使用aws-sdk通过浏览器将大文件上传到aws s3时出现问题 [英] issue in uploading large files to aws s3 through browser using aws-sdk

问题描述

借助此博客 http://www.cheynewallace.com/uploading-to-s3-with-angularjs/我确实设法将较小尺寸(<30MB)的文件上传到s3存储桶.但是在上传更大的文件(大于30MB)时，我遇到了一些问题.

With the help of this blog http://www.cheynewallace.com/uploading-to-s3-with-angularjs/ I did manage to upload the files of smaller size (<30MB) to the s3 bucket. But while uploading a bit larger file (above 30MB) I am facing some issue.

error:Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at 'https://s3.amazonaws.com/**' (Reason: CORS request failed).

我在文件上传过程中遇到此错误，即，它最初开始上传，但是稍后(例如，在15％或18％上传之后)，它会触发CORS错误，并且文件上传又从0％开始

I am getting this error in the middle of file uploading i.e,initially it starts uploading ,but later (say after 15% or 18% uploaded) it is firing the CORS error and the uploading of file again starts from 0%

我是AWS S3的新手.如果我有任何疑问，请纠正我.

I am very new to AWS S3. Please correct me if I am asking anything wrong.
