Question

如何在执行webapi操作后在json中发送成功/失败响应？我有一个名为FundTransfer的函数，如何实现它像输出：如下所示

   FundTransfer(string FromAccountNo, string ToAccountNo, decimal Amount, 
   string Remarks)

   Output:
   return: Success OR Fail with reason
   string MsgCode: 00 (means success) OR 11 (means failure)
   string Message: "Insufficient Balance ... or any other reason" (if fail, 
   there must be some reason in the Message")

当我调用api时，它会执行并在成功执行时发送 true

我的Webapi行动（现在）

    [HttpPost]
    [ActionName("transfer")]
    public IHttpActionResult FundTransfer([FromBody] FundTransfer transfer)
    {
        var transferData = BusinessLayer.Api.AccountHolderApi
            .FundTransfer(transfer);

        return Ok(transferData);
    }

业务层

    public static bool FundTransfer(FundTransfer transferData)
     {
        return 
        DatabaseLayer.Api.AccountHolderApi.FundTransfer(transferData);
     }

DatabaseLayer

   public static bool FundTransfer(FundTransfer transferData)
    {

        string sql = @"SELECT * FROM sms.post_fund_transfer('" + 
        transferData.FromAccount + "','" +
                     transferData.ToAccount + "','" + transferData.Amount + 
        "','" + transferData.Statement + "')";

        using (var command = new NpgsqlCommand(sql))
        {
            return DBOperations.ExecuteNonQuery(command);
        }
    }

我仍然在学习webapi并且确实找到了一些与回复消息相关的问题/答案，但无法通过。非常感谢。

谢谢。

您可以创建一个包含响应数据类型的类

public class responseMsg
{
    public class MsgCode { get; set; }
    public class Message { get; set; }
}

然后在您的FundTransfer方法中使用它

public responseMsg FundTransfer(string FromAccountNo, string ToAccountNo, decimal Amount, string Remarks)
{
    //implement logic and create a response 

    return new responseMsg { MsgCode = "11", Message="Insufficient Balance ..." };
}

然后在api方法中读取MsgCode并设置http响应代码

[HttpPost]
[ActionName("transfer")]
public IHttpActionResult FundTransfer([FromBody] FundTransfer transfer)
{
    //call your logic which response with the responseMsg
    var response = logic();

    if(response.MsgCode == "11")
    {
        return Content(HttpStatusCode.BadRequest, response.Message);
    }
    else
    {
        return Ok(response.Message);
    }
}
