S3上无法使用Chunked上传文件 ｜ Unable to use Chunked to upload files on S3

我通过SDK生成一个加签的URL，然后使用Apache.HttpClient去上传数据，以Inputstream的方式，并且无法预估Content-Length。 此时会报错 <Code>NotImplemented</Code> <Message>A header you provided implies functionality that is not implemented</Message>

<Header>Transfer-Encoding</Header>

看了一些文章，是必须要指定Content-Length

但是通过InputStream的方式是无法预估Content-Length大小的，这种情况如何成功上传呢？

I generate a signed URL through the SDK, and then use Apache.HttpClient to upload data in the form of Inputstream, and the Content-Length cannot be estimated. At this time, an error will be reported <Code>NotImplemented</Code> <Message>A header you provided implies functionality that is not implemented</Message>

<Header>Transfer-Encoding</Header>

After reading some articles, it is necessary to specify Content-Length

However, the Content-Length size cannot be estimated through the InputStream method. How to upload successfully in this case?
