使用HttpURLConnection在POST请求中发送多部分时获取406响应错误

Question

我正在尝试使用带有POST方法的multipart上传文件，使用HTTPURLConnection。我收到406响应错误。

实际上我想使用HttpURLConnection将以下curl请求转换为java代码：

$ curl -i --header "Content-type: application/octet-stream" POST --data-binary "@pathToFile/inputFile.jar" http://username:password@hostname:port/resources?queryParams

这是返回的Java代码406响应：

public static void main(String[] args) throws Exception {

    FileInputStream inputStreamToRuleAppArchive = null;
    OutputStream outputStreamToRequestBody = null;
    BufferedWriter httpRequestBodyWriter = null;
    try{

        // Connect to the web server endpoint
        URL serverUrl =
            new URL("hostname:port/resources");
        HttpURLConnection urlConnection = (HttpURLConnection) serverUrl.openConnection();

        String fileUrl = "inputFile.jar";
        File logFileToUpload = new File(fileUrl);

        // Indicate that we want to write to the HTTP request body
        urlConnection.setDoOutput(true);
        urlConnection.setRequestMethod("POST");
        urlConnection.addRequestProperty("Content-type", "application/octet-stream");
        urlConnection.setDoInput(true);

        String loginPassword = "username"+ ":" + "password";
        String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
        urlConnection.setRequestProperty ("Authorization", "Basic " + encoded);

        outputStreamToRequestBody = urlConnection.getOutputStream();
        httpRequestBodyWriter =
            new BufferedWriter(new OutputStreamWriter(outputStreamToRequestBody));

        // Write the actual file contents
        inputStreamToRuleAppArchive = new FileInputStream(logFileToUpload);

        int bytesRead;
        byte[] dataBuffer = new byte[1024];
        while((bytesRead = inputStreamToRuleAppArchive.read(dataBuffer)) != -1) {
            outputStreamToRequestBody.write(dataBuffer, 0, bytesRead);
        }

        urlConnection.connect();

        // Read response from web server, which will trigger the multipart HTTP request to be sent.
        BufferedReader httpResponseReader =
            new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
        String lineRead;
        while((lineRead = httpResponseReader.readLine()) != null) {
            System.out.println(lineRead);
        }

    } finally{
        // Close the streams
        inputStreamToRuleAppArchive.close();
        outputStreamToRequestBody.close();
        httpRequestBodyWriter.close();
    }
}

我在SO上搜索了许多其他问题并使用了这个MultiPartUtility类并面临同样的错误：http://www.codejava.net/java-se/networking/upload-files-by-sending-multipart-request-programmatically。
