[英]How to Call a WebService without using WebReference?
I want to know if there is someone who had use a Class to Call a WebService, this WS receives an integer after the organizational references and responds into a json file, 我想知道是否有人使用类来调用WebService,此WS在组织引用后收到一个整数并响应json文件,
Actually my issue is to call the webservice without using a webreference, and read the json file and parse it into a dictionary , 实际上我的问题是在不使用webreference的情况下调用webservice,并读取json文件并将其解析为字典,
I appreciate your help 我感谢您的帮助
Best Regards, i let you my code 最诚挚的问候,我告诉你我的代码
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Net;
using Dimex.ChangeSAP.Core.Utilities;
namespace Dimex.ChangeSAP.Core.Utilities
{
class ConsumirWebService
{
public void ConsumirWS()
{
Dimex.ChangeSAP.Core.Entities.Seguridad.Usuario users = new Dimex.ChangeSAP.Core.Entities.Seguridad.Usuario();
int idUsuaro = users.IdUsuario;
try
{
System.Net.WebRequest req = System.Net.WebRequest.Create("http://192.168.8.97/PassportPruebas/api/partners?enterprise_system_id=1&organizational_reference=" + idUsuaro);
//req.Proxy = new System.Net.WebProxy(ProxyString, true);
//Add these, as we're doing a POST
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
//We need to count how many bytes we're sending.
//Post'ed Faked Forms should be name=value&
string postData = "OPERATION_NAME=ADD_REQUEST&TECHNICIAN_KEY=90BA&INPUT_DATA=" + sendXML;
byte[] bytes = System.Text.Encoding.ASCII.GetBytes(postData);
req.ContentLength = bytes.Length;
System.IO.Stream os = req.GetRequestStream();
os.Write(bytes, 0, bytes.Length); //Push it out there
os.Close();
System.Net.WebResponse resp = req.GetResponse();
if (resp == null)
{
return null;
}
System.IO.StreamReader sr =
new System.IO.StreamReader(resp.GetResponseStream());
string respuesta = sr.ReadToEnd().Trim();
return respuesta;
}
catch (Exception ex)
{
return "";
//throw or return an appropriate response/exception
}
}
}
}
Well Actually here is my code for anyone with this kind of issue too, 那么实际上这里是我的代码也适用于任何有此类问题的人,
public static string LlamarWebService(string url)
{
try
{
System.Net.WebRequest req = System.Net.WebRequest.Create(url);
req.ContentType = "application/json";
req.Method = "GET";
System.Net.WebResponse resp = req.GetResponse();
if (resp == null) return null;
System.IO.StreamReader sr =
new System.IO.StreamReader(resp.GetResponseStream());
string respuesta = sr.ReadToEnd().Trim();
return respuesta;
}
catch (Exception ex)
{
throw ex;
// return "";
//throw or return an appropriate response/exception
}
}
您可以在visualstudiocommand提示符下使用wsdl实用程序或svcutil创建代理类,输入命令wsdl.exe / out:[文件的路径和名称] /语言:CS
