PHP micro-Credit public account development of the five pits (ii) _php example

The last article on the micro-letter public account of a few pits, the front five, has said the menu, the baby continues to repeat. Unfortunately, still do not know baby's baby in the end is not distressed baby, finished, I messy ...

Back to the point, we will not spit the other, the last article on the micro-letter menu, then, we now talk about the menu reply and so on.

The menu reply is the XML file that needs to be processed, and we can get the unique identification of each micro-letter user relative to the micro-public number based on the XML file returned by the micro-letter. The mechanism of the micro-trust public platform is simply that we will output the fixed format XML file, then the micro-mail app is responsible for parsing, getting the information we want, and then handling the information uniformly.

The sixth Pit, if you look at the micro-letter document, then, absolutely pits you, above the figure. Here's tousername and Fromusername must be clear, remember, do not write back, the user for micro-letter is a→b, then micro-letter for users is the opposite, seems to be clear now.

OK, plus your own logical code, is not the perfect implementation of the reply?

Seventh Pit, I really do not want to count, are you sure this reply is OK? Seriously, the baby is not sure, because you wrote after you know where to call it, my darling, Ni-ma, server verification by adding to the reply is the most insurance. I've lost my integrity.

So what are we going to say, let's talk about getting user information, because we're generally based on H5 pages. So, we need to use what we have previously configured

This dongdong, in fact, this relative to the front of at least a lot less pit, sincerely, the baby will not say he pits. Last code.

We need to call the time directly using the inside method, access to micro-letter Web page authorization, such as for a controller under the B view to obtain authorization, and to obtain the user's relevant information, then we can call directly, such as Getcodeurl (AppID, "http://" + Url + "/a/b "," Snsapi_userinfo ")

I'll just spit it out here.

eighth Pit, micro-letter menu JSON URL stitching, the front is not added JS verification mody, so, special Mody, or obediently plus http://.

However, after the authorization, because the user's a lot of information we have to use, this is the H5 page transfer value problem, I used in the project is the session, directly write a common method, if the session has a value, then directly take the value. For some of the inside, I would like to explain, not all the code will be posted, my side of the code is only I personally think need to post. So inside the method may have everybody to see, if need, can leave a message this baby, thank you.

public string getsession () {log.
 Error ("GetSession");
 String oauthstr = ""; try {if (Session!= null && (session["oauthstr"] = = NULL | | string. IsNullOrEmpty (session["Oauthstr"). ToString ())) {if (!string).
  IsNullOrEmpty (request.querystring["code"]) {Oauth2 OAuth = new Oauth2 ();
  String code = convert.tostring (request["Code"]); Oauthstr = OAuth.
   GetUserInfo (configurationmanager.appsettings["AppID"], configurationmanager.appsettings["AppSecret"], code);
  session["oauthstr"] = oauthstr;
  Tools.WAEntity.OAuthUser oauthuser = new Tools.WAEntity.OAuthUser ();
  Oauthuser = tools.jsonhelper.parsefromjson<tools.waentity.oauthuser> (OAUTHSTR);

 return oauthstr;
  else {Tools.WAEntity.OAuthUser Oauthuser = new Tools.WAEntity.OAuthUser (); Oauthuser = tools.jsonhelper.parsefromjson<tools.waentity.oauthuser> (session["OauthStr").
  ToString ()); return session["Oauthstr"].

 ToString (); } catch (Exception e) {log. Error (E.tostring ()); ReTurn oauthstr;

};

 }

And then every time I encounter a page that needs to get information, I usually call this on it.

Basically the rest is our own business logic to deal with, continue to say the pit.

The nineth Pit, the micro-letter upload picture, the pit is definitely not just yourself. Believe it or not, the baby really believes it. Special pictures cannot be uploaded for loops. Of course, this apple-only model, big Android is still no problem.
The first mentioned JS security verification problem, here is to invoke these authentication, request some permissions, and then get picture information and so on.

Rest assured that the baby is now talking on the map, no picture of a little brother Ah ...

Let's go back and look at the code.

Let's start with JSON.

public class Jsapi {JavaScriptSerializer Jss = new JavaScriptSerializer (); Public Jsapi () {} const string url_format_ticket = "https://api.weixin.qq.com/cgi-bin/ticket/getticket?access_token={

 0}&type=jsapi "; #region Verify JSAPI permissions configuration///<summary>///get JSAPI Permissions configuration array/Four parameters///</summary>///<param name= "Appid" > Application I
 d</param>///<param name= "Appsecret" > key </param>///<returns>json format four parameters </returns>

 public string Getjsapiinfo (string Appid, String appsecret) {string jsapi_ticket = ""; Ticket Cache 7,200 sec if (system.web.httpcontext.current.session["jsapi_ticket"] = = null) {string ticketurl = string. Format (Url_format_ticket, Basicapi.getaccesstoken (Appid, Appsecret));/"Https://api.weixin.qq.com/cgi-bin/ticket /getticket?access_token= "+ Getaccesstoken (Appid, Appsecret) +" &type=jsapi "Jsapi_ticket =
  Commonmethod.webrequestpostorget (Ticketurl, "");//basicapi.gettokensession System.web.httpcontext.current.session["Jsapi_ticket "] = Jsapi_ticket;
  System.Web.HttpContext.Current.Session.Timeout = 7200;


