curl上传文件

后端是用的multipart控件接收

curl -X'POST' url -F"param1=value1" -F "file=@/home/work/以父之名.pdf"

测试代码清单一

• curl

curl -XPOST http://localhost:8700/api/v1/ceph/upload/file/kbase -F "file=@/home/ubuntu/sun/father.pdf"

• Controller

@ResponseBody
@RequestMapping(value = "/upload/file/{bucketName}", method = RequestMethod.POST)
public void uploadFile(@RequestParam(value = "file") MultipartFile file
        , HttpServletRequest request, @PathVariable String bucketName) {

    logger.debug("Enter into uploadFile");
    // 1, 获取文件名称
    String fileName = file.getOriginalFilename();
    logger.debug("[CephController][uploadFile] fileName: {}", fileName);
    // 2, 构造objectKey, objectKey生成规则, resContentId:ts:fileNameEncodeStr
    StringBuffer objectKey = new StringBuffer();
    objectKey.append(System.currentTimeMillis())
            .append(":").append(fileName);
    String objectKeyEncodeStr = "";
    try {
        // 3, objectKey编码，":"在浏览器会被自动转义为%3a
        objectKeyEncodeStr = URLEncoder.encode(objectKey.toString(), "UTF-8");
    } catch (UnsupportedEncodingException e) {
        logger.debug("file name encode error: {}", e);
        throw new RuntimeException("Fail to parse file name");
    }
    logger.debug("[CephController][uploadFile] generate objectKey: {}, encode objectKey: {}"
            , objectKey.toString(), objectKeyEncodeStr);
    try {
        // 4, 获取文件流，将文件以流的方式上传到ceph
        InputStream inputStream = file.getInputStream();
        CephClient cephClient = new CephClient(endpoint, ak, sk);
        cephClient.putObject(bucketName, objectKeyEncodeStr, inputStream, null);
    } catch (IOException e) {
        logger.debug("[CephController][uploadFile][exception] upload ceph fail, e: {}", e);
        throw new RuntimeException("Fail upload file to ceph");
    }
}
