java - 通过 Post Request 上传文件

Question

我正在尝试根据他们的 documentation 通过 HTTP Post 将图像上传到 SmugMug .我的所有 header 都是正确的，但让我感到困惑的部分是按照规定在正文中设置二进制数据:

This method requires a POST request with the binary data in the body and all other metadata in the headers.

我试过:

• SMResponse response = builder.post(SMResponse.class, Files.readAllBytes(image.toPath()));
  

• SMResponse response = builder.post(SMResponse.class, new String(Files.readAllBytes(image.toPath())));
  

• SMResponse response = builder.post(SMResponse.class, new String(Base64.encode(Files.readAllBytes(image.toPath()))));
  

• SMResponse response = builder.post(SMResponse.class, Base64.encode(Files.readAllBytes(image.toPath())));
  

我最好的猜测是第一个会起作用，但所有这些都会返回:

{"stat":"fail","method":"smugmug.images.upload","code":5,"message":"system error"}

这是上传的完整方法，以防我遗漏了什么:

public boolean upload(File image, int albumId, String caption, String keywords, 
        Boolean hidden, Integer imageId, Integer altitude, Float latitude, 
        Float longitude, boolean pretty) throws IOException, InvalidKeyException, NoSuchAlgorithmException, SmugMugException {
    logger.debug("upload() called");
    byte[] imageBytes = Files.readAllBytes(image.toPath());

    WebResource resource = SmugMugAPI.CLIENT.resource("http://upload.smugmug.com/");

    LoggingFilter logFilter = new LoggingFilter();
    resource.addFilter(logFilter);

    OAuthSecrets secrets = new OAuthSecrets().consumerSecret(smugmug.getConsumerSecret());
    OAuthParameters oauthParams = new OAuthParameters().consumerKey(smugmug.getCosumerKey()).
            signatureMethod("HMAC-SHA1").version("1.0");
    // Create the OAuth client filter
    OAuthClientFilter filter = new OAuthClientFilter(SmugMugAPI.CLIENT.getProviders(), oauthParams, secrets);
    // Add the filter to the resource
    if (smugmug.getToken() != null){
        secrets.setTokenSecret(smugmug.getToken().getSecret());
        oauthParams.token(smugmug.getToken().getId());
    }
    resource.addFilter(filter);

    WebResource.Builder builder = resource.getRequestBuilder();
    //User agent
    builder = builder.header("User-Agent", smugmug.getAppName());
    //API Version header
    builder = builder.header("X-Smug-Version", "1.3.0");
    //Response Type header
    builder = builder.header("X-Smug-ResponseType", "JSON");
    //Content-Length header
    builder = builder.header("Content-Length", Long.toString(image.length()));
    //Content-MD5 header
    builder = builder.header("Content-MD5", DigestUtils.md5Hex(imageBytes));
    //X-Smug-FileName header
    builder = builder.header("X-Smug-FileName", image.getName());
    //X-Smug-AlbumID header
    builder = builder.header("X-Smug-AlbumID", Integer.toString(albumId));
    //X-Smug-Caption header
    if(caption != null){
        builder = builder.header("X-Smug-Caption", caption);
    }
    //X-Smug-Caption header
    if(keywords != null){
        builder = builder.header("X-Smug-Keywords", keywords);
    }
    //X-Smug-Hidden header
    if(hidden != null){
        builder = builder.header("X-Smug-Hidden", hidden.toString());
    }
    //X-Smug-ImageID header
    if(imageId != null){
        builder = builder.header("X-Smug-ImageID", imageId.toString());
    }
    //X-Smug-Altitude header
    if(altitude != null){
        builder = builder.header("X-Smug-Altitude", altitude.toString());
    }
    //X-Smug-Latitude header
    if(latitude != null){
        builder = builder.header("X-Smug-Latitude", latitude.toString());
    }
    //X-Smug-Latitude header
    if(longitude != null){
        builder = builder.header("X-Smug-Longitude", longitude.toString());
    }
    //X-Smug-Pretty header
    if(pretty){
        builder = builder.header("X-Smug-Pretty", Boolean.toString(pretty));
    }

    SMResponse response = builder.post(SMResponse.class, new String(imageBytes));
    if (!"ok".equals(response.getStat())) {
        throw new SmugMugException(response);
    }
    return true;
}

我哪里做错了？

尝试只是为了查看响应:

SMResponse response = builder.entity(image).post(SMResponse.class);

它实际上发回了一个空白响应(没有 json)，这本身就很奇怪，正如我所期望的那样。这是输出:

Answer 1

我不太确定发生了什么，但在 SmugMug 帐户设置中找到上传日志后，我能够让它正常工作(要到达那里，请转到工具 -> 帐户设置 -> 统计 -> 上传 -> 详细信息) .请注意，在上传日志中，有一个切换选项可仅显示错误或所有上传。

现在开始实际回答如何设置 Post 请求的实际“正文”。实际格式应该是我发布的第一个:

SMResponse response = builder.post(SMResponse.class, Files.readAllBytes(image.toPath()));

所以要么我搞砸了，认为它在正常工作时没有工作，当时 smugmug 端有问题，要么我的代码中有其他错误，但在我的过程中得到了修复试图解决这个非问题。
