七牛云 PHP SDK服务器鉴权失败！参数解释

昨天搞了一下午，用7牛官方的SDK demo

1.上传凭证

$policy = array(
    'callbackUrl' => 'http://api.example.com/qiniu/upload/callback',
    'callbackBody' => '{"key":"$(key)","hash":"$(etag)","fsize":$(fsize),"bucket":"$(bucket)","name":"$(x:name)"}',
    'callbackBodyType' => 'application/json'
);
$upToken = $auth->uploadToken($bucket, null, $expires, $policy, true);
print($upToken . "\n");

2.回调鉴权方法

<?php
    require_once __DIR__ . '/../autoload.php';
    use Qiniu\Auth;
    $accessKey = getenv('QINIU_ACCESS_KEY');
    $secretKey = getenv('QINIU_SECRET_KEY');
    $bucket = getenv('QINIU_TEST_BUCKET');
    $auth = new Auth($accessKey, $secretKey);
    //获取回调的body信息
    $callbackBody = file_get_contents('php://input');
    //回调的contentType
    $contentType = 'application/x-www-form-urlencoded';
    //回调的签名信息，可以验证该回调是否来自七牛
    $authorization = $_SERVER['HTTP_AUTHORIZATION'];
    //七牛回调的url，具体可以参考：http://developer.qiniu.com/docs/v6/api/reference/security/put-policy.html
    $url = 'http://172.30.251.210/upload_verify_callback.php';
    $isQiniuCallback = $auth->verifyCallback($contentType, $authorization, $url, $callbackBody);
    if ($isQiniuCallback) {
        $resp = array('ret' => 'success');
    } else {
        $resp = array('ret' => 'failed');
    }
    echo json_encode($resp);

服务器已经收到信息了验证总是failed！

关键说下：

$url 参数是你的服务器回调的地址：就是上面生成token 你填的回调服务器地址就是下面的：callbackUrl

$policy = array(
    'callbackUrl' => 'http://api.example.com/qiniu/upload/callback',
    'callbackBody' => '{"key":"$(key)","hash":"$(etag)","fsize":$(fsize),"bucket":"$(bucket)","name":"$(x:name)"}',
    'callbackBodyType' => 'application/json'
);

MADE 文档里都不解释下各个参数的含义

我还以为是 “http://172.30.251.210/upload_verify_callback.php” 是固定值?
