我要做的是用这段代码转换一个html文件

    $html = $this->load->view('ReporteIngresoView', $data, TRUE);
    $pdf = new Pdf('P', 'mm', 'A4', TRUE, 'UTF-8', FALSE);
    $pdf->SetTitle('Reporte ingreso');
    $pdf->SetHeaderMargin(30);
    $pdf->SetTopMargin(40);
    $pdf->setFooterMargin(20);
    $pdf->SetAutoPageBreak(TRUE);
    $pdf->SetAuthor('Pontificia Universidad CatÃ³lica del Ecuador');
    $pdf->SetDisplayMode('real', 'default');
    $pdf->AddPage();
    $pdf->writeHTML($html, TRUE, 0, TRUE, 0);
    $pdf->Output('My-File-Name.pdf', 'I');

另一方面我是这样接受的

Ext.Ajax.request
            (
                {
                    method: 'post',
                    url: '../servidor/archivo/ingreso/getreporte',
                    success: function(response){
                    Ext.getCmp('winReporteRegistro').update( response.responseText );
                       }
                    }
            );

我使用php(服务器)、html(创建页面)、extjs(接口)、ajax(请求)和TCPDF来创建pdf。

有什么想法吗?

您需要将响应转换为Blob( link )

link )

这就是我如何创建服务器端生成的pdf并将其显示在前端的方法。

添加代码段:

var blob = new Blob(response.responseText, {type: 'application/pdf'}); 
var objectURL = URL.createObjectURL(blob);

服务器:

$html = $this->load->view('ReporteCajaView', $data, TRUE);

    $pdf = new Pdf('P', 'mm', 'A4', TRUE, 'UTF-8', FALSE);
    $pdf->SetTitle('Reporte item');
    $pdf->SetHeaderMargin(30);
    $pdf->SetTopMargin(20);
    $pdf->setFooterMargin(20);
    $pdf->SetMargins(25, 20, 20, true);
    $pdf->SetAutoPageBreak(TRUE);
    $pdf->SetAuthor('Universidad CatÃ³lica');
    $pdf->SetDisplayMode('real', 'default');
    $pdf->setPrintHeader(FALSE);
    $pdf->setPrintFooter(FALSE);
    $pdf->AddPage();

    $id = uniqid();
    $pdf->writeHTML($html, TRUE, 0, TRUE, 0);
    $pathservidor = 'c:/wamp64/www/Archivo/pdf/';
    $pdf->Output($pathservidor . 'Reporte de caja' . '.pdf', 'F');

    echo 'c:/wamp64/www/Archivo/pdf/'.'Reporte de caja'.'.pdf';

客户:

Ext.Ajax.request
            (
                {
                    method: 'post',
                    url: '../servidor/archivo/item/getreporte',

                    success: function(response){
                    window.open(response.responseText);

                       }
                }
            );

谢谢
