How to use 'Curl' in php to send data to android - php

I have a listener in an android application to detect messages sent by the server php
public class Threa implements Runnable
{
public static final String SERVERIP = "192.168.1.4";
public static final int SERVERPORT =6060 ; //4444
public BufferedReader in;
public int x=0;
public void run() {
try {
ServerSocket serverSocket = new ServerSocket(SERVERPORT);
while (true)
{
x++;
Socket client = serverSocket.accept();
try {
in = new BufferedReader(new InputStreamReader(client.getInputStream()));
String str = in.readLine();
} catch(Exception e) {
} finally {
client.close();
}
}
} catch (Exception e) {
}
}
}
I found this code on the Internet
function get_url($url)
{
$ch = curl_init();
if($ch === false)
{
die('Failed to create curl object');
}
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
echo get_url('http://www.apple.com/');
using cURL in php to send the message is correct, if not what is the solution to solve this problem, please give me an idea

curl is good to communicate using protocols such as http/ftp etc..
If you want to send random data (ie: using your very own protocol), then you should use php sockets they are made for that :

CURL Post Request to API Looping Through Database

I've been trying to select values (students data) from mysql database table and looping through database to send to an API using PHP CURL Post request but it's not working.
This is the API body:
{
"students":[
{
"admissionNumber": "2010",
"class":"js one"
},
{
"admissionNumber": "2020",
"class":"ss one"
}
],
"appDomain":"www.schooldomain.com"
}
Parameters I want to send are "admissionNumber" and "class" parameters while "appDomain" is same for all. Here's my code:
if(isset($_POST['submit'])){
$body = "success";
$info = "yes";
class SendDATA
{
private $url = 'https://url-of-the-endpoint';
private $username = '';
private $appDomain = 'http://schooldomain.com/';
// public function to commit the send
public function send($admNo,$class)
{
$url_array= array('admissionNumber'=>$admNo,'class'=>$class,'appDomain'=>$this-> appDomain);
$url_string = $data = http_build_query($url_array);
// using the curl library to make the request
$curlHandle = curl_init();
curl_setopt($curlHandle, CURLOPT_URL, $this->url);
curl_setopt($curlHandle, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curlHandle, CURLOPT_POSTFIELDS, $url_string);
curl_setopt($curlHandle, CURLOPT_POST, 1);
$responseBody = curl_exec($curlHandle);
$responseInfo = curl_getinfo($curlHandle);
curl_close($curlHandle);
return $this->handleResponse($responseBody,$responseInfo);
}
private function handleResponse($body,$info)
{
if ($info['http_code']==200){ // successful submission
$xml_obj = simplexml_load_string($body);
// extract
return true;
}
else{
// error handling
return false;
}
}
}
$sms = new SendDATA();
$result = mysqli_query( $mysqli, "SELECT * FROM school_kids");
while ($row = mysqli_fetch_array($result)) {
$admNo = $row['admNo'];
$class = $row['class'];
$sms->send($admNo,$class,"header");
echo $admNo. " ".$class;
}
}
The question is rather unclear; when you say "this is the API body", I presume this JSON fragment is what the REST API at https://url-of-the-endpoint expects. If so, you are building your request body wrong. http_build_query creates an URL-encoded form data block (like key=value&anotherKey=another_value), not a JSON. For a JSON, here's what you want:
$data = array('students' => array
(
array('admissionNumber' => $admNo, 'class' => $class)
),
'appDomain':$this->appDomain
);
$url_string = $data = json_encode($data);
Also, you probably want to remove the HTTP headers from the response:
curl_setopt($curlHandle, CURLOPT_HEADER, false);

