post +User-Agent +Authorization
public static string PostJson(string url,string json, string token) { using (var client = new HttpClient()) { //client.DefaultRequestHeaders.Add("Authorization", "Bearer "+token+""); //var data = new StringContent(json, Encoding.UTF8, "application/json"); //var response = client.PostAsync(url, data).GetAwaiter().GetResult(); //string result = response.Content.ReadAsStringAsync().Result; //return result; client.DefaultRequestHeaders.Add("User-Agent", "Apifox/1.0.0 (https://apifox.com)"); var request = new HttpRequestMessage(HttpMethod.Post, url) { Content = new StringContent(json, Encoding.UTF8, "application/json") }; request.Headers.Authorization = new AuthenticationHeaderValue("Bearer", token); var response = client.SendAsync(request).GetAwaiter().GetResult(); string result = response.Content.ReadAsStringAsync().Result; return result; } }
post + form-data
static async Task Main(string[] args) { using (var client = new HttpClient()) { var formData = new MultipartFormDataContent(); formData.Add(new StringContent("John Doe"), "name"); formData.Add(new StringContent("[email protected]"), "email"); var response = await client.PostAsync("http://example.com/submit-form", formData); string responseBody = await response.Content.ReadAsStringAsync(); Console.WriteLine(responseBody); } }
我们使用formData.Add
