.net Core System.Net.Http.HttpClient 發送post請求

 

string url = "http://www.xxx.com/api/postmsg";

string jsonContent = JsonConvert.SerializeObject(message);

using (var client = new HttpClient())
{
var content = new StringContent(jsonContent, Encoding.UTF8, "application/json");
//上面代碼使http Content-Type 為 application/json; charset=utf-8。如果希望Content-Type為application/json，可以使用下面兩行代碼
//content.Headers.Remove("Content-Type"); // "{application/json; charset=utf-8}"
//content.Headers.Add("Content-Type", "application/json");

client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer");
string result = client.PostAsync(url, content).Result.Content.ReadAsStringAsync().Result;
