我们正在使用 EvaporateJS 处理基于 s3 浏览器的多部分文件，使用带有临时凭证的预签名 URL。

以下将是我的配置

var amz_headers_common = {};
var amz_headers_at_initiate = {};
var amz_headers_at_upload = {};
var amz_headers_at_complete = {};

amz_headers_common['x-amz-acl'] = 'private';
amz_headers_common['x-amz-security-token'] = '<?=AWS_TOKEN;?>';
amz_headers_at_initiate['x-amz-acl'] = 'private';
amz_headers_at_initiate['x-amz-security-token'] = '<?=AWS_TOKEN;?>';

var customAuth = $("#signingMethod")[0].checked; 
Evaporate.create({
  signerUrl: customAuth ? undefined : '<?=AWS_SIGNER_URL;?>', 
  aws_key: '<?=AWS_KEY;?>' ,
  bucket: '<?=AWS_S3_BUCKET;?>',
  cloudfront: false,
  computeContentMd5: true,
  cryptoMd5Method: function (data) { return AWS.util.crypto.md5(data, 'base64'); },
  cryptoHexEncodedHash256: function (data) { return AWS.util.crypto.sha256(data, 'hex'); },
  logging: true,
  s3Acceleration: true,
  signTimeout: 10,
  s3FileCacheHoursAgo: 1,
  maxConcurrentParts:5,
  allowS3ExistenceOptimization: true,
  sendCanonicalRequestToSignerUrl: true,
  customAuthMethod: customAuth? doNotUseUnsafeJavaScriptV4Signer : undefined,
  evaporateChanged: function (file, evaporatingCount) {
     $('#totalParts').text(evaporatingCount);
     if (evaporatingCount > 0) {
        $("#pause-all, #pause-all-force, #cancel-all").show();
     } else if (evaporatingCount === 0) {
        $("#pause-all, #pause-all-force, #resume, #cancel-all").hide();
     }
  }
})
var promise = _e_.add({
 name: name,
 file: files[i],
 started: callback_methods.started,
 complete: callback_methods.complete,
 cancelled: callback_methods.cancelled,
 progress: callback_methods.progress,
 error: callback_methods.error,
 warn: callback_methods.warn,
 paused: callback_methods.paused,
 pausing: callback_methods.pausing,
 resumed: callback_methods.resumed,
 nameChanged: callback_methods.nameChanged,
 xAmzHeadersCommon: amz_headers_common,
 xAmzHeadersAtInitiate: amz_headers_at_initiate,
 xAmzHeadersAtUpload: amz_headers_at_upload,
 xAmzHeadersAtComplete: amz_headers_at_complete
},
{
 bucket: '<?=AWS_S3_BUCKET;?>',  // Shows that the bucket can be changed per
 aws_key: '<?=AWS_KEY;?>' // Shows that aws_key can be changed per
}

但我收到以下签名不匹配错误。

AWS 代码：SignatureDoesNotMatch，消息：我们计算的请求签名与您提供的签名不匹配。检查您的密钥和签名方法。状态：403

以下将是日志

请帮我解决签名不匹配的问题。

无论您在何处为存储桶实例化 S3 客户端，您都需要将签名版本设置为 v4，因为这是为您配置临时凭证的用途。像这样的东西：

var s3 = new AWS.S3({
      signatureVersion: 'v4'
});
