fastdfs go client implement
1 support
upload(UploadByFilename,UploadByBuffer)
download(DownloadToFile,DownloadToBuffer)
delete(DeleteFile)
2 append is not support(limited by fastdfs server)
you can implement append with delete origin && upload new again
3 UploadByFilename realized with sendfile syscall in linux,so UploadByBuffer is depracated
4 realized conn_pool,pool_size control by config file
5 details see client_test.go,good luck ^_^
