  1. 直接把里面的参数替换成你的就可以了，前提是你要开通的有微信支付功能，需要商户号，appid，appsecret,openid，
  3. openid的获取比较简单，我再写一篇博客做介绍，不懂得可以私聊我
  5. //小程序端代码：
  7. pay:function(){
  8. var that=this
  9. wx.getStorage({
  10. key: 'openid',
  11. success: function(res) {
  12. wx.request({
  13. //这里是后台的处理方法，url是自定义的，直接换成你自己的后台处理方法即可，Wx_Pay这个方法在下面写的有
  14. //后台用的php做处理，java的可以参考方法，道理都是一样的
  15. url: url + 'Wx_Pay',
  16. data: {
  17. //用户的openid
  18. openid:res.data,
  19. fee: that.data.totalPrice, //支付金额
  20. details: that.data.goodsList[0].goods_name,//支付商品的名称
  21. },
  22. success:function(result){
  23. if(result.data){
  24. //out_trade_no=res.data['out_trade_no'];
  25. wx.requestPayment({
  26. timeStamp: result.data['timeStamp'],
  27. nonceStr: result.data['nonceStr'],
  28. package: result.data['package'],
  29. signType: 'MD5',
  30. paySign: result.data['paySign'],
  31. 'success':function(successret){
  32. console.log('支付成功');
  33. //获取支付用户的信息
  34. wx.getStorage({
  35. key: 'userInfo',
  36. success: function (getuser) {
  37. //加入订单表做记录
  38. wx.request({
  39. url: url + 'Wx_AddOrder',
  40. data: {
  41. uname: getuser.data.nickName,
  42. goods: that.data.goodsList[0].goods_name,
  43. price: that.data.totalPrice,
  44. openid:res.data,
  45. },
  46. success: function (lastreturn) {
  47. console.log("存取成功");
  48. }
  49. })
  50. },
  51. })
  52. },'fail':function(res){
