Question

亚马逊S3上托管了一个具有授权读取访问权限的视频，我在发送S3密钥时播放视频时出现了上述错误

日志

tech.glide.load.engine.GlideException: Failed to load resource

代码

val defaultHttpDataSourceFactory =
DefaultHttpDataSourceFactory("Mozilla/5.0 (Linux; U; Android 4.0.3; ko-kr; LG-L160L Build/IML74K) AppleWebkit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30").apply {
defaultRequestProperties.set("access_key", "")
defaultRequestProperties.set(
"secret_key",   "" )
defaultRequestProperties.set("bucket_name", "")
defaultRequestProperties.set("region", "")
}
return ProgressiveMediaSource.Factory(defaultHttpDataSourceFactory)
.createMediaSource(uri)

当检查网络探查器时，我发现请求正确地具有标头。

解决方案是生成辞职URL：

添加到build.gradle:旁边

implementation 'com.amazonaws:aws-android-sdk-s3:2.9.2'

object AmazonS3Helper {
fun getURI(objectName: String, s3: S3Credentials?): Uri? {

val myCredentials: AWSCredentials =
BasicAWSCredentials(s3?.accessKey, s3?.secretKey)
val s3client: AmazonS3 = AmazonS3Client(myCredentials)
val region = s3?.region ?: "eu-west-2"
s3client.setRegion(com.amazonaws.regions.Region.getRegion(region))
val request = GeneratePresignedUrlRequest(s3?.buckeName, objectName)
val objectURL: URL = s3client.generatePresignedUrl(request)
return Uri.parse(objectURL.toString())
}
}

然后使用uri作为exo播放器的正常使用

注意：S3Credentials它只是一个包装类，具有S3头值，如(bucket_name等(。
