Java-Android-如何将txt文件上传到网站？

我想将txt文件上传到网站,我承认我没有对其进行任何详细的研究,但是我看了一些示例,并希望就我是否朝着正确的方向提出更多的经验性意见. .

这是我到目前为止的内容：

DefaultHttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
private String ret;

HttpResponse response = null;
HttpPost httpPost = null;


public String postPage(String url,String data,boolean returnAddr) {

    ret = null;

    httpClient.getParams().setParameter(ClientPNames.COOKIE_POLICY,CookiePolicy.RFC_2109);

    httpPost = new HttpPost(url);
    response = null;

    StringEntity tmp = null;         

    try {
        tmp = new StringEntity(data,"UTF-8");
    } catch (UnsupportedEncodingException e) {
        System.out.println("HTTPHelp : UnsupportedEncodingException : "+e);
    }

    httpPost.setEntity(tmp);

    try {
        response = httpClient.execute(httpPost,localContext);
    } catch (ClientProtocolException e) {
        System.out.println("HTTPHelp : ClientProtocolException : "+e);
    } catch (IOException e) {
        System.out.println("HTTPHelp : IOException : "+e);
    } 
            ret = response.getStatusLine().toString();

            return ret;
}

我称之为：

postPage("http://www.testwebsite.com","data/data/com.testxmlpost.xml/files/logging.txt",true));

我希望能够将文件从设备上传到网站.

但是当以这种方式尝试时,我得到以下响应.

HTTP/1.1 405 Method Not Allowed

我是在尝试正确的方法还是应该以其他方式进行操作？
