public class WebServiceDemo : System.Web.Services.WebService { [WebMethod] public string HelloWorld() { return "Hello World"; } [WebMethod] public string Sum(string param1, string param2) { int num1 = Convert.ToInt32(param1); int num2 = Convert.ToInt32(param2); int sum = num1 + num2; return sum.ToString(); } }
客户端调用代码:
class Program { static void Main(string[] args) { Program program = new Program(); string url = "http://localhost:12544/WebServiceDemo.asmx"; string method = "Sum"; string num1 = "1"; string num2 = "2"; string result = program.HttpPostWebService(url, method, num1, num2); Console.WriteLine(result); Console.ReadKey(); } public string HttpPostWebService(string url,string method,string num1,string num2) { string result = string.Empty; string param = string.Empty; byte[] bytes = null; Stream writer = null; HttpWebRequest request = null; HttpWebResponse response = null; param = HttpUtility.UrlEncode("x") + "=" + HttpUtility.UrlEncode(num1) + "&" + HttpUtility.UrlEncode("y") + "=" + HttpUtility.UrlEncode(num2); bytes = Encoding.UTF8.GetBytes(param); request = (HttpWebRequest)WebRequest.Create(url + "/" + method); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = bytes.Length; try { writer = request.GetRequestStream(); //获取用于写入请求数据的Stream对象 } catch (Exception ex) { return ""; } writer.Write(bytes, 0, bytes.Length); //把参数数据写入请求数据流 writer.Close(); try { response = (HttpWebResponse)request.GetResponse(); //获得响应 } catch (WebException ex) { return ""; } #region 这种方式读取到的是一个返回的结果字符串 Stream stream = response.GetResponseStream(); //获取响应流 XmlTextReader Reader = new XmlTextReader(stream); Reader.MoveToContent(); result = Reader.ReadInnerXml(); #endregion #region 这种方式读取到的是一个Xml格式的字符串 //StreamReader reader = new StreamReader(response.GetResponseStream(), Encoding.UTF8); //result = reader.ReadToEnd(); #endregion response.Dispose(); response.Close(); //reader.Close(); //reader.Dispose(); Reader.Dispose(); Reader.Close(); stream.Dispose(); stream.Close(); return result; } }
用 PostMan 工具测试:
注意:webservice 中的方法参数变量的名字和你提供的变量名字一样;param = HttpUtility.UrlEncode
(“x”) + “=” + HttpUtility.UrlEncode (num1) + “&” +
HttpUtility.UrlEncode (“y”) + “=” + HttpUtility.UrlEncode (num2);
GRPC是一个高性能、通用的开源RPC框架,基于底层HTTP/2协议标准和协议层Protobuf序列化协议开发,支持众多的开发语言。
gRPC 也是基于以下理念:定义一个服务,指定其能够被远程调用的方法(包含参数和返回类型)。在服务端实现这个接口,并运行一个 gRPC服务器来处理客户端调用。在客户端拥有一个存根能够像服务端一样的方法。
gRPC使用protocol buffers作为接口描述语言(IDL)以及底层的信息交换格式
