Question

每次我尝试使用erlcloud_sns（亚马逊SNS）时都会出错

erlcloud_sns:list_topics_all().
erlcloud_sns:create_topic("Topic2fromerlConsole").
erlcloud_sns:publish_to_topic("arn:aws:sns:eu-west-1:XXXXXXXXXXXX:AuTopic" , "my message", "subj").

我收到一个错误

** exception error: {sns_error,{socket_error,{nxdomain,[{lhttpc_client,send_request,                                                                      1,                                                                       [{file,"src/lhttpc_client.erl"},{line,222}]},                                                        {lhttpc_client,execute,9,                                                                       [{file,"src/lhttpc_client.erl"},{line,171}]},                                                        {lhttpc_client,request,9,                                                                       [{file,"src/lhttpc_client.erl"},{line,93}]}]}}}
     in function  erlcloud_sns:sns_xml_request/3 (src/erlcloud_sns.erl, line 574)
     in call from erlcloud_sns:create_topic/2 (src/erlcloud_sns.erl, line 153)

ssl已启动，sns已成功配置

更新：

在我的域名fix之后，我收到错误＆＃34;永久移动＆＃34;

erlcloud_sns:publish_to_topic("arn:aws:sns:eu-west-1:XXXXXXXXXXXX:AuTopic" , "my message", "subj")..


Error: [lhttpc_client,211,"eu-west-1.console.aws.amazon.com",80,
        [binary,{packet,http},{active,false}],
        infinity,false]
** exception error: {sns_error,{http_error,301,"Moved Permanently",
                                           <<"<!DOCTYPE HTML PUBLIC \"-//IETF//DTD HTML 2.0//EN\">\n<html><head>\n<title>301 Moved Permanently"...>>}}

如何让erlcloud sns工作？任何建议都会有所帮助

s3的错误301在url名称中，但error codes

中的sns没有

更新-2

固定： 我指定了不正确的主机（＆＃34; sns.eu-west-1.console.aws.amazon.com＆＃34;）而不是＆＃34; sns.eu-west-1.amazonaws.com＆＃34;（正确的））

遇到类似的问题，经过一些挖掘后我发现它使用的是sns.amazonaws.com的默认主机，这是无法解析的。覆盖特定于地区的主机名，例如＆sns.us-west-2.amazonaws.com＆＃39; （或基于您的发布示例的eu-west-1）解决它。在进行配置时，请务必使用configure / 3来提供主机名。我使用Elixir的erlcloud，所以我的简单例子是：

sns_host = "sns.us-west-2.amazonaws.com" |> String.to_char_list
:erlcloud_sns.configure(access_key_id, secret_access_key, sns_host)

...最终允许我的list_topics返回有效信息，而不是nxdomain错误。希望这会有所帮助。

Erlang SNS亚马逊erlcloud失败了socket_error nxdomain，Amazon Moved Permanently
