您好，我将DTO用于单个值(Id)&尝试使用ApiController发布到Db，但是在单击按钮时，我不断收到错误400，该错误将我引向xhr.send错误. (即使用asp core 2.1) 代码 : @section脚本{

Hello im using a DTO for a single value(Id) & trying to post to Db using ApiController but on button click I keep getting error 400 that is referring me to xhr.send error. (im using asp core 2.1 ) Code : @section Scripts{

<script type="text/javascript"> $(document) .ready(function() { $(".js-toggle-HandShake") .click(function(e) { var button = $(e.target); console.log(button.attr("data-QuettaOfferId")); //Value=24 >> OK $.post("/Api/HandShake/", { QuettaOfferId: button.attr("data-QuettaOfferId") }) // Error in > POST localhost:44339/Api/HandShake/ 400 () & //in jquery>> xhr.send( options.hasContent && options.data || null ); .done(function() { button .text("Chousen"); }) .fail(function() { alert("Something failed"); }); }); }); </script>

} & ApiController代码

} & the ApiController code

[Microsoft.AspNetCore.Mvc.Route("api/[controller]")] [ApiController] [Microsoft.AspNetCore.Authorization.Authorize] public class HandShakeController : ControllerBase { private readonly ApplicationDbContext _context; private readonly UserManager<IdentityUser> _userManager; // private readonly IHostingEnvironment hostingEnvironment; public HandShakeController(ApplicationDbContext context ,UserManager<IdentityUser> userManager/*, IHostingEnvironment environment*/) { _context = context; _userManager = userManager; //hostingEnvironment = environment; } [Microsoft.AspNetCore.Mvc.HttpPost] // public IHttpActionResult HandShakes(HandShakeDto dto) public IActionResult HandShakes(HandShakeDto dto) { var userId = _userManager.GetUserId(User); var check = _context.Quetta.Where(u => u.SiteUserId == userId); if ( _context.handShakes.Any(f => f.QuettaOfferId == dto.QuettaOfferId)) return BadRequest("Some error Msg"); if (check.Any()) { var hand = new HandShake { QuettaOfferId = dto.QuettaOfferId }; try { _context.handShakes.Add(hand); _context.SaveChangesAsync(); return Ok(); } catch (Exception e) { Console.WriteLine(e); return BadRequest("Some error Msg"); } } else{ return BadRequest("");} // Check if the user id that publish the ed = login user. //if so add the offer to selected table, } }

im使用asp core 2.1&强烈怀疑问题出在ApiController中，但我不确定.

im using asp core 2.1 & strongly suspect that the problem is in the ApiController but im not sure.

DTO

public class HandShakeDto { public int QuettaOfferId { get; set; } }

推荐答案

尝试替换 $.post("/Api/Hand/", { QuettaOfferId: button.attr("data-QuettaOfferId") }) 经过 $.post("/Api/HandShake/", { QuettaOfferId: button.attr("data-QuettaOfferId") })

Try replacing $.post("/Api/Hand/", { QuettaOfferId: button.attr("data-QuettaOfferId") }) By $.post("/Api/HandShake/", { QuettaOfferId: button.attr("data-QuettaOfferId") })

因为您的api控制器名称是HandShakeController

as your api controller name is HandShakeController
