Php 设置plimusapi以获取身份验证令牌

我需要设置plimus API以获取身份验证令牌，然后使用它将客户登录到plimus平台

我使用以下代码：

    $URL = "https://sandbox.plimus.com/services/2/tools/auth-token?shopperId=$shopperId&expirationInMinutes=$expiration";

// use base64 to encode the credentials
$authorization = base64_encode($username.':'.$password); 

$ch = curl_init();
// set URL
curl_setopt_array($ch, array(CURLOPT_URL => $URL));
// set headers
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Authorization: Basic $authorization", "Content-type: application/xml")); // This line is mandatory for every API call!
// set  HTTP request to GET
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET"); // This service (get token) is implement via RESTful GET, other services might use POST and PUT
// stop output of curl_exec to standard output (don't send output to screen)
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
// make HTTP call and read the response into an XML object

$xml = new SimpleXMLElement(curl_exec($ch));

// -------- PART II - Log the customer into Plimus (according to $target) --------

// construct plimus URL
$plimus = "https://sandbox.plimus.com/jsp/entrance.jsp?contractId=$contractId&target=$target&token={$xml->token}";
// redirect
header("Location: $plimus");

我得到以下错误，不知道原因：

Fatal error: Uncaught exception 'Exception' with message 'String could not be parsed as
XML' in xxx\get_token.php:40 Stack trace: #0 xxx\get_token.php(40): 
SimpleXMLElement->__construct('') #1 {main} thrown in xxx\get_token.php on line 40

谢谢

看起来这是我的代码，摘自文章的第二部分：

使用

var\u dump（curl\u exec（$ch））

查看您从服务器得到的确切响应

@user2186504那么，

var_dump（curl_exec（$ch））

的输出是什么呢？正如您已经看到的，完全相同的脚本对我来说很好：所以我猜您传递的一个参数（shopperId/construcd/etc）或您的凭据有问题。Firefox有一个很棒的插件叫做Poster，它是调试HTTP调用的好工具！
