取代

curl_setopt($ch, CURLOPT_POSTFIELDS, array("customer"=>$data_string));

:

$data_string = json_encode(array("customer"=>$data));
//Send blindly the json-encoded string.
//The server, IMO, expects the body of the HTTP request to be in JSON
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

我不明白你说的“其他页面”是什么意思，我希望它是在:'url_to_post'的页面。如果该页面是用PHP编写的，那么你刚刚发布的JSON将以以下方式读取:

$jsonStr = file_get_contents("php://input"); //read the HTTP body.
$json = json_decode($jsonStr);

试着这样做:

$url = 'url_to_post';
// this is only part of the data you need to sen
$customer_data = array("first_name" => "First name","last_name" => "last name","email"=>"email@gmail.com","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
// As per your API, the customer data should be structured this way
$data = array("customer" => $customer_data);
// And then encoded as a json string
$data_string = json_encode($data);
$ch=curl_init($url);

curl_setopt_array($ch, array(
    CURLOPT_POST => true,
    CURLOPT_POSTFIELDS => $data_string,
    CURLOPT_HEADER => true,
    CURLOPT_HTTPHEADER => array('Content-Type:application/json', 'Content-Length: ' . strlen($data_string)))
));

$result = curl_exec($ch);
curl_close($ch);

您忘记的关键是json_encode您的数据。但是您也可能会发现，通过传递一个数组，使用curl_setopt_array一次性设置所有curl选项是很方便的。

试试这个例子。

<?php 
 $url = 'http://localhost/test/page2.php';
    $data = array("first_name" => "First name","last_name" => "last name","email"=>"email@gmail.com","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );
    $ch=curl_init($url);
    $data_string = urlencode(json_encode($data));
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
    curl_setopt($ch, CURLOPT_POSTFIELDS, array("customer"=>$data_string));


    $result = curl_exec($ch);
    curl_close($ch);

    echo $result;
?>

你的page2.php代码

<?php
$datastring = $_POST['customer'];
$data = json_decode( urldecode( $datastring));

?>

你不正确地发布了json——但即使它是正确的，你也不能使用print_r($_POST)进行测试(阅读这里的原因)。相反，在第二个页面上，您可以使用file_get_contents("php://input")获取传入请求，其中将包含post json。要以更可读的格式查看接收到的数据，请尝试以下方法:

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，但您没有对所有POST数据进行json编码——只对“customer”POST字段的值进行json编码。相反，你可以这样做:

$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>";

旁注:您可能会受益于使用第三方库，而不是直接自己与Shopify API接口。

请试试这个代码:-

$url = 'url_to_post';

$data = array("first_name" => "First name","last_name" => "last name","email"=>"email@gmail.com","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );

$data_string = json_encode(array("customer" =>$data));

$ch = curl_init($url);

curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);

curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);

curl_close($ch);

echo "$result";

$url = 'url_to_post';
$data = array("first_name" => "First name","last_name" => "last name","email"=>"email@gmail.com","addresses" => array ("address1" => "some address" ,"city" => "city","country" => "CA", "first_name" =>  "Mother","last_name" =>  "Lastnameson","phone" => "555-1212", "province" => "ON", "zip" => "123 ABC" ) );

$postdata = json_encode($data);

$ch = curl_init($url); 
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $postdata);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/json'));
$result = curl_exec($ch);
curl_close($ch);
print_r ($result);

这个代码对我有用。你可以试试……

首先,

总是用CURLOPT_CAPATH选项定义证书， 决定如何传输您的post数据。

1证书

默认情况下:

CURLOPT_SSL_VERIFYHOST == 2，它“检查公共名称的存在，并验证它是否与提供的主机名匹配”和 CURLOPT_VERIFYPEER == true“验证对端证书”。

所以，你要做的就是:

const CAINFO = SERVER_ROOT . '/registry/cacert.pem';
...
\curl_setopt($ch, CURLOPT_CAINFO, self::CAINFO);

取自一个工作类，其中SERVER_ROOT是在应用程序引导过程中定义的常量，就像在自定义类加载器或其他类中一样。

忘记类似\curl_setopt($handler, CURLOPT_SSL_VERIFYHOST, 0);或者\curl_setopt($handler, CURLOPT_SSL_VERIFYPEER, 0);

找到cacert。在这个问题中可以看到。

2 POST模式

在发布数据时，实际上有两种模式:

数据传输时，Content-Type报头设置为multipart/form-data或， 数据是一个urlencoded字符串，使用application/x-www-form-urlencoded编码。

在第一种情况下，你传递一个数组，而在第二种情况下，你传递一个urlencoded字符串。

多部分/格式例:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

应用程序/ x-www-form-urlencoded例:

$fields = array('a' => 'sth', 'b' => 'else');
$ch = \curl_init();
\curl_setopt($ch, CURLOPT_POST, 1);
\curl_setopt($ch, CURLOPT_POSTFIELDS, \http_build_query($fields));

http_build_query:

在命令行上测试它

user@group:$ php -a
php > $fields = array('a' => 'sth', 'b' => 'else');
php > echo \http_build_query($fields);
a=sth&b=else

POST请求的另一端将定义适当的连接模式。
