C# WebAPI 傳入JSON, 回傳資料格式為文字 [POST]

API Code

public IHttpActionResult Post([FromBody] Api_TESTPData parameters)
{
    string result = "";
    try
    {
        if (parameters == null)
        {
            throw new Exception("參數不可為空");
        }
        /*  資料處理邏輯  */
        result = $"OK,result is {parameters.Param1}-{parameters.Param2}";
    }
    catch (Exception exp)
    {
        result = $"NG,{exp.Message}";
    }
    return Ok(result); ;
}

Paramter Code

public class Api_TESTPData
{
    public string Param1 { get; set; }
    public string Param2 { get; set; }
}

回傳結果如下,

失敗:

"NG,參數不可為空"

成功:

"OK,result is value1-value2"
