Implementation of code _JAVASCRIPT techniques for micro-credit development message push

Recently do the development of micro-letter public number, there is a demand is such a message push, in the form of text to send the edited message to the micro-letter enterprise number of an application group, here to take notes, the following is the collation of content:

Define data Model public
 
class Access_token
{public
Access_token ()
{////
TODO: Add constructor logic here
//
}
string _access_token;
string _expires_in;
 
 
///Get the voucher
///public
 
string Access_token
{getting
{return _access_token;}
set {_access_token = value;}
}
 
 
///Voucher Valid time, in units: seconds
///public
 
string expires_in
{get {return
_expires_in;}
 
 
set {_expires_in = value;}
}
 
}

 Public ActionResult Index (string returnurl)
{
 
getaccess_token ();
 
Isexistaccess_token ();
 
View ();
}
 
 
 
public static Access_token Getaccess_token ()
{
string appurl = ' Https://qyapi.weixin.qq.com/cgi-bin/gettoken ?";
String AppID = "Corpid of application Group";//In Settings-rights Management-system Management Group
string appsecret = "Secret of application Group";/In Settings-"Rights Management-" System Management Group
WebClient WebClient = new WebClient ();
byte[] bytes = Webclient.downloaddata (string. Format ("{0}corpid={1}&corpsecret={2}", AppUrl, AppID, Appsecret));
string result = Encoding.GetEncoding ("Utf-8"). GetString (bytes);
Jobject jobj = jobject.parse (result);
 
String token = jobj["Access_token"]. ToString ();
String expires_in = jobj["expires_in"]. ToString ();
 
Access_token mode = new Access_token ();
Mode.access_token = token;
mode.expires_in = expires_in;
return mode
}
 
///
 

According to the current date to determine whether Access_token extended if the extended return to the new Access_token otherwise return before the Access_token

public static string Isexistaccess_token () {string Token = string.
Empty;
DateTime Youxrq; String strpath = ".. /..

Read the data in the XML file and display it//string filepath = System.Web.Hosting.HostingEnvironment.MapPath (strpath);
