h5通过php微信支付宝支付,用H5调用支付微信公众号支付的解析
這篇文章主要為大家詳細介紹了微信公眾號支付H5調用支付,具有一定的參考價值，感興趣的小伙伴們可以參考一下
最近項目需要微信支付，然后看了下微信公眾號支付，雖然不難，但是細節還是需要注意的，用了大半天時間寫了個demo，并且完整的測試了一下支付流程，下面分享一下微信公眾號支付的經驗。
一、配置公眾號微信支付
需要我們配置微信公眾號支付地址和測試白名單。
比如：支付JS頁面的地址為 http://www.xxx.com/shop/pay/
那此處配置www.xxx.com/shop/pay/
二、開發流程
借用微信公眾號支付api(地址 http://pay.weixin.qq.com/wiki/doc/api/index.php?chapter=7_4)，我們需要開發的為紅色標記出的。如下：
三、向微信服務器端下訂單
調用統一下單接口，這樣就能獲取微信支付的prepay_id(http://pay.weixin.qq.com/wiki/doc/api/index.php?chapter=9_1)。
在調用該接口前有幾個字段是H5支付必須填寫的openid
3.1 獲取openid
可以通過網頁授權形式(http://mp.weixin.qq.com/wiki/17/c0f37d5704f0b64713d5d2c37b468d75.html)
在微信中發送如下鏈接
https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx520c15f417810387&redirect_uri=要跳轉的下訂單的url&response_type=code&scope=snsapi_base&state=123#wechat_redirect

四、微信H5調起支付
這個url需要后臺實現，其實現功能如下：
1、接受微信服務器端發送的支付結果。
2、向微信服務器發送支付結果
具體 參考微信aip(http://pay.weixin.qq.com/wiki/doc/api/index.php?chapter=9_7)
具體代碼如下：
4.1、授權向后臺發起生成統一下訂單頁面wxrepay.jsp
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
long t = System.currentTimeMillis();
%>
微信公眾號支付商品
- beacon 1分錢 1只
- 測試支付信息
確定購買
var code = urlparameter("code");
function reppay(){
ajaxUtil({}, mainpath+"/pay/wxprepay.shtml?code=" + code, repay);
}
function repay(response){
var info = response;
var url = "wxpay?appId=" + info.appId + "&timeStamp=" +info.timeStamp + "&nonceStr=" + info.nonceStr +
"&pg=" +info.pg + "&signType=" +info.signType + "&paySign=" +info.paySign;
window.location.href= url + "&showwxpaytitle=1";
}
首先是請求服務端wxprepay.shml接口，后臺向微信支付平臺獲取支付訂單信息，返回前臺，wxpay.jsp頁面
4.2、確認支付頁面
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
long t = System.currentTimeMillis();
%>

var paySign = urlparameter("paySign");
function onBridgeReady(){
WeixinJSBridge.invoke(

},
function(res){
if(res.err_msg == "get_brand_wcpay_request:ok" ) {
alert("支付成功");
} // 使用以上方式判斷前端返回,微信團隊鄭重提示：res.err_msg將在用戶支付成功后返回 ok，但并不保證它絕對可靠。
}
);
}
function pay(){
