PHP cURL HTTP GET XML Format - php

I have an application that has a Web Services RESTful API. When I make HTTP GET requests in the browser I get XML responses back.
When I make the same request using PHP I get the correct information but it is not formatted in XML and so I can't pass it to Simple XML.
Here's my code.
<?php
//Deifne user credentials to use with requests
$user = "user";
$passwd = "user";
//Define header array for cURL requestes
$header = array('Contect-Type:application/xml', 'Accept:application/xml');
//Define base URL
$url = 'http://192.168.0.100:8080/root/restful/';
//Define http request nouns
$ls = $url . "landscapes";
//Initialise cURL object
$ch = curl_init();
//Set cURL options
curl_setopt_array($ch, array(
CURLOPT_HTTPHEADER => $header, //Set http header options
CURLOPT_URL => $ls, //URL sent as part of the request
CURLOPT_HTTPAUTH => CURLAUTH_BASIC, //Set Authentication to BASIC
CURLOPT_USERPWD => $user . ":" . $passwd, //Set username and password options
CURLOPT_HTTPGET => TRUE //Set cURL to GET method
));
//Define variable to hold the returned data from the cURL request
$data = curl_exec($ch);
//Close cURL connection
curl_close($ch);
//Print results
print_r($data);
?>
Any thoughts or suggestions would be really helpful.

EDIT:
So this is the response I get from the PHP code:
0x100000rhel-mlsptrue9.2.3.0101
This is the response if I use the WizTools Rest Client or a browser.
<?xml version="1.0" encoding="UTF-16"?>
<landscape-response total-landscapes="1" xmlns="http://www.url.com/root/restful/schema/response">
<landscape>
<id>0x100000</id>
<name>rhel-mlsp</name>
<isPrimary>true</isPrimary>
<version>9.2.3.010</version>
</landscape>
</landscape-response>
As you can see the information is there but the PHP is not really presenting this in a useful way.

I was able to find the answer to this question so I thought I would share the code here.
//Initialise curl object
$ch = curl_init();
//Define curl options in an array
$options = array(CURLOPT_URL => "http://192.168.0.100/root/restful/<URI>",
CURLOPT_PORT => "8080",
CURLOPT_HEADER => "Content-Type:application/xml",
CURLOPT_USERPWD => "<USER>:<PASSWD>",
CURLOPT_HTTPAUTH => CURLAUTH_BASIC,
CURLOPT_RETURNTRANSFER => TRUE
);
//Set options against curl object
curl_setopt_array($ch, $options);
//Assign execution of curl object to a variable
$data = curl_exec($ch);
//Close curl object
curl_close($ch);
//Pass results to the SimpleXMLElement function
$xml = new SimpleXMLElement($data);
print_r($xml);
As you can see the code is not all that different, the main thing was separating the port option out of the URL and into its own option.
Hopefully this helps someone else out!!!

Try this
$resp = explode("\n<?", $data);
$response = "<?{$resp[1]}";
$xml = new SimpleXMLElement($response);
Does it print anything at all (your code)? Try using echo $data but hit F12 to view the results on the console.

Get data from XML sites

I want to get some data from a site based on xml's.
The problem is I need to be logged to it as a PublicUser without password.
I have tryed:
$url = 'http://IP/wcd/system_counter.xml';
$content = file_get_contents($url);
echo $content
But i only get this:
err En ReloginAttempt /wcd/index.html false
This is the xml code used for loggin:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet href="top.xsl" type="text/xsl"?>
<MFP>
<SelNo>Auto</SelNo>
<LangNo>En</LangNo>
<Service><Setting><AuthSetting><AuthMode><AuthType>None</AuthType>
<ListOn>false</ListOn>
<PublicUser>true</PublicUser>
<BoxAdmin>false</BoxAdmin>

<MiddleServerSetting><ControlList><ArraySize>0</ArraySize></ControlList><Screen>
<Id>0</Id></Screen></MiddleServerSetting>
</Setting></Service><LangDummy>false</LangDummy></MFP>
Is there a way to send the user as well when i want to get the XML info ?
You cannot access pages requiring posted login information using file_get_contents. Instead you need to use curl. Something along these lines:
$ch = curl_init($url); // The url you want to call
curl_setopt_array(
$ch, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => $login_xml, // The xml login in string form
)
);
//getting response from server
$response = curl_exec($ch);
echo curl_error($ch);
curl_close($ch);

