c# - 非静态方法需要 webapi 中的目标

Question

我想在 Controller 中发送 HTTP POST 请求。

这是我的代码:

[HttpPost]
public IHttpActionResult login([FromBody] ClubAPI.Models.AllRequest.login userid)
{
    using (DAL.ClubEntities db = new ClubEntities())
    {
        DAL.AspNetUser q = db.AspNetUsers.Single(t=>t.Id.Equals(userid.id.ToString()));

        if (q == null)
        {
            return Ok(new ClubAPI.Models.AllResponse.loginResponse
            {
                msg = "bad",
                state = false,
            });
        }
        return Ok(new ClubAPI.Models.AllResponse.loginResponse
        {
            msg = "good",
            state = true,
            token = q.UserName,
        });
    }
}

但现在我得到以下错误:

"Non-static method requires a target in webapi" i cant solve that. the error is related to this line: db.AspNetUsers.Single(t=>t.Id.Equals(userid.id.ToString()));

当我将 ID 更改为真实 ID，如“t.Id.Equals(2342)”时，错误得到解决；但我不想使用真实 ID。

Answer 1

Try this code instead of
DAL.AspNetUser q = db.AspNetUsers.SingleOrDefault(t=>t.Id == userid.id.ToString());
into
DAL.AspNetUser q = db.AspNetUsers.SingleOrDefault(t=>t.Id == userid.id);
