java - 无法加载 AWS Ivona 属性文件 Java

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("IvonaCredentials.properties"));
    speechCloud.setEndpoint("https://tts.eu-west-1.ivonacloud.com");
}

以下是 ivona.properties 文件的格式。文件位于基本目录中。我的 SpeechCloud 帐户中拥有所需的凭据

accessKey = mykey 
secretKey = mysecretKey

下面是我遇到的异常

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.createSpeech(IvonaSpeechCloudClient.java:148)
at SampleIvonaSpeechCloudCreateSpeech.main(SampleIvonaSpeechCloudCreateSpeech.java:45

我怎样才能解决这个异常，或者我怎样才能创建一个类来解决这个问题并手动输入我的accessKey和secretKey作为字符串。谢谢。

好吧，在对源文件进行了几个小时的研究之后，我发现了这一点。您可以创建自己的提供程序类，在其中可以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

}



}

这就是我如何称呼我的类(class)

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