从阿里云oss拉取部署

使用场景：由于特殊原因，前端文件构建必须使用阿里云的云效流水线进行构建，但是构建后的文件，只能存储到 oss 里面或者自身的流水线中，这里以存储到 oss 里面为例。使用 go 写一个获取文件名和文件的命令。

// go 获取 oss 文件名称和文件

package main

import (
    "flag"
    "fmt"
    "github.com/aliyun/aliyun-oss-go-sdk/oss"
    "os"
    "strings"
)

func handleError(err error) {
    fmt.Println("Error:", err)
    os.Exit(-1)
}

func main() {
    accessKeyId := "xxxx"
    accessKeySecret := "xxxx"
    endpoint := flag.String("ep", "http://oss-cn-shanghai.aliyuncs.com", "aliyun OSS endpoint")
    bucketName := flag.String("bn", "", "aliyun OSS BucketName")
    objectName := flag.String("on", "", "aliyun oss objectName")
    downloadedFileName := flag.String("df", "", "downloadedFileName")
    ossPrefix := flag.String("op", "", "ossPrefix")
    action := flag.String("ac", "getFile", "download or getFile")

    client, err := oss.New(*endpoint, accessKeyId, accessKeySecret)
    flag.Parse()

    if err != nil {
        handleError(err)
    }
    bucket, err := client.Bucket(*bucketName)
    if err != nil {
        handleError(err)
    }
    if *action == "download" {
        err = bucket.GetObjectToFile(*objectName, *downloadedFileName)
        if err != nil {
            handleError(err)
        }
    }
    if *action == "getFile" {
        lsRes, err := bucket.ListObjects(oss.MaxKeys(10), oss.Prefix(*ossPrefix))
        if err != nil {
            fmt.Println("Error:", err)
            os.Exit(-1)
        }
        var test string
        for _, object := range lsRes.Objects {
            arr := strings.Split(object.Key, "/")
            test = test + arr[len(arr)-1] + "\n"
        }
        fmt.Println(test)
    }
}