Authorization HTTP header with ASP.NET

I want to create an authorization http header using asp.net i have the code given in documentation if i want to do it using php+ curl here is the link http://help.voxeo.com/go/help/evolution.sms.postapi .
I dont want to install php on my IIS and want to work purely in .net environment . Can some one give asp alternative to following code :
$botkey='[999999]';
$from="14075551212";
$userKey = $_REQUEST['userkey'];
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://api.messaging.staging.voxeo.net/1.0/messaging');
curl_setopt($ch, CURLOPT_HEADER, 0);
$data="botkey=".$botkey."&apimethod=send&msg=".$msg."&userkey=".$userKey."&network=SMS& from=".$from;
curl_setopt($ch, CURLOPT_USERPWD, '[Evolution User Name]:[Evolution Password]');
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
c url_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
I need ASP.net alternative to below curl
curl -u MyUserName:MyPassword "http://api.messaging.staging.voxeo.net/1.0/messaging" -X POST -d "botkey=12345&apimethod=send&msg=My%20test%20message.&user=14075555555&network=SMS&from=14076666666"
I'm not sure I understand you completely but this is something I had to do to allow flash to get to a secure section of my app. I have more checks in place which I have removed for sake of clarity but this will create an authorisation cookie if this is what you need. I must ask though, why can't you use the normal authentication methods in ASP.NET?
void Application_BeginRequest(object sender, EventArgs e)
{
string SessionParamName = "";
string SessionCookieName = "";
string AuthParamName = "";
string AuthCookieName = "";
try
{
SessionParamName = "ASPSESSID";
SessionCookieName = "ASP.NET_SessionId";
if (HttpContext.Current.Request.Form[SessionParamName] != null)
UpdateCookie(SessionCookieName, HttpContext.Current.Request.Form[SessionParamName]);
else if (HttpContext.Current.Request.QueryString[SessionParamName] != null)
UpdateCookie(SessionCookieName, HttpContext.Current.Request.QueryString[SessionParamName]);
}
catch { }
try
{
AuthParamName = "AUTHID";
AuthCookieName = FormsAuthentication.FormsCookieName;
if (HttpContext.Current.Request.Form[AuthParamName] != null)
UpdateCookie(AuthCookieName, HttpContext.Current.Request.Form[AuthParamName]);
else if (HttpContext.Current.Request.QueryString[AuthParamName] != null)
UpdateCookie(AuthCookieName, HttpContext.Current.Request.QueryString[AuthParamName]);
}
catch { }
}
private void UpdateCookie(string CookieName, string CookieValue)
{
HttpCookie Cookie = HttpContext.Current.Request.Cookies.Get(CookieName);
if (Cookie == null)
Cookie = new HttpCookie(CookieName);
Cookie.Value = CookieValue;
HttpContext.Current.Response.Cookies.Add(Cookie);
}

Gotomeeting php api(oauth) implementation

I am trying to create a php gotomeating api implementation. I successfully got the access_token but for any other requests I get error responses. This is my code:

$domain = $_SERVER['HTTP_HOST'];
$base = "/oauth/index.php";
$base_url = urlencode("http://$domain$base");
$OAuth_url = "https://api.citrixonline.com/oauth/authorize?client_id=$key&redirect_uri=$base_url";
$OAuth_exchange_keys_url = "http://api.citrixonline.com/oauth/access_token?grant_type=authorization_code&code={responseKey}&client_id=$key";
if($_SESSION['access_token']) CreateForm();else
if($_GET['send']) OAuth_Authentication($OAuth_url);
elseif($_GET['code']) OAuth_Exchanging_Response_Key($_GET['code'],$OAuth_exchange_keys_url);
function OAuth_Authentication ($url){
$_SESSION['access_token'] = false;
header("Location: $url");
}
function CreateForm(){
$data = getURL('https://api.citrixonline.com/G2M/rest/meetings?oauth_token='.$_SESSION['access_token'],false);
}
function OAuth_Exchanging_Response_Key($code,$url){

if(IsJsonString($data)){
$data = json_decode($data);
$_SESSION['access_token'] = $data->access_token;
CreateForm();
}else{
echo 'error';
}
}
/*

function IsJsonString($str){
try{
$jObject = json_decode($str);
}catch(Exception $e){
return false;
}
return (is_object($jObject)) ? true : false;
}
/*

function getURL($url,$auth_token = false,$data=false){
// Initialize session and set URL.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
// Set so curl_exec returns the result instead of outputting it.
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
if($auth_token){
curl_setopt($curl, CURLOPT_HTTPHEADER, array('Authorization: OAuth oauth_token='.$auth_token));
}
if($data){
curl_setopt($ch, CURLOPT_POST,true);
$d = json_encode('{ "subject":"test", "starttime":"2011-12-01T09:00:00Z", "endtime":"2011-12-01T10:00:00Z", "passwordrequired":false, "conferencecallinfo":"test", "timezonekey":"", "meetingtype":"Scheduled" }');
echo implode('&', array_map('urlify',array_keys($data),$data));
echo ';';
curl_setopt($ch, CURLOPT_POSTFIELDS,
implode('&', array_map('urlify',array_keys($data),$data))
);
}
// Get the response and close the channel.
$response = curl_exec($ch);
/*
* if redirect, redirect
*/
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
if ($code == 301 || $code == 302) {
preg_match('/<a href="(.*?)">/', $response, $matches);
$newurl = str_replace('&','&',trim(array_pop($matches)));
$response = getURL($newurl);
} else {
$code = 0;
}
curl_close($ch);
return $response;
}
function urlify($key, $val) {
return urlencode($key).'='.urlencode($val);
}
to start the connect process you need to make a request to the php file fith send=1. I tryed diffrent atempts to get the list of meetings but could not get a good response.
Did anybody had prev problems with this or know of a solution for this?
Edit:
This is not a curl error, the server responds with error messages, in the forums from citrix they say it should work, no further details on why it dosen't work, if I have a problem with the way I implemented the oauth or the request code. The most comon error I get is: "error code:31305" that is not documented on the forum.
[I also posted this on the Citrix Developer Forums, but for completeness will mention it here as well.]
We are still finalizing the documentation for these interfaces and some parameters which are written as optional are actually required.
Compared to your example above, changes needed are:
set timezonekey to 67 (Pacific time)
set passwordrequired to false
set conferencecallinfo to Hybrid (meaning: both PSTN and VOIP will be provided)
Taking those changes into account, your sample data would look more like the following:
{"subject":"test meeting", "starttime":"2012-02-01T08:00:00",
"endtime":"2012-02-01T09:00:00", "timezonekey":"67",
"meetingtype":"Scheduled", "passwordrequired":"false",
"conferencecallinfo":"Hybrid"}

