How to read file from Azure SAS using Java
问题
我在Azure Blob Storage中有一个CSV文件的SAS URL。我需要下载该文件并将其写入SQL数据库。问题是，如何使用SAS URL下载文件。我尝试过使用`RestTemplate`，但是出现了`NullPointerException`。由于我对Java不太熟悉，无法解决这个问题。
String url = "https://orcatest.blob.core.windows.net/ABC/extract.csv?st=2020-04-";
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_OCTET_STREAM));
HttpEntity<String> entity = new HttpEntity<String>(headers);
ResponseEntity<String[]> response = restTemplate.exchange(link, HttpMethod.GET, entity, String[].class);
