java - HttpClient 自动上传文件到远程服务器

Question

我正在尝试通过在线网站转换许多 doc 文件，使用 HttpClient 来模拟 Http 请求

URI uri = new URI("http://www.docx2doc.com/convert/convert-file");

    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(uri);

    MultipartEntity reqEntity = new MultipartEntity(
        HttpMultipartMode.BROWSER_COMPATIBLE);


    reqEntity.addPart("email",new StringBody(""));
    reqEntity.addPart("input_type",new StringBody("doc"));
    reqEntity.addPart("output_type",new StringBody("html"));
    reqEntity.addPart("script",new StringBody("converters"));



    FileBody bin = new FileBody(
        new File("mydoc.docx"));
    reqEntity.addPart("input_file", bin );

    httppost.setEntity(reqEntity);`

帖子中的所有参数（电子邮件、输出类型...）都被服务器接受，但文件不接受...

我该如何处理？

谢谢你。
