Go 使用谷歌云存储认证

我有一个go应用程序在服务器上运行。应用程序需要访问才能将图像保存到谷歌云存储。从文档中可以看到如何创建PKCS12密钥

我正在使用

import(
storage "google.golang.org/api/storage/v1"
)

如何在应用程序中对golang“存储”客户端使用此密钥

问候

func ExampleJWTConfigFromJSON() {
    // Your credentials should be obtained from the Google
    // Developer Console (https://console.developers.google.com).
    // Navigate to your project, then see the "Credentials" page
    // under "APIs & Auth".
    // To create a service account client, click "Create new Client ID",
    // select "Service Account", and click "Create Client ID". A JSON
    // key file will then be downloaded to your computer.
    data, err := ioutil.ReadFile("/path/to/your-project-key.json")
    if err != nil {
        log.Fatal(err)
    }
    conf, err := google.JWTConfigFromJSON(data, "https://www.googleapis.com/auth/bigquery")
    if err != nil {
        log.Fatal(err)
    }
    // Initiate an http.Client. The following GET request will be
    // authorized and authenticated on the behalf of
    // your service account.
    client := conf.Client(oauth2.NoContext)
    client.Get("...")
}

详情如下:

希望这会有所帮助

func JWTConfigFromJSON(jsonKey []byte, scope ...string) (*jwt.Config, error)
{
    var key struct {
        Email      string `json:"client_email"`
        PrivateKey string `json:"private_key"`
    }
    if err := json.Unmarshal(jsonKey, &key); err != nil {
        return nil, err
    }
    return &jwt.Config{
        Email:      key.Email,
        PrivateKey: []byte(key.PrivateKey),
        Scopes:     scope,
        TokenURL:   JWTTokenURL,
    }, nil
}
