Sendgrid 错误 400 错误请求

Question

我在尝试通过 SendGrid 发送电子邮件时收到此错误消息：

400 { "errors": [ { "message": "Bad Request", "field": null, "help": null } ] } array(14) { [0]=> string(25) "HTTP/1.1 400 Bad Request " [1]=> string(14) "Server: nginx " [2]=> string(36) "Date: Sat, 11 Mar 2017 19:20:44 GMT " [3]=> string(31) "Content-Type: application/json " [4]=> string(19) "Content-Length: 63 " [5]=> string(23) "Connection: keep-alive " [6]=> string(22) "X-Frame-Options: DENY " [7]=> string(58) "Access-Control-Allow-Origin: https://sendgrid.api-docs.io " [8]=> string(35) "Access-Control-Allow-Methods: POST " [9]=> string(87) "Access-Control-Allow-Headers: Authorization, Content-Type, On-behalf-of, x-sg-elas-acl " [10]=> string(28) "Access-Control-Max-Age: 600 " [11]=> string(75) "X-No-CORS-Reason: https://sendgrid.com/docs/Classroom/Basics/API/cors.html " [12]=> string(1) " " [13]=> string(0) "" }

这是我的代码：

<?php

// If you are using Composer
require 'vendor/autoload.php';

use SendGrid\Mail;

$apiKey = 'mykey';
$sg = new \SendGrid($apiKey);
$email = new SendGrid\Email("Me", "mail@gmail.com");

$mail = new SendGrid\Mail();
$mail->setFrom($email);
$mail->setSubject("Attachment Test");
$p = new \SendGrid\Personalization();
$p->addTo($email);
$c = new \SendGrid\Content("text/plain", "Hi");
$mail->addPersonalization($p);
$mail->addContent($c);

$att1 = new \SendGrid\Attachment();
$att1->setContent( file_get_contents("favicon.ico") );
$att1->setType("text/plain");
$att1->setFilename("1.txt");
$att1->setDisposition("attachment");
$mail->addAttachment( $att1 );

$response = $sg->client->mail()->send()->post($mail);

echo $response->statusCode() . "\n";
echo json_encode( json_decode($response->body()), JSON_PRETTY_PRINT) . "\n";
var_dump($response->headers());
?>

不确定是否与附件有关。我设法使用不同的代码发送了一封电子邮件，但我正在尝试为其添加附件，所以这是新代码。我知道的不多 php 所以我不太明白这个错误是什么意思。

您收到的错误是由附件引起的。

文件内容必须经过 base64 编码。否则它将导致 JSON 格式错误，因为您在请求正文中引入了随机字节。

您可以看到，在 sendgrid-php 的邮件助手的完整示例中，base64 字符串被设置为附件的内容。 https://github.com/sendgrid/sendgrid-php/blob/master/examples/helpers/mail/example.php#L83

正如您在 Attachment class 中看到的那样，内容只是简单地设置，当 class 是时，内容将在 JSON 对象中序列化为字符串序列化： https://github.com/sendgrid/sendgrid-php/blob/master/lib/helpers/mail/Mail.php#L670

你只需要使用这个功能：http://php.net/manual/en/function.base64-encode.php

要更改线路：

$att1->setContent( file_get_contents("favicon.ico") );

收件人：

$att1->setContent( base64_encode( file_get_contents("favicon.ico") ) );

v3 邮件发送文档在此处：https://sendgrid.com/docs/API_Reference/Web_API_v3/Mail/index.html

如果向下滚动到 "attachments" 对象并展开 "content" 字段，它会显示它的要求，maily：The Base64 encoded content of the attachment.
