AWS SQS连接问题

Answer 1

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();

Answer 2

我建议使用AWS Java SDK V2 。在Android上工作时，它将允许您使用备用HTTP运行时，并避免与Apache客户端发生混乱。

AWS Java SDK V2存储库中的

GitHub Issue #1180解决了该主题。

具体来说，在模块级build.gradle中，添加依赖项：

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

现在，初始化SQS客户端：

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

AmazonSQSClientBuilder.defaultClient（）java.lang.NoSuchFieldError：没有类型为Lorg / apache / http / conn / ssl / AllowAllHostnameVerifier的静态字段INSTANCE
