小程序php支付，前后端分离

小程序端：

xml：

<button type="default" bindtap="payOrder">支付</button>

js：

payOrder: function (event) {

wx.request({

url: 'http://test.dailingmei.com/api/Mini/miniGetPayMoney',

data: { //发送给后台的数据

token: wx.getStorageSync('token'),

order_list_id: "88"

},

header: { //请求头

'content-type': 'application/x-www-form-urlencoded'

},

method: "POST", //get为默认方法/POST

success: function (res) {

console.log(res);

wx.requestPayment({

timeStamp: res.data.data.result.timeStamp,

nonceStr: res.data.data.result.nonceStr,

package: res.data.data.result.package,

signType: 'MD5',

paySign: res.data.data.result.paySign,

success: function (res) {

// success

console.log(res);

},

fail: function (res) {

// fail

console.log(res);

},

complete: function (res) {

// complete

console.log(res);

}

})

},

fail: function (err) { }, //请求失败

complete: function () { } //请求完成后执行的函数

})

},
