如何使用putObject从Node.js将CSV文件上传到AWS S3？

Question

I tried to directly upload the file stream as a parameter, but it didn't work.

var param = {
    Bucket: 'sql-dev',
    Key: 'Report',
    Body: new Buffer(fs.createWriteStream('./temp/ALL.csv'))
};  
s3bucket.putObject(param, function(err, data){
    if(err) console.log(err);
    else console.log(data);
});

How do I use that?

You need to use a read stream, not a write stream. Also, you shouldn't be wrapping your stream inside a Buffer.

var param = {
    Bucket: 'sql-dev',
    Key: 'Report',
    Body: fs.createReadStream('./temp/ALL.csv')
};  
s3bucket.putObject(param, function(err, data){
    if(err) console.log(err);
    else console.log(data);
});
