在 C# 中使用 whatsappAPI 将消息发送到另一个号码

Question

我想在 C# 中使用 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 年为 .NET 安装了 WhatsAppi。

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();

当我运行输出以下代码时。

    connected to whatsapp

   at WhatsAppApi.WhatsEventBase.fireOnConnectSuccess()
   at WhatsAppApi.WhatsAppBase.Connect()

有人可以告诉我如何解决这个问题吗？

Answer 1

Invalid length for a Base-64 char array or string.

表示您应该在某处使用了 base-64 编码的字符串。从https://github.com/andregsilv/WhatsAppApi/blob/master/WhatsTest/Program.cs (line 29), the password seems to be base64-encoded. Be sure to follow the same pattern as e.g. in C# How to send messages with whatsapi.net?

Answer 2

the.net 版本派生的 php 版本由于法律原因已停止。没有真正的 whatsapp api 如果你 google 它

Answer 3

您需要对密码进行Base64编码。

public static string Base64Encode(string text)
{
    return System.Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes(text));
}

然后打电话给

WhatsApp wa = new WhatsApp(from, Base64Encode("357168069647463"), "abc", false, false);
