使用JavaScript库解析XLSX的标头签名无效

我尝试使用这些js库和代码段创建一个excel解析器:How to parse Excel file in Javascript/HTML5

它使用以下2个js库:

https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.8.0/xlsx.js

https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.8.0/jszip.js

但是当我尝试上传任何xlsx文件时,我收到无效的标头错误: 我使用的是Mac和谷歌浏览器,并确认这些文件是真正的xlsx文件(创建新文件只是为了测试)。

xlsx.js:1660 Uncaught Header Signature: Expected d0cf11e0a1b11ae1 saw       504b030414000600CheckField 
@ xlsx.js:1660check_get_mver 
@ xlsx.js:986parse 
@ xlsx.js:898readSync 
@ xlsx.js:1212reader.onload 
@ uploadfile.js:140

有没有办法解决这个问题,或者我做错了什么?我刚刚开始使用javascript /做前端的东西。我是一名java开发人员,这种语言让我大吃一惊。

我使用的代码是:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Parse Excel</title>
</head>
<body>
Hello World!
<div id="content">
    <input type="file" id="input" />
</div>
</body>
</html>
<script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.8.0/xlsx.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/xlsx/0.8.0/jszip.js"></script>

<script>
    var filebutton = document.getElementById("input");
    filebutton.addEventListener("change", filePicked, false);


     function filePicked(oEvent) {

    // Get The File From The Input
    var oFile = oEvent.target.files[0];
    var sFilename = oFile.name;
    // Create A File Reader HTML5
    var reader = new FileReader();

    // Ready The Event For When A File Gets Selected
    reader.onload = function(e) {
        var data = e.target.result;
        var cfb = XLSX.CFB.read(data, {type: 'binary'});
        var wb = XLSX.parse_xlscfb(cfb);
        // Loop Over Each Sheet
        wb.SheetNames.forEach(function(sheetName) {
            // Obtain The Current Row As CSV
            var sCSV = XLSX.utils.make_csv(wb.Sheets[sheetName]);
            var oJS = XLSX.utils.sheet_to_row_object_array(wb.Sheets[sheetName]);

            $("#my_file_output").html(sCSV);
            console.log(oJS)
        });
    };

    // Tell JS To Start Reading The File.. You could delay this if desired
    reader.readAsBinaryString(oFile);
}

好吧,我通过巨大的反复试验和大量的浪费时间来了解它。我列出的导入顺序在jszip.js之前称为xlsx.js,但jszip.js需要在上面。
