我完全忘记了插件slug是否是获取url的可靠方法，这可能在大多数情况下都是因为插件的命名方式。

您可以在wordpress上查询api。org获取插件xml文件，该文件还包含下载链接。

例如：

$plugin_slug = \'akismet\'; 
$return_plugin_info = "http://api.wordpress.org/plugins/info/1.0/$plugin_slug.xml"

我想我迟到了，但根据新的指导方针，我发现这是最好的解决方案

   // Set the arguments. For brevity of code, I will set only a few fields.
    $args = array(
        \'slug\' => \'akismet\', // or any plugin slug
        \'fields\' => array(
            \'version\' => true
        )
    );

    // Make request and extract plug-in object. Action is query_plugins
    $response = wp_remote_post(
        \'http://api.wordpress.org/plugins/info/1.0/\',
        array(
            \'body\' => array(
                \'action\' => \'plugin_information\',
                \'request\' => serialize((object)$args)
            )
        )
    );
    //
    if ( !is_wp_error($response) ) {
        $returned_object = unserialize(wp_remote_retrieve_body($response));   

        if ($returned_object) {
            $downloaded = $returned_object->downloaded;
            print_r($downloaded);
        }
        else {
            // Response body does not contain an object/array
            echo "An error has occurred.";
        }
    }
    else {
        // Error object returned
        echo "An error has occurred";
    }
