Question

我正在尝试使用来自法兰克福或都柏林实例的s3cmd从ec2上传文件到s3：

s3cmd put -r folder  s3://bucket

但是，我得到了：

ERROR: S3 error: 400 (InvalidRequest): The authorization mechanism you have provided is not supported. Please use AWS4-HMAC-SHA256.

我看到this question建议通过执行以下操作将配置设置为V4：

signatureVersion: 'v4'

如何使用s3cmd命令执行此操作？

Answer 1

您必须使用最新版本1.6.1

只需按以下方式或您可能想要使用的任何其他方式升级s3cmd。

pip install --upgrade

Answer 2

我有同样的问题。地区是亚太地区（孟买）。其实际区域为ap-south-1。这是链接 http://docs.aws.amazon.com/general/latest/gr/rande.html 还使用cmd配置AWSCLI aws configure set default.s3.signature_version s3v4 这是链接 http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html

这里有完整的workCode

var express = require('express');
var app = express();
var http = require('http').Server(app);
var fs = require('fs');
var aws = require('aws-sdk');
var S3FS = require('s3fs');

var s3fsImpl = new S3FS('ipxstorage/products', { accessKeyId:'Use your accesskey', secretAccesskey:'use your sck', region:'ap-south-1'});
var multiparty = require('connect-multiparty');
var multipartyMiddleware = multiparty();
aws.config.update({ signatureVersion:'v4'});

app.use(express.static(__dirname + '/public'));
app.set('views', __dirname+'/public/');
app.engine('html', require('ejs').renderFile);
app.use(multipartyMiddleware);

app.post('/upload', function(req, res){
    console.log(req.files.file);
    var file = req.files.file;
    var stream = fs.createReadStream(file.path);
    return s3fsImpl.writeFile(file.originalFilename, stream).then( function(){
        console.log('File Saved...');

        res.redirect('/')
    });
});


<form action="upload" method="POST" enctype="multipart/form-data">                    
                   <div class="file-field input-field">
                       <div class="btn"><span>Browse File</span><input name="file" type="file"></div>
                       <div class="file-path-wrapper">
                           <input class="file-path validate" type="text">
                       </div>

                   </div>                    
                   <button class="btn" type="Submit">Submit</button>
               </form>

s3cmd put - 不支持您提供的授权机制。请使用AWS4-HMAC-SHA256
