从HTTP请求设置cookie

我使用HttpRequest获得正确的登录工作。它在我的吐司中打印登录页面的正确html形式(仅用于测试)。现在我想根据该请求设置一个cookie。这怎么可能? 如果有必要,我可以提供一些代码。

我已经了解了CookieManager类,但我怎样才能成功完成呢?

提前致谢!

我的代码:

    public String getPostRequest(String url, String user, String pass) {
    HttpClient postClient = new DefaultHttpClient();
    HttpPost httpPost = new HttpPost(url);
    HttpResponse response;

    try {
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
        nameValuePairs.add(new BasicNameValuePair("login", user));
        nameValuePairs.add(new BasicNameValuePair("pass", pass));
        httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs, HTTP.UTF_8));      

        response = postClient.execute(httpPost);

        if(response.getStatusLine().getStatusCode() == 200) {
            HttpEntity entity = response.getEntity();

            if (entity != null) {
                InputStream instream = entity.getContent();  
                String result = convertStreamToString(instream);                   
                instream.close();             

                return result;      
            }
        }
    } catch (Exception e) {}
    Toast.makeText(getApplicationContext(),
            "Connection failed",
            Toast.LENGTH_SHORT).show();
    return null; 
}

private String convertStreamToString(InputStream is) {
    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    StringBuilder sb = new StringBuilder();

    String line = null;
    try {
        while ((line = reader.readLine()) != null) {
            sb.append(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            is.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    return sb.toString();
}           

嗯,这就是它。 convertStreamToString()函数将InputStream转换为一个String(纯HTML代码),我“吐司”只是测试它(所以它工作),所以代码工作正常。现在设置cookie。 : - )

这就是我现在所达到的目标:

// inside my if (entity != null) statement
List<Cookie> cookies = postClient.getCookieStore().getCookies();
String result = cookies.get(1).toString();
                    return result;

当我登录时,CookieList id 1包含一个值,否则该值是标准值。所以现在我知道价值的差异,但我怎么能继续?
