Angular Bad Request 在 post 请求中向服务器发送数据时出错

Question

我的angular代码：

var url = this.baseUrl + "api/ajax/PostProduct";
  console.log(tempProduct);
  this.http.post<Product>(url, tempProduct).subscribe(res => {
    console.log("Product " + res.id + " has been created.");
  }, error => console.log(error));

我的服务器api:

 [HttpPost]
    [Route(nameof(PostProduct))]
    public Product PostProduct([FromBody]Product product)
    {
        product.CreateDate = DateTime.Now;
        dbContext.Products.Add(product);
        dbContext.SaveChanges();
        return product;
    }

我试过邮递员，它能够发送请求。
