Once the order is assumed that data is sent to the background, here is the return of the payment interface

    {
        "return_code": "SUCCESS",
        "return_msg": "OK",
        "appid": "wxd678efh567hg6787",
        "mch_id": "12345678",
        "nonceStr": "5K8264ILTKCH16CQ2502SI8ZNMTM67VS",
        "paySign": "22D9B4E54AB1950F51E0649E8810ACD6",
        "result_code": "SUCCESS",
        "packageValue": "prepay_id=wx2017033010242291fcfe0db70013231072", 
　　　　　"timeStamp": "1490840662" 
} 

After obtaining the relevant data to initiate micro-channel pay

                wx.requestPayment ({ 
                  timeStamp: payParam.timeStamp.toString (),      // 1490840662, timestamp 
                  nonceStr: payParam.nonceStr,     // 5K8264ILTKCH16CQ2502SI8ZNMTM67VS, not longer than a 32-bit random string 
                  Package: payParam.packageValue,    
                   // Package Format: prepay_id = wx2017033010242291fcfe0db70013231072, orders returned interface prepay_id, pre-paid transaction session identifier 
                  signType: 'MD5',   // signature algorithm type, default MD5, HMAC-SHA256 support and MD5 
                  paySign: payParam.paySign, // signature, assumes that stitching detail signature format below 
                  success: function (RES) { 
                    console.log ( "payment process success" );
                  }, 
                  Fail: function (RES) { 
                    the console.log ( "payment process failed" ); 
                  }, 
                  Complete: function (RES) { 
                    the console.log ( "payment process ends" ); 
                  }

paySign格式：paySign = MD5(appId=wxd678efh567hg6787&nonceStr=5K8264ILTKCH16CQ2502SI8ZNMTM67VS&package=prepay_id=wx2017033010242291fcfe0db70013231072&signType=MD5&timeStamp=1490840662&key=qazwsxedcrfvtgbyhnujmikolp111111) = 22D9B4E54AB1950F51E0649E8810ACD6
