Java 使用curl将文件上载到Box API

我尝试使用Box API将文件上载到Box。但是无论我尝试什么，我总是在没有任何其他信息的情况下收到

400个错误请求。你知道这个问题吗

卷曲\
-H“授权：承载访问\u令牌”-X POST\
-F attributes='{“name”：“tigers.jpeg”，“parent”：{“id”：“11446498”}'\
-F file=@myfile.jpg

我得到了解决方案，现在它的上传成功与小变化。这里的问题是如何正确管理contentDisposition

try {
    String url = "https://upload.box.com/api/2.0/files/content";
    WebResource resource = client.resource(url);

    JSONObject parentInput = new JSONObject();
    parentInput.put("id", "0");

    JSONObject inputJson = new JSONObject();
    fileName = fileName.trim();
    inputJson.put("name", fileName);
    inputJson.put("parent", parentInput);
    input = inputJson.toString();

    FormDataMultiPart form = new FormDataMultiPart();

    String cdMeta = "form-data; name=\"metadata\";";
    String cdFile = "form-data; name=\"content\"; 
    filename = \"" + fileName + "\";";


    FormDataContentDisposition cdmetaObj = new FormDataContentDisposition(cdMeta);
    FormDataBodyPart metaDdbpart = new FormDataBodyPart(cdmetaObj, input);
    form.bodyPart(metaDdbpart);

    FormDataContentDisposition cdFileObj = new FormDataContentDisposition(cdFile);

    FormDataBodyPart fileDdbpart = new FormDataBodyPart("file", inputStream,
        MediaType.APPLICATION_OCTET_STREAM_TYPE);

    fileDdbpart.setContentDisposition(cdFileObj);
    form.bodyPart(fileDdbpart);

    //Here we are using builder for executing client request

    Builder builder = resource.header("Content-Type",
        MediaType.MULTIPART_FORM_DATA).header("Authorization", "Bearer " + accessToken);
    ClientResponse response = builder.post(ClientResponse.class, form);
    String result = response.getEntity(String.class);
} catch (Exception e) {
    e.printStackTrace(e);
}
}

该错误可能与格式错误的JSON数据有关。我建议您从复选框文档开始。
try {
    String url = "https://upload.box.com/api/2.0/files/content";
    WebResource resource = client.resource(url);

    JSONObject inputJson = new JSONObject();
    fileName = fileName.trim();
    inputJson.put("name", fileName);
    inputJson.put("parent", parentInput);
    input = inputJson.toString();

    FormDataMultiPart form = new FormDataMultiPart();

    String cdMeta = "form-data; name=\"metadata\";";
    String cdFile = "form-data; name=\"content\";
