這篇文章主要為大家詳細(xì)解析了微信公眾平臺(tái)開發(fā)之獲得ACCESSTOKEN .Net代碼，感興趣的小伙伴們可以參考一下
成為了開發(fā)者之后微信平臺(tái)會(huì)給您appid和secret，在訂閱號(hào)中是沒(méi)有的，所以因該申請(qǐng)一下服務(wù)號(hào)，有了ACCESSTOKEN才能做添加菜單，上傳/下載圖片等功能。
private string GetToken()
{
// 也可以這樣寫:
//return GetPage("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的secret", "");
string res = "";
HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential
&appid=你的appid&secret=你的secret");
req.Method = "GET";
using (WebResponse wr = req.GetResponse())
{
HttpWebResponse myResponse = (HttpWebResponse)req.GetResponse();
StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);
string content = reader.ReadToEnd();
List<ACCESSTOKEN> myACCESSTOKEN = Json.JSONStringToList<ACCESSTOKEN>(content);
res = myACCESSTOKEN[0].access_token;
}
return res;
}
public string GetPage(string posturl, string postData)
{
Stream outstream = null;
Stream instream = null;
StreamReader sr = null;
HttpWebResponse response = null;
HttpWebRequest request = null;
Encoding encoding = Encoding.UTF8;
byte[] data = encoding.GetBytes(postData);
// 準(zhǔn)備請(qǐng)求...
try
{
// 設(shè)置參數(shù)
request = WebRequest.Create(posturl) as HttpWebRequest;
CookieContainer cookieContainer = new CookieContainer();
request.CookieContainer = cookieContainer;
request.AllowAutoRedirect = true;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
outstream = request.GetRequestStream();
outstream.Write(data, 0, data.Length);
outstream.Close();
//發(fā)送請(qǐng)求并獲取相應(yīng)回應(yīng)數(shù)據(jù)
response = request.GetResponse() as HttpWebResponse;
//直到request.GetResponse()程序才開始向目標(biāo)網(wǎng)頁(yè)發(fā)送Post請(qǐng)求
instream = response.GetResponseStream();
sr = new StreamReader(instream, encoding);
//返回結(jié)果網(wǎng)頁(yè)（html）代碼
string content = sr.ReadToEnd();
string err = string.Empty;
return content;
}
catch (Exception ex)
{
string err = ex.Message;
Response.Write(err);
return string.Empty;
}
}
