PHP WOPI主机和WOPI客户端通信

我对WOPI有点困惑。我想实现一个基本的例子，只是为了测试。我制作了一个基本的WOPI主机：

<?php
require 'vendor/autoload.php';
use Pux\Mux;
use Pux\Executor;

class FilesController {

    // route: /files/:name
    public function getFileInfoAction($name) {
        $path = "office/$name";
        if (file_exists($path)) {
            $handle = fopen($path, "r");
            $size = filesize($path);
            $contents = fread($handle, $size);
            $SHA256 = base64_encode(hash('sha256', $contents, true));
            $json = array(
                'BaseFileName' => $name,
                'OwnerId' => 'admin',
                'Size' => $size,
                'SHA256' => $SHA256,
                'Version' => '222888822'
            );
            echo json_encode($json);
        } else {
            echo json_encode(array());
        }
    }

    // route: /files/:name/contents
    public function getFileAction($name) {
        $path = "office/$name";
        if (file_exists($path)) {
            $handle = fopen($path, "r");
            $contents = fread($handle, filesize($path));
            header("Content-type: application/octet-stream");
            echo $contents;
        }
    }
}


$mux = new Mux;
$mux->get('/files/:name', ['FilesController','getFileInfoAction']);
$mux->get('/files/:name/contents', ['FilesController','getFileAction']);
$path = $_SERVER['PATH_INFO'];
$args = explode("&", $path);
$route = $mux->dispatch( $args[0] );
Executor::execute($route);

您需要获取“发现XML”，然后提取要使用的“应用程序”的“编辑”URL

此URL将包含某些内容作为查询参数，您必须根据希望利用的功能删除或保留这些参数

<?php
$wopi_url= ''; // ??????
$access_token = 'xxx';
$access_token_ttl = 1000 * 60;
?>

<form id="office_form" name="office_form" target="office_frame" action='<?php $wopi_url; ?>' method="post">
    <input name="access_token" value='<?php $access_token; ?>' type="hidden" />
    <input name="access_token_ttl" value='<?php $access_token_ttl; ?>' type="hidden" />
</form>

<span id="frameholder"></span>

<script type="text/javascript">
    var frameholder = document.getElementById("frameholder");
    var office_frame = document.createElement("iframe");
    office_frame.name = "office_frame";
    office_frame.id ="office_frame";
    frameholder.appendChild(office_frame);
    document.getElementById("office_form").submit();
</script>
