HttpHelper请求封装基类，支持get请求和POS请求，方便微信开发接口交互，为后面接口交互做准备。
1、HttpHelper帮助基类
-
using System;
-
using System.Collections.Generic;
-
using System.IO;
-
using System.Linq;
-
using System.Text;
-
using System.Net;
-
using System.Net.Security;
-
-
namespace Weixin.Utils
-
{
-
public class HttpHelper
-
{
-
public static string Post(string url, string paramData)
-
{
-
return Post(url, paramData, Encoding.UTF8);
-
}
-
-
public static string Post(string url, string paramData, Encoding encoding)
-
{
-
string result;
-
-
if (url.ToLower().IndexOf("https", System.StringComparison.Ordinal) > -1)
-
{
-
ServicePointManager.ServerCertificateValidationCallback =
-
new RemoteCertificateValidationCallback((sender, certificate, chain, errors) => { return true; });
-
}
-
-
try
-
{
-
var wc = new WebClient();
-
if (string.IsNullOrEmpty(wc.Headers["Content-Type"]))
-
wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded");
-
wc.Encoding = encoding;
-
-
result = wc.UploadString(url, "POST", paramData);
-
}
-
catch (Exception e)
-
{
-
throw;
-
}
-
-
return result;
-
}
-
-
public static string Get(string url)
-
{
-
return Get(url, Encoding.UTF8);
-
}
-
-
public static string Get(string url, Encoding encoding)
-
{
-
try
-
{
-
var wc = new WebClient { Encoding = encoding };
-
var readStream = wc.OpenRead(url);
-
using (var sr = new StreamReader(readStream, encoding))
-
{
-
var result = sr.ReadToEnd();
-
return result;
-
}
-
}
-
catch (Exception e)
-
{
-
throw e;
-
}
-
}
-
}
-
}
2、帮助类使用
-
var data = "{\"touser\":\"Rich\" },";
-
data += "{\"msgtype\": \"text\"},";
-
data += "{\"text\": [{\"content\": \"test\"}]}";
-
var json = HttpHelper.Post("https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=" + accessToken, data);
-
var result = JsonHelper.Deserialize(json);
