使用Mozilla Backpack Connect API和PHP(Use the Mozilla Backpack Connect API with PHP)

 我想发布一个带有Mozilla Backpack Connect API的徽章（ 请查看！ ）。 为此，我已按照此文件，但我仍然无法签发徽章！ 
 
 当我尝试使用刷新令牌获取新的访问令牌时，我遇到了完全相同的问题。 所以我在这里发布了“获取新访问令牌”代码，因为它比发布代码更容易理解。 
 
 我想用cURL在PHP中执行此操作，而不是在Javascript中 。 
 
 这是我的代码： 
 
$data = array(
    'grant_type' => 'refresh_token',
    'refresh_token' => $refreshToken
);
$url = $apiRoot .'/token';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($data));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json'
));
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_STDERR, fopen('php://output', 'w+'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
var_dump($response);

curl_close($ch);
 
 在这里，我只是尝试获取一个新的访问令牌，如同一文档中所述 ，但不幸的是，我总是得到这样的回应： 
 
 
 
 错误请求：错误请求 
 在下一个（/var/www/openbadges/node_modules/express/node_modules/connect/lib/proto.js:125:13） 
 at /var/www/openbadges/node_modules/express/node_modules/connect/lib/middleware/bodyParser.js:54:23 
 在IncomingMessage。 （/var/www/openbadges/node_modules/express/node_modules/connect/lib/middleware/json.js:74:60） 
 在IncomingMessage.emit（events.js：92：17） 
 在_stream_readable.js：938：16 
 at process._tickCallback（node.js：419：13） 
 
 
 如果我看得更深，我已经对请求进行了详细说明，它给了我这个：

 接受： / 
 Content-Type：application / json

 所以，基本上，它回复了我一个错误400“错误请求”，没有更多的信息.​​..... 
 
 有关信息，如果我尝试使用Javascript ，它可以工作。 如果我这样做： 
 
$.ajax({
    type: 'POST',
    url: 'https://backpack.openbadges.org/api/token',
    data: {
        grant_type: 'refresh_token',
        refresh_token: theRefreshToken
    },
    headers: {
        'Content-Type': 'application/json'
    },
    success: function(data, textStatus, req) {
        console.log(textStatus);
        console.log(data);
    },
    error: function(xhr, textStatus, err) {
        console.log(textStatus);
        console.log(err);
        console.log(xhr);
        console.log($(this));
    }
});
 
 这让我很成功，但是当我使用PHP cURL时它不起作用！ 所以为什么 ？ 
 
 我的徽章是有效的（它通过验证没有问题）。 

I would like to issue a badge with the Mozilla Backpack Connect API (check this !). To do so, I have followed this document but I still cannot issue a badge !
 
I have the exact same problem when I just try to get a new access token using the refresh token. So I've posted the "get new access token" code here because it's a bit easier to understand than the issuing one.
 
I would like to do this in PHP with cURL, not in Javascript.
 
Here is my code :
 
$data = array(
    'grant_type' => 'refresh_token',
    'refresh_token' => $refreshToken
);
$url = $apiRoot .'/token';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, count($data));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type: application/json'
));
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_STDERR, fopen('php://output', 'w+'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
var_dump($response);

curl_close($ch);
 
Here I just trying to get a new access token, as mentioned in the same document, but unfortunately, I always get this response :
 
 
 
Bad Request: Bad Request
 at next (/var/www/openbadges/node_modules/express/node_modules/connect/lib/proto.js:125:13)

 at process._tickCallback (node.js:419:13) 
 
 
If I look deeper, I have verbosed the request and it gives me this :
 
 
 
> POST /api/token HTTP/1.1
 Host: backpack.openbadges.org
 Accept: /
 Content-Type: application/json
 Content-Length: 81

 < X-Powered-By: Express
 < Content-Length: 478
 < Connection: keep-alive
 <
 * Connection #0 to host backpack.openbadges.org left intact
 * Closing connection #0 
 
 
So, basically, it responses me an error 400 "Bad Request" with no more information...
 
For information, if I try to do it with Javascript, it works. If I do this :
 
$.ajax({
    type: 'POST',
    url: 'https://backpack.openbadges.org/api/token',
    data: {
        grant_type: 'refresh_token',
        refresh_token: theRefreshToken
    },
    headers: {
        'Content-Type': 'application/json'
    },
    success: function(data, textStatus, req) {
        console.log(textStatus);
        console.log(data);
    },
    error: function(xhr, textStatus, err) {
        console.log(textStatus);
        console.log(err);
        console.log(xhr);
        console.log($(this));
    }
});
 
This returns me a success, but when I use the PHP cURL it doesn't work ! So why ?
 
And my badge is valid (it passes the validation without problem).
