Sir,
What's the purpose of Image File Tagging ?

Friends,
I am using web service and forms for a number of situations in my project. But now when I try to use same strategy the data is not provided by the provider function. It gives ‘null’ value always. But I can see the value in chrome web console.

page.ts (controller)

call function this.getYearMaster(); in constructor

my controller function is

  getYearMaster() {
    this.projectplanprovider.getYearMaster()
    .then(data => {
      this.year = data;
      //console.log(this.data);
      alert("hi: "+this.year);
    });
  }

my provider function is

public getYearMaster() {
    const obj = {wsname: 'YearMaster' };
    const myData = JSON.stringify(obj);
    return new Promise((resolve, reject) => {
        console.log('will call the web service');

        const url = 'http://apps.xxx.gov.in/mobservice/index.php/yyy/';
        this.http.post(url, myData, { headers: new HttpHeaders(), responseType: 'json'})
        /*.map(res => {
          console.log('res1', res);             
          return res; // is this map needed, when it is returning the same value?
        })*/
        .subscribe(
          res => {
            console.log('res2', res);   
            resolve(res);
          }, 
          (err) => { 
            console.log('oops some error in Project Financial year selection'); 
            reject(err);
          }
        );
      });

  }

But I get on 'null' value as response ..

please advise

Thanks
Anes

Dear Friends,

With the Help of my Friend Vishnu A.R I solved the issue

my required Code is

<?php
$selectedTime = "2017-02-10 08:00,2017-02-10 07:00,2017-02-11 09:00";

$arr1 = explode(",", $selectedTime);

$arr2 = array();

foreach($arr1 as $time){
  $strtime = strtotime($time);
  $arr2[$strtime] = $time;
}
ksort($arr2); // sorting array in ascending order of key value
$arr3 = array();
foreach($arr2 as $key => $time){
  $timesplit = explode(" ", $time);

  $arr3[$timesplit[0]][] = array('start' => $timesplit[1]);
}
$output = json_encode($arr3);
var_dump($output);
?>

Thanks

Dear Friends,

I have a string with structure

$selectedTime = "2017-02-10 07:00,2017-02-10 08:00,2017-02-11 09:00";

I need to convert it as

{"2017-02-10":[{"start":"07:00"},{"start":"08:00"}],"2017-02-11":[{"start":"09:00"}]}

any idea ? please advise asap

Hi dear friends,
My current problem regarding inputstream value processing . I don't get the block level full value as shown in loop.I got last byte value only

           cipher.init(cipherMode, publicKey);
             byte[] encText = null;
            while ( (bufl = inputReader.read(buf)) != -1)
        {
             encText =  RSAEncryptUtil.encrypt(RSAEncryptUtil.copyBytes(buf,bufl),(PublicKey) publicKey);
         }

         String hexString = HexEncodeDecode.encode(encText);

I need to get encText byte[] value with full encrypted file value . Any body have a fast solution please..

Dear Friends,
I am looking for the topic "Virtualization techniques for Security" and got 3 points
1.Isolation and Protection of hypervisor from external entities
eg; Privileged management VMs
2. Recursive addition of additional virtualization layers
eg: by running commodity hypervisors on top of special "Secure" hypervisors
3. Through hardware trusted platform modules(TPMs)

I have not much idea abt these points . Do you can explain it

Hi pals,
I am looking to find a modulus calculation using my casio fx-991 ms calculator

i know how to find modulus using small numbers

eg: 7 mod 3 = 1. This because 7 = 3(2) + 1, in which 1 is the remainder. To do this process on a simple calculator do the following: Take the dividend (7) and divide by the divisor (3), note the answer and discard all the decimals -> example 7/3 = 2.3333333, only worry about the 2. Now multiply this number by the divisor (3) and subtract the resulting number from the original dividend. so 2*3 = 6, and 7 - 6 = 1, thus 1 is 7mod3

but i need to find

it's answer is 50

but when i do i don't get the full number in calculator it show 1.4500000x 10^34

but i don't know how to calculate mod use this type of result .

please advise me

Thanks

DEAR @SCHOL,
IN RSA ALGORITHM IT(e - public key) MUST BE USE PRIME NUMBER WHICH IS NOT THE CONFACTOR OF 'PHI'
Here we input (or randomly insert) two prime numbers p and q
n = pq
phi = (p-1)(q-1)
e = must be a prime number - which we chcek now in this thread - but not cofactor of phi

eg : if we give p = 11 & q = 3

then phi = 10*2 = 20

so we cannot give 5 for e , because it's cofactor of 'phi'(ie 20).
So the value e is a subset of PRIME Numbers .

