我有以下代码:
public void ConfigureServices(IServiceCollection services) { // AWS Options var awsOptions = Configuration.GetAWSOptions(); services.AddDefaultAWSOptions(awsOptions); var client = awsOptions.CreateServiceClient<IAmazonDynamoDB>(); var dynamoDbOptions = new DynamoDbOptions(); ConfigurationBinder.Bind(Configuration.GetSection("DynamoDbTables"), dynamoDbOptions); services.AddScoped<IDynamoDbManager<MyModel>>(provider => new DynamoDbManager<MyModel>(client, dynamoDbOptions.MyModel)); } public class DynamoDbManager<T> : DynamoDBContext, IDynamoDbManager<T> where T : class { private DynamoDBOperationConfig _config; public DynamoDbManager(IAmazonDynamoDB client, string tableName) : base(client) { _config = new DynamoDBOperationConfig() { OverrideTableName = tableName }; } }我的Appsettings.json是:
My Appsettings.json is as:
{ "AWS": { "Region": "us-east-1", "AwsId": "xxx", "AwsPassword": "xxx" }, "DynamoDbTables": { "MyModel": "MyTable" } }运行代码时,我得到了错误:
When I run my code I am getting the error:

很多事情,但没有使它起作用。
I have tried many things but not getting this to work.
我尝试过:
将个人资料设置为: Amazon.Runtime.AmazonServiceException:无法找到凭证
,还尝试设置环境变量:
And also tried settingup of environment variables:
> github/aws/aws-sdk-net/issues/499
但仍然无法克服此错误。
But still cannot get past this error.
推荐答案因此,当我们使用AWS开发工具包时,需要进行设置并提供一个AWS访问密钥&一个秘密的钥匙。从我遇到的情况来看,它不会直接从应用程序设置中读取。因此,我发现以下是可以用来设置这些凭据的两种工作方法。
So when we are using AWS SDK we need to setup and provide an AWS access key & a secret key. And from what I have come across it does not read directly from the app settings. So I found below are the two working methods with which you can set these credentials.
方法1 -使用凭据文件
您可以创建一个凭证文件并将凭证存储在此处。下面是文件的格式。
You can create a credentials file and store your credentials there. Below is the format of the file.
[default] aws_access_key_id = your id goes here aws_secret_access_key = your password goes here在上面的文件中,默认是您的个人资料名称。
In above file, "default" is the name of your profile.
创建以上文件后,需要在Appsettings.json文件中指定以下内容:
After creating the above file you need to specify the same in Appsettings.json file as:
"AWS": { "Profile": "default", "ProfilesLocation": "C:\\filelocation\\awscredentials", "Region": "us-east-1", }方法2 -设置和读取环境变量
Method 2 - Setting and Reading from Environment Variables
我们可以在我们的startup.cs文件中设置环境变量,如下所示:
We can setup the environment variables in our startup.cs file as below:
Environment.SetEnvironmentVariable("AWS_ACCESS_KEY_ID", Configuration["AWS:AwsId"]); Environment.SetEnvironmentVariable("AWS_SECRET_ACCESS_KEY", Configuration["AWS:AwsPassword"]); Environment.SetEnvironmentVariable("AWS_REGION", Configuration["AWS:Region"]);然后从我们的appSettings.json文件中读取以下变量:
And read these variables from our appSettings.json file as:
AWS": { "Region": "us-east-1", "AwsId": "xxxx", "AwsPassword": "xxxx" }更多推荐
