如何通過php正確發送sendgrid電子郵件

Question

我有下面的代碼來自sendgrid用於發送帶有我的API密鑰的電子郵件但我無法讓它工作，因為它顯示

錯誤致命錯誤：未捕獲錯誤：在...中調用字符串上的成員函數send（）

我根據需要安裝了composer

看來，但是， $sendgrid->send($email)實際上並沒有返回任何內容，因此$ mail是一個空變量。 關於如何解決這個問題的任何想法。

Api鏈接源 。

    print $response->body() . "\n";

}

您正在嘗試在字符串上調用函數。

$sendgrid = 'my api goes here';

然后：

$response = $sendgrid->send($email);

我認為你的意思是：

$response = $email->send($email);
