如何在Javascript中保存zip文件的二进制数据？ [英] How to save binary data of zip file in Javascript?

问题描述

我从AJAX响应中得到以下响应：

这是zip文件的响应。 请告诉我如何在Javascript中保存此文件名.zip。在ZIP内有PDF文件。

我的代码如下：

$.ajax({

    url: baseURLDownload + "/service/report-builder/generateReportContentPDF",
    beforeSend: function (xhr) {
        xhr.setRequestHeader("Access-Control-Allow-Origin", "*");
        xhr.responseType = 'arraybuffer'
    },
    type: "POST",
    data: JSON.stringify(parameter),
    contentType: "application/json",
    success: function(result) {
        console.log("ssss->"+result);
        var base64String = utf8_to_b64(result);
        //window.open("data:application/zip;base64,"+base64String); // It will download pdf in zip
        var zip = new JSZip();
        zip.add("PDFReport.pdf", result);
        content = zip.generate();
        location.href="data:application/zip;base64," + content;
        $.mobile.loading('hide');

    },
    error: function(xhr){
        console.log("Request Status: " + xhr.status + " Status Text: " + xhr.statusText + " " + xhr.responseText);
        $.mobile.loading('hide');
        showAlert("Error occured. Unable to download Report", "Message", "OK");

    }
});

Respose console.log("SSSS->"+result)；

推荐答案

最终我得到了问题的答案：

• https://github.com/eligrey/Blob.js/
• https://github.com/eligrey/FileSaver.js/

代码如下：

var xhr = new XMLHttpRequest();
xhr.open("POST", baseURLDownload + "/service/report/QCPReport", true);
xhr.setRequestHeader("Content-type","application/json");
xhr.setRequestHeader("Access-Control-Allow-Origin", "*");
xhr.onreadystatechange = function() {
    if (xhr.readyState == 4 && xhr.status == 200) {
        // alert("Failed to download:" + xhr.status + "---" + xhr.statusText);
        var blob = new Blob([xhr.response], {type: "octet/stream"});
        var fileName = "QCPReport.zip";
        saveAs(blob, fileName);
    }
}
xhr.responseType = "arraybuffer";
xhr.send(JSON.stringify(QCPParameter));