We need to find the 'd' - Private key from formula

d*e mod phi = 1

Then if M is the Message to encrypt( Here M is integer value in range : 0<M<n)

C- Cipher text , which generate from M

C = M^e mod n[Encryption]

and

M = C^d mod n [Decryption]

This is the criteria(Condition) for RSA algorithm

Dear @vegas,

I am looking your 'Miller-Robin primality test'

Thnks,

Dear friends,
I am using wordpress for my activity logging purpose . I have a plugin for chart preparation ,

Dear Dani maam,
Do you Please give a cURL version of GET Verb REST call instead of the file_get_contents() method ? Waiting your reply

Thanks,
Anes

Dear pals,

I am newbie in RESTful services . I need to call a GET Verb in Server . I know 2 methods

1. Ajax Call

we can write it as

$.ajax({
         url: url, 
         dataType: "html",
         type: 'GET', 
         data: "id="+id+"&type="+type, 
         success: function(data){ 
            //$("#content").html(data); 
            alert(data);
            $('table #sample-boxed-2-pagination th a').each(function(){
                //this.href = this.href.replace(sub_url, main_url);
                var value = this.href.split('?');
                //alert(value[0]);
                if(value[0]!=sub_url)
                {
                  this.href = this.href.replace(value[0], sub_url);
                }
      });
         }

      });        
});

But I know it's not working in Cross domain scenario . Please advise a method to work same in all domains .

1. Using file_get_contents() function like

   $response = file_get_contents('https://kkl.com/graph/call?parm1=9');

I know I can call POST verb using cURL as

$ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, "http://localhost/simple_rest_master/test");
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);


    $data = array(
        'username' => 'foo',
        'password' => 'bar'
    );

    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

    $contents = curl_exec($ch);

    curl_close($ch);

    echo $contents;  // manipulate response

Do you can advise the syntax of GET call using cURL ?

Dear friends,
I am using the XML-RPC Server to implement a simple login authentication as a web service . So I wrote a function in wp-includes\class-wp-xmlrpc-server.php like

function web_auth($host, $db, $dbuser, $dbpass, $username, $password)
{
$dbhandle = mysql_connect($host, $dbuser, $dbpass) or die("Unable to connect to MySQL");
$selected = mysql_select_db($db,$dbhandle) or die("Could not select database");
//$md5_password = md5($password);
$md5_password = wp_hash_password($password);
$result = mysql_query("SELECT count(*) AS total FROM wp_users WHERE user_login='$username' AND user_pass='$md5_password' AND user_status=0");
$data=mysql_fetch_assoc($result);
//echo "SELECT count(*) AS total FROM wp_users WHERE user_login='$username' AND user_pass='$md5_password' AND user_status=0";
//die($data['total']);
if($data['total'] == 1)
{
return true;
}
return false;
}

But the password hash mechanism is not make things proper. Please help me to find the exact password in line

$md5_password = wp_hash_password($password);

Dear gusano,
Service layer is plugin internal functionality itself .
Currently I checked the case of only 1 plugin connection
with outside world , it's successful and the author of plugin offer more option in pro & ent version of that plugin . Gusano, my next unsurity is in how to implement OAuth2.0 in this setup.

Please advise

Thanks,
Anes

Dear Gusano,
Don't consider Web Service as a main concern , I plan to use the simple
REST API method described in URL Click Here & the plugin WPBI (Wordpress Business Intelligence) allow to communicate with an external plugin call .

So I feel there is no need for a framework for Web service .

please let me know your idea.

Thanks,
Anes

Dear Gusano,
My client need an architecture in which we can take a solution for our own system & for a web service . The Web service is for other web apps.
eg: If we do a plugin in our WP app its service can accessible to other systems through web service .

From my initial analysis I can found that putting a file in WP installation can call the plugin function . But need to tackle the database related connectivity etc....

Advise me

Thanks,
Anes

Thanks @pritaeas,@cwarn ,
I will check the PHP OAuth 2.0 provided by pritaeas.

Dear Pritaes,
I am just start to work on it . My Concern is how I can implement OAuth2.0 authentication . I am looking RFC specification at IETF . May I use any other JS library like Node.js for this purpose ? Please advise the steps I need to follow.

Thanks,
Anes

Dear Friends,
I am using Simple-REST Library for my REST Web service purpose . I need to integrate "OAuth2" with my REST API skeleton.
I attached the REST - API Client & Server for your reference . Please check it and help me with a good solution for implementation.

Thanks,
Anes

Dear dingoellis,
I create a new file as u suggest now , rough checked feel it include ALL files content . I will test that in my office and let you know result. I attach my resultant js of (utils.js, tooltip.js, lineChart.js, legend.js, discreteBar.js,discreteBarChart.js , axis.js)
as common.js here

Thanks,
Anes

Dear dingoellis,almostbob:
I can understand the case of jQuery , I plan to make it as separate in CDN . that's good . So only 7 files need to make single one . i.e utils.js, tooltip.js, lineChart.js, legend.js, discreteBar.js,discreteBarChart.js , axis.js from the attached file list .

May I test it and give feedback .

Thanks alot @dingoellos & @almostbob

Anes

Dear dingoellis,
any way it's not problem of used files . For your reference I attach all the
files with this post . please check and advise me .

Thanks,
Anes

Dear dingoellis,
I check your URL and test . I have 11 js files so I upload all and try . But I got a very small file and it's not included the content of jQuery and some other files . When I test the code using that JS got error of "undefined" stuffs . So I believe it's not good for multiple files .

Please advise .

Dear friends,
I am using Wordpress 3.6 for my current development . But my client need a system which has independent

• View Layer

from my analysis I can found that Wordpress has a

**Theme ---- View+DB layer **

and cannot Identify a service layer.

Please advise me with a solution.
