如何将大的RQL结果导出到CSV文件？

Question

我目前正在使用RQL（资源查询语言），现在我想将包含约40.000行的整个表导出到CSV文件中。

我的脚本如下：

public async exportCSV() {
    let queryCSV = "?q=";
    queryCSV += this.getRQLSelect();

    this.loading = true;
    const headers = new HttpHeaders({'Accept': 'application/csv'});
    await this.http.get(this.path + queryCSV, {
        headers: headers,
        responseType: "text",
        observe: 'response'
    }).toPromise().then(res => {
        const blob = new Blob(['\ufeff' + res.body], {type: 'text/csv;charset=utf-8;'});
        const downlaodLink= document.createElement("a");
        const url = URL.createObjectURL(blob);
        const isSafariBrowser = navigator.userAgent.indexOf('Safari') !== -1 && navigator.userAgent.indexOf('Chrome') === -1;
        if (isSafariBrowser) {  //if Safari open in new window to save file with random filename.
            downlaodLink.setAttribute("target", "_blank");
        }

        downlaodLink.setAttribute("href", url);
        downlaodLink.setAttribute("download", "File.csv");
        downlaodLink.style.visibility = "hidden";
        document.body.appendChild(downloadLink);
        downlaodLink.click();
        document.body.removeChild(downlaodLink);
    });
    this.loading = false;
}

例如，如果我将查询限制设置为50行，则一切正常，但是如果我尝试导出整个结果集，则浏览器窗口将冻结。

如何在不使浏览器崩溃的情况下导出整个数据表？
