Question

我正在编写代码以将文件上传到AWS S3并收到此异常：

AmazonClientException：未配置RegionEndpoint或ServiceURL

我的代码：

Console.WriteLine("ready to upload");
AWSCredentials credentials;
credentials = new BasicAWSCredentials(accessKeyID.Trim(), secretKey.Trim());
AmazonS3Client s3Client = new AmazonS3Client(accessKeyID.Trim(), secretKey.Trim(), Amazon.RegionEndpoint.USEast1);
Console.WriteLine("Successful verification");
Console.WriteLine("Check if the bucket exists");
if (!CheckBucketExists(s3Client, bucketName))
{
    s3Client.PutBucket(bucketName);
    Console.WriteLine("create bucket");
}
TransferUtility utility = new TransferUtility();
Console.WriteLine("Upload  Directory......");
//exception here
utility.UploadDirectory(@"E:\telerikFile\13ginabdfglil.com", bucketName);

例外：

Amazon.Runtime.AmazonClientException: No RegionEndpoint or ServiceURL configured
  Amazon.Runtime.ClientConfig.Validate()
  Amazon.S3.AmazonS3Config.Validate()
  Amazon.Runtime.AmazonServiceClient..ctor(AWSCredentials credentials, ClientConfig config)
  Amazon.S3.AmazonS3Client..ctor()
  Amazon.S3.Transfer.TransferUtility..ctor()
  Telerik2Amazon.Program.UploadFile()

我该怎么办？

错误的简短回答......

Amazon.Runtime.AmazonClientException：未配置RegionEndpoint或ServiceURL

...在我的例子中是在构造客户端对象时指定一个区域（对我而言是AmazonSimpleEmailServiceClient）。

假设您正在使用BasicAWSCredentials，请尝试以下操作：

var credentials = new BasicAWSCredentials(accessKeyID, secretKey);

new AmazonS3Client(credentials, RegionEndpoint.USEast1);

//                              ^^^^^^^^^^^^^^^^^^^^^^  add this

在Asp.Net中，可以通过将以下行添加到Web.config中来解决此错误：

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib64/python2.7/pickle.py", line 1384, in load
    return Unpickler(file).load()
  File "/usr/lib64/python2.7/pickle.py", line 864, in load
    dispatch[key](self)
  File "/usr/lib64/python2.7/pickle.py", line 892, in load_proto
    raise ValueError, "unsupported pickle protocol: %d" % proto
ValueError: unsupported pickle protocol: 3

可以使用我的访问密钥ID和密钥因此，我放弃使用TransferUtility Class并选择另一个名为PutObjectRequest的类来上传我的文件
的 attontion ： PutObjectRequest的属性键，它的目录名和文件名必须等于本地文件'目录名和文件名。
代码在这里：

String s3Path = "987977/Baby.db"; Console.WriteLine("Ready to upload"); AWSCredentials credentials; credentials = new BasicAWSCredentials(accessKeyID.Trim(), secretKey.Trim()); AmazonS3Client s3Client = new AmazonS3Client(accessKeyID.Trim(), secretKey.Trim(), Amazon.RegionEndpoint.USEast1); Console.WriteLine("Successful verification"); Console.WriteLine("Check： if the bucket exists"); if (!CheckBucketExists(s3Client, bucketName)) { s3Client.PutBucket(bucketName); Console.WriteLine("Creat bucket"); } string localPath = @"E:\telerikFile\987977\Baby.db"; PutObjectRequest obj = new PutObjectRequest(); var fileStream = new FileStream(localPath, FileMode.Open, FileAccess.Read); // obj.FilePath= @"E:\telerikFile\987977\Baby.db"; obj.InputStream = fileStream; obj.BucketName = bucketName; obj.Key = s3Path; // obj.ContentBody = "This is sample content..."; obj.CannedACL = S3CannedACL.PublicRead; Console.WriteLine("uploading"); // default to set public right s3Client.PutObject(obj);

如果您使用的是TransferUtility()，请尝试以下操作：

var credentials = new BasicAWSCredentials(accessKeyID, secretKey);

var S3Client = new AmazonS3Client(credentials, RegionEndpoint.USEast1);

this._transferUtility = new TransferUtility(S3Client);

首先，您不应该对AWS凭证进行硬编码。

我有一个类似的错误。原来是由于.Net Core的更改所致：

.NET Core的最大变化之一是删除了ConfigurationManager以及标准的app.config和web.config文件

https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-netcore.html

对于快速而肮脏的方法，您可以在计算机上创建凭证配置文件，请参见https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/setup-credentials.html

例如Windows上的C:\Users\<USERNAME>\.aws\credentials

[default]
aws_access_key_id = your_access_key_id
aws_secret_access_key = your_secret_access_key

然后在代码中，您可以执行以下操作：

var dbClient = new AmazonDynamoDBClient(new StoredProfileAWSCredentials(), 
                     RegionEndpoint.USEast1);

一种更复杂的方法是：https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-netcore.html#net-core-configuration-builder

public Startup(IHostingEnvironment env)
{
    var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
        .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
        .AddEnvironmentVariables();
    Configuration = builder.Build();
}

appsettings.Development.json

{
  "AWS": {
    "Profile": "local-test-profile",
    "Region": "us-west-2"
  }
}


var options = Configuration.GetAWSOptions();
IAmazonS3 client = options.CreateServiceClient<IAmazonS3>();

我在为使用 S3 客户端的 Lambda 运行测试时收到此错误。我通过简单地提供具有在 ~/.aws/config 中定义的区域的默认配置文件解决了该错误：

[default]
region = us-west-1

无需更改 Lambda 代码。当然 YMMV 取决于您的情况。

未配置RegionEndpoint或ServiceURL
