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

[csharp] view
plain copy

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

[csharp] view
plain copy

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);

[csharp] view
plain copy
