 后台数据接口：

[HttpPost]        public Response
   
    
     > LoadSchedule([FromForm]QueryScheduleOneListReq query)        {            var result = new Response
     
      
       >();            try            {                result.Result = _scheduleApp.Load(query);            }            catch (Exception ex)            {                result.Code = 500;                result.Message = ex.InnerException?.Message ?? ex.Message;            }            return result;        }
      
     
    
   

前台请求格式：

public static async Task
   
     PostAsync(string url,string data,Dictionary
    
      header=null,bool Gzip = false)        {            try            {                HttpClient client = new HttpClient(new HttpClientHandler() { UseCookies = false });                HttpContent content = new StringContent(data);                content.Headers.ContentType=new System.Net.Http.Headers.MediaTypeHeaderValue("multipart/form-data");                if (header != null)                {                    client.DefaultRequestHeaders.Clear();                    foreach (var item in header)                    {                        client.DefaultRequestHeaders.Add(item.Key, item.Value);                    }                }                HttpResponseMessage response = await client.PostAsync(url, content);                response.EnsureSuccessStatusCode();                string responseBody = "";                if (Gzip)                {                    GZipInputStream inputStream = new GZipInputStream(await response.Content.ReadAsStreamAsync());                    responseBody = new StreamReader(inputStream).ReadToEnd();                }                else                {                    responseBody = await response.Content.ReadAsStringAsync();                }                return responseBody;            }            catch (Exception ex)            {                throw;            }            return null;                    }
    
   

 第一个问题请求的时候会抛出异常，把 content.Headers.ContentType=new System.Net.Http.Headers.MediaTypeHeaderValue("multipart/form-data");这行代码去掉，异常就没有了。

第二个问题就是前台的数据提交不上去
