AWS SQS 連接問題

Answer 1

我建議使用 AWS Java SDK V2 。 在 Android 上工作時，它將允許您使用備用 HTTP 運行時，並避免 Apache 客戶端的一些混亂。

AWS Java SDK V2 存儲庫中的GitHub 問題 #1180解決了此主題。

具體來說，在您的模塊級build.gradle中，添加依賴項：

dependencies {
    implementation 'software.amazon.awssdk:sqs:2.13.49'
    implementation 'software.amazon.awssdk:url-connection-client:2.13.49'
}

現在，初始化 SQS 客戶端：

val sqs = SqsClient.builder()
    .httpClient(UrlConnectionHttpClient.create())
    .region(Region.US_EAST_1)
    .credentialsProvider(yourCredentialsHere())
    .build()

Answer 2

它的工作。

     ProfileCredentialsProvider credentialsProvider = new ProfileCredentialsProvider();

    try {

        credentialsProvider.getCredentials();
    } catch (Exception e) {
        throw new AmazonClientException(
                "Cannot load the credentials from the credential profiles file. " +
                        "Please make sure that your credentials file is at the correct " +
                        "location (~/.aws/credentials), and is in valid format.",
                e);

    }
    AmazonSQS sqs = AmazonSQSClientBuilder.standard()
            .withCredentials(credentialsProvider)
            .withRegion(Regions.US_WEST_2)
            .build();
