Asp.net core webapi调用blazorserver时出现400错误

我正在尝试设置blazor服务器应用程序，调用webapi。 当我调用API时，我一直得到一个400错误的返回

我有3个项目，projectserver和projectapi。projectserver是Blazor应用程序所在的位置，ProjectAPI是API所在的位置

我不知道apicall是否能找到API，因为它在API部分没有遇到任何断点，我完全困惑了，如果它找不到API，那么它应该返回404或其他错误，而不是400

谢谢你的努力。 这是我的密码

Projectserver，这是我将注册模型发布到API的地方

    public string message { get; set; }
    public RegisterModel r = new RegisterModel();

    private async Task Create(MouseEventArgs e)
    {
        var json = Newtonsoft.Json.JsonConvert.SerializeObject(r);
        var client = clientfactory.CreateClient("ServerApi");
        var result = await client.PostAsJsonAsync("/Account/Register",json); // check the Startup file and check base address for the Full route. 

        message = result.StatusCode.ToString();
    }
} 

ClientFactory返回startup.cs中定义的基址

services.AddHttpClient（“ServerApi”，客户端=>client.BaseAddress=新Uri（“https://localhost:44302/"));

API是Projectserver，定义如下

[Route("[controller]")]
    [ApiController]
    public class AccountContoller : ControllerBase
    {
        private readonly ApplicationDbContext _context;
        private readonly SecurityOptions _securityOptions;

        private readonly JwtIssuerOptions _jwtOptions;
        // GET: api/<Account>
        [HttpGet]
        public IEnumerable<string> Get()
        {
            return new string[] { "value1", "value2" };
        }

        // GET api/<Account>/5
        [HttpGet("{id}")]
        public string Get(int id)
        {
            return "value";
        }

        // POST api/<Account>
        [HttpPost]
        public void Post([FromBody] string value)
        {
        }
        // POST api/<Account>
        [HttpPost("Register")]
        public async Task<ActionResult<RegisterResult>> Register(RegisterModel model)
        {
            RegisterResult r = new RegisterResult();

            var Exisits = await _context.Users.Where(r => r.EmailAddress == model.Email).FirstOrDefaultAsync();

            if(Exisits != null)
            {
                r.Sucsess = false;
                r.ErrorMessage = "Email - Already Exisits";
                return r;
            }
            else
            {
                try
                {
                    User newuser = new User();
                    newuser.CreatedDateTime = DateTime.UtcNow;
                    newuser.UserID = Guid.NewGuid();
                    newuser.MobileNumber = model.MobileNumber;
                    newuser.Password = model.Password;
                    newuser.FirstName = model.FirstName;
                    newuser.Surname = model.LastName;
                    _context.Users.Add(newuser);
                    await _context.SaveChangesAsync();

                    r.Sucsess = true;
                    return r;


                }
                catch(Exception e)
                {
                    r.Sucsess = false;
                    r.ErrorMessage = e.ToString();
                    return r; 
                }
                
                

            }

            
        }

请按以下方式修改您的代码并试一试：-

var serializedBody = JsonConvert.SerializeObject(r);
var jsonRequestBodyContent = new StringContent(serializedBody, Encoding.UTF8,"application/json");
 var client = clientfactory.CreateClient("ServerApi");
 var result = await client.PostAsync("/Account/Register",jsonRequestBodyContent);

您可以在调试控制台中发布您的检查。我怀疑你发了两条斜线。try:var result=await client.PostAsJsonAsync（“帐户/注册”，json）；
var serializedBody = JsonConvert.SerializeObject(r);
var jsonRequestBodyContent = new StringContent(serializedBody, Encoding.UTF8,"application/json");
 var client = clientfactory.CreateClient("ServerApi");
 var result = await client.PostAsync("/Account/Register",jsonRequestBodyContent);
