直到最近才开始工作,我不确定发生了什么变化。我正在使用S3 SDK生成presignedUrl并使用它将文件上传到存储桶。该文件实际上传,响应返回一个200的statusCode但奇怪的是没有响应体。
我无法理解我是否错过了某种标题,或者他们是否错了。响应标头上的Content-length
让我担心。
非常感谢任何帮助!
注意:我已经模糊了这些值,如果它们有用,我可以在

我使用go
SDK对其进行了再现,以确认API本身的行为方式,而非nodejs
中的特定内容。
正如我从实验中看到的那样,这是一种正常的行为,它不会从PUT
请求返回任何内容。
OBS:我掩盖了一些敏感的价值观!

resp, err := client.Do(req2)

执行输出:
