Windows Azure Mobiles Services implements the client's sign-in brochure

The following is just 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 to create a new api:login, the script to replace such as 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, ' No such user. ');        } else {            Response.send (Statuscodes.ok, {message: ' sucess. '});}}    ;

2. 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 was picked out from the project. Some methods need to be initialized themselves.

Ii. notes

Method One: API mode

1, the service side new Api:register. replace its script with the following example:

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, {message: ' 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. 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: Change the insert script for the Accout table.

1. Replace the Insert script for the Accout table with the following:

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 ');}}}    

2, client code such as the following:

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 ());}});}

Another, Apiresult class such as the following:

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;
