HsbGitHub opened a new issue #1184: 文件下载经过Edge网关后，报错提示content-type not supported
URL: https://github.com/apache/servicecomb-java-chassis/issues/1184
 
 
   文件下载经过Edge网关后，报错提示content-type not supported，不走网关是可以的。
   错误提示：
   {
       "message": "method GET, path /netdisk/file_download/, statusCode 200, reasonPhrase OK, response content-type application/octet-stream is not supported"
   }
   
   接口代码：
   @ApiResponses({
               @ApiResponse(code = 200, response = File.class, message = "")
       })
       @GetMapping(value = "/file_download")
       public ResponseEntity<InputStream> fileDownload(InvocationContext ic , FileDownloadReq req) {
           String fileName = req.getFileName();
           String fileStr = super.doFileDownload(OutApiServerEnum.TY_HUI_JIAO_YUN.getValue(), ic, fileName);
   
           return ResponseEntity
                   .ok().header(HttpHeaders.CONTENT_TYPE, MediaType.APPLICATION_OCTET_STREAM_VALUE)
                   .header(HttpHeaders.CONTENT_DISPOSITION, "attachment;filename="+fileName)
                   .body(new ByteArrayInputStream(fileStr.getBytes()));
       }
