退出HttpClient会话

问题描述

如何退出HttpClient会话?

How to exit from HttpClient session?

我使用以下代码使用Apache HttpClient登录到应用程序

I use the following code to login to the application using Apache HttpClient

public HttpClient loginToHexgen(String username, String password) {
        HttpClient client = new DefaultHttpClient();

        // send post url to login to  hexgen
        HttpPost post = new HttpPost("http://localhost:8080/j_spring_security_check");

        try {
            // set the user name and password
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
            nameValuePairs.add(new BasicNameValuePair("j_username", username));
            nameValuePairs.add(new BasicNameValuePair("j_password", password));

            post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            HttpResponse response = client.execute(post);

            HttpEntity entity = response.getEntity();

            if (entity != null) {
                post.abort();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return client;
    }

类似于以下内容:

HttpClient client = new DefaultHttpClient();
client= httpRequest.loginToHexgen("mayank", "hexgen");

此处httpRequest是使用loginToHexgen方法的类.

如果我要使用具有不同用户名和密码的多个用户登录系统，怎么办?.

If I want to login to the system with multiple user with diffrent user name and password how to do this?.

例如，在同一会话中，我要注销一个用户并使用另一用户登录.

Like for example in the same session I want to logout one user and login using other user.

推荐答案

您可以使用一种解决方法–使用新的cookieStore向新用户发送请求.

You may use a workaround – to send a request to a new user with a new cookieStore.

// Create a local instance of cookie store
cookieStore = new BasicCookieStore();
// Set the store
httpClient.setCookieStore(cookieStore);

服务器将与您的新用户打开一个新会话.请注意，旧的会议不会关闭.我不建议使用这种方式.

Server will open a new session to your new user. Please note that the old session will NOT be closed.I do not recommend to use this way.

会话管理在服务器端执行–您不能在客户端执行此操作.我建议在测试结束时，您应调用服务器URL，这将使服务器端的会话无效.(通常，使用表单身份验证的应用程序具有注销功能，您只需要使用它即可)

The session management is performed on the server side – you can not do it on the client side.I recommend in the end of your test you should call to a server URL that will invalidate a session on the server side.(Generally applications that use Form authentication have a logout functionality and you just need to use it)
