HttpContext 不保存 cookie

Question

我正在尝试使用 cookie 在我的 Android 应用上保持会话，但我似乎遇到了问题，因为我从未收到来自服务器的预期响应。

起初我有一个登录例程，它按预期运行并返回所有预期数据。

我的登录请求：

        HttpContext httpContext = new BasicHttpContext();
        HttpResponse response;
        HttpClient client = new DefaultHttpClient();
        String url = context.getString(R.string.url_login);
        HttpPost  connection = new HttpPost(url); 
        connection.setHeader("Content-Type","application/x-www-form-urlencoded");
        List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(2);
        nameValuePair.add(new BasicNameValuePair(PARAM_LOGIN,params[0]));
        nameValuePair.add(new BasicNameValuePair(PARAM_PASSWORD,params[1]));
        connection.setEntity(new UrlEncodedFormEntity(nameValuePair,"UTF-8"));
        response = client.execute(connection,httpContext);
        data = EntityUtils.toString(response.getEntity());

在我做出回应后，我只是用数据做我需要的东西，然后事情就开始崩溃了。因为现在我只是想在同一个 AsyncTask 中调用我的服务器来测试我的 cookie 是否正确保存在我的 HttpContext 上。

一开始我只是调用了我的 URL，没有做任何更改，只是重用了我当前的 HttpContext：

        HttpPost httpPost = new HttpPost(context.getString(R.string.url_cookie_test)); 
        HttpResponse response = client.execute(httpPost, httpContext);

由于此测试失败，我测试了在我的 HttpPost 标头上添加我的 cookie 值：

       httpPost.addHeader(context.getString(R.string.domain),PHPSESSID+"="+cookieID+";");

然后我尝试创建一个新的 HttpContext 并强制 COOKIE_STORE：

        CookieStore cookieStore = new BasicCookieStore();
        BasicClientCookie cookie = new BasicClientCookie(PHPSESSID, cookieID);
        cookieStore.addCookie(cookie);
        HttpContext localContext = new BasicHttpContext();
        localContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);

        HttpResponse response;
        HttpClient client = new DefaultHttpClient();
        HttpPost  httpPost = new HttpPost(context.getString(R.string.url_cookie_test));
        response = client.execute(connection,localContext);

一切都失败了，我已经确认，当我第一次收到登录响应时，我从 cookie 中获得了预期的数据，如下所示：

        List<Cookie> cookies = ((AbstractHttpClient) client).getCookieStore().getCookies();
        for (Cookie cookie: cookies){
             Log.i("Cookie Value",cookie.toString());
             /*
              Prints:[[version: 0][name: PHPSESSID][value: 2ebbr87lsd9077m79n842hdgl3][domain: mydomain.org][path: /][expiry: null]]
             */
        }

我已经在 StackOverflow 上进行了搜索，我发现了很多对我来说并不适用的解决方案，我将分享我已经尝试过的所有解决方案：

正如我告诉你的，这里是这段代码，用于将 httpPost 发送到使用 Spring MVC 开发的服务器，并带有 API REST。请考虑以这种方式构建您的请求：

请，注意cmets。您应该根据您的情况对其进行调整；）。您也可以将此代码包含在方法或您喜欢的任何内容中。

try {

        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("yourPath");

        //NameValuePairs is  build with the params for your request

        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        httppost.setHeader("Content-Type",
                "application/x-www-form-urlencoded");

        CookieStore cookieStore = new BasicCookieStore();

        //cookie is a variable that I stored in my shared preferences.
        //You have to send in it every request
        //In your case, JSESSIONID should change, because it's for Java.
        //Maybe it could be "PHPSESSID"
        BasicClientCookie c = new BasicClientCookie("JSESSIONID", cookie);

        //JSESSIONID: same comment as before.
        httppost.setHeader("Cookie", "JSESSIONID="+cookie);

        cookieStore.addCookie(c);
        ((AbstractHttpClient)httpclient).setCookieStore(cookieStore);

        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
    } catch (Exception e) {
        Log.e("log_tag", "Error in http connection" + e.toString());
    }

我希望这会有所帮助！在“旧”项目中很难找到它:)
