如何使用PHP和Google Glass Mirror API批量插入时间线项目？

目前，在我处理的PHP代码库中，在4个调用中插入了几个时间线项和一个包封面，如下所示：

insert_timeline_item($mirror_service, $new_timeline_item_1, null, null);  
insert_timeline_item($mirror_service, $new_timeline_item_2, null, null);  
insert_timeline_item($mirror_service, $new_timeline_item_3, null, null);  
insert_timeline_item($mirror_service, $new_timeline_item_bundle_cover, null, null);  

我知道Java和Python通过一个批处理HTTP调用将这些内容发送到镜像API的方法。如何在PHP中实现这一点

现在，卡片到达玻璃上的速度相对较慢，例如，用户通常会尝试滚动，并在其他结果到达之前看到没有任何东西可以滚动。任何有助于所有结果同时到达的东西都会有很大帮助。我们已经通过只在最后一张卡上发出通知声音来尽可能地减轻压力，但这还不足以获得良好的用户体验。

插入时间线项目的批处理请求不能保证一次或以任何特定顺序到达。有关批处理操作的文档有一个脚注指出了这一点（请参阅“对批处理请求的响应”一节末尾的注释）。确保您的卡按顺序到达的唯一方法是等待插入时的每个返回响应，而不是启动最后一张卡以创建带有通知提示的捆绑包

编辑：当您通过将客户端设置为setUseBatch（true）来设置客户端时，可以使用一种方便的方法（Google_Http_Batch（））。见：

就PHP中的批处理请求而言，据我所知，目前还没有一种方便的方法。您必须构建自己的请求，通过stream\u context\u create（）设置上下文，然后通过fopen（）或file\u get\u contents（）发送它

我没有测试以下代码，但这是基本概念：

最终使用以下语法（）使setUseBatch正常工作。此修复程序返回请求（），此修复程序使私有方法公开（）。谢谢

// Our batch url endpoint
$endpoint = "/batch";

// Boundary for our multiple requests
$boundary = "===============SOMETHINGTHATDOESNOTMATCHCONTENT==\n";

//
// Build a series of timeline cards to insert
// probably spin this off into it's own method for simplicty sake
//
$timeline_items .= "--" . $boundary;
$timeline_items .= "Content-Type: application/http\n";
$timeline_items .= "Content-Transfer-Encoding: binary\n";
$timeline_items .= "POST /mirror/v1/timeline HTTP/1.1\n";
$timeline_items .= "Content-Type: application/json\n";

// You'd need the specific ouath2 bearer token for your user here
//
// Note, if you were simply sending a single batch to always one user,
// you could reasonably move this header to the outer /batch params
// as it will flow down to all child requests as per the documentation
//
// see "Format of a batch request" section at https://developers.google.com/glass/batch
//
$timeline_items .= "authorization: Bearer " . $user_bearer_token . "\n";

$timeline_items .= "accept: application/json\n";
$timeline_items .= "content-length: " . strlen($timeline_card_json) . "\n\n";
$timeline_items .= $timeline_card_json . "\n";
$timeline_items .= "--" . $boundary;

//
// Add some other timeline items into your $timeline_items batch
//

// Setup our params for our context
$params = array(
    'http' => array( 
        'method' => 'POST', 
        'header' => 'Content-Type: multipart/mixed; boundary="' . $boundary . '"',
        'accept-encoding' => 'gzip, deflate',     
        'content' => $timeline_items
    )
);

// Create context
$context = stream_context_create($params); 

// Fire off request
$batch_result = file_get_contents($endpoint, false, $context);
