使用 HttpPut 使文件上传请求不起作用

Question

我正在使用此代码向服务器（后端的 PHP）发出文件上传请求，

public String makeFilePutUploadRequest(String url,File file,List<BasicNameValuePair> basicNameValuePairs) throws ClientProtocolException, IOException {
    String responseString = null;

        HttpPut httput = new HttpPut(url);
        MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();
        //
        if (basicNameValuePairs.size() > 0) {
            for (BasicNameValuePair nameValuePair : basicNameValuePairs) {
                multipartEntityBuilder.addTextBody(nameValuePair.getName(), nameValuePair.getValue());
            }
        }
        // file
        multipartEntityBuilder.addPart("upfile", new FileBody(file));
        httput.setEntity(multipartEntityBuilder.build());
        HttpResponse response = httpClient.execute(httput);
        responseString = EntityUtils.toString(response.getEntity());

    //      Log.i(LOG_TAG, "response string recieved::" + responseString);
    return responseString;
}

但在服务器端收到请求但未设置参数。

我在后端使用 Laravel 4.1 来处理这个请求，如果我使用 Input::get('param') 来获取值，我会得到空值。而Input::hasFile('upfile') 返回false

要使用 PUT 方法发送参数，我这样做：

    HttpPut httput = new HttpPut();


    StringBuffer params = new StringBuffer();
    for (BasicNameValuePair nameValuePair : basicNameValuePairs) {
        params.append(nameValuePair.getName())
              .append("=")
              .append(nameValuePair.getValue())
              .append("&");
    }

    StringBuffer urlWithParams = new StringBuffer(ServiceURL);
    urlWithParams.append("?").append(params.toString().substring(0,params.length()-1));

    httput.setURI(URI.create(urlWithParams.toString()));
    httput.addHeader("Content-Type", "application/json");
