向易趣Post Order API获取curl请求，给出空字符串（PHP）

GET/post order/v2/casemanagement/{caseId}调用易趣post order API，给出一个空字符串。有人能弄清楚我的代码哪里出错了吗？我是否正确传递标题？尤其是授权的语法是否正确

<?php

error_reporting(E_ALL);  // Turn on all errors, warnings and notices for easier debugging

//Seller Authorization Token
$userAuthToken= 'Authorization:TOKEN abc123';

//Endpoint URL to Use
$url = "https://api.ebay.com/post-order/v2/casemanagement/xyz";

//Initializle cURL
$connection = curl_init();

//Set Endpoint URL
curl_setopt($connection,CURLOPT_URL,$url);

//Set HTTP Method
curl_setopt($connection, CURLOPT_HTTPGET, true);

//Create Array of  Required Headers
$headers = array();
$headers[] = $userAuthToken;
$headers[] = 'Content-Type:application/json';
$headers[] = 'X-EBAY-C-MARKETPLACE-ID:EBAY-DE';
//var_dump($headers);
//set the headers using the array of headers
curl_setopt($connection,CURLOPT_HTTPHEADER,$headers);

//set it to return the transfer as a string from curl_exec
curl_setopt($connection,CURLOPT_RETURNTRANSFER,1);

//stop CURL from verifying the peer's certificate
curl_setopt($connection, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($connection, CURLOPT_SSL_VERIFYHOST, 0);

//Execute the Request
$response = curl_exec($connection);

//close the connection
curl_close($connection);

var_dump($response);

添加
curl_setopt（$connection，CURLOPT_头，1）

返回标题并查看问题所在

我也不知道这是否重要，但我的headers数组看起来像：

$headers=数组(
“授权：”.“令牌$TOKEN”，
'内容类型：'.'应用程序/json'，
“X-EBAY-C-MARKETPLACE-ID:”“EBAY-US”，
“接受：”。“应用程序/json”，
);

所以你可以看到冒号后面有一个空格。
试试这段代码，它对我来说很好

<?php
         // Your ID and token
         $authToken = 'XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX';

         // The data to send to the API
         $post_data = json_encode(array("legacyOrderId"=>"110181400870-27973775001"));
         $url = 'https://api.sandbox.ebay.com/post-order/v2/cancellation/check_eligibility'; 
         //Setup cURL
         $header = array(
                        'Accept: application/json',
                        'Authorization: TOKEN '.$authToken,
                        'Content-Type: application/json',
                        'X-EBAY-C-MARKETPLACE-ID: EBAY-UK'
                         );
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        $response = curl_exec($ch);
        if(curl_errno($ch)){
            echo "ERROR:".curl_error($ch);
        }
        curl_close($ch); 
        echo json_decode($response,true);
     ?>

你找到解决问题的方法了吗？我也有同样的方法？？注意关闭CURLOPT_SSL_VERIFYPEER并修复您的PHP配置。任何运行最新Linux发行版的人都可能已经可以了，因为他们通过包管理器获得了curl库，最近的curl库附带了来自Mozilla.org的最新CA根证书包。这意味着您只需打开CURLOPT_SSL_VERIFYPEER，就不会出现任何错误。
