从带有标头的 android 设备调用 HTTPS Web 服务以进行验证

Question

我想从 Android 设备调用 HTTPS 网络服务。其中包含用于验证服务器上数据的标头。我不知道如何调用用 java 编写的 https 网络服务。如果有人解释可能对我有帮助的步骤。谢谢你！

请检查此方法：

private static Header[] headers;
private String executeRequest(Httpget request)
        throws SocketTimeoutException {
    String responce = null;

    try {

        HttpParams httpParameters = new BasicHttpParams();
        // Set the timeout in milliseconds until a connection is
        // established.
        int timeoutConnection = 120000;
        HttpConnectionParams.setConnectionTimeout(httpParameters,
                timeoutConnection);
        // Set the default socket timeout (SO_TIMEOUT)
        // in milliseconds which is the timeout for waiting for data.
        int timeoutSocket = 120000;
        HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket);
        HttpClient httpclient = new DefaultHttpClient(httpParameters);
        HttpResponse httpResponse = httpclient.execute(request);
        // Obtain and Set Headers when login
        headers = null;
        headers = httpResponse.getAllHeaders();
        responseCode = httpResponse.getStatusLine().getStatusCode();
        responce = EntityUtils.toString(httpResponse.getEntity());
    } catch (ParseException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return responce;

}

Header previousHeader;

// used to add headers manually that we got from the response but now it is
// done automatically
@SuppressWarnings("unused")
private HttpUriRequest addHeaders(HttpUriRequest request) {
    for (int i = 0; headers != null && i < headers.length; i++) {

            request.setHeader(headers[i].getName(), headers[i].getValue());

    }
    // request.addHeader("Content-Length", "");
    return request;

}
