如何使用PHP cURL发布JSON数据？ [英] How to POST JSON Data With PHP cURL?

问题描述

这是我的代码，

  $ url ='url_to_post'; 
 $ data = array（first_name=>名字，last_name=>姓氏，email=>[e-mail]，地址=> ; array（address1=>some address，city=>city，country=>CA，first_name=>Mother，last_name=> Lastnameson，phone=>555-1212，province=>ON，zip=>123 ABC 
 $ data_string = json_encode（$ data）; 
 $ ch = curl_init（$ url）; 
 curl_setopt（$ ch，CURLOPT_CUSTOMREQUEST，POST）; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，array（customer=> $ data_string））; 
 curl_setopt（$ ch，CURLOPT_HEADER，true）; 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，
 array（'Content-Type：application / json'，
'Content-Length：'。strlen（$ data_string））
）; 
 
 $ result = curl_exec（$ ch）; 
 curl_close（$ ch）; 
  

在其他页面，我正在检索帖子数据。

  print_r（$ _POST）; 
  

输出

  HTTP / 1.1 200 OK 
 Date：Mon，18 Jun 2012 07:58:11 GMT 
服务器：Apache 
 X-Powered-By：PHP / 5.3.6 
 Vary：Accept-Encoding 
 Connection：close 
 Content-Type：text / html 
 
 Array（）
  pre> 
 
 
所以，我没有得到正确的数据，即使在我自己的服务器，它是空数组。我想使用json实现REST，如 http://docs.shopify.com/api/customer#创建 
解决方案
您错误地提交了json  - 但即使它是正确的，使用 print_r（$ _ POST）（阅读原因） 。您可以在第二页上使用  file_get_contents（php：// input）来命名传入的请求，它将包含POSTed json 。要以更可读的格式查看接收的数据，请尝试以下操作：
  echo'< pre>'。print_r（json_decode file_get_contents（php：// input）），1）。'< / pre>'; 
  
在您的代码中，您指示 Content-Type：application / json ，但是你不是json编码所有的POST数据 - 只有customerPOST字段的值。而是这样做：
  $ ch = curl_init（$ url）; 
＃设置请求通过POST发送json。 
 $ payload = json_encode（array（customer=> $ data））; 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，$ payload）; 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，array（'Content-Type：application / json'））; 
＃返回响应而不是打印。 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; 
＃发送请求。 
 $ result = curl_exec（$ ch）; 
 curl_close（$ ch）; 
＃打印响应。 
 echo< pre> $ result< / pre>; 
  
  Sidenote：您可能会受益于使用第三方库，而不是直接与Shopify API直接交流。 
 
Here is my code,
    $url = 'url_to_post';
    $data = array("first_name" => "First name","last_name" => "last name","email"=>"[e-mail]","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
    $data_string = json_encode($data);
    $ch=curl_init($url);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, array("customer"=>$data_string));
    curl_setopt($ch, CURLOPT_HEADER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER,
               array('Content-Type:application/json',
                      'Content-Length: ' . strlen($data_string))
               );

    $result = curl_exec($ch);
    curl_close($ch);
And at other page, I am retrieving post data. 
    print_r ($_POST);
Output is 
HTTP/1.1 200 OK
Date: Mon, 18 Jun 2012 07:58:11 GMT
Server: Apache
X-Powered-By: PHP/5.3.6
Vary: Accept-Encoding
Connection: close
Content-Type: text/html

Array ( ) 
So, I am not getting proper data even at my own server, it's empty array. I want to implement REST using json as at http://docs.shopify.com/api/customer#create
解决方案
You are POSTing the json incorrectly -- but even if it were correct, you would not be able to test using print_r($_POST) (read why here).  Instead, on your second page, you can nab the incoming request using file_get_contents("php://input"), which will contain the POSTed json.  To view the received data in a more readable format, try this: 
echo '<pre>'.print_r(json_decode(file_get_contents("php://input")),1).'</pre>';
In your code, you are indicating Content-Type:application/json, but you are not json-encoding all of the POST data -- only the value of the "customer" POST field.  Instead, do something like this:
$ch = curl_init( $url );
# Setup request to send json via POST.
$payload = json_encode( array( "customer"=> $data ) );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $payload );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
# Return response instead of printing.
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
# Send request.
$result = curl_exec($ch);
curl_close($ch);
# Print response.
echo "<pre>$result</pre>";
Sidenote: You might benefit from using a third-party library instead of interfacing with the Shopify API directly yourself.
