微信小程序通过 C#的接口传值，没有反应，也不报错

Question

我的想法是通过js直接调用C#的接口，然后传值，把接口当一个中转站，把值传过去。

我现在修改了写法，这样提示错误了，是什么原因呢？

 wx.request({
        url: 'http://localhost:200/WebService.asmx?op=InpUser',
        method: 'POST',
        header: {
          'content-type': 'application/x-www-form-urlencoded'
        },
        data: {
          Name: this.data.MyName,
          Phone: this.data.MyPhone,
          LFY: this.data.MyLFY,
          Email: this.data.MyEmail
        },
        success: function (res) {
          if (res.data.err == 0) {
            wx.showToast({
              title: '保存成功',
              success: res => {
                setTimeout(function () {
                  wx.switchTab({
                    url: '/pages/TextInput/TextInput',
                  })
                }, 2000);
              }
            })
          } else {
            that.setData({
              msg: res.data.errtxt
            })
          }
        }

错误提示

你的webservice是基于soap的，而你提交的数据是json，这就好比一个美国人用英文和一个中国人说话，当然没用。
