Question

我正在使用Amazon S3 webservice上传我的文件。

        var req = bucket.putObject(params).on('httpUploadProgress', function (progress) {
            ....some action
        }).send(function (err, data) {
            console.log(err);
            ....some action
        });

当我执行上述操作时，它会给我以下错误。

Error: No credentials to load

当我再次单击执行上述操作的同一按钮时，这次它正常工作。这是什么问题

Answer 1

我猜你的第一次请求时尚未加载凭据。如果您阅读引发此错误的getCredentials的SDK source，则会看到此评论：＆＃34;如果您想确保在请求之前加载您的凭据，则可以直接使用此方法提供存储在对象中的准确凭证数据＆＃34;。

Amazon S3在第一次上传请求时无法正常工作，但在第二次上传时工作
