我有登录活动,我必须为我的网站创建一个帖子请求,以便将用户登录到我的移动应用程序中。要在我的网站上创建帖子请求,我需要使用csrf cookie作为参数,这意味着我首先从我的URL获取cookie并在创建带有csrf值的post请求后。

这是我的代码:

        HttpClient client = new DefaultHttpClient();

        HttpPost post = new HttpPost("http://192.168.178.163:8080/login/");

        try {

            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
            nameValuePairs.add(new BasicNameValuePair("username", "xxx"));
            nameValuePairs.add(new BasicNameValuePair("password", "yyy"));
            //csrfmiddlewaretoken
            String res = null;

            post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = client.execute(post);
            res = response.toString();
            res = res.replaceAll("\\s+","");
            BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

            String line = "";
            while ((line = rd.readLine()) != null) {
                Log.i("line", line);
                //System.out.println(line);
                if (line.startsWith("csrftoken=")) {
                    String key = line.substring(5);
                    Log.i("key", key);
                }

            }
        }
        catch (IOException e) {
            txt_Error.setText(e.toString());
        }

知道怎么做吗?我已经阅读过关于CookieSyncManager的内容,但我根本不明白......任何想法或代码示例都会非常清楚

HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://192.168.178.163:8080/login/");
CookieStore cookieStore = new BasicCookieStore();
HttpContext context = new BasicHttpContext();
context.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
...
HttpResponse response = client.execute(post, context);
List<Cookie> cookies = cookieStore.getCookies();
CookieMonster.eat(cookies); // :)

首先要获得csrftoken,(正如您在问题中提到的那样)。 AFAIK你还必须在帖子请求中发布csrftoken作为数据,后端将检查/匹配cookie和帖子数据。

例如,对于django后端,您必须添加以下内容:

nameValuePairs.add(new BasicNameValuePair("csrfmiddlewaretoken", "OBTAINED_TOKEN"));

如果来自http://192.168.178.163:8080/login/的获取请求返回表单,您可以检查源,它可能包含一个隐藏字段,其中包含您需要发送的令牌的名称/值。

希望这有帮助
