C# POST 连接和断开 3g 调制解调器

Question

大家好，我很难连接和断开调制解调器 3g，我通过 Fiddler 找到了 POST 请求的外观，但无法通过按钮下的 C# 使其工作。有人有经验吗？ 我共享通过 Fiddler 嗅探的数据，希望有人知道如何修复它:(

Answer 1

好的，我找到了解决方案，也许有人会觉得它很有帮助

using (WebClient client = new WebClient())
            {
                client.Proxy = new WebProxy("192.168.100.19", 3128);


                byte[] request = client.UploadData("http://192.168.1.1/api/dialup/dial", "POST",
                Encoding.ASCII.GetBytes("<?xml version=\"1.0\" encoding=\"UTF - 8\"?><request><Action>1</Action></request>"));

                string final = Encoding.ASCII.GetString(request);
                textBox1.Text = final;

            }
