amazon-sns .net c#

尝试使用 AWS SDK for .NET /1.1.0.1使用类似于以下代码:

AddPermissionRequest request = new AddPermissionRequest()
    .WithActionNames(new[] { "Publish" })
    .WithAWSAccountIds(new[] { "xxx" })
    .WithLabel("PrincipleAllowControl")
    .WithTopicArn(resourceName);
client.AddPermission(request);

<ErrorResponse xmlns=" http://sns.amazonaws.com/doc/2010-03-31/">
  <Error>
    <Type>Sender</Type>
    <Code>ValidationError</Code>
    <Message>2 validation errors detected: Value null at 'actionName' failed to satisfy constraint: Member must not be null; Value null at 'aWSAccountId' failed to satisfy constraint: Member must not be null</Message>
  </Error>
  <RequestId>45054159-e46b-11df-9b30-693941920fe7</RequestId>
</ErrorResponse>

更新 This has been resolved 在最新版本的.NET API中,因此任何仍然遇到此问题的人都应该升级到 1.1.1 version

我花了一段时间才弄清楚发生了什么,结果我不得不使用客户端的HTTP版本 Wireshark 去观察发生了什么,但是在AWS SDK for.NET/1.1.0.1中似乎有一个bug。当我使用 AWS SDK for Java

AddPermissionRequest permissionRequest = new AddPermissionRequest()
   .withActionNames("Publish")
   .withAWSAccountIds("xxx")
   .withLabel("PrincipleAllowControl")
   .withTopicArn(resourceName);
client.addPermission(permissionRequest);

通过Wireshark观看发生的事情,发现了以下内容,为了清晰起见,进行了一些小的审查和编辑:

如您所见,AWS SDK for.NET正在使用AWSAccountId和ActionNames进行调用,而AWS Java SDK使用AWSAccountId和ActionName来解释返回的错误消息。
