如何在节点js中使用aws

    var xls = json2xls(data);
    var bufferdata = new Buffer(xls).toString('base64');
    console.log("inside upload s3 function........", data);
    //var buf = new Buffer(data, 'base64');
    var uploaddata = {
        Key: "exception.xls",
        Body: bufferdata,
        ContentEncoding: 'base64',
        ContentType: 'application/vnd.ms-excel'
    };

我能够通过s3保存和检索文件。但是出现格式不匹配的问题。请帮助我解决该问题。

尝试一下，为我工作。

const xls = json2xls(data);

const buffer = Buffer.from(xls, 'binary');

console.log("inside upload s3 function........", data);
var uploaddata = {
    Key: "exception.xls",
    Body: buffer,
    ContentType: 'application/vnd.ms-excel'
};
