从android上传文件到亚马逊S3 url？

dependencies {
    implementation 'com.amazonaws:aws-android-sdk-s3:2.16.0'
}

BasicAWSCredentials credentials = new BasicAWSCredentials("Access Key", "Secret Key");
AmazonS3Client s3Client = new AmazonS3Client(credentials);

File file = new File("path/to/your/file");
String bucketName = "your-bucket-name";
String key = "path/in/bucket/filename";

s3Client.putObject(bucketName, key, file);

Date expiration = new Date(System.currentTimeMillis() + 3600000); // 设置URL的过期时间
GeneratePresignedUrlRequest generatePresignedUrlRequest = new GeneratePresignedUrlRequest(bucketName, key)
        .withMethod(HttpMethod.GET)
        .withExpiration(expiration);

URL url = s3Client.generatePresignedUrl(generatePresignedUrlRequest);
