以上是微信官方后台需要设置的，
以下是我们自己的程序页面对接配置的一些设置：
字段说明：
平台名称：看图片，关注公众号时显示的欢迎关注（平台名称）
APPID：这个必须和微信官网的一致
Appsecret:这个必须和微信官网的一致
Token：这个必须和微信官网的一致
授权域名：这个必须是微信官网设置的授权回调页面地址是一样的，
功能说明：这个就是关注公众号时显示的图文消息下的那几段话，
官方网址：这个就是点击关注公众号时显示的图文消息的跳转地址
关注时的图片：这个就是点击关注公众号时显示的图文消息的图片
处理方法：把字段信息保存到本地数据库，这里呢，我设置了两个，如果你关注了微信测试号本地测试时使用另外一个，真正的项目就切换到另外一个
设置好以后，还没有启用这个配置，只需点击一下设置默认（只是将状态更改为1而已）即可，随后，在页面调用的时候，调用微信服务类
代码如下：
/// <summary>
/// 获取微信公众号的AppId
/// </summary>
public static string GetAppId()
{
//获取使用中的微信配置信息
WeChatConfigService wcf = new WeChatConfigService();
WeChatConfigInfo wcfInfo = wcf.GetWeChatConfigInfoByInUse();
if (wcfInfo != null)
{
return wcfInfo.wechat_AppId.ToString();
}
return null; ;
} /// <summary>
/// 获取微信公众号的AppSecret
/// </summary>
public static string GetAppSecret()
{
//获取使用中的微信配置信息
WeChatConfigService wcf = new WeChatConfigService();
WeChatConfigInfo wcfInfo = wcf.GetWeChatConfigInfoByInUse();
if (wcfInfo != null)
{
return wcfInfo.wechat_AppSecret.ToString();
}
return null; ;
} /// <summary>
/// 获取本地设置的Token
/// </summary>
public static string GetToken()
{
//获取使用中的微信配置信息
WeChatConfigService wcf = new WeChatConfigService();
WeChatConfigInfo wcfInfo = wcf.GetWeChatConfigInfoByInUse();
if (wcfInfo != null)
{
return wcfInfo.wechat_Token.ToString();
}
return null; ;
} /// <summary>
/// 获取网页授权域名
/// </summary>
public static string GetpostUrl()
{
//获取使用中的微信配置信息
WeChatConfigService wcf = new WeChatConfigService();
WeChatConfigInfo wcfInfo = wcf.GetWeChatConfigInfoByInUse();
if (wcfInfo != null)
{
return wcfInfo.wechat_PostUrl.ToString();
}
return null; ;
} /// <summary>
/// 获取通行证
/// </summary>
/// <returns></returns>
public string GetAccessToken()
{
//获取使用中的微信配置信息
WeChatConfigService wcf = new WeChatConfigService();
WeChatConfigInfo wcfInfo = wcf.GetWeChatConfigInfoByInUse();
string appid = "";
string secret = "";
if (wcfInfo != null)
{
//初始化微信配置信息
appid = wcfInfo.wechat_AppId.ToString();
secret = wcfInfo.wechat_AppSecret.ToString();
} string url_token = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid="+appid+"&secret="+secret;
HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(url_token);
myRequest.Method = "GET";
HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
string content = reader.ReadToEnd();
reader.Close();
return content;
}
在项目的根目录或者特定的文件夹内，创建一个ashx文件(一般处理程序文件)，如图
public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain"; string postString = string.Empty;
if (HttpContext.Current.Request.HttpMethod.ToUpper() == "POST")
{
using (Stream stream = HttpContext.Current.Request.InputStream)
{
Byte[] postBytes = new Byte[stream.Length];
stream.Read(postBytes, , (Int32)stream.Length);
postString = Encoding.UTF8.GetString(postBytes);
} if (!string.IsNullOrEmpty(postString))
{
ResponseXML(postString);//返回给微信用户信息
} ///加载自定义菜单
