GoogleSheetsAPI：调用未定义函数GuzzleHttp\Psr7\stream_for（）

我目前正在开发一个WordPress插件，该插件可以从用户那里获取数据并将其附加到Google Spreadsheet，该功能在该插件上进行了一些修改之前可以正常工作，但是不再起作用，我可以似乎无法使其正常工作，无论我做什么，我都会不断收到与Sheets库相关的错误消息。

[06-Dec-2019 15:19:04 UTC] PHP Fatal error: Uncaught Error: Call to undefined function GuzzleHttp\Psr7\stream_for() in C:\laragon\www\wp\wp-content\plugins\so-application\includes\sheet\vendor\guzzlehttp\psr7\src\Request.php:54

我尝试更新Sheets客户端库，但没有任何效果，为了缩小错误的范围，我制作了一个单独的插件，重点关注该问题，以确保没有其他冲突，下面是该类的类。插件：

/*
Plugin Name: SO Plugin
*/
// If this file is called directly,abort.
if (!defined('ABSPATH')) {
exit; //Exit if accessed directly
}
define('WP_SO_PLUGIN_VERSION','1.0.0');
define('WP_SO_PLUGIN_PATH',plugin_dir_path(__FILE__));
class SO_Plugin
{
function __construct()
{
$this->load_libs();
$this->init_hooks();
}
private function init_hooks()
{
add_action('wp_ajax_nopriv_initialize',array($this,'initialize'));
add_action('wp_ajax_initialize','initialize'));
}
private function initGoogleSheetsApi()
{
putenv('GOOGLE_APPLICATION_CREDENTIALS=' . WP_SO_PLUGIN_PATH . 'includes/sheet/serviceaccount.json'); // The service account
$client = new Google_Client();
$client->useApplicationDefaultCredentials();
$client->setScopes(Google_Service_Sheets::SPREADSHEETS);
$client->setapplicationName('SO Application');
$service = new Google_Service_Sheets($client);
return $service;
}
public function initialize()
{
$service = $this->initGoogleSheetsApi();
$spreadsheetId = "xxxxx"; // <- placeholder for spreadsheet ID
$range = "A1";
$valueRange = new Google_Service_Sheets_ValueRange();
$valueRange->setvalues(["values" => ["a","b"]]);
$cOnf= ["valueInputOption" => "RAW"];
$ins = ["insertDataOption" => "INSERT_ROWS"];
$result = $service->spreadsheets_values->append($spreadsheetId,$range,$valueRange,$conf,$ins);
if ($result) {
$range = $result['updates']['updatedRange'];
echo $range;
}
exit;
}
public function load_libs()
{
require_once WP_SO_PLUGIN_PATH . 'includes/sheet/vendor/autoload.php';
}
}
new SO_Plugin();


要运行该功能，请访问此WordPress挂钩：
