如何从 S3 链接获取文件 - java

Question

如何在 Java 中从 Amazon 文件路径获取文件。它总是返回（文件名、目录名或卷标语法不正确）错误。如果我提供本地路径，它会完美运行。这是我的代码

FileInputStream fis;
            String filePath = "https://mydomain:8080/S3DOC/?filename=/folder/DEV/Portal/sample.doc";
            if(FilePath.substring(FilePath.length() -1).equals("x")){ //is a docx
                System.out.println("docx");
            try {
                fis = new FileInputStream(new File(FilePath));
                XWPFDocument doc = new XWPFDocument(fis);
                XWPFWordExtractor extract = new XWPFWordExtractor(doc);
                System.out.println(extract.getText());
            } catch (IOException e) {

                e.printStackTrace();
            }
            } else { //is not a docx
                System.out.println("doc");
                try {
                    fis = new FileInputStream(new File(FilePath));
                    HWPFDocument doc = new HWPFDocument(fis);
                    WordExtractor extractor = new WordExtractor(doc);
                    System.out.println(extractor.getText());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

错误：java.io.FileNotFoundException: https:\mydomain:8080\S3DOC\?filename=\folder\DEV\Portal\sample.doc（文件名、目录名或卷标语法不正确）

s3 路径如：s3://bucket/key

你可以使用

 AmazonS3Client.getObject(String bucketName, String key);

获取一个S3Object，然后获取InputStream。
