Java Development micro-letter sharing to the circle of friends function _java

Development of micro-credit sharing function

Spent a day, the micro-letter sent to friends and to share the circle of friends to develop the function, here to share with you, to avoid detours.

two, client code.

 });

Three, the server needs the tool class and model

①ticket

Package Com.wiimedia.model;
 public class ticket{private String tid; 
 Private String ticket;
 Private String Errcode; 
 Private String errmsg;
 Private String expires_in;
 Private String Acquiretime;
 Private String noncestr;

 Private String timestamp; Public Ticket (String tid, String Ticket, String Errcode, String errmsg, String Expiresin, String acquiretime, String No
  NCESTR, String timestamp) {super ();
  This.tid = tid;
  This.ticket = ticket;
  This.errcode = Errcode;
  This.errmsg = errmsg;
  expires_in = Expiresin;
  This.acquiretime = Acquiretime;
  This.noncestr = Noncestr;
 This.timestamp = timestamp;
 Public String Gettid () {return tid;
 } public void Settid (String tid) {this.tid = tid;
 Public String GetTicket () {return ticket;
 } public void Setticket (String ticket) {this.ticket = ticket;
 Public String Geterrcode () {return errcode;
 } public void Seterrcode (String errcode) {this.errcode = Errcode; Public String geterrmsg (){return errmsg;
 } public void Seterrmsg (String errmsg) {this.errmsg = errmsg;
 Public String getexpires_in () {return expires_in;
 } public void setexpires_in (String expiresin) {expires_in = Expiresin;
 Public String Getacquiretime () {return acquiretime;
 } public void Setacquiretime (String acquiretime) {this.acquiretime = Acquiretime;
 Public String Getnoncestr () {return noncestr;
 } public void Setnoncestr (String noncestr) {this.noncestr = Noncestr;
 Public String Gettimestamp () {return timestamp;
 } public void Settimestamp (String timestamp) {this.timestamp = timestamp;

 }


}

The business that ② adds to the database is implemented according to its own needs.
③getrandomstr

Package com.wiimedia.utils;

Import Java.util.Random;

public class Getrandomstr {
 /**

 /Public String getrandomstring (int length) {
  String base = ' abcdefghijklmnopqrstuvwxyz0123456789 '; 
  Random Random = new Random (); 
  StringBuffer sb = new StringBuffer (); 
  for (int i = 0; i < length; i++) { 
   int number = Random.nextint (Base.length ()); 
   Sb.append (Base.charat (number)); 
  } 
  return sb.tostring (); 
  }

④signaturebean

Package com.wiimedia.utils;

public class Signaturebean {
 private String noncestr;
 Private String URL;
 Private String timestamp;
 Private String signature;
 Public String Getnoncestr () {return
  noncestr;
 }
 public void Setnoncestr (String noncestr) {
  this.noncestr = noncestr;
 }
 Public String GetUrl () {return
  URL;
 }
 public void SetUrl (String url) {
  this.url = URL;
 }
 Public String Gettimestamp () {return
  timestamp;
 }
 public void Settimestamp (String timestamp) {
  this.timestamp = timestamp;
 }
 Public String Getsignature () {return
  signature;
 }
 public void Setsignature (String signature) {
  this.signature = signature;
 }

}

⑤weixinutil

   Httpurlconn.setsslsocketfactory (SSF); 
   Httpurlconn.setdooutput (TRUE); 
   Httpurlconn.setdoinput (TRUE); 
   Httpurlconn.setusecaches (FALSE); 

   Set the request mode (Get/post) Httpurlconn.setrequestmethod (Requestmethod); 

   if ("Get". Equalsignorecase (Requestmethod)) Httpurlconn.connect (); 
    If the data needs to be submitted, if (null!= outputstr) {OutputStream outputstream = Httpurlconn.getoutputstream (); 
    Note the encoding format to prevent Chinese garbled outputstream.write (outputstr.getbytes ("UTF-8")); 
   Outputstream.close (); ///change the returned input stream to a string InputStream inputstReam = Httpurlconn.getinputstream (); 
   InputStreamReader InputStreamReader = new InputStreamReader (InputStream, "utf-8"); 

   BufferedReader BufferedReader = new BufferedReader (InputStreamReader); 
   String str = NULL; 
   while (str = Bufferedreader.readline ())!= null) {buffer.append (str); 
   } bufferedreader.close (); 
   Inputstreamreader.close ();

   InputStream = null; 
   Httpurlconn.disconnect (); 
  return buffer.tostring (); 
  catch (connectexception CE) {ce.printstacktrace ();
  catch (Exception e) {e.printstacktrace (); 
 Return "";

 }
}

At this point , the sharing function has been developed, but, in the generation of signature will encounter a lot of problems, here to provide some wx.config failure of the wrong way.

① confirm that the signature of your build is correct
In the http://mp.weixin.qq.com/debug/cgi-bin/sandbox?t=jsapisign provided by the micro-letter to verify

The noncestr used in ②wx.config, timestamp and the corresponding noncestr in the signature, timestamp is consistent ... As above (a. Server code)
(It is possible that the server-generated signature,noncestr,timestamp is not captured in Wx.config because of the order of JS page loading).

③ Confirmation URL is the full URL of the page, including the Get parameter section
Need to get rid of the back part of #

Whether the AppID in ④config is consistent with the AppID used to obtain Jsapi_ticket

⑤ Error {Errmsg:config:ok} is debug normal return turn off debug mode OK
Wx.config Debug:false,

The above is the entire content of this article, I hope to help you learn, but also hope that we support the cloud habitat community.
