file-server-sdk

neptune 文件服务sdk，依赖file-server-gateway 和 file-server。其中file-server-gateway 作为文件存储服务的网关层，上传文件时会负载均衡到容量最小的file-server ，同时起CDN的作用， file-server 可以横向扩容。

upload file by bytes

    client, err := ossClient.NewGrpcOssClient(context.Background(), "endpoint", "")
    if err != nil {
    	return
    }
    client.SetBucket("bucket")
    resp := client.Upload("fileName", "header", bytes.NewBuffer([]byte("")))

upload file by filePath

    client, err := ossClient.NewGrpcOssClient(context.Background(), "endpoint", "")
    if err != nil {
        fmt.Println(err)
        return
    }
    client.SetBucket("bucket")
    resp := client.UploadFromFile("fileName", "header", "filePath")

chunk upload file by bytes

    client, err := ossClient.NewGrpcOssClient(context.Background(), "endpoint", "")
    if err != nil {
        fmt.Println(err)
        return
    }
    client.SetBucket("bucket")
    resp := client.UploadForChunk(chunkSize, "fileName", "header", bytes.NewBuffer([]byte("")))

upload file by filePath

    client, err := ossClient.NewGrpcOssClient(context.Background(), "endpoint", "")
    if err != nil {
        fmt.Println(err)
        return
    }
    client.SetBucket("bucket")
    resp := client.UploadForChunkFromFile(chunkSize, "fileName", "header", "filePath")

download file

    client, err := ossClient.NewGrpcOssClient(context.Background(), "endpoint", "")
    if err != nil {
        fmt.Println(err)
        return
    }
    err := client.Download("fileName", "bucket")
    if err != nil {
        fmt.Println(err)
        return
    }

download file from chunk

    client, err := ossClient.NewGrpcOssClient(context.Background(), "endpoint", "")
    if err != nil {
        fmt.Println(err)
        return
    }
    err := client.DownloadForChunk(1024*1024, "fileName", "bucket")
    if err != nil {
        fmt.Println(err)
        return
    }
