HBuilder基础上调用支付宝App支付、微信支付App支付（PHP）

1.微信支付注意事项:

{"code":-100,"message":"[payment微信:-1]General errors"}

以上错误码-100是5+SDK的错误码，而-1为微信支付SDK的错误码，对应的微信的错误类型为：签名错误、未注册APPID、项目设置APPID不正确、注册的APPID与设置的不匹配、其他异常等。
根据错误提示我们逐步排除。

登记的包名或签名错误

核对微信后台登记的应用包名以及应用签名是否有误，登记的签名需要和签名工具获取到的一致，更新这些信息并非马上生效，可以等一段时间再测试。另外需要确保应用已经通过审核，并获得支付权限。

APPID错误

核对项目中manifest.json文件中填写的微信支付的AppID是否和平台上的一致。

付款信息计算错误

核对后端代码，查验统一下单和调起支付接口的逻辑是否有误，并确保两次签名生成算法一致。

H5+接口调用错误

接口plus.payment.request调用时传入的支付信息是字符串类型，如:官方返回数据地址是:

http://demo.dcloud.net.cn/payment/wxpayv3.HBuilder/?total=1  返回数据如下是个json_encode的数组

{"appid":"wx0411fa6a39d61297","noncestr":"5v5efv7JKmDGv91X","package":"Sign=WXPay","partnerid":"1230636401","prepayid":"wx28170035285029c12927cdc40885888318","timestamp":1545987635,"sign":"56A6442588EB590F57EF48F2EC104DE9"}

微信支付 测试一定要打包,并且签名才能调起来的!!!!!!!!!!!

前端代码

	var channel=null;aliChannel=null;wxChannel =null;
	// 第一步. 获取支付通道
	function plusReady(){
		plus.payment.getChannels(function(channels){
				channel=channels[0];
			},function(e){
				alert("获取支付通道失败："+e.message);
			});
		plus.payment.getChannels(function(channels){
			for(var i=0;i从服务器请求支付订单
	function pay(payway){
		var id = $('#id').val();
		var PAYSERVER=''; 
			if(payway =='alipay'){
				PAYSERVER=ALIPAYSERVER+id;
				channel = aliChannel;
			}else if(payway =='wxpay'){
				PAYSERVER=WXPAYSERVER+id;
				channel = wxChannel;
			}else{
				plus.nativeUI.alert("不支持此支付通道！",null,"XXX");
				return;
			}
			$.ajax({
			  url:PAYSERVER,
			  type:'get',
			  dataType:'json',
			  data:'',
			}).done(function(msg){
				if(msg.status == 1){
					plus.payment.request(channel,msg.content,function(result){
						plus.nativeUI.alert("支付成功！",function(){
							location.href = 'user.html';
						});
					},function(error){
						plus.nativeUI.alert("支付失败");
					});
				}else{
					plus.nativeUI.alert(msg.content);
				}
			});
	}
