多篇文章-上传文件

我正在尝试以编程方式而不是网站将文件上传到服务器。我已经成功访问​​了该网站，可以剪贴/解析不同的网页，但是上传文件时遇到问题。有问题的服务器正在使用带有Apache挂毯的剪纸。

这是相关的Java代码：

private String uploadFile (String params, String filePath, String HTML) throws Exception {

    String postUrl = getUploadUrl(HTML);
    File fileToUpload = new File(filePath);
    postUrl = "http://printing.**.ca:9191" + postUrl;
    String random = "";

    Random ran = new Random();
    for (int i = 0; i < 28; i++) {
        random = random + String.valueOf(ran.nextInt(9));
    }
    String boundry = "---------------------------" + random; 

    URL obj = new URL(postUrl);
    connection = (HttpURLConnection)obj.openConnection();

    connection.setUseCaches(false);
    connection.setRequestMethod("POST");
    connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundry);
    connection.setRequestProperty("Host", "printing.**.ca:9191");
    connection.setRequestProperty("User-Agent", USER_AGENT);
    connection
    .setRequestProperty("Accept",
            "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8");
    connection.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
    connection.setRequestProperty("Referer",
            "http://printing.**.ca:9191/app");
    connection.setRequestProperty("Connection", "keep-alive");

    for (String cookie : this.cookies) {
        connection.addRequestProperty("Cookie", cookie.split(";", 1)[0]);
    }
    connection.setDoInput(true);
    connection.setDoOutput(true);

    String fileType = getFileType(fileToUpload);

    PrintWriter writer = null;
    try {
        writer = new PrintWriter(new OutputStreamWriter(connection.getOutputStream()));
        writer.println(boundry);
        writer.println("Content-Disposition: " + "form-data; " + "name=\"file[]\"; " + "filename=\"" + fileToUpload.getName() + "\"");
        writer.println("Content-Type: " + fileType);
        writer.println();
        BufferedReader reader = null;

        try {
            reader = new BufferedReader(new InputStreamReader(new FileInputStream(fileToUpload)));


            for (String line; (line = reader.readLine()) != null;) {
                writer.print(line);
            }
        } finally {
            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException e) {}
            }

        }
        writer.println(boundry + "--");
    } finally {
        if (writer != null) {
            writer.close();
        }
    }
    int responseCode = connection.getResponseCode();

    BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
    StringBuffer buffer = new StringBuffer();
    String inputLine;
    while((inputLine = reader.readLine()) != null) {
        buffer.append(inputLine);
    }
    reader.close();
    return null;

我曾经用鲨鱼来比较成功的请求和失败的请求，但是我无法确定哪里出了问题。

这是成功的请求：

POST /upload/3229 HTTP/1.1

User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:33.0) Gecko/20100101 Firefox/33.0

Content-Type: application/vnd.ms-excel
**data***
-----------------------------8555452061745260577115383266--

这将返回200 / ok，然后触发：

POST /app HTTP/1.1
Host: printing.**.ca:9191
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:33.0) Gecko/20100101 Firefox/33.0

Content-Type: application/x-www-form-urlencoded
Content-Length: 66

service=direct%2F1%2FUserWebPrintUpload%2F%24Form%240&sp=S1&Form1=

这是我的请求中的数据包：

POST /upload/3239 HTTP/1.1
Content-Type: multipart/form-data; boundary=---------------------------6735033783816657573427817664

Content-Type: application/vnd.ms-excel
**data*
---------------------------6735033783816657573427817664--

然后我得到200 / ok的火力：

POST /app HTTP/1.1
User-Agent: Mozilla/5.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8

service=direct%2F1%2FUserWebPrintUpload%2F%24Form%240&sp=S1&Form1=

并在上传文件响应时出错。对于/ upload / 3239，我将刮除包含上传文件形式的HTML。该网站还使用Dropzone.js，但可以使用简单的上传表单进行回退。此外，对于会话cookie，字符“;” 在所有其他请求上发送，没有任何失败。我可以访问该网站，但似乎无法正确上传该文件。

想法？？
