api - 颤动的http post请求显示状态码500，尽管它在邮递员中工作

Question

**flutter** 

正如您在下面的 post 方法代码中看到的，我通过 post API 为 post 传递静态数据，这些数据在 postman 中有效，但在此方法中无效

    Future addbuss() async {
    var urlpost = "https://jcien.com/api/addBusinessReceived";
    var responce = await http.post(urlpost,
    
    headers: {
      'Content-Type': 'application/json; charset=UTF-8',
      
    },
        body: jsonEncode({
          "user": "7",
          "ch_id": "1",
          "user_from": "9",
          "entry_date": "2021-05-31",
          "amount": "1234",
          "business_type": "new",
          "referral_type": "inside",
          "remarks": "demoapii",
        }));
    print(responce.statusCode);
**statusCode**
status code showing error of 500   
  }
