如何维护状态 Jersey 客户端

    { //
      //      Some session logic 
      //
     } 
        Client client = ClientBuilder.newClient();
        WebTarget baseTarget =
        client.target("https");
        /
        MultivaluedMap<String, String> formData = new 
        MultivaluedHashMap<String, String>();
        formData.add("usr", "@gmail.com");
        formData.add("pwd", "mat");
        Response response = baseTarget.request().post(Entity.form(formData))  
        System.out.println("----Second-time--method invoked GET-------");

        Response resp_sec = base2Target.request().get(); //second time in session perform action client side

看看这是否有帮助。这段代码为我提供了一个模板。希望它对你有用。

您首先需要从初始响应中获取 cookie。这些将是 NewCookie 实例，它们是服务器发送给客户端的 cookie，作为 Set-Cookie 标头。在客户端，您需要将Cookie 发送回服务器，这将导致发送Cookie 标头。如果您尝试在客户端上设置NewCookie，它将设置Set-Cookie 标头，这是错误的。您只需调用newCookie.toCookie() 即可轻松地将NewCookie 转换为Cookie

Map<String, NewCookie> cookies = response.getCookies();
Invocation.Builder ib = baseTarget.request();
for (NewCookie cookie: cookies.values()) {
    ib.cookie(cookie.toCookie());
}
Response response = ib.get();
