How to generate new address for blockchain wallet

0 votes

I am trying to generate new address for each wallet using blockchain API using the following code:

<?php

$guid = "7c74bb77-4e25-4eea-a9d3-df1cf6a9d218";

$main_password = "******";

$label = "firsttym";

$json_url = "http://localhost:3000/merchant/$guid/new_address?

password = $main_password & label = $label";

$json_data = file_get_contents($json_url);

$json_feed = json_decode($json_data ,true);

$message = $json_feed->message;

$txid = $json_feed->tx_hash;

?>

I get the following error:

Warning: file_get_contents(localhost:3000/merchant/7c74bb77-4e25-4eea??-a9d3-df1cf6a9d218/…??) [function.file-get-contents]: failed to open stream:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

in C:\wamp\www\block\first.php on line 8

Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\www\block\first.php on line 8

How to solve this?

You can use the following to generate wallet addresses. 
Start the blockchain before making the request using this code:

blockchain-wallet-service start --port 3000

then use the following code:

$url = "http://localhost:3000/merchant/$guid/new_address?password=$password&label=$label";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);

   $data = json_decode(curl_exec($ch), TRUE);

   return $data;