 Basicapi.writetxt ("Jsapi_ticket1:" + jsapi_ticket); else {jsapi_ticket = system.web.httpcontext.current.session["Jsapi_ticket"].
  ToString ();
 Basicapi.writetxt ("Jsapi_ticket2:" + jsapi_ticket);
 dictionary<string, object> respdic = (dictionary<string, object>) jss.deserializeobject (Jsapi_ticket); Jsapi_ticket = respdic["Ticket"]. ToString ();//gets ticket string timestamp = Commonmethod.convertdatetimeint (DateTime.Now). ToString ();//Generate signature timestamp string noncestr = Commonmethod.getrandcode (16);//generate signed random string url =
 System.Web.HttpContext.Current.Request.Url.AbsoluteUri.ToString ()//Current address basicapi.writetxt ("url:" + URL);
 String[] ArrayList = {"jsapi_ticket=" + jsapi_ticket, "timestamp=" + timestamp, "noncestr=" + noncestr, "url=" + URL};
 Array.Sort (ArrayList); String signature = String.
 Join ("&", ArrayList); Signature = Formsauthentication.hashpasswordforstoringinconfiGfile (Signature, "SHA1").
 ToLower (); String r = "{\" appid\ ": \" "+ appId +" \ "," timestamp\ ":" + timestamp + ", \" noncestr\ ": \" "+ Noncestr +" \ ", \" signature\ ": \" "+ signature +" \ "," jsapilist\ ": [\" chooseimage\ ", \" previewimage\ ", \" uploadimage\ ", \" downloadimage\ ", \"
 Scanqrcode\ ", \" Onmenushareqq\ "]}";
 Basicapi.writetxt ("R:" + R.replace ("", ""));

 Return R.replace ("", "");

 }

}

Then look at the specific call.

Background code is actually very simple, direct output configuration file, and then the front desk JS direct call can be.

Jsapi Jsapi = new Jsapi ();
string config = Jsapi.getjsapiinfo (appId, appsecret);
viewbag.config = config;

The front code, in fact, is not difficult, this has an official example.

<script type= "Text/javascript" > Wx.config (@Html. Raw (Viewbag.config))//Background micro-letter configuration file Wx.ready (function () {$ ("# Avatar "). Click (function () {wx.chooseimage ({count:1,//Picture quantity default 9 sizetype: [' compressed '],//can specify whether it is an artwork or a compression diagram, both of which are ' Original ', SourceType: [' album ', ' Camera '],//can specify whether the source is an album or a camera, both of which have success:function (res) {var localids = RES.L Ocalids; Returns a list of local IDs for the selected photos, localid can display pictures as the SRC attribute of the img tag wx.uploadimage ({localid: ' + localids, isshowprogresstips:1, Su
    Ccess:function (res) {ServerID = Res.serverid;

   Getwxphoto (ServerID);

  }

   });

 }

  });

 });

 });
 Wx.error (function (res) {alert ("Interface validation failed, details: \ n" + json.stringify (res));
 });
 var types = 1; function Getwxphoto (mediaId) {$.ajax ({async:false, type: "Post", url: "/activityregistration/downloadwxphoto",//
  Your own processing method data: {Mediaid:mediaid, types:types}, Success:function (data) {$ ("#imageico"). Val (Data.result);
  $ ("#hed_pic"). attr (' src ', "..." + data.result); $("#hed_pic"). attr (' Alt ', ' avatarimg ');

 }

 });

 } </script>

OK, the background method is actually very simple, is a binary file processing, not, simple egg, special Mody, because the path of the problem, pit the baby One hours, special mody. There are suggestions here, such as micro-letter pictures downloaded after the download to the front desk to load the picture, to ensure that each picture is loaded to complete, to ensure that the background of the upload of pictures completed.

Do not think that this is done, my darling, Avatar uploaded, micro-letter camera also special Mody call to call the baby is happy, the baby is also a cow, remember the front of the east, the baby has not said the pit.
To repeat our nineth pit, special, you JS write a for loop if you can cycle the picture uploaded to the background, the baby is convinced, really, the baby convinced.

Just say it, and in the end I thought for myself, also discussed with the team, probably because of the micro-letter verification, resulting in a photo upload after the success of a picture, but our iphone is a special case, big Android is no problem, the iphone is a problem, and the problem is not small, Upload four pictures bar, Lotte is the last one, finally, to find a universal netizen, thank you, but the baby has forgotten where to find, embarrassed ....
