SendGrid\Content->__construct Error

[gusbemacbe]

Issue Summary

I have copied the simple sample of an example and I have replaced text/plain for text/html. But it gave an error of SendGrid\Content->__construct. Remember I am not using Composer. I have already echoed and exported the SendGrid API key to .env.

Steps to Reproduce

1. I have copied the example from this README.md and replaced something:

<?php

require("sendgrid-php/sendgrid-php.php");

header("Access-Control-Allow-Origin: *");

$from = new SendGrid\Email("Atlética UNISAL", "contato@atleticaunisal.com.br");
$subject = "Sending with SendGrid is Fun";
$to = new SendGrid\Email("Atlética UNISAL", "contato@atleticaunisal.com.br");
$content = new SendGrid\Content("text/html", "and easy to do anywhere, even with PHP");
$mail = new SendGrid\Mail($from, $subject, $to, $content);
$apiKey = getenv('myapikey');
$sg = new \SendGrid($apiKey);
$response = $sg->client->mail()->send()->post($mail);

echo $response->statusCode();
print_r($response->headers());
echo $response->body();

2. Here is the error:

Hello @gusbemacbe,

I believe this is the solution. Please try it out and let me know how it goes. Thanks!

He used Composer and I do not. I do not want to use Composer and copy the whole folder vendor to a simple website. If you say I have to use Composer, if I copy only the folder shark/simple_html_dom to the website folder, will it work?

[gusbemacbe]

What a waste of time! The package simple_html_dom is dead and the user shark is dead too.

[thinkingserious]

I don't think you need Composer, just this:

Looks like you need to enable mbstring. See here for more detail.

[gusbemacbe]

As I have said, this package simple_html_dom is dead and doesn't exist, and I do not use Heroku.

[thinkingserious]

In Ubuntu, I think this is what you need. Please take a look and let me know how it works out. Thanks!

I installed it, but it gave another error:

401Array ( [0] => HTTP/1.1 401 Unauthorized [1] => Server: nginx [2] => Date: Sat, 24 Mar 2018 13:39:08 GMT [3] => Content-Type: application/json [4] => Content-Length: 88 [5] => Connection: keep-alive [6] => Access-Control-Allow-Origin: https://sendgrid.api-docs.io [7] => Access-Control-Allow-Methods: POST [8] => Access-Control-Allow-Headers: Authorization, Content-Type, On-behalf-of, x-sg-elas-acl [9] => Access-Control-Max-Age: 600 [10] => X-No-CORS-Reason: https://sendgrid.com/docs/Classroom/Basics/API/cors.html [11] => [12] => ) {"errors":[{"message":"Permission denied, wrong credentials","field":null,"help":null}]}

Hello @gusbemacbe,

A 401 error relates to authentication. Please verify that your API Key is being set correctly.

Thanks!

I copied the correct API key and sourced the env files. But it is still invalid.

[gusbemacbe]

I am confused.

Do I keep $apiKey = getenv('SENDGRID_API_KEY'); or replace for $apiKey = getenv('SG.ob4w0...'); or $apiKey = getenv('ob4w0...);

[gusbemacbe]

I found the solution from the tutorial, I had to replace $apiKey = getenv('SG.ob4w0...'); for $apiKey = 'SG.ob4w0...'; and it worked.

Hello @gusbemacbe,

While your solution works, we do not advise placing your API Key in your source code. Instead we recommend you store your API Key in an environment variable like so.

Thanks!
