ossClient.uploadFile和ossClient.downloadFile要领不撑持进度条成果.

按照官方文档 https://help.aliyun.com/document_detail/84796.html?spm=a2c4g.11186623.6.791.40554d83cDiWSN

及代码示例制作插手进度条成果 https://github.com/aliyun/aliyun-oss-java-sdk/blob/master/src/samples/GetProgressSample.java?spm=a2c4g.11186623.2.7.39811bd4Zk16e3&file=GetProgressSample.java

流式上传不撑持百分比 而new File是撑持的

流式上传:

Start to upload...... 8192 bytes have been written at this time, upload ratio: unknown(8192/...) 8192 bytes have been written at this time, upload ratio: unknown(16384/...) 8192 bytes have been written at this time, upload ratio: unknown(24576/...) 8192 bytes have been written at this time, upload ratio: unknown(32768/...) 8192 bytes have been written at this time, upload ratio: unknown(40960/...) 8192 bytes have been written at this time, upload ratio: unknown(49152/...) 8192 bytes have been written at this time, upload ratio: unknown(57344/...) 1967 bytes have been written at this time, upload ratio: unknown(59311/...) Succeed to upload, 59311 bytes have been transferred in total

而new File(localFilePath);是可以看到百分比的,从开始也获取了文件的整个巨细.

Start to upload...... 3546429 bytes in total will be uploaded to OSS 8192 bytes have been written at this time, upload progress: 0%(8192/3546429) 8192 bytes have been written at this time, upload progress: 0%(16384/3546429) 8192 bytes have been written at this time, upload progress: 0%(24576/3546429) 8192 bytes have been written at this time, upload progress: 0%(32768/3546429) 8192 bytes have been written at this time, upload progress: 1%(40960/3546429) 8192 bytes have been written at this time, upload progress: 1%(49152/3546429) 8192 bytes have been written at this time, upload progress: 1%(57344/3546429) .... .... 7485 bytes have been written at this time, upload progress: 100%(3546429/3546429) Succeed to upload, 3546429 bytes have been transferred in total

整个上传下载速度都还挺快的

试了下300MB文件每次2M/s
