Question

实际上，我想在Ext JS页面中触发自动下载生成的excel文件。有没有可以帮助您的示例源代码？在下面的我的个人源代码中查找实际上不起作用的代码（单击“导出csv”按钮时会调用此函数：

function exportCsv($criteresRecherche)
{
    $data = $this->executeRequete($sql);           

    header("Content-type: application/vnd.ms-excel");
    header("Content-disposition: attachment; filename=\"export_commandes.csv\"");


    $colToShow = array(
        "fournisseur"=>"Fournisseur",
        "lieudepart"=>"Départ",
        "datedepartprevue"=> "Date Dep Prevu",
        "confirme"=> "Emb.",
        "modepaiement"=>"Pmt.", 
        "incoterm"=>"Inc.",
        "containers"=>"Containers",
        "nocde"=>"CDE BIE N°",
        "nocde_associees"=>"CDE BIE ASSOC",
        "nocde_erp"=>"N° GNX",
        "aa"=>"Acheteur",
        "acp"=>"Acheteur CP",
        "resp_suivi"=>"Suivi par",
        "shippingmarks"=>"Shp.",
        "artwrk"=>"Art.",
        "positionetiquette"=>"Pos.",
        "relance1mois"=>"Rel",
        "echantillon"=>"Ech.",
        "certification"=>"Cer.",
        "consolidation"=>"Cns.",
        "etiquette_securite"=>"Sec.",
        "devise"=>"Dev.",
        "montant_total"=>"Total Achat", 
        "statut"=>"Statut",
        "datecreation"=>"Date de création",
        "dateintegration"=>"Date intégration"
    );
    echo $this->getHtmlToCsv($data, $colToShow); 
    exit();
}

下面是生成csv文件的函数。

function getHtmlToCsv($elements, $colToShow)
{
    $retour = "<table >"."\n";
    $retour .= "<tr class=\"titre\">"."\n";

    if ($colToShow && is_array($colToShow)) {
        foreach ($colToShow as $col => $libColonne) {
            $retour .= "<td>".strtr(
                $libColonne, get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "ISO-8859-1")
            )."</td>"."\n";
        }
    }
    $retour .= "</tr>"."\n";

    foreach ($elements as $element) {
        $retour .= "<tr>"."\n";
        $retour .= "<td>".strtr(
            $element['FOURNISSEUR'], get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "ISO-8859-1")
            )."</td>"."\n" ;

            $retour .= "<td>".strtr(
                $element['LIEUDEPART'], get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "ISO-8859-1")
                )."</td>"."\n" ;
            $retour .= "<td>".strtr(
                $element['DATEDEPARTPREVUE'], get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "ISO-8859-1")
                )."</td>"."\n" ;
            $retour .= "<td>".strtr(
                $element['CONFIRME'], get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "ISO-8859-1")
                )."</td>"."\n" ;
            $retour .= "<td>".strtr(
                $element['MODEPAIEMENT'], get_html_translation_table(HTML_ENTITIES, ENT_QUOTES, "ISO-8859-1")

    }
    $retour .= "</table>"."\n";
    $retour .= "<br>";

    // Balise qui force le type a texte pour ne subir aucun formattage excel
    $style = "<style>\n"

        . ".titre { font-size: 16px; font-weight: bold;}\n"

            . "</style>\n";

    $retour = utf8_decode($retour);
    return $retour ;
}

在Ext.js客户端中，我在“按钮”上具有此处理程序：

handler: function(){
    var url = "rest/my/endpoint/file?limit="+MY.singleton.AppConfig.exportLimit;
    window.open(url,'_blank');
}

在服务器端，我正在使用Java，但唯一真正相关的部分是您已经提供的标头：

httpHeaders.putSingle("Content-Disposition", "attachment; filename=\"" + FILENAME + "\"");

@Produces({CsvObjectMapperProvider.TEXT_CSV, CsvObjectMapperProvider.APPLICATION_EXCEL})

我建议尝试使用不同的内容类型：我的应用可以提供text/csv或application/vnd.ms-excel

此外，请确保返回的内容是有效的CSV（不允许使用<tags>，没有合适的换行符，没有“样式”），或者输出的是正确的Excel格式（对此不确定）

Excel文件下载被Ext JS阻止
