## uni-app微信支付失败\{“errMsg”:“requestPayment:fail errors”\} ##

// 微信支付
    // data为后端获取到的支付信息
    let postInfo = { 
    	sign: data.sign,
    	prepayid: data.prepayId,
    	partnerid: data.partnerId,
    	appid: data.appId,
    	timestamp: data.timeStamp,
    	noncestr: data.nonceStr,
    	package: data.package,
     }
    let postDataInfo = JSON.stringfy(postInfo) // 微信支付orderInfo需要json支付串格式
    let _this = this
    uni.requestPayment({ 
    	provider: 'wxpay',
    	orderInfo: postDataInfo, 
    	signType: 'HMAC-SHA256', // 签名类型必须与后端解密方式一致
    	success: function(res) { 
    			uni.navigateTo({ 
    			url: './pay-success?money?=' + _this.postData.hjjkPayOrderRo.totalMoney
    			})
    	},
    	fail: function(err) { 
    			 console.log('微信支付失败', err);
    	},
    	complete(res) { 
    			console.log('微信支付完成', res);
    	}
    });
    // 支付宝支付
    aliPay(data) { 
    	let _this = this
    	uni.requestPayment({ 
    		provider: 'alipay',
    		orderInfo: data, //支付宝订单数据 支付宝订单信息为一串包含支付信息的支付串
    		success: function(res) { 
    			let total = _this.postData.hjjkPayOrderRo.totalMoney
    			uni.navigateTo({ 
    				url: `/pages/hjjk/modules/service/pay/pay-success?money=${ total}`
    						})
    		 },
    		 fail: function(err) { 
    			console.log('支付宝支付失败' + JSON.stringify(err));
    		  }
    	  });
    }

`{"errMsg":"requestPayment:fail errors"}`错误的原因是如果`signType`不指定默认为MD5加密，可能与后端的加密方式不一致导致错误
