如何从文件中加载 AWS 凭证？

Question

我正在使用 IVONA SpeachCloud SDK（创建语音示例）：https://github.com/IvonaSoftware/ivona-speechcloud-sdk-java/blob/master/src/samples/IvonaSpeechCloudCreateSpeech/SampleIvonaSpeechCloudCreateSpeech.java

使用此代码设置类路径

private static IvonaSpeechCloudClient speechCloud;

private static void init() {
    speechCloud = new IvonaSpeechCloudClient(
            new ClasspathPropertiesFileCredentialsProvider("resources/IvonaCredentials.properties"));
    speechCloud.setEndpoint("https://tts.eu-west-1.ivonacloud.com");
}

以下是 ivona.properties 文件的格式。文件位于资源目​​录中。我在 SpeechCloud 帐户中获得的所需凭据

accessKey = mykey 
secretKey = mysecretKey

以下是我遇到的异常

Exception in thread "main" com.amazonaws.AmazonClientException: Unable to load AWS credentials from the /resources/ivona.properties file on the classpath
at com.amazonaws.auth.ClasspathPropertiesFileCredentialsProvider.getCredentials(ClasspathPropertiesFileCredentialsProvider.java:81)
at com.ivona.services.tts.IvonaSpeechCloudClient.prepareRequest(IvonaSpeechCloudClient.java:279)
at com.ivona.services.tts.IvonaSpeechCloudClient.prepareRequest(IvonaSpeechCloudClient.java:272)
at com.ivona.services.tts.IvonaSpeechCloudClient.invoke(IvonaSpeechCloudClient.java:259)
at com.ivona.services.tts.IvonaSpeechCloudClient.createSpeech(IvonaSpeechCloudClient.java:148)
at SampleIvonaSpeechCloudCreateSpeech.main(SampleIvonaSpeechCloudCreateSpeech.java:45

我该如何解决这个异常？谢谢。

好的，我在源文件中搞砸了几个小时后才明白这一点。您可以创建自己的提供程序类，您可以在其中将凭据作为字符串参数传递。

这是我的自定义凭证类“IvonaCredentials”

import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.AWSCredentialsProvider;

public class IvonaCredentials implements AWSCredentialsProvider{

public IvonaCredentials(String mSecretKey, String mAccessKey) {
    super();
    this.mSecretKey = mSecretKey;
    this.mAccessKey = mAccessKey;
}

private String mSecretKey;
private String mAccessKey;

@Override
public AWSCredentials getCredentials() {
    AWSCredentials awsCredentials = new AWSCredentials() {

        @Override
        public String getAWSSecretKey() {
            // TODO Auto-generated method stub
            return mSecretKey;
        }

        @Override
        public String getAWSAccessKeyId() {
            // TODO Auto-generated method stub
            return mAccessKey;
        };
    };
    return awsCredentials;
}

@Override
public void refresh() {
    // TODO Auto-generated method stub

}



}

我是这样称呼我的班级的

private static void init() {
    speechCloud = new IvonaSpeechCloudClient(new IvonaCredentials("secretKey", "accessKey"));
    speechCloud.setEndpoint("https://tts.eu-west-1.ivonacloud.com");
}

我的问题已经解决了！

我使用我的 secretKey 和 accessKey 自定义实现了 AWSCredentials 类
