mailgun 发送邮件 api PHP 在 GAE 中不起作用。未捕获的错误：找不到类“Mailgun\Mailgun”答案

【问题标题】：mailgun send mail api PHP not working in GAE. Uncaught Error: Class 'Mailgun\Mailgun' not foundmailgun 发送邮件 api PHP 在 GAE 中不起作用。未捕获的错误：找不到类“Mailgun\Mailgun”

【问题描述】：

我在 GAE 柔性环境中使用 mailgun API 发送邮件时遇到问题。我在想作曲家的错误边界无法加载'vendor/autoload.php'文件。

如果可以将 mailgun-php 文件整合为一个，我可以使用 composer.json 进行部署和忽略。请我需要帮助来解决这个问题。我不断收到此错误。尽管我有 composer.json 文件，但我仍然收到此错误。

mailgun.php

<?php 
require 'vendor/autoload.php';
use Mailgun\Mailgun;
# Instantiate the client.
$mgClient = new Mailgun('xxxxxxx','https://api.mailgun.net'); //ERROR THROWN HERE. CANT FIND CLASS
$domain = "mail.xxxx.com";
# Make the call to the client.
$result = $mgClient->sendMessage($domain, array(
'from'  => 'ME<mailgun@xxxx.com>',
'to'    => 'YOU <you@domain.com>',
'subject' => 'TEXT MAILGUN',
'html'    => '<html>SIMPLER AND EASIER</html>'

));
if ($result){

echo ("Email Sent");
}

【问题讨论】：

你给了我们mailgun存储库的composer.json，但是你的项目composer.json是什么？看来你没有包含这个 repo（错误信息很清楚）
@Pierre，我是新手。请协助

终于修复了 composer.json 文件。 tnx Pierre 提供线索。

composer.json

{
"require": {
    "Mailgun/Mailgun-php": "^1.0",
    "php-http/curl-client": "^1.0",
    "guzzlehttp/psr7": "^1.0",
    "php-http/message": "^1.0"
}

}
