Java实现JsApi方式的微信支付
要使用JsApi进行微信支付，首先要从微信获得一个prepay_id，然后通过调用微信的jsapi完成支付，JS API的返回结果get_brand_wcpay_request:ok仅在用户成功完成支付时返回。由于前端交互复杂，get_brand_wcpay_request:cancel或者get_brand_wcpay_request:fail可以统一处理为用户遇到错误或者主动放弃，不必细化区分。示例代码如下：
function onBridgeReady(){
WeixinJSBridge.invoke(
'getBrandWCPayRequest', {
&appId& : &wx0ec43b&,
//公众号名称，由商户传入
&timeStamp&:& &,
//时间戳，自1970年以来的秒数
&nonceStr& : &e61463f8efacccfbbb444&, //随机串
&package& : &u802345jgfjsdfgsdg888&,
&signType& : &MD5&,
//微信签名方式:
&paySign& : &70EABB79628FBCAFADD89& //微信签名
function(res){
if(res.err_msg == &get_brand_wcpay_request:ok& ) {}
// 使用以上方式判断前端返回,微信团队郑重提示：res.err_msg将在用户支付成功后返回 ok，但并不保证它绝对可靠。
if (typeof WeixinJSBridge == &undefined&){
if( document.addEventListener ){
document.addEventListener('WeixinJSBridgeReady', onBridgeReady, false);
}else if (document.attachEvent){
document.attachEvent('WeixinJSBridgeReady', onBridgeReady);
document.attachEvent('onWeixinJSBridgeReady', onBridgeReady);
onBridgeReady();
以上传入的参数package，即为prepay_id
详细文档见：
下面讲的是获得参数来调用jsapi
我们调用JSAPI时，必须获得用户的openid，（trade_type=JSAPI，openid为必填参数。）
首先定义一个请求的对象：

因为有些参数为必填，有些参数为选填。而且sign要等所有参数传入之后才能计算的出，所以这里用了builder模式。关于builder模式。关于每个参数的定义，参考说明文档https://pay./wiki/doc/api/jsapi.php?chapter=9_1
我们选用httpclient进行网络传输。

return_code 和result_code都为SUCCESS的时候会返回我们需要的prepay_id。。。
然后在jsapi中使用他就可以了。。

关于报&getRrandWCPayRequest:fail_invalid appid 错误。
我的代码是基于ecshop开发的。一直报错。后来单狂拿出来，整理一个文件。将代码放在根目录的auth目录下。
支付目录是 /auth/wxpay.php (wxpay.php则是上面的代码)
授权目录则是 /auth/
（重点说明：授权目录填写是你支付的页面在哪个目录下就填当前目录下的目录。否则出错，不会弹出支付窗口。）
(经多次测试，如果在网站的根目录下，即使授权了，也报&getRrandWCPayRequest:fail_invalid appid 错误，解决方法则是：放在某目录下，再授权此目录,如果是根目录下，无法完成支付，必须要二级目录或三级等，不知这是微信硬性规定还是BUG)
关于返回页面，如下。放在当前支付目录下。respond.php
