核心代码

//小程序支付相关方法
var Pay = {
	async pay(param){
		let page = getApp().globalData.currentPage
		let session = page.$session;
		if(!session.getToken() || !session.getUser().openid){
			//如果参数自带openid跳过验证
			if(!param.openid){ 
				page.showToast('请先登录')
				return;
			}
		}
		if(!param.total){
			page.showToast('请配置价格参数total')
			return;
		}
		let data = await page.$http.post(param.url||'/api/wepay/order',{
			total:param.total,
			body:param.body,
			openid:param.openid||session.getUser().openid,
		},{},'json')
		
		if(data.code!=200){
			page.showToast(data.msg)
			return;
		}
		if(this[param.paytype]){
			this[param.paytype](Object.assign(data,param))
		}else{
			page.showToast('请使用微信打开')
			return;
		}
	},
	//微信支付  
	weixin(params = {}) {
		uni.requestPayment({
		  provider: 'wxpay',
		  timeStamp: params.data.timeStamp,// 支付签名时间戳，注意微信jssdk中的所有使用timestamp字段均为小写。但最新版的支付后台生成签名使用的timeStamp字段名需大写其中的S字符
		  nonceStr: params.data.nonceStr,// 支付签名随机串，不长于 32 位  
		  package: params.data.package,// 统一支付接口返回的prepay_id参数值，提交格式如：prepay_id=\*\*\*） 
		  signType: params.data.signType,// 签名方式，默认为'SHA1'，使用新版支付需传入'MD5'  
		  paySign: params.data.paySign,// 支付签名  
		  success: res => {
			  if(typeof params.success=='function'){
				  params.success(res)
			  }else{
				  console.log('配置支付回调成功方法')
			  }
		  },
		  fail: res => {
			  if(typeof params.fail=='function'){
				  params.fail(res)
			  }else{
				  console.log('配置支付回调失败方法')
			  }
		  }
		})
	}
}
