Android应用程序 - 通过HTTP POST谷歌授权 [英] Android application - Google Authorization via HTTP Post

问题描述

我只是想通过HTTP POST发送给我的谷歌帐户的认证数据。我已经建立了HTTPpost（URLen codeD ArrayList的名称 - 值对），并执行HttpClient的得到HTT presponse。然而，这是问题开始的地方，在HTT presponse我回去似乎异常随时我尝试调用它的相关方法（getStatusLine或getEntity）一回。我也试图检查空的反应，做一个简单的if（空）其他类型检查，但仍没有运气。

I am just trying to send my Google account authentication data via HTTP POST. I have built the HTTPpost (URLencoded the ArrayList name - value pair) and executed the HTTPClient to get the HTTPResponse. However this is where the problem starts, the HTTPResponse I get back seems to return an exception anytime I try to call one of its associated methods (getStatusLine or getEntity). I also tried to check for "null" response, by doing a simple "if (null) else" type checking, but still no luck.

这是问题，因为我使用的模拟器？

Is this problem because I am using the emulator?

-----更新-----

我还发现，我得到一个空指针的反应，从而导致该异常。所以，存在一个问题，我访问谷歌的API的方式。网址为https://www.google.com/accounts/ClientLogin和电子邮件和的passwd是两个参数，我使用POST请求。

I have found out that I am getting a NULL Pointer response, which causes the exception. So, there is an issue with the way I am accessing the Google API. The URL is "https://www.google.com/accounts/ClientLogin" and "Email" and "Passwd" are the two parameters I use for the POST request.

HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("<URL HERE>");

try {

    List<NameValuePair> parameters = new ArrayList<NameValuePair>(2);
    parameters.add(<name_value_pair>);
    parameters.add(<name_value_pair>); 
    httppost.setEntity(new UrlEncodedFormEntity(parameters));


    HttpResponse response = httpclient.execute(httppost);

    StatusLine returned_status = response.getStatusLine();
    int status_code = returned_status.getStatusCode();


} catch (ClientProtocolException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block
}

}

推荐答案

而不是使用httpPost使用的Htt prequest和放大器;也u必须使用一个名为的Base64及放库; Android版本2.1及放大器;上述

Instead using httpPost use HttpRequest & also u have to use a library called Base64 & Android version 2.1 &above

    String data;
    HttpParams httpParameters;


   HttpClient client;
    HttpResponse response;
    String userAuth;

    httpParameters = new BasicHttpParams();
                    String auth = android.util.Base64.encodeToString(
                            (username + ":" + userpwd).getBytes("UTF-8"), 
                            android.util.Base64.NO_WRAP
                        );
                        HttpGet request = new HttpGet(StaticURL.uMain+resourceURI);

                        request.addHeader("Authorization", "Basic "+ auth);

                    HttpConnectionParams.setSoTimeout(httpParameters, timeoutConnection);
                    client = new DefaultHttpClient(httpParameters);

                    response = client.execute(request);
                    userAuth = EntityUtils.toString(response.getEntity());

                    System.out.println("Data. in login.."+userAuth);
