最近因为项目的需要做了一个通过JSON来访问SI的例子和大家一起分享一下；
这里面的关键就是在于调用接口时首先要进行登录，并在登录后持有这次访问的CookieContainer，在下次访问后用同样一个CookieContainer去访问。
分享的例子如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Web;
using Newtonsoft.Json.Converters;
using test.ServiceReference1;
using Newtonsoft.Json;
using System.Net;
using System.IO;
using System.Web.UI.WebControls;
namespace test
{
///
/// HTTP访问代理
///
///
///
public delegate void HttpClientDelegate(DateTime sender, string content);
///
/// 封装HTTP的访问
///
public class HttpClient
{
///
/// SI方法URL
///
public string Url { get; set; }
///
/// SI内容（方法里面的参数）
///
public string Content { get; set; }
///
/// Cookie，保证登录后，所有访问持有一个Cookie；
///
static CookieContainer _cc = new CookieContainer();
///
/// HTTP访问
///
///
///
///
///
public void SysncRequest(DateTime sendTime, HttpClientDelegate resultCallback, string contentType = "")
{
byte[] postData = UnicodeEncoding.UTF8.GetBytes(Content);
HttpWebRequest httpWebRequest = WebRequest.Create(Url) as HttpWebRequest;
httpWebRequest.Method = "POST";
httpWebRequest.Accept = "application/json";
httpWebRequest.ContentLength = postData.Length;
httpWebRequest.CookieContainer = _cc;
if (contentType != "")
{
httpWebRequest.ContentType = contentType;
}
using (Stream requestStream = httpWebRequest.GetRequestStream())
{
requestStream.Write(postData, 0, postData.Length);
requestStream.Close();
}
HttpWebResponse httpWebResponse = null;
Stream responseStream = null;
StreamReader streamReader = null;
try
{
httpWebRequest.Timeout = 60 * 60 * 1000;
httpWebResponse = httpWebRequest.GetResponse() as HttpWebResponse;
responseStream = httpWebResponse.GetResponseStream();
streamReader = new StreamReader(responseStream);
string result = streamReader.ReadToEnd();
resultCallback(sendTime, result);
}
catch (Exception ex)
{
}
finally
{
if (streamReader != null) streamReader.Close();
if (responseStream != null) responseStream.Close();
if (httpWebResponse != null) httpWebResponse.Close();
}
}
}
