pengenalan
Dalam artikel ini, kami akan mencipta contoh mudah untuk menghantar mesej melalui API WhatsApp menggunakan c#.
Pada mulanya, anda mesti memastikan bahawa perpustakaan RestSharp terakhir Ver: 108.0.1 sudah sedia dan kerana kami akan menggunakan perpustakaan ini dalam artikel ini untuk menghantar mesej ke Gerbang Ultramsg.
Contoh pantas untuk API WhatsApp menggunakan C#
using System;
using RestSharp;
using System.Threading.Tasks;
namespace test
{
class Program
{
static async Task Main(string[] args)
{
string instanceId = "instance950"; // your instanceId
string token = "yourtoken"; //instance Token
string mobile = "14155552671";
string message = "WhatsApp API on UltraMsg.com works good";
var url = "https://api.ultramsg.com/" + instanceId + "/messages/chat";
var client = new RestClient(url);
var request = new RestRequest(url, Method.Post);
request.AddHeader("content-type", "application/x-www-form-urlencoded");
request.AddParameter("token", token);
request.AddParameter("to", mobile);
request.AddParameter("body", message);
RestResponse response = await client.ExecuteAsync(request);
var output = response.Content;
Console.WriteLine(output);
}
}
}Apabila kod sebelumnya dilaksanakan, dan jika mesej berjaya dihantar, respons akan menjadi seperti ini:
{"sent":"true","message":"ok","id":497}Hantar Imej

string mobile = "14155552671";
byte[] AsBytes = File.ReadAllBytes("test.jpeg");
String AsBase64String = Convert.ToBase64String(AsBytes);
var url = "https://api.ultramsg.com/" + instanceId + "/messages/image";
var client = new RestClient(url);
var request = new RestRequest(url, Method.Post);
request.AddHeader("content-type", "application/x-www-form-urlencoded");

}API WhatsApp menggunakan C# dengan WebClient
ia Tidak disyorkan untuk kerja baharu tetapi ia amat mudah, jika anda perlu melakukan permintaan http secara serentak,WebClient masih boleh digunakan.
using System;
using System.Collections.Specialized;
using System.Net;
using System.Text;
public class Program
{
public static void Main()
{
using (var wb = new WebClient())
{
var data = new NameValueCollection();
data["token"] = "95041eyo9eqixrsi";
data["body"] = "WhatsApp API on UltraMsg.com works good";
data["to"] = "14155552671";
var response =
wb
.UploadValues("https://api.ultramsg.com/instance950/messages/chat",
"POST",
data);
string responseInString = Encoding.UTF8.GetString(response);
Console.WriteLine (responseInString);
}
