如何使用PHP cURL发布JSON数据?

标签: php json rest curl

这是我的代码,

    $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" ) );
    $data_string = json_encode($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
Server: Apache
X-Powered-By: PHP/5.3.6
Vary: Accept-Encoding
Connection: close
Content-Type: text/html

Array ( ) 

所以,即使在我自己的服务器上,我也没有获得正确的数据,它是空数组。我想在http://docs.shopify.com/api/customer#create

使用json实现REST

您正在错误地发布json - 但即使它是正确的,您也无法使用print_r($_POST)read why here)进行测试。相反,在第二页上,您可以使用 file_get_contents("php://input")来捕获传入的请求,其中包含POSTed json 。要以更易读的格式查看收到的数据,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,但您不是json编码所有POST数据 - 只是“customer”POST字段的值。相反,做这样的事情:

$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:您可能会因使用a third-party library而不是直接与Shopify API接口而受益。

替换

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

使用:

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

我不明白你对“其他页面”的意思,我希望它的页面是:'url_to_post'。如果该页面是用PHP编写的,那么上面发布的JSON将以下面的方式阅读:

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

请尝试以下代码: -

axios.post("/api/user/login", { data })
.then(res => {
  console.log("res =>", res);
  console.log("res data =>", res.data);
  console.log("res token => ", res.token);
  console.log("res data token =>", res.data.token);
});

此代码对我有用。您可以尝试...

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;
?>

您的page2.php代码

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

?>

首先

  1. 始终使用CURLOPT_CAPATH选项定义证书,

  2. 确定如何传输您发布的数据。

1个证书

默认情况下:

  • CURLOPT_SSL_VERIFYHOST == 2,其中“ 检查公用名的存在,并验证其是否与提供的主机名匹配”和

  • CURLOPT_VERIFYPEER == true,其中“ 验证对等方的证书”。

所以,您要做的就是:

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

取自工作类,其中SERVER_ROOT是应用程序引导过程中定义的常量,例如在自定义类加载器,另一个类等中。

忘记 \curl_setopt($handler, CURLOPT_SSL_VERIFYHOST, 0);\curl_setopt($handler, CURLOPT_SSL_VERIFYPEER, 0);之类的东西。

找到there问题中看到的cacert.pem this

2种开机自检模式

发布数据时实际上有两种模式:

  • 使用Content-Type标头设置为multipart/form-data

    进行数据传输
  • 数据是采用application/x-www-form-urlencoded编码的Urlencoded字符串。

在第一种情况下,您传递数组,而在第二种情况下,您传递 urlencoded字符串

multipart/form-data例如:

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

application/x-www-form-urlencoded例如:

$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

以您的命令行对其进行测试

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。

试试这样:

$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);

你忘记的关键是json_encode你的数据。但是你也可以发现使用curl_setopt_array通过传递一个数组来设置所有curl选项很方便。
