jax-rs retrieve form parameters
提问by Brian DiCasa
I'm trying to retrieve some parameters that are passed to jax-rs from a posted form with the HttpServletRequest. However, my request object is always returning null values for my parameters. Am I not going about this the right way? I've posted the code below, along with an example request that is getting sent.
我正在尝试从带有 HttpServletRequest 的已发布表单中检索传递给 jax-rs 的一些参数。但是，我的请求对象总是为我的参数返回空值。我不是以正确的方式解决这个问题吗？我已经发布了下面的代码，以及正在发送的示例请求。
Here is my service:
这是我的服务：
@Path("/")
@Stateless
public class HomeController {
@Context
private HttpServletRequest request;
@Context
private HttpServletResponse response;
@EJB
private LoginServiceLocal loginService;
@POST
@Path("/authenticate")
@Consumes("application/x-www-form-urlencoded")
public void authenticate() throws Exception {
String email = request.getParameter("email");
String password = request.getParameter("password");
if (loginService.authenticate(email, password)) {
response.sendRedirect("/app");
} else {
request.setAttribute("authenticationError", "Invalid email/password.");
}
}
}
