Question

我想从我的代码发布数据，但没有更改数据。当我调试代码时它得到了200，这意味着代码是好的。我尝试在fiddler中测试并且数据已成功更改。我想知道哪里错了？这是我的服务，包括网址

 public static async Task<string> PostOrderAsync(MachinePostModel Order)
        {
            try
            {
                var client = new HttpClient();
                string data = JsonConvert.SerializeObject(Order);
                var content = new StringContent(data, Encoding.UTF8, "application/json");
                var response = await client.PostAsync("http://94.205.253.150:2016/api/JobOrder", content);

                return data;
            }
            catch
            {
                return null;
            }
        }

这是我发送订单对象的步骤

 private async Task<bool> AcceptPostOrder()
        {
            MachinePostModel OrderDetails = new MachinePostModel();
                try
                {

                OrderDetails.ID = 1163;
                OrderDetails.joStatus = "should to wait";
                OrderDetails.remarks = "hello remarks";

                var Client = await Services.MachineTestPostService.PostOrderAsync(OrderDetails);
                    return true;

                }
                catch (Exception exc)
                {
                await MachineTestOrderView.machineobj.DisplayAlert("Alert", exc.Message, "OK");
                return false;
            }

        }

最后我的模特

   public class MachinePostModel
    {
        public int ID { get; set; }
        public string remarks { get; set; }
        public string joStatus { get; set; } 

    }

获取链接以检查数据是否已更改

http://94.205.253.150:2016/api/JobOrder/Get?regId=1&driverID=35&status=All%20Status

您的代码中存在一些错误。首先，使用HttpPost属性修饰您的操作，并为发送的复杂对象添加参数。

[HttpPost]
private async Task<bool> AcceptPostOrder(MachinePostModel Order)
{
    MachinePostModel OrderDetails = new MachinePostModel();
    try
    {
        OrderDetails.ID = 1163;
        OrderDetails.joStatus = "should to wait";
        OrderDetails.remarks = "hello remarks";

        var Client = await Services.MachineTestPostService.PostOrderAsync(OrderDetails);
            return true;
    }
    catch (Exception exc)
    {
        await MachineTestOrderView.machineobj.DisplayAlert("Alert", exc.Message, "OK");
        return false;
    }
}

并且，没有路由定义为api/JobOrder，因此我假设您尝试发布数据AcceptPostOrder方法。更改请求端点;

var response = await client.PostAsync("http://94.205.253.150:2016/api/AcceptPostOrder", content);

Post方法HTTP响应为200但没有数据更改在web api中
