$adminUrl='http://localhost/magento/index.php/rest/V1/integration/admin/token';

$data = array("username" => "myname", "password" => "mypassword");                                                                    
$data_string = json_encode($data);                       
$ch = curl_init($adminUrl); 
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");                                                                     
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);                                                                      
curl_setopt($ch, CURLOPT_HTTPHEADER, array(                                                                          
    'Content-Type=> application/json',                                                                                
    'Content-Length=> ' . strlen($data_string))                                                                       
);       
$token = curl_exec($ch);
print_r($token);

我尝试了上面的代码，但无法获取令牌，而是返回错误消息：

({"message":"服务器无法理解Content-Type HTTP头媒体类型application/x-www-form-urlencoded"},

我该如何解决这个错误？

你应该试试这个：

curl -X POST "https://magento.host/index.php/rest/V1/integration/customer/token" \
     -H "Content-Type:application/json" \
     -d '{"username":"user_example", "password":"123123q"}'

以下代码对我有用。

//Magento admin user data
$userData = array("username" => "adminuser", "password" => "adminpassword");
$ch = curl_init("http://yourdomain.com/rest/V1/integration/admin/token");
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($userData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Content-Length: " . strlen(json_encode($userData))));

$token = curl_exec($ch);

解释您的代码并提供更多细节。会有帮助的。
欢迎来到 Stack Overflow！尽管此代码可能有助于解决问题，但它并没有解释 why 和/或如何回答问题。提供这种额外的背景将显着提高其长期教育价值。请edit您的回答添加解释，包括适用的限制和假设。

【解决方案4】：

请更改您的 $adminUrl

来自：

http://localhost/magento/index.php/rest/V1/integration/admin/token

到：

http://localhost/rest/V1/integration/admin/token

这样就好了。

您可以使用它来获取管理员令牌。

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://127.0.0.1/www.yourstoreurl.com/rest/V1/integration/admin/token",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\r\n  \"username\": \"admin\",\r\n  \"password\": \"pwd@123\"\r\n}",
  CURLOPT_HTTPHEADER => array(
    "cache-control: no-cache",
    "content-type: application/json",
    "postman-token: e3deae08-0436-af2d-0449-450720bb7086"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
