没有在 localhost 监听的端点

Question

我的控制台应用程序托管的 wcf 服务在客户端出现错误。现在这适用于我的浏览器，但不适用于我的 win 表单，它是一个简单的按钮文本框和标签：

    public ServiceReference1.Service1Client testClient = new ServiceReference1.Service1Client();

    private void button1_Click_1(object sender, EventArgs e)
    {
        label1.Text = testClient.GetData(Convert.ToString(textBox1.Text));
    }

我得到的错误是：

http://localhost:8000/hello 没有端点监听 可以接受消息。这通常是由不正确的地址引起的 或 SOAP 操作。有关详细信息，请参阅 InnerException（如果存在）。

主机控制台应用代码：

class Program
{
    static void Main(string[] args)
    {
        WebHttpBinding binding = new WebHttpBinding();
        WebServiceHost host =
        new WebServiceHost(typeof(Service1));
        host.AddServiceEndpoint(typeof(IService1),
        binding,
        "http://localhost:8000/hello");
        host.Open();
        Console.WriteLine("Hello world service");
        Console.WriteLine("Press <RETURN> to end service");
        Console.ReadLine();
    }
}

为了访问 RESTful 服务，您可以使用以下代码：

private string UseHttpWebApproach<T>(string serviceUrl, string resourceUrl, string method, T requestBody)
        {
            string responseMessage = null;
            var request = WebRequest.Create(string.Concat(serviceUrl, resourceUrl)) as HttpWebRequest;
            if (request != null)
            {
                request.ContentType = "application/xml";
                request.Method = method;
            }    

            if(method == "POST" && requestBody != null)
            {                    
                byte[] requestBodyBytes = ToByteArrayUsingJsonContractSer(requestBody);                
                request.ContentLength = requestBodyBytes.Length;
                using (Stream postStream = request.GetRequestStream())
                    postStream.Write(requestBodyBytes, 0, requestBodyBytes.Length);

            }

            if (request != null)
            {
                var response = request.GetResponse() as HttpWebResponse;
                if(response.StatusCode == HttpStatusCode.OK)
                {
                    Stream responseStream = response.GetResponseStream();
                    if (responseStream != null)
                    {
                        var reader = new StreamReader(responseStream);

                        responseMessage = reader.ReadToEnd();
                    }
                }
                else
                {
                    responseMessage = response.StatusDescription;
                }
            }
            return responseMessage;
        }

ServiceUrl : http://localhost:8000

ResourceUrl : hello/yourstring

方法：GET

请求正文：空
