Windows Azure Mobiles Services implements login registration for clients

The following is a simple implementation, with the client using the Android implementation as an example:

User table account:

Package Com.microsoft.ecodrive.model;public class Account {@com. Google.gson.annotations.SerializedName ("id") public string id; @com. Google.gson.annotations.SerializedName ("username") Public String username;@ Com.google.gson.annotations.SerializedName ("password") public String password; @Overridepublic boolean equals (Object O) {return o instanceof account && ((account) o). id = = ID;}}

First, login

1, the server new Api:login, the script is replaced by the following:

Exports.post = function (Request, response) {    //use ' Request.service ' to access features of your mobile service, e.g.:    //   var tables = request.service.tables;   var push = Request.service.push;    Response.send (Statuscodes.ok, {message: "POST"}); Exports.get = function (Request, response) {    var myTable = request.service.tables.getTable (' account ');    Mytable.where ({        username:request.param (' username '),        password:request.param (' Password ')    }). Read ({        success:checkpermissions    });    function Checkpermissions (results) {        if (results.length <= 0) {            response.send (statuscodes.bad_request, ' Not such user. ');        } else {            Response.send (Statuscodes.ok, {message: ' sucess. '});}}    ;

2, the client The login code is as follows:

private void Login (final string name,final string pwd) {list<pair<string, string>> parameters = new arraylist& Lt Pair<string, string>> ();p arameters.add (New pair<string, string> ("username", name));p Arameters.add ( New pair<string, string> ("password", pwd); MCLIENT.INVOKEAPI ("Login", "get", parameters, Apiresult.class, new Apioperationcallback<apiresult> () {        @Override public        void oncompleted (apiresult result, Exception Exception, servicefilterresponse response) {        int code = response.getstatus (). Getstatuscode (); LOG.I (TAG, "StatusCode:" +code); if (exception = = null) {showtoast ("Login sucess!");} else if (code==400) {showtoast ("Username or password is wrong, please try again."); Else{showtoast (Exception.getmessage ());}        }    );}

Note: Because it is taken from the project, some methods need to initialize themselves.

Second, registration

Method One: API mode

1, the server new Api:register, the script is replaced by the following:

exports.post    = function (Request, response) {var myTable = request.service.tables.getTable (' account ');    Mytable.where ({username:request.param (' username ')}). Read ({success:checkpermissions}); function Checkpermissions (results) {if (results.length <= 0) {var toinsert ={username:request.param            (' username '), password:request.param (' Password ')}; Mytable.insert (Toinsert, {success:function () {response.send (Statuscodes.ok, {MESSAG                E: ' Register sucess! '});        }            });            } else {Console.log (' User%s already exist. ', Request.param (' username '));        Response.send (statuscodes.bad_request, ' already exist. '); }}};exports.get = function (Request, response) {Response.send (Statuscodes.ok, {message: ' Hello world! '}); 

2, the client The code is as follows:

Use apiprivate void Register1 (final string name,final string pwd) {list<pair<string, string>> parameters = N EW arraylist<pair<string, string>> ();p arameters.add (New pair<string, string> ("username", name)); Parameters.Add (New pair<string, string> ("password", pwd)), Mclient.invokeapi ("register", "POST", parameters, Apiresult.class, New apioperationcallback<apiresult> () {        @Override public        void oncompleted (Apiresult result, Exception Exception, servicefilterresponse response) {        int code = response.getstatus (). Getstatuscode (); LOG.I (TAG, "StatusCode:" +code); if (exception = = null) {//sucessshowtoast (result.message);} else if (code==400) {showtoast (response.getcontent ());} Else{showtoast (Exception.getmessage ());}        }    );}

Method Two: Modify the Insert script for the Accout table.

1. Insert script to replace the Accout table is as follows:

function Insert (item, user, request) {    var permissionstable = tables.gettable (' account ');    Permissionstable.where ({        username:item.username    }). Read ({        success:checkpermissions    });    function Checkpermissions (results) {        if (results.length <= 0) {            request.execute ();        } else {            Console.log (' User%s already exist. ', item.username);            Request.respond (Statuscodes.bad_request, ' User already exist ');}}}

< Span style= "font-family: ' Comic Sans MS '; font-size:14px ">

Use insertprivate void Register (final String name,final string pwd) {Account account = new account (); account.username = Name;account.password = Pwd;maccounttable.insert (account,new tableoperationcallback<account> () {@ overridepublic void oncompleted (account result, Exception exception,servicefilterresponse response) {INT code = response . GetStatus (). Getstatuscode (); LOG.I (TAG, "StatusCode:" +code); if (exception = = null) {//sucessshowtoast ("Register sucess!");} else if (code==400) {showtoast (Response.getcontent (). replace ("\" "," "));} Else{showtoast (Exception.getmessage ());}});}

In addition, the Apiresult class is as follows:

Package Com.microsoft.ecodrive.model;import Com.google.gson.annotations.serializedname;public class APIResult {@ Serializedname ("Count") public    int mCount;    public int GetCount () {return mCount;} public String message;
