微信支付报错问题解决
支付回调各种报错，openID、APPID等等原因，打印 console.log(typeof(res.jsApiParameters));重点把string转化为Object就ok了。每次支付请求会生成订单，根据对应订单号，修改数据库订单状态才可以完成。{ "appId":"wx1b35c*********3", "nonceStr":"nam97dundxjiisasumrevju*******", "package":"prepay_id=wx***", "signType":"MD5", "timeStamp":"1**", "paySign":"7CD01*****9"} //获取充值套餐$.ajax({ type: 'post', url: api.domain + api.recharge_package, data: { "access_token": access }, success : function(res) { if (res.status == 1) { var n = res.data.length; var menu = []; if(n < 1){ return false; } for(var i = 0;i < n;i++){ menu.push(res.data[i].id); var selected; //设置默认套餐与价格 if(i == 0){ selected = ' btn-active'; $('#money').html(res.data[i].price); } else { selected = ''; } var $list = $('' + res.data[i].name + ''); $list.appendTo($('#parent')); } $('#count').val(menu); } else { $.toptip(res.msg,'cancel'); } }, error: function(XMLHttpRequest, textStatus, errorThrown) { console.log('XMLHttpRequest.status = ' + XMLHttpRequest.status); console.log('XMLHttpRequest.readyState = ' + XMLHttpRequest.readyState); console.log('textStatus = ' + textStatus); }});//点击套餐$('body').on('click', '.js-pay', function(){ var param_b = $(this).attr('title'); var menu = $('#count').val().split(','); for(var p = 0; p < menu.length;p++) { if(menu[p] == param_b) { $('span[title="' + menu[p] + '"]').addClass('btn-active'); } else { $('span[title="' + menu[p] + '"]').removeClass('btn-active'); } } $('#money').html($(this).attr('price'));});//充值付费$("#pay").click(function() { var package = $('.btn-active').attr('title'); $.ajax({ type: 'post', url: '/recharge/pay', data: { "access_token": access, "package_id": package }, success : function(res) { console.log(typeof(res)); console.log(res.jsApiParameters); console.log(typeof(res.jsApiParameters)); if (res.status == 1) { if (typeof WeixinJSBridge == "undefined"){ if( document.addEventListener ){ document.addEventListener('WeixinJSBridgeReady', jsApiCall, false); }else if (document.attachEvent){ document.attachEvent('WeixinJSBridgeReady', jsApiCall); document.attachEvent('onWeixinJSBridgeReady', jsApiCall); } }else{ jsApiCall($.parseJSON(res.jsApiParameters),res.order_no); } } else { $.toptip(res.msg,'cancel'); } }, error: function(XMLHttpRequest, textStatus, errorThrown) { console.log('XMLHttpRequest.status = ' + XMLHttpRequest.status); console.log('XMLHttpRequest.readyState = ' + XMLHttpRequest.readyState); console.log('textStatus = ' + textStatus); } });});//调用微信JS api 支付function jsApiCall(n,order_no){ console.log(n); WeixinJSBridge.invoke( 'getBrandWCPayRequest', n, function(res){ WeixinJSBridge.log(res.err_msg); //alert(res.err_code+res.err_desc+res.err_msg); if(res.err_msg == "get_brand_wcpay_request:ok" ) { paySuccess(order_no); }else if(res.err_msg == "get_brand_wcpay_request:cancel"){ $.toast("支付取消", "cancel"); }else{ $.toast("支付失败", "forbidden"); } // 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。 } );}//微信回调成功,跳转成功页面function paySuccess(n){ $.ajax({ type: 'post', url: api.domain + api, data: { "access_token": access, "order_no": n }, success : function(res) { if (res.status == 1) { location.href = '/recharge/success'; } else { $.toptip(res.msg,'cancel'); } }, error: function(XMLHttpRequest, textStatus, errorThrown) { console.log('XMLHttpRequest.status = ' + XMLHttpRequest.status); console.log('XMLHttpRequest.readyState = ' + XMLHttpRequest.readyState); console.log('textStatus = ' + textStatus); } });} 转载地址：http://vlytl.baihongyu.com/
