我试图使用HttpClient对Web API进行POST.当我在Web API的Save方法中放置一个断点时,[FromBody] Product为null.这意味着我将产品发布到Web API的方式有问题.有人可以看看下面的代码,看看我可能会出错.我假设它与头文件和内容类型有关.
从客户端存储库到Web API的POST调用,该API应该通过JSON传递产品对象：
public async Task<Product> SaveProduct(Product product)
{
using (var client = new HttpClient())
{
client.BaseAddress = new Uri("http://localhost:99999/");
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
StringContent content = new StringContent(JsonConvert.SerializeObject(product));
// HTTP POST
HttpResponseMessage response = await client.PostAsync("api/products/save",content);
if (response.IsSuccessStatusCode)
{
string data = await response.Content.ReadAsStringAsync();
product = JsonConvert.DeserializeObject<Product>(data);
}
}
return product;
}
Web API控制器方法：
[HttpPost]
[Route("save")]
public IActionResult Save([FromBody]Product product)
{
if (customer == null)
{
return HttpBadRequest();
}
_manager.SaveCustomer(product);
return CreatedAtRoute("Get",new { controller = "Product",id = product.Id },product);
}
[FromBody]产品参数最终为null.
