小程序微信支付

小程序前端JS代码

import {
  zf
} from '../../api/bx.js';
//通过zf  API(创建zf   API阅读绑定执行event(‘方法’，【参数】)); 获取timeStamp,nonceStr,package,signType,paySign
zf(value).then(res => {
      console.log("数据");
      var jsConfig = res.data.result;
      wx.requestPayment({
        timeStamp: jsConfig.timestamp,
        nonceStr: jsConfig.nonceStr,
        package: jsConfig.package,
        signType: jsConfig.signType,
        paySign: jsConfig.paySign,
        success: function (res) {
          console.log('成功失败');
          console.log(res);
          

        },
        fail: function (e) {
          console.log('成功失败');
          console.log(e);
          wx.hideLoading();
          return app.Tips({ title: '取消支付' }, { tab: 5, url: goPages + '&status=2' });
        },
        complete: function (e) {
          console.log('失败');
          console.log(e);
          wx.hideLoading();
          //关闭当前页面跳转至订单状态
          if (res.errMsg == 'requestPayment:cancel') return app.Tips({ title: '取消支付' }, { tab: 5, url: goPages + '&status=2' });
        },
      })
    }).catch(msg => {
      console.log("失败");
      console.log(msg);
    });

后台创建好的API
