关于java:文件上传

@PostMapping("/upload")    public String upload(@RequestParam("abc") MultipartFile file, HttpServletRequest request) {        System.out.println("==============" + request.getContentType());        String uploadPath = "/Users/test";        String originalFileName = file.getOriginalFilename();        File local = new File(uploadPath + "/" + originalFileName);        try {            file.transferTo(local);        } catch (IllegalStateException e) {        } catch (IOException e) {        }        return originalFileName;    }

应用curl上传：

curl -i  -F "abc=@TLS.md" -X POST  http://127.0.0.1:8080/upload

非form模式：

@PostMapping("/binary")    public void binary(HttpServletRequest request) throws IOException {        File destination = new File("/Users/test/abc");        ServletInputStream inputStream = request.getInputStream();        Enumeration<String> ens = request.getHeaderNames();        ens.asIterator().forEachRemaining(t -> System.out.println(t + ":" + request.getHeader(t)));        FileUtils.copyInputStreamToFile(inputStream, destination);    }

应用curl上传

curl --data-binary  @TLS.md  http://127.0.0.1:8080/binary
