如何使用PHP和curl发布JSON？

Question

I managed to get my request working in "Advanced Rest Client" using the following settings:

However, I tried to recreate the same request using PHP and I can't work out what I'm doing wrong. Here's what I have:

$config['key'] = "xxxxxxxxxxxx";
$config['clientid'] = xxxxxxxxx;

$url = 'http://xxxxxxxxxxxxxxxx.curdbee.com/invoices.json?api_token='.$config['key'];

$data = Array();  
$data['invoice']['client_id'] = $config['clientid'];

$data_string = json_encode($data);                                                                                   

$ch = curl_init($url);                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);                                                                                                                   

$result = curl_exec($ch);

echo curl_error($ch);

print_r($result);

Neither $result nor curl_error outputs anything and I can't work out why.

Answer 1

I just needed to add these two lines:

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

Answer 2

Try this

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url);                                                                      
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type: application/json',                                                                                
    'Content-Length: ' . strlen($data_string))                                                                       
);
