Unable to send json string containing encoded string with curl in php - php

Question

I have created a script to send json data to a url
$data = array();
$key = 'mysecretkey';
$string = 'teststring';
$data['date'] = '2013-06-19 05:38:00';
$data['encrypted_string'] = mcrypt_encode($string,$key);
$data['id'] = 231;
$data['source_ref'] = 'testreference';
$data['status'] = 'Active';
header('Content-type: text/json');
header('Content-type: application/json');
$url = 'http://localhost/myproject/test/add_json_data';
$json_string = json_encode($data);
$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS,$json_string);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec( $ch );
mcrypt_encode encodes the string. Here is the json_string
{
"date": "2013-06-19 05:38:00",
"encrypted_string": "7Y4jqgIfhj25ghsF8yJ/qTtzXafTtIlwsz7xWIDVWJGoF22X2JbfSWfQtgmI1dYyyJDgs3nmaWctTEgKW5VmHw==",
"id": 231,
"source_ref": "testreference",
"status": "Active"
}
When i exe4cute the script nothing happens on the url i provided.
Here is what i am doing on the url.
function add_json_data()
{
$json = file_get_contents('php://input');
$obj = json_decode($json);
$this->load->helper('file');
write_file('json.json',$json);
}
I am using codeigniter so i am simply saving the post data in a file in json format to see what is coming. But i see the url is not called. I assume due to the encoded json string which contains encoded string it is not sending data to url. How can i send my encoded key to the url. I have also checked if i replace encrypted_string with something 'test' it is working fine. How can i send data to the url or any alternative? Please help.

Answer 1

Always turn on error_reporting when you're developing code, otherwise the simplest syntax error looks like a showstopping bug.
The line:
$string = 'teststring'
Is missing a semicolon.

Answer 2

I have found the answer for this. Here is how i can do this
$data = array();
$key = 'mysecretkey';
$string = 'teststring';
$data['date'] = '2013-06-19 05:38:00';
$data['encrypted_string'] = mcrypt_encode($string,$key);
$data['id'] = 231;
$data['source_ref'] = 'testreference';
$data['status'] = 'Active';
$url = 'http://localhost/myproject/test/add_json_data';
$json_string = json_encode($data);
$header[] = 'Content-type: text/json';
$header[] = 'Content-type: application/json';
$header[] = 'Content-Length: '.strlen($json_string);
$ch = curl_init( $url );
curl_setopt( $ch, CURLOPT_POST, 1);
curl_setopt( $ch, CURLOPT_POSTFIELDS,$json_string);
curl_setopt( $ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt( $ch, CURLOPT_HTTPHEADER,$header);
curl_setopt( $ch, CURLOPT_HEADER, 0);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec( $ch );
After setting header array and passing it to curl as an option it is working fine.
