這篇文章將為大家詳細(xì)講解有關(guān).net如何實(shí)現(xiàn)微信公眾賬號(hào)接口開發(fā),小編覺得挺實(shí)用的,因此分享給大家做個(gè)參考,希望大家閱讀完這篇文章后可以有所收獲。
網(wǎng)站建設(shè)、基于HTML5建站技術(shù)的Web開發(fā)、手機(jī)站開發(fā)、微信開發(fā)等互聯(lián)網(wǎng)應(yīng)用服務(wù)。成都創(chuàng)新互聯(lián)公司始終關(guān)注著互聯(lián)網(wǎng)行業(yè)的前沿動(dòng)態(tài),創(chuàng)新互聯(lián)堅(jiān)信:真誠的態(tài)度,勤奮的工作是我們贏得客戶信賴的基礎(chǔ);而不斷創(chuàng)新、力求完美,才是創(chuàng)新互聯(lián)共同邁向美好未來的保證。說起微信公眾帳號(hào),大家都不會(huì)陌生,使用這個(gè)平臺(tái)能給網(wǎng)站或系統(tǒng)增加一個(gè)新亮點(diǎn),直接進(jìn)入正題吧,在使用之前一定要仔細(xì)閱讀官方API文檔。
API文檔地址:http://mp.weixin.qq.com/wiki/index.php
使用.net實(shí)現(xiàn)的方法:
//微信接口地址 頁面代碼:
代碼如下:
weixin _wx = new weixin();
string postStr = "";
if (Request.HttpMethod.ToLower() == "post")
{
Stream s = System.Web.HttpContext.Current.Request.InputStream;
byte[] b = new byte[s.Length];
s.Read(b, 0, (int)s.Length);
postStr = Encoding.UTF8.GetString(b);
if (!string.IsNullOrEmpty(postStr)) //請(qǐng)求處理
{
_wx.Handle(postStr);
}
}
else
{
_wx.Auth();
}
具體處理類
代碼如下:
///
/// 微信公眾平臺(tái)操作類
///
public class weixin
{
private string Token = "my_weixin_token"; //換成自己的token
public void Auth()
{
string echoStr = System.Web.HttpContext.Current.Request.QueryString["echoStr"];
if (CheckSignature()) //校驗(yàn)簽名是否正確
{
if (!string.IsNullOrEmpty(echoStr))
{
System.Web.HttpContext.Current.Response.Write(echoStr); //返回原值表示校驗(yàn)成功
System.Web.HttpContext.Current.Response.End();
}
}
}
public void Handle(string postStr)
{
//封裝請(qǐng)求類
XmlDocument doc = new XmlDocument();
doc.LoadXml(postStr);
XmlElement rootElement = doc.DocumentElement;