YQL : Getting unsupported http protocol error

When i'm trying to invoke the YQL via cURL i'm getting the following error.
HTTP Version Not Supported
Description: The web server "engine1.yql.vip.bf1.yahoo.com" is using an unsupported version of the HTTP protocol.
Following is the code used
// URL
$URL = "https://query.yahooapis.com/v1/public/yql?q=select * from html where url=\"http://www.infibeam.com/Books/search?q=9788179917558\" and xpath=\"//span[#class='infiPrice amount price']/text()\"&format=json";
// set url
curl_setopt($ch, CURLOPT_URL, $URL);
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
echo $output;
?>
Invoking the same URL from thr browser works fine
https://query.yahooapis.com/v1/public/yql?q=select * from html where
url="http://www.infibeam.com/Books/search?q=9788179917558" and
xpath="//span[#class='infiPrice amount price']/text()"&format=json
Can someone please point me what is wrong in the code?
The problem is probably caused because the url you feed to cURL is not valid. You need to prepare / encode the individual values of the query strings for use in a url.
You can do that using urlencode():
$q = urlencode("select * from html where url=\"http://www.infibeam.com/Books/search?q=9788179917558\" and xpath=\"//span[#class='infiPrice amount price']/text()\"");
$URL = "https://query.yahooapis.com/v1/public/yql?q={$q}&format=json";
In this case I have only encoded the value of q as the format does not contain characters that you cannot use in a url, but normally you'd do that for any value you don't know or control.
Okay I gottacha .. The problem was with the https. Used the following snippet for debug
if (false === ($data = curl_exec($ch))) {
die("Eek! Curl error! " . curl_error($ch));
}
Added below code to accept SSL certificates by default.
$options = array(CURLOPT_URL => $URL,
CURLOPT_HEADER => "Content-Type:text/xml",
CURLOPT_SSL_VERIFYPEER => 0,
CURLOPT_RETURNTRANSFER => TRUE
);
Complete code is here
<?php
// create curl resource
$ch = curl_init();
// URL
$q = urlencode("select * from html where url=\"http://www.infibeam.com/Books/search?q=9788179917558\" and xpath=\"//span[#class='infiPrice amount price']/text()\"");
$URL = "https://query.yahooapis.com/v1/public/yql?q={$q}&format=json";
echo "URL is ".$URL;
$ch = curl_init();
//Define curl options in an array
$options = array(CURLOPT_URL => $URL,
CURLOPT_HEADER => "Content-Type:text/xml",
CURLOPT_SSL_VERIFYPEER => 0,
CURLOPT_RETURNTRANSFER => TRUE
);
//Set options against curl object
curl_setopt_array($ch, $options);
//Assign execution of curl object to a variable
$data = curl_exec($ch);
echo($data);
//Pass results to the SimpleXMLElement function
//$xml = new SimpleXMLElement($data);
echo($data);
if (false === ($data = curl_exec($ch))) {
die("Eek! Curl error! " . curl_error($ch));
}
if (200 !== (int)curl_getinfo($ch, CURLINFO_HTTP_CODE)) {
die("Oh dear, no 200 OK?!");
}
//Close curl object
curl_close($ch);
?>

Send AJAX-like post request using PHP only

I'm currently working on some automatization script in PHP (No HTML!).
I have two PHP files. One is executing the script, and another one receive $_POST data and returns information.
The question is how from one PHP script to send POST to another PHP script, get return variables and continue working on that first script without HTML form and no redirects.
I need to make requests a couple of times from first PHP file to another under different conditions and return different type of data, depending on request.
I have something like this:
<?php // action.php (first PHP script)
/*
doing some stuff
*/
$data = sendPost('get_info');// send POST to getinfo.php with attribute ['get_info'] and return data from another file
$mysqli->query("INSERT INTO domains (id, name, address, email)
VALUES('".$data['id']."', '".$data['name']."', '".$data['address']."', '".$data['email']."')") or die(mysqli_error($mysqli));
/*
continue doing some stuff
*/
$data2 = sendPost('what_is_the_time');// send POST to getinfo.php with attribute ['what_is_the_time'] and return time data from another file
sendPost('get_info' or 'what_is_the_time'){
//do post with desired attribute
return $data; }
?>
I think i need some function that will be called with an attribute, sending post request and returning data based on request.
And the second PHP file:
<?php // getinfo.php (another PHP script)
if($_POST['get_info']){
//do some actions
$data = anotherFunction();
return $data;
}
if($_POST['what_is_the_time']){
$time = time();
return $time;
}
function anotherFunction(){
//do some stuff
return $result;
}
?>
Thanks in advance guys.
Update: OK. the curl method is fetching the output of php file. How to just return a $data variable instead of whole output?
You should use curl. your function will be like this:
function sendPost($data) {
$ch = curl_init();
// you should put here url of your getinfo.php script
curl_setopt($ch, CURLOPT_URL, "getinfo.php");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$result = curl_exec ($ch);
curl_close ($ch);
return $result;
}
Then you should call it this way:
$data = sendPost( array('get_info'=>1) );
I will give you some example class , In the below example you can use this as a get and also post call as well. I hope this will help you.!
/*
for your reference . Please provide argument like this,
$requestBody = array(
'action' => $_POST['action'],
'method'=> $_POST['method'],
'amount'=> $_POST['amount'],
'description'=> $_POST['description']
);
$http = "http://localhost/test-folder/source/signup.php";
$resp = Curl::postAuth($http,$requestBody);
*/
class Curl {
// without header
public static function post($http,$requestBody){
$curl = curl_init();
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $http ,
CURLOPT_USERAGENT => 'From Front End',
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => $requestBody
));
// Send the request & save response to $resp
$resp = curl_exec($curl);
// Close request to clear up some resources
curl_close($curl);
return $resp;
}
// with authorization header
public static function postAuth($http,$requestBody,$token){
if(!isset($token)){
$resposne = new stdClass();
$resposne->code = 400;
$resposne-> message = "auth not found";
return json_encode($resposne);
}
$curl = curl_init();
$headers = array(
'auth-token: '.$token,
);
// Set some options - we are passing in a useragent too here
curl_setopt_array($curl, array(
CURLOPT_HTTPHEADER => $headers ,
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_URL => $http ,
CURLOPT_USERAGENT => 'From Front End',
CURLOPT_POST => 1,
CURLOPT_POSTFIELDS => $requestBody
));
// Send the request & save response to $resp
$resp = curl_exec($curl);
// Close request to clear up some resources
curl_close($curl);
return $resp;
}
}

