Question

我在服务器端生成Pre-Signed URL并在客户端上传file。

出于某种原因，我收到来自403 forbidden SignatureDoesNotMatch的{{1}}错误，但我看不出错误在哪里。

使用AWS请求postman，这是我收到的url：

下面我粘贴我的代码：

AngularJS

https://s3-us-west-2.amazonaws.com/my_bucket/uploads/%20VID_20160916_061949.mp4?AWSAccessKeyId=AKIAJV3UP7LBEKPYMLGA&Expires=1474005709&Signature=7KYWah4K%2FEkpdYQR%2FqYDrvCDPgQ%3D

的NodeJS

// My videoData comes as a variable
$http.post(CONFIG.API_URL + '/endpoint1', { filename: videoData[0].name })
  .success(function (resp) {
  // Perform The Push To S3
    $http.put(resp, videoData[0], { headers: {'Content-Type': videoData[0].type} })
      .success(function (resp) {
        //Finally, We're done
        callback(null, 'Upload Done!');
      })
      .error(function (resp) {
        callback("An Error Occurred Attaching Your File");
      });
  })
  .error(function (resp) {
    callback("An Error Occurred Attaching Your File");
});

getSignedUrl: function (filename, callback) {
  if (filename) {
    AWS.config.update({
      accessKeyId: 'my_access_key',
      secretAccessKey: 'my_secret_key',
      region: 'us-west-2' // I've checked the bucket is correct
    });

    var s3 = new AWS.S3();

    s3.getSignedUrl('putObject', {Bucket: 'my_bucket', Key: 'uploads/' + filename}, function (err, url) {
      if (err) {
        callback(err);
      } else {
        callback(url);
      }
    });
  } else {
    callback('Error');
  }
}

            "Resource": "arn:aws:s3:::my_bucket/uploads"
        }
    ]
}

有人能帮助我吗？

感谢您的建议！
