如何使用节点js将Base64转换为HTML

Question

这里，我尝试使用猛犸npm将base64转换成html，但是它抛出了一个错误：-抛出了新的错误(“无法找到中心目录的末尾:这是一个zip文件吗？”+)

错误:找不到中央目录的末尾:这是一个zip文件吗？如果是的话，见(/Users/Desktop/mommoth/node_modules/jszip/lib/zipEntries.js:149:23) at ZipEntries.readEndOfCentral zip.html at ZipEntries.load ZipEntries at new ZipEntries (/Users/Desktop/mommoth/node_modules/jszip/lib/zipEntries.js:21:14) at JSZip.module.exports as load at new JSZip (/User/Desktop/mommoth/node_node/jszip)/lib/index.js:39:14)在(/Users/Desktop/mommoth/node_modules/mammoth/lib/zipfile.js:10:19) at Object.openZip (/Users/Desktop/mommoth/node_modules/mammoth/lib/unzip.js:16:41) at convert (/Users/Desktop/mommoth/node_modules/mammoth/lib/index.js:34:18) at Object.convertToHtml (/Users/Desktop/mommoth/node_modules/mammoth/lib( /index.js:22:12) at /Users/Desktop/mommoth/server.js:49:10 at FSReqWrap.readFileAfterClose as oncomplete

let base64Path = base64String.split(';base64,').pop();

let buff = new Buffer(base64Path, 'Base64');

console.log(buff);

mammoth.convertToHtml({ buffer :  buff })                
 .then(function(error,result){

    if(error){console.error(error)}

   else{

       console.log('convert');              
       console.log(result);
   }

  })

.done();

});

您的节点版本是什么？

new Buffer(base64Path, 'base64');

此方法适用于Node.js v5.11.1及以下版本，如果您的Node.js版本为v6.0.0或更高版本，则应以这种方式进行转换

let buff = Buffer.from(base64Path, 'base64');
