微信公众号、APP微信支付
1、【基本配置】配置开发者服务器
2、右上角点击公众号名称，【功能设置】业务域名、JS接口安全域名
3、【接口权限】-【网页账号】设置域名
4、【微信支付】-【开发配置】-【支付授权目录】，配置你支付页面所在路径
比如我的路径是 http://XXXX/third_pay/weixin/wxpay_test.html；需要在此处配置 http://XXXX/third_pay/weixin
（如果是配置测试授权目录，还需要配置测试白名单，就是你要进行微信支付测试的帐号）
APP微信支付（需具备微信支付权限 - https://open.weixin.qq.com申请）
以下内容复制完，应该就能行了~
1、服务端方法
Controller
@RequestMapping("/initWechatConfig.xhtml")
public void initWechatConfig(HttpServletRequest request, HttpServletResponse response) throws Exception {
try {
String initType = getParams("initType");//request.getParameter("initType");
if (CommonUtil.isNull(initType)) {
throw new BizException(ErrorMsg.PARAMS_NULL);
}
if ("jsapi".equals(initType)) {//只有公众号微信支付才会调用该类型
HashMap respMap = new HashMap();
String initUrl = getParams("initUrl");//当前网页地址
if (CommonUtil.isNull(initUrl)) {
throw new BizException(ErrorMsg.PARAMS_NULL);
}
String noncestr = WxPayUtil.CreateNoncestr();
String timestamp = DateUtil.getTimestampWx();
String signature = null;
//获取
String appId = Constants.GZH_APPID;
Ticket ticket = getJsapiTicket(appId);
signature = SHA1Util.signForJsapiTicket(ticket.getTicket(), noncestr, timestamp, initUrl);
respMap.put("appId", appId);
respMap.put("timestamp", timestamp);
respMap.put("nonceStr", noncestr);
respMap.put("signature", signature);
writeSuccMsg(response, respMap);
} else if ("pay".equals(initType) || "appPay".equals(initType)) {//pay 网页端；appPay app端
//校验必要参数
String outTradeNo = getParams("outTradeNo");
//根据outTradeNo获取订单信息
//...
Double totalFee = 0.01;
String body = "body";
//校验必要参数
//根据支付类型生成预订单
String openId = getParams("openId");
if ("pay".equals(initType) && CommonUtil.isNull(openId)) {//网页端微信支付，必定有openId
throw new BizException(ErrorMsg.PARAMS_NULL);
}
String createIp = null//获取IP地址;
//封装信息后，初始化微信预订单
log.info("********************************************************************");
String appId = null;
String mchId = null;
String key = null;
String tradeType = null;
if ("pay".equals(initType)) {
tradeType = "JSAPI";
appId = Constants.GZH_APPID;
mchId = Constants.GZH_PAY_MCHID;
key = Constants.GZH_PAY_KEY;
} else if ("appPay".equals(initType)) {
tradeType = "APP";
appId = Constants.APP_APPID;
mchId = Constants.APP_PAY_MCHID;
key = Constants.APP_PAY_KEY;
}
String notify_url = Constants.UNIFIED_THIRD_PAY_NOTIFY_BROKER;
log.info("微信支付 - 回调地址:" + notify_url);
ThirdPayVo payVo = WxPayUtil.getPayElement(initType, appId, mchId, key, tradeType, outTradeNo, body, createIp, openId, totalFee, notify_url);
if (CommonUtil.isNull(payVo)) {
throw new BizException(ErrorMsg.PAY_INIT_FAIL);
}
writeSuccMsg(response, payVo);
} else {
throw new BizException(ErrorMsg.PARAMS_NULL);
}
} catch (Exception e) {
log.error("初始化微信配置 异常：", e);
writeErrorMsg(response, e.getMessage());
}
}
- 获取access_token、jsapi_ticket等就自己去看API了，很简单~
（获取access_token需要注意区分全局access_token和绑定openid的access_token）
writeSuccMsg
response.setCharacterEncoding("utf-8"); response.setContentType("text/json"); PrintWriter out = null; try { out = response.getWriter(); } catch (Exception e) { throw new RuntimeException(e); } String jsonstr = JSON.toJSONString(jsonEntity); out.print(jsonstr);

1、SHA1Util方法

上面的搞完了，服务端就完事了
接下来写网页
1、wxpay_test.html
2、common.js
/** * 获取参数 * @param paramsName * @returns */ function GetParams(paramsName) { var addr = window.location; if (addr != null && addr != '') { var reg = new RegExp("(^|&)" + paramsName + "=([^&]*)(&|$)"); var r = addr.search.substr(1).match(reg); if (r != null && r != '') { return decodeURI(r[2]); } else { null; } } else { return null; } } /** * 判断是否微信浏览器 * @returns {Boolean} */ function isWeiXin() { var ua = window.navigator.userAgent.toLowerCase(); if(ua.match(/MicroMessenger/i) == 'micromessenger'){ return true; } else { return false; } }3、weixin_common.js