Api in PHP - Accept a curl request and process

Not sure if anyone can help me out with a question.
I had to write some php for the company I work for that lets us integrate with an API that accepts a JSON body. I used the cUrl method, and the script is working great.
If I wanted to build another php page that would accept the request im sending, how would I go about this?
Say I wanted to allow someone to send this same request to me, and then wanted the info they sent to go into my database, how would turn their request into php strings?
Here is the code im sending.
<?
$json_string = json_encode(array("FirstName" => $name, "MiddleName" => " ", "LastName" => $last));;
// echo $json_string;
// jSON URL which should be requested
$json_url = 'http://www.exampleurl.com';
// jSON String for request
// Initializing curl
$ch = curl_init( $json_url );
// Configuring curl options
$options = array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array(
'Accept: application/json;charset=utf-8',
'Content-Type: application/json;charset=utf-8',
'Expect: 100-continue',
'Connection: Keep-Alive') ,
CURLOPT_POSTFIELDS => $json_string
);
// Setting curl options
curl_setopt_array( $ch, $options );
// Getting results
$result = curl_exec($ch); // Getting jSON result string
echo $result;
$myArray = json_decode($result);
$action = $myArray->Action;
?>
To get the raw data from the POST that you would be receiving you would use $postData = file_get_contents('php://input');
http://php.net/manual/en/reserved.variables.post.php
Then you would json_decode() the contents of that POST back into JSON.
http://php.net/manual/en/function.json-decode.php
Not really good understood your question. May be you are looking for the way to read raw POST data? In that case open and read from php://stdin stream.
$stdin = fopen('php://stdin', 'r');
By the way read here ( http://php.net/manual/en/function.curl-setopt.php ) how to use CURLOPT_POSTFIELDS. This parameter can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value.

Getting JSON response with PHP

I'm trying to connect an API that uses 0AUTH2 via PHP. The original plan was to use client-side JS, but that isn't possible with 0AUTH2.
I'm simply trying get a share count from the API's endpoint which is here:
https://api.bufferapp.com/1/links/shares.json?url=[your-url-here]&access_token=[your-access-key-here]
I do have a proper access_token that I am using to access the json file, that is working fine.
This is the code I have currently written, but I'm not even sure I'm on the right track.
// 0AUTH2 ACCESS TOKEN FOR AUTHENTICATION
$key = '[my-access-key-here]';
// JSON URL TO BE REQUESTED
$json_url = 'https://api.bufferapp.com/1/links/shares.json?url=http://bufferapp.com&access_token=' . $key;
// GET THE SHARE COUNT FROM THE REQUEST
$json_string = '[shares]';
// INITIALIZE CURL
$ch = curl_init( $json_url );
// CONFIG CURL OPTIONS
$options = array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array('Content-type: application/json') ,
CURLOPT_POSTFIELDS => $json_string
);
// SETTING CURL AOPTIONS
curl_setopt_array( $ch, $options );
// GET THE RESULTS
$result = curl_exec($ch); // Getting jSON result string
Like I said, I don't know if this is the best method - so I'm open to any suggestions.
I'm just trying to retrieve the share count with this PHP script, then with JS, spit out the share count where I need it on the page.
My apologies for wasting anyone's time. I have since been able to work this out. All the code is essentially the same - to test to see if you're getting the correct response, just print it to the page. Again, sorry to have wasted anyones time.
<?php
// 0AUTH2 ACCESS TOKEN FOR AUTHENTICATION
$key = '[your_access_key_here]';
// URL TO RETRIEVE SHARE COUNT FROM
$url = '[your_url_here]';
// JSON URL TO BE REQUESTED - API ENDPOINT
$json_url = 'https://api.bufferapp.com/1/links/shares.json?url=' . $url . ' &access_token=' . $key;
// GET THE SHARE COUNT FROM THE REQUEST
$json_string = '[shares]';
// INITIALIZE CURL
$ch = curl_init( $json_url );
// CONFIG CURL OPTIONS
$options = array(
CURLOPT_RETURNTRANSFER => true,
CURLOPT_HTTPHEADER => array('Content-type: application/json') ,
CURLOPT_POSTFIELDS => $json_string
);
// SETTING CURL AOPTIONS
curl_setopt_array( $ch, $options );
// GET THE RESULTS
$result = curl_exec($ch); // Getting jSON result string
print $result;
?>
