生成动态pdf并将其存储在s3存储桶中

Question

在我的项目中，pdf是动态生成的。我想要的是直接将其存储到S3存储桶。这是我的代码。谁能帮助我。

public function pdftest(){
        $this->load->library('m_pdf');
        $this->load->library('S3');
        $name=rand(9999,999999);
        $html = $this->load->view('applicant-pdf', $data, true);

        //$this->m_pdf->pdf->WriteHTML($html);
        //$this->m_pdf->pdf->Output($pdfFilePath, "F");
        if($this->s3->putObjectFile($this->m_pdf->pdf->Output($pdfFilePath, "F"), "swirl-pdf",  "evidence-pdf/" . $name.".pdf", S3::ACL_PUBLIC_READ)){
            echo "success";
        }
    }
