I am writing code to upload files to AWS S3 and receiving this exception:
我正在编写代码以将文件上传到 AWS S3 并收到此异常：
AmazonClientException: No RegionEndpoint or ServiceURL configured
AmazonClientException：未配置 RegionEndpoint 或 ServiceURL
My code:
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:\telerikFileginabdfglil.com", bucketName);
The exception:
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()
What should I do?
我该怎么办？

The short answer to error...
错误的简短回答...
Amazon.Runtime.AmazonClientException: No RegionEndpoint or ServiceURL configured
Amazon.Runtime.AmazonClientException：未配置 RegionEndpoint 或 ServiceURL
...in my case was to specify a region when constructing the client object (for me it was AmazonSimpleEmailServiceClient).
...在我的情况下是在构造客户端对象时指定一个区域（对我来说是AmazonSimpleEmailServiceClient）。
Assuming you're using BasicAWSCredentialsthen try this:
假设你正在使用BasicAWSCredentials然后试试这个：
var credentials = new BasicAWSCredentials(accessKeyID, secretKey);
new AmazonS3Client(credentials, RegionEndpoint.USEast1);
// ^^^^^^^^^^^^^^^^^^^^^^ add this

In Asp.Net this error can be fixed by adding this line to Web.config:
在 Asp.Net 中，可以通过将此行添加到 Web.config 来修复此错误：
<add key="AWSRegion" value="us-east-1" />
Worked for me for AWSSDK.SimpleEmail v3.3
对我来说有效 AWSSDK.SimpleEmail v3.3

First of all, you shouldn't hardcode aws credentials.
首先，您不应该对 aws 凭据进行硬编码。
I had a similar error. Turned out it was due to changes in .Net Core:
我有一个类似的错误。原来这是由于 .Net Core 的变化：
One of the biggest changes in .NET Core is the removal of ConfigurationManager and the standard app.config and web.config files
https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-netcore.html
.NET Core 中最大的变化之一是删除了 ConfigurationManager 和标准的 app.config 和 web.config 文件
https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-netcore.html
For quick and dirty approach you can create credintial profile file on your machine see https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/setup-credentials.html
对于快速和肮脏的方法，您可以在您的机器上创建凭证配置文件，请参阅https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/setup-credentials.html
e.g. C:\Users\<USERNAME>\.aws\credentialson Windows
例如C:\Users\<USERNAME>\.aws\credentials在 Windows 上
[default]
aws_access_key_id = your_access_key_id
aws_secret_access_key = your_secret_access_key
then in your code you can just do something like:
然后在您的代码中，您可以执行以下操作：
var dbClient = new AmazonDynamoDBClient(new StoredProfileAWSCredentials(),
RegionEndpoint.USEast1);
A more involved way is: https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/net-dg-config-netcore.html#net-core-configuration-builder
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
appsettings.Development.json
{
"AWS": {
"Profile": "local-test-profile",
"Region": "us-west-2"
}
}
var options = Configuration.GetAWSOptions();
IAmazonS3 client = options.CreateServiceClient<IAmazonS3>();

My access key id and secret key are can be used.
Therefore I give up using TransferUtility Class and chosing another Class named PutObjectRequest to upload my files
attontion:
PutObjectRequest's Property Key,it's directory name and file name must equal to local files' directory name and file name.
codes here:
可以使用我的访问密钥 ID 和密钥。
因此我放弃使用 TransferUtility 类并选择另一个名为 PutObjectRequest 的类来上传我的文件
attontion：PutObjectRequest 的属性键，它的目录名和文件名必须等于本地文件的目录名和文件名。
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:\telerikFile7977\Baby.db";
PutObjectRequest obj = new PutObjectRequest();
var fileStream = new FileStream(localPath, FileMode.Open, FileAccess.Read);
// obj.FilePath= @"E:\telerikFile7977\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);

If you are using TransferUtility()try this:
如果你正在使用TransferUtility()试试这个：
var credentials = new BasicAWSCredentials(accessKeyID, secretKey);
var S3Client = new AmazonS3Client(credentials, RegionEndpoint.USEast1);
this._transferUtility = new TransferUtility(S3Client);
