Question

这是我的客户代码

var client = new HttpClient();
            client.BaseAddress = new Uri(BASE_URL);
            var multipart = new MultipartFormDataContent();
            var jsonToSend = JsonConvert.SerializeObject(template, Formatting.None);
            var body = new StringContent(jsonToSend, Encoding.UTF8, "application/json");
            multipart.Add(body, "JsonDetails");
            return client.PostAsync("jsons", multipart);

服务器代码为

 [HttpPost("jsons")]
        public async Task<IActionResult> RequestJson([FromBody]Person person)
        {

        if (person != null)
        {
            return Ok("true");
        }


        return Ok("false");

人员代码

public class Person
    {
        public string Name { get; set; }
        public string Position { get; set; }
    }

当从客户端调试我的帖子时，不要敲服务器，在邮递员中，我的帖子发送并且我可以看到我的对象属性

只需直接发布StringContent而不使用Multipart-Form：

var client = new HttpClient
{
    BaseAddress = new Uri(BASE_URL)
};

var jsonToSend = JsonConvert.SerializeObject(template, Newtonsoft.Json.Formatting.None);

var body = new StringContent(jsonToSend, Encoding.UTF8, "application/json");

return client.PostAsync("jsons", body)

ASP.NET Core Web API如何从客户端C＃发送json对象
