Question

当我运行以下程序时，会发生无法找到凭据的异常

using (IAmazonS3 s3Client = new AmazonS3Client(RegionEndpoint.USWest2)) 
{                  
    PutObjectRequest request = new PutObjectRequest
    {
        BucketName = bucketName,
        Key = ps1,
        FilePath = path
    };

    PutObjectResponse response = s3Client.PutObject(request);
    richTextBox1.Text = response.ToString();
}

此外，我已经像这样配置了app.config：

<configuration>
   <appSettings>
      <add key="AWSProfileName" value="ashu"/>
      <add key="AWSProfilesLocation" value="C:\service_credential\credentials"/>
      <add key="AWSRegion" value="us-west-2" />
   </appSettings>
</configuration>

您不需要使用new来实例化客户端，执行此操作的最佳方法是使用AWSClientFactory和StoredProfileAWSCredentials来创建客户端。

SoredProfile方法，您必须确定个人资料名称以及是否存在。无论如何看到这个例子，告诉你如何弄清楚：https://blogs.aws.amazon.com/net/post/Tx1310VG2O81PSY/Referencing-Credentials-using-Profiles

var credentials = new StoredProfileAWSCredentials("ashu");

EnvirementCredential Approach ，您必须将AWSAccessKey和AWSSecretKey放入App.config / Web.config中，并且必须确保这一点和地区是正确的。

的App.config

<appSettings>
        <add key="AWSAccessKey" value="Access_KEY" />
        <add key="AWSSecretKey" value="Secret_KEY" />      
</appSettings>

var credentials = new EnvironmentAWSCredentials();

using (IAmazonS3 s3Client = AWSClientFactory.CreateAmazonS3Client(credentials, RegionEndpoint.USWest2)) 
{                  
    PutObjectRequest request = new PutObjectRequest
    {
        BucketName = bucketName,
        Key = ps1,
        FilePath = path
    };

    PutObjectResponse response = s3Client.PutObject(request);
    richTextBox1.Text = response.ToString();
}
