在C＃中将对象上传到Google云存储桶 [英] Uploading objects to google cloud storage buckets in c#

问题描述

有人可以提供一个示例，说明如何使用Google.Apis.Storage.v1将文件上传到c＃中的Google云存储吗？

Can someone please provide an example of how to use Google.Apis.Storage.v1 for uploading files to google cloud storage in c#?

推荐答案

我发现此基本操作并不像您期望的那样简单。 Google缺乏有关其Storage API的文档，缺乏有关以C＃（或任何其他.NET语言）使用它的信息。搜索 如何在C＃中将文件上传到Google云存储并不能完全为我提供帮助，因此这是我的工作解决方案，并带有一些注释：

I found that this basic operation is not as straight forward as you might expect. Google's documentation about it's Storage API is lacking in information about using it in C# (or any other .NET language). Searching for 'how to upload file to google cloud storage in c#' didn't exactly help me, so here is my working solution with some comments:

准备工作：

Preparation:

1. 您需要在Google Developers Console中创建OAuth2帐户-到项目/ API和

1. You need to create OAuth2 account in your Google Developers Console - go to Project/APIs & auth/Credentials.

复制客户端ID&客户密码的秘密。您还将需要您的项目名称。

Copy Client ID & Client Secret to your code. You will also need your Project name.

代码（假定您已经添加了Google.Apis .NuGet.Storage.v1）：

首先，您需要授权请求：

First, you need to authorize your requests:

var clientSecrets = new ClientSecrets();
clientSecrets.ClientId = clientId;
clientSecrets.ClientSecret = clientSecret;
//there are different scopes, which you can find here https://cloud.google.com/storage/docs/authentication
var scopes = new[] {@"https://www.googleapis.com/auth/devstorage.full_control"};

var cts = new CancellationTokenSource();
var userCredential = await GoogleWebAuthorizationBroker.AuthorizeAsync(clientSecrets,scopes, "yourGoogle@email", cts.Token);

有时您可能还想通过以下方式刷新授权令牌：

Sometimes you might also want to refresh authorization token via:

await userCredential.RefreshTokenAsync(cts.Token);

您还需要创建存储服务：

You also need to create Storage Service:

var service = new Google.Apis.Storage.v1.StorageService();

现在您可以向Google Storage API发出请求了。
让我们从创建新存储桶开始：

Now you can make requests to Google Storage API. Let's start with creating a new bucket:

var newBucket = new Google.Apis.Storage.v1.Data.Bucket()
{
    Name = "your-bucket-name-1"
};

var newBucketQuery = service.Buckets.Insert(newBucket, projectName);
newBucketQuery.OauthToken = userCredential.Result.Token.AccessToken;
//you probably want to wrap this into try..catch block
newBucketQuery.Execute();

就可以了。现在，您可以发送请求以获取所有存储桶的列表：

And it's done. Now, you can send a request to get list of all of your buckets:

var bucketsQuery = service.Buckets.List(projectName);
bucketsQuery.OauthToken = userCredential.Result.Token.AccessToken;
var buckets = bucketsQuery.Execute();

最后一部分是上传新文件：

//enter bucket name to which you want to upload file
var bucketToUpload = buckets.Items.FirstOrDefault().Name;
var newObject = new Object()
{
    Bucket = bucketToUpload,
    Name = "some-file-"+new Random().Next(1,666)
};

FileStream fileStream = null;
try
{
    var dir = Directory.GetCurrentDirectory();
    var path = Path.Combine(dir, "test.png");
    fileStream = new FileStream(path, FileMode.Open);
    var uploadRequest = new Google.Apis.Storage.v1.ObjectsResource.InsertMediaUpload(service, newObject,
    bucketToUpload,fileStream,"image/png");
    uploadRequest.OauthToken = userCredential.Result.Token.AccessToken;
    await uploadRequest.UploadAsync();
}
catch (Exception ex)
{
    Console.WriteLine(ex.Message);
}
finally
{
    if (fileStream != null)
    {
        fileStream.Dispose();
    }
}

还有！新文件将显示在您选定的存储桶中的Google Developers Console中。

And bam! New file will be visible in you Google Developers Console inside of selected bucket.
