如何使用PHP和curl发布JSON？

Question

我设法使用以下设置让我的请求在“Advanced Rest Client”中工作：

但是，我尝试使用PHP重新创建相同的请求，但我无法弄清楚我做错了什么。这就是我所拥有的：

$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);

$ result和curl_error都没有输出任何东西，我无法理解为什么。

Answer 1

我只需要添加这两行：

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

Answer 2

试试这个

$ch = curl_init(); 
curl_setopt($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))                                                                       
);
