asp.net 核心 web api 如何从客户端 c# 发送 json 对象

asp.net core web api how to send json object from client side c#

这是我的客户端代码

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);

服务器代码是

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

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


        return Ok("false");

个人代码

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

当调试我的 post 从客户端不敲服务器时,在 postman 我的 post 发送中我可以看到我的对象 属性

直接 post StringContent 而不是 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)
