接给思路
php
本人作的是微信V3版本的微信支付.微信的官方文档中.提供的demo 只有一些工具类.这些类仍是颇有做用的.java
https://mp.weixin.qq.com/paymch/readtemplate?t=mp/business/course3_tmpl&lang=zh_CN 能够在这个链接中找到相应的java类.jquery
这里必定要注意.在官网填写的受权目录必定要写到三级目录.如:
git
个人回调地址是:http://111.111.111.111:1111/control/weixinPay_notify web
那么,官网填写都受权目录就是:http://111.111.111.111:1111/control/api
我试过.受权目录写到2级.是没用的.此处差评,第一个坑.数组
首先,定义各类微信支付所须要的参数
缓存
GzhConfig.java服务器
public static String APPID = "XXXXXXXXXXXX"; //受理商ID，身份标识 public static String MCHID = "XXXXXXXXXXXXxx"; //商户支付密钥Key。审核经过后，在微信发送的邮件中查看 public static String KEY = "XXXXXXXXXXXXXXXXX"; //JSAPI接口中获取openid，审核后在公众平台开启开发模式后可查看 public static String APPSECRET = "xxxxxxxxxxxxxx"; //重定向地址 public static String REDIRECT_URL = "http://XXXXXXXXXXXXXXXXXXX/callWeiXinPay"; //异步回调地址 public static String NOTIFY_URL = "http://XXXXXXXXXXXXXXXXXXXXXX/weixinPay_notify"; //web回调地址 public static String WEB_NOTIFY_URL = "http://XXXXXXXXXXXXXXXXXXXXXXXXX/weixinPay_notify";
而后.就是正式的开始代码了:
1.使用Oauth2.0受权.进行页面跳转,获取code .(code关系着后面获取openid.)
https://open.weixin.qq.com/connect/oauth2/authorize?appid=123456789&redirect_uri=http://111.111.111.111:1111/control/orderPay&response_type=code&scope=snsapi_base&state=456123456#wechat_redirect
此处.appid 这个在微信官网能够获取. 重定向地址. 就是获取code 后.跳转指向你的地址.这里能够是你的订单结算页面.response_type=code和scope=snsapi_base 都是固定格式. state 是传入传出.这个参数用户自定义为任何均可以,好比说订单id. 而后会和code 一块儿传递到你的重定向地址,如我上面写的重定向地址就是 orderPay连接.
2.在重定向到页面(http://111.111.111.111:1111/control/orderPay)的时候中间执行java方法(如获取openid 如执行微信统一下单接口,获取预支付ID.).处理各类参数.下面贴具体代码作说明.
GzhService.java
String code = request.getParameter("code");
String state = request.getParameter("state");
Debug.log("code-======"+code+"===========state======"+state);
String noncestr = Sha1Util.getNonceStr();//生成随机字符串
String timestamp = Sha1Util.getTimeStamp();//生成1970年到如今的秒数.
//state 能够传递你的订单号.而后根据订单号 查询付款金额.我就不详细写了.
String out_trade_no = state;//订单号
GenericValue orderHeader = delegator.findOne("OrderHeader", UtilMisc.toMap("orderId", out_trade_no),false);
String total_fee = String.valueOf(orderHeader.getBigDecimal("grandTotal").doubleValue()*100);
String order_price = total_fee.substring(0, total_fee.indexOf("."));//订单金额
//微信金额 以分为单位.这是第二坑.若是不注意.页面的报错.你基本看不出来.由于他提示系统升级,正在维护.扯淡.....
String product_name=out_trade_no;//订单名称
//获取jsapi_ticket.此参数是为了生成 js api 加载时候的签名用.必须.jsapi_ticket只会存在7200秒.而且有时间限制,(好像一年还只能调用两万次.因此必定要缓存.)这是第三坑.
//能够在java中模拟url请求.就能获取access_token 而后根据access_token 取得 jsapi_ticket,但必定要缓存起来..这个代码.我只提供获取.缓存大家本身处理.
//SendGET方法我会在后面放出
String tokenParam = "grant_type=client_credential&appid="+GzhConfig.APPID+"&secret="+GzhConfig.APPSECRET;
String tokenJsonStr = SendGET("https://api.weixin.qq.com/cgi-bin/token", tokenParam);
Map tokenMap = JSON.parseObject(tokenJsonStr);
//获取access_token
String access_token = (String)tokenMap.get("access_token");
String ticketParam = "access_token="+access_token+"&type=jsapi";
String ticketJsonStr = SendGET("https://api.weixin.qq.com/cgi-bin/ticket/getticket", ticketParam);
Map ticketMap = JSON.parseObject(ticketJsonStr);
//获取jsapi_ticket
String ticket = (String)ticketMap.get("ticket");
//下面就到了获取openid,这个表明用户id.
//获取openID
String openParam = "appid="+GzhConfig.APPID+"&secret="+GzhConfig.APPSECRET+"&code="+code+"&grant_type=authorization_code";
String openJsonStr = SendGET("https://api.weixin.qq.com/sns/oauth2/access_token", openParam);
Map openMap = JSON.parseObject(openJsonStr);
String openid = (String) openMap.get("openid");
RequestHandler reqHandler = new RequestHandler(request, response);
//初始化 RequestHandler 类能够在微信的文档中找到.还有相关工具类
reqHandler.init();
reqHandler.init(GzhConfig.APPID, GzhConfig.APPSECRET, GzhConfig.KEY, "");
//执行统一下单接口 得到预支付id
reqHandler.setParameter("appid",GzhConfig.APPID);
reqHandler.setParameter("mch_id", GzhConfig.MCHID); //商户号
reqHandler.setParameter("nonce_str", noncestr); //随机字符串
reqHandler.setParameter("body", product_name); //商品描述(必填.若是不填.也会提示系统升级.正在维护我艹.)
reqHandler.setParameter("out_trade_no", out_trade_no); //商家订单号
reqHandler.setParameter("total_fee", order_price); //商品金额,以分为单位
reqHandler.setParameter("spbill_create_ip",request.getRemoteAddr()); //用户的公网ip IpAddressUtil.getIpAddr(request)
//下面的notify_url是用户支付成功后为微信调用的action 异步回调.
reqHandler.setParameter("notify_url", GzhConfig.NOTIFY_URL);
reqHandler.setParameter("trade_type", "JSAPI");
//------------须要进行用户受权获取用户openid-------------
reqHandler.setParameter("openid", openid); //这个必填.
//这里只是在组装数据.还没到执行到统一下单接口.由于统一下单接口的数据传递格式是xml的.因此才须要组装.
String requestUrl = reqHandler.getRequestURL();
requestUrl 例子:
/*
<xml><appid>wx2421b1c4370ec43b</appid><attach>支付测试</attach><body>JSAPI支付测试</body><mch_id>10000100</mch_id><nonce_str>1add1a30ac87aa2db72f57a2375d8fec</nonce_str><notify_url>http://wxpay.weixin.qq.com/pub_v2/pay/notify.v2.php</notify_url><openid>oUpF8uMuAJO_M2pxb1Q9zNjWeS6o</openid><out_trade_no>1415659990</out_trade_no><spbill_create_ip>14.23.150.211</spbill_create_ip><total_fee>1</total_fee><trade_type>JSAPI</trade_type><sign>0CB01533B8C1EF103065174F50BCA001</sign></xml>
