   ...
   amount: this.price,
   /* 支付后支付宝return的url */
   // returnUrl: 'www.baidu.com'
   returnUrl: window.location.origin + window.location.pathname + '?userParams=' + this.userParams
  }
  this.$http(
   this.$apiSetting.alipay,
   data
  ).then(res => {
   this.$loading.hide()
   if (res.data.statusCode === '000000') {
    const div = document.createElement('div')
    /* 此处form就是后台返回接收到的数据 */
    div.innerHTML = res.data.data.alipayInfo
    document.body.appendChild(div)
    document.forms[0].submit()
   }
  }, error => {
