TypeError:使用knox上传时在非对象上调用Object.keys

Question

我正在使用knox(https://github.com/LearnBoost/knox)将文件上传到Amazon S3.我刚刚将我的节点应用程序移动到Amazon EC2,并在使用knox上传时出现以下错误.我似乎安装了所有库.nodejitsu上的代码相同.我对node/JS很新,所以我不确定这意味着什么.

/home/ec2-user/foo/node_modules/knox/lib/auth.js:208
Object.keys(url.query).forEach(function (key) {
^
TypeError: Object.keys called on non-object

也许，你和我一样，将“mimetype”字符串作为 client.putFile() 函数中的第三个参数传递......

您必须传递一个指定内容类型标头的对象：

client.putFile(localPath, s3Path, {'Content-Type': mimetype}  ,function(err, result) {});

或者只是忽略第三个参数（就像我一样）：

client.putFile(localPath, s3Path, function(err, result) {});
