如何从 Windows 应用程序使用 Send FromBody 调用 Get 方法

Question

我有一个 API 接受 get 方法中的 [FromBody] 那么我如何调用这个 Get 方法

我的 API 是

     [BearerAuth]
     [HttpGet]
     public Dictionary<long, string> GetEmployees([FromBody] Employee obj)
    {
        Dictionary<long, string> dic = new Dictionary<long, string>();

        //Some Implemenation

        return dic;
    }

现在我正在尝试从 Windows 应用程序调用它

            using (WebClient webRequest = new WebClient())
            {
                Employee emp = new Employee { EmpId = 1, Name = "Mohan", Gender = "Male", MobileNo = "9560498289", Salary = 50000 };
                string url = APIUrl_2 + "/APITest/GetMethod_FromBody";

                //string JsonString = JsonConvert.SerializeObject(emp);
                //ASCIIEncoding encoding = new ASCIIEncoding();
                //byte[] data = encoding.GetBytes(JsonString);

                WebRequest request = WebRequest.Create(url);
                request.Method = "GET";
                request.Headers["Authorization"] = "Bearer " + "AuthKey";
                using (WebResponse response = request.GetResponse())
                {

                }
              }

请谁能帮我在 FromBody 中发送员工数据，它被调用但 Employee 为空。

我只能通过get方法来做。

提前致谢

[FromBody] 属性不能用于 [HttpGet] 修饰方法。 为了修复代码，您可以进行两种可能的修改：

1. 第一个选项：将您的方法转换为 POST 并在请求正文中发送您的员工对象：

    [BearerAuth]
    [HttpPost]
    public Dictionary<long, string> GetEmployees([FromBody] Employee obj)
    {
       Dictionary<long, string> dic = new Dictionary<long, string>();
   
       //Some Implemenation
   
       return dic;
    }
   

还有你的客户端代码：

     using (WebClient webClient = new WebClient())
     {
        //add authorization
        Employee emp = new Employee { EmpId = 1, Name = "Mohan", Gender = "Male", MobileNo = "9560498289", Salary = 50000 };
        string url = APIUrl_2 + "/APITest/GetMethod_FromBody";

        string jsonString = JsonConvert.SerializeObject(emp);

        string response = webClient.UploadString(url, jsonString);
     }

1. 第二个选项：将您的 [FromBody] 转换为 [FromUri] 并将您的员工对象作为查询字符串发送

    [BearerAuth]
    [HttpGet]
    public Dictionary<long, string> GetEmployees([FromGet] Employee obj)
    {
       Dictionary<long, string> dic = new Dictionary<long, string>();
   
       //Some Implemenation
   
       return dic;
    }
   

客户的相关部分：

webClient.QueryString.Add("EmptId", emp.EmpId);
webClient.QueryString.Add("Name", emp.Name);
webClient.QueryString.Add("Gender", emp.Gender);
...
string response = webClient.DownloadString(url);
