WebApi Post 後臺無法獲取參數

參考網址：https://www.cnblogs.com/TiestoRay/p/5032202.html

基本情況和文中描述的一樣，同時方案一也可以用，方案二沒有具體的操作，沒有測試，方案三中ajax方法會報錯，存在跨域問題

最後我的解決方法是：

var submitObject = { AffairInfo: { CurrAffairCode: "WX1576727845288" }, MaterialTakeInfoList: [], ReceiveInfoList: [] };
        $.ajax({
            url: "http://localhost:4631/Affairs/affairAccept",
            dataType: "json",
            type: "post",
            contentType: "application/x-www-form-urlencoded;charset=UTF-8",
            data: submitObject,
            success: function (rst) {
                console.log(rst);
            }
        })

小程序

var submitObject = { AffairInfo: { CurrAffairCode: "WX1576727845288" }, MaterialTakeInfoList: [], ReceiveInfoList: [] };
    wx.request({ //請求數據  
      url: api.affairAccept,
      data:submitObject,
      method: 'POST',
      success: (res) => { //請求成功返回數據 
        let result = res.data.Data;
        console.log(result);
      },
      fail: function (res) { //請求失敗
      }
    })
