c#调用微信接口获取token值

废话不说，一个方法实现，这里的url 参数即为配置好的访问路径，

string url = "https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" + AppID + "&secret=" + AppSecret;  

这里的两个参数AppID、AppSecret对应微信公众账号

public static string GetPage(string url )
{
Stream instream = null;
StreamReader sr = null;
HttpWebResponse response = null;
HttpWebRequest request = null;
Encoding encoding = Encoding.UTF8;

// 准备请求...
try
{
// 设置参数
request = WebRequest.Create(posturl) as HttpWebRequest;
CookieContainer cookieContainer = new CookieContainer();
request.CookieContainer = cookieContainer;
request.AllowAutoRedirect = true;
request.Method = "POST";
//发送请求并获取相应回应数据
response = request.GetResponse() as HttpWebResponse;
//直到request.GetResponse()程序才开始向目标网页发送Post请求
instream = response.GetResponseStream();
sr = new StreamReader(instream, encoding);
//返回结果网页（html）代码
string content = sr.ReadToEnd();
Logs.WriteLog("" + DateTime.Now + content);　　//记录返回结果
return content;
}
catch (Exception ex)
{
string err = ex.Message;
return string.Empty;
}
}