How use CURLOPT_WRITEFUNCTION when download a file by CURL

My Class for download file direct from a link:
MyClass{
function download($link){
......
$ch = curl_init($link);
curl_setopt($ch, CURLOPT_FILE, $File->handle);
curl_setopt($ch,CURLOPT_WRITEFUNCTION , array($this,'__writeFunction'));
curl_exec($ch);
curl_close($ch);
$File->close();
......
}
function __writeFunction($curl, $data) {
return strlen($data);
}
}
I want know how to use CRULOPT_WRITEFUNCTION when download file.
Above code if i remove line:
curl_setopt($ch,CURLOPT_WRITEFUNCTION , array($this,'__writeFunction'));
Then it will run good, i can download that file.But if i use CURL_WRITEFUNCTION option i can't download file.
I know this is an old question, but maybe my answer will be of some help for you or someone else. Try this:
function get_write_function(){
return function($curl, $data){
return strlen($data);
}
}
I don't know exactly what you want to do, but with PHP 5.3, you can do a lot with the callback. What's really great about generating a function in this way is that the values passed through the 'use' keyword remain with the function afterward, kind of like constants.
function get_write_function($var){
$obj = $this;//access variables or functions within your class with the object variable
return function($curl, $data) use ($var, $obj) {
$len = strlen($data);
//just an example - you can come up with something better than this:
if ($len > $var){
return -1;//abort the download
} else {
$obj->do_something();//call a class function
return $len;
}
}
}
You can retrieve the function as a variable as follows:
function download($link){
......
$var = 5000;
$write_function = $this->get_write_function($var);
$ch = curl_init($link);
curl_setopt($ch, CURLOPT_FILE, $File->handle);
curl_setopt($ch, CURLOPT_WRITEFUNCTION , $write_function);
curl_exec($ch);
curl_close($ch);
$File->close();
......
}
That was just an example. You can see how I used it here: Parallel cURL Request with WRITEFUNCTION Callback. I didn't actually test all of this code, so there may be minor errors. Let me know if you have problems, and I'll fix it.
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_BUFFERSIZE, 8096);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, 'http://blog.ronnyristau.de/wp-content/uploads/2008/12/php.jpg');
$content = curl_exec($ch);
curl_close($ch);
$out = fopen('/tmp/out.png','w');
if($out){
fwrite($out, $content);
fclose($out);
}
Why do you use curl to download a file? Is there a special reason? You can simply use fopen and fread
I have written a small class for it.
<?php
class Utils_FileDownload {
private $source;
private $dest;
private $buffer;
private $overwrite;
public function __construct($source,$dest,$buffer=4096,$overwrite=false){
$this->source = $source;
$this->dest = $dest;
$this->buffer = $buffer;
$this->overwrite = $overwrite;
}
public function download(){
if($this->overwrite||!file_exists($this->dest)){
if(!is_dir(dirname($this->dest))){mkdir(dirname($this->dest),0755,true);}
if($this->source==""){
$resource = false;
Utils_Logging_Logger::getLogger()->log("source must not be empty.",Utils_Logging_Logger::TYPE_ERROR);
}
else{ $resource = fopen($this->source,"rb"); }
if($this->source==""){
$dest = false;
Utils_Logging_Logger::getLogger()->log("destination must not be empty.",Utils_Logging_Logger::TYPE_ERROR);
}
else{ $dest = fopen($this->dest,"wb"); }
if($resource!==false&&$dest!==false){
while(!feof($resource)){
$read = fread($resource,$this->buffer);
fwrite($dest,$read,$this->buffer);
}
chmod($this->dest,0644);
fclose($dest); fclose($resource);
return true;
}else{
return false;
}
}else{
return false;
}
}
}
It seems like cURL uses your function instead of writing to the request once CURLOPT_WRITEFUNCTION is specified.
So the correct solution would be :
MyClass{
function download($link){
......
$ch = curl_init($link);
curl_setopt($ch, CURLOPT_FILE, $File->handle);
curl_setopt($ch,CURLOPT_WRITEFUNCTION , array($this,'__writeFunction'));
curl_exec($ch);
curl_close($ch);
$File->close();
......
}
function __writeFunction($curl, $data) {
echo $data;
return strlen($data);
}
}
This can also handle binary files as well.
