使用Sendgrid api發送電子郵件

Question

我正在使用發送網格向服務器webmail發送電子郵件。以下是我的代碼。我按照教程編寫了這段代碼。但我得到的錯誤：

Warning: rawurlencode() expects parameter 1 to be string, object given in /home/cwtestco/public_html/demo/active-fit-club/sendgrid-php/vendor/guzzle/guzzle/src/Guzzle/Http/QueryString.php on line 237 

Warning: Cannot modify header information - headers already sent by (output started at /home/cwtestco/public_html/demo/active-fit-club/sendgrid-php/vendor/guzzle/guzzle/src/Guzzle/Http/QueryString.php:237) in /home/cwtestco/public_html/demo/active-fit-club/index.php on line 53 

代碼：使用下面的代碼和它的工作

if($res != false){ 
    require_once ($_SERVER['DOCUMENT_ROOT'].'/demo/active-fit-club/sendgrid-php/vendor/autoload.php'); 
    require_once ($_SERVER['DOCUMENT_ROOT'].'/demo/active-fit-club/sendgrid-php/lib/SendGrid.php'); 
    require_once ($_SERVER['DOCUMENT_ROOT'].'/demo/active-fit-club/sendgrid-php/lib/SendGrid/Exception.php'); 

    $message = "Name : $name <br> Email : $email <br> Mobile : $mobile"; 
    $sendgrid = new SendGrid('myapikey'); 
    $email = new SendGrid\Email(); 
    $email 
     ->addTo("info@abc.co.uk") 
     ->setFrom($email) 
     ->setSubject("Contact mail") 
     ->setHtml($message); 

    try { 
     $sendgrid->send($email); 
     $_SESSION['success'] = true; 
     header("location:url"); 
     exit; 
    } catch(\SendGrid\Exception $e) { 
     // echo $e->getCode(); 
     // foreach($e->getErrors() as $er) { 
     //  echo $er; 
     // } 

     header("location:url"); 
     exit; 
    } 
} 

Answer 1

IM。

$url = 'https://api.sendgrid.com/'; 
$apiKey = 'SENDGRID_API_KEY'; 

//api library from sendgrid 
require_once "sendgrid/sendgrid-php.php"; 

$sendgrid = new SendGrid($apiKey); 
$email = new SendGrid\Email(); 

$email 
    ->addTo("to@example.com") 
    ->setFromName("Fromname") 
    ->setFrom("from@example.com") 
    ->setSubject("your subject goes here") 
    ->setText('') 
    ->setHtml("your email html content goes here"); 

if($sendgrid->send($email)) 
    echo "Mail sent"; 
else 
    echo "Failed";

Answer 2

得到庫文件嘗試移動設置會話變量之前設置頁眉和設置$ _SESSION [「成功」]是「真」，而不是真實的：

try { 
     $sendgrid->send($email); 
     header("location:url");    
     $_SESSION['success'] = 'true'; 
     exit; 
    }
