如何在 Apache HttpClient 4.1 中处理会话 [英] How to Handle the Session in Apache HttpClient 4.1

问题描述

我正在使用 HttpClient 4.1.1 来测试我服务器的 REST API.

I am using the HttpClient 4.1.1 to test my server's REST API.

我可以设法登录似乎工作正常，但是当我尝试做其他任何事情时我都失败了.

I can manage to login seem to work fine but when I try to do anything else I am failing.

很可能是我在下一个请求中设置 cookie 时遇到问题.

Most likely I have a problem setting the cookie in the next request.

这是我目前的代码:

HttpGet httpGet = new HttpGet(<my server login URL>);
httpResponse = httpClient.execute(httpGet)
sessionID = httpResponse.getFirstHeader("Set-Cookie").getValue();
httpGet.addHeader("Cookie", sessionID);
httpClient.execute(httpGet);

是否有更好的方法来管理 HttpClient 包中的 session/cookies 设置?

Is there a better way to manage the session/cookies setting in the HttpClient package?

推荐答案

正确的做法是准备一个CookieStore 需要在 HttpContext 依次传递给每个 HttpClient#execute() 调用.

The correct way is to prepare a CookieStore which you need to set in the HttpContext which you in turn pass on every HttpClient#execute() call.

HttpClient httpClient = new DefaultHttpClient();
CookieStore cookieStore = new BasicCookieStore();
HttpContext httpContext = new BasicHttpContext();
httpContext.setAttribute(HttpClientContext.COOKIE_STORE, cookieStore);
// ...

HttpResponse response1 = httpClient.execute(method1, httpContext);
// ...

HttpResponse response2 = httpClient.execute(method2, httpContext);
// ...
