AWS：无法确定流式上载的流大小

Question

我正在尝试将图像文件从临时php文件存储路径上传到S3。文件大小约为100 kb，最大值为500 kb。

上传时我收到此错误：

Fatal error: Uncaught exception 'RequestCore_Exception' with message 'The stream size for the streaming upload cannot be determined.' in /var/www/project/releases/201303242100/application/libraries/AWS_SDK_1.6.0/lib/requestcore/requestcore.class.php:725

我认为我不需要在这里进行分段上传，因为文件不是太大。此外，上传可以从我的本地系统运行到S3，但是当我在AWS上部署PHP实例时，上传会给我错误。任何帮助将不胜感激。

感谢你

我错过了用于图像处理的gd2库。安装后，一切都像魅力！谢谢你的帮助！
