我想使用C#中的whatsApp API从我的号码向whatsApp上的另一个号码发送消息。为此,我在visual studio 2013中安装了WhatsAppi for .NET。
这是我正在使用的代码。
string from = "919586896325";
string to = "919856745896";
string msg = "hello";
WhatsApp wa = new WhatsApp(from, "357168069647463", "abc", false, false);
wa.OnConnectSuccess += () =>
{
System.Diagnostics.Debug.WriteLine("connected to whatsapp");
wa.OnLoginSuccess += (phoneNumber, data) =>
{
wa.SendMessage(to, msg);
System.Diagnostics.Debug.WriteLine("Message Sent");
};
wa.OnLoginFailed += (data) =>
{
System.Diagnostics.Debug.WriteLine(data);
};
wa.Login();
};
wa.OnConnectFailed += (ex) =>
{
System.Diagnostics.Debug.WriteLine("could not connect = {0}", ex);
};
wa.Connect();
当我在输出后运行此代码时。
connected to whatsapp

有人可以告诉你如何解决这个问题吗?

您需要将密码编码为Base64。
public static string Base64Encode(string text)
{
return System.Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(text));
}
然后致电
WhatsApp wa = new WhatsApp(from, Base64Encode("357168069647463"), "abc", false, false);

Base-64字符数组或字符串的长度无效。
表示您应该在某处使用base-64编码的字符串。从https://github.com/andregsilv/WhatsAppApi/blob/master/WhatsTest/Program.cs(第29行)来看,密码似乎是base64编码的。请务必遵循相同的模式,例如在C# How to send messages with whatsapi.net?
