如何在URL中传递两个查询参数

Question

@Stateless
@Path("projection")
public class ProjectionManager {

@Inject
private ProjectionDAO projectionDAO;

@Inject
private UserContext userContext;

@GET
@Path("{projectionId}")
@Produces("application/json")
public String places(@PathParam("projectionId") String projectionId) {
    return projectionDAO.findById(Long.parseLong(projectionId)).getPlaces().toString();
}}

在此示例中,此服务的URL应为/ projection/projectionId,但我如何在此代码中访问具有两个或更多查询参数的服务:

@PUT
@Path("/buy")
public Response buyTicket(@QueryParam("projectionId") String projectionId, @QueryParam("place") String place) {
    Projection projection = projectionDAO.findById(Long.parseLong(projectionId));
    if(projection != null) {
        projectionDAO.buyTicket(projection, userContext.getCurrentUser(), Integer.parseInt(place));
    }

    return Response.noContent().build();
}

Answer 1

/buy?projectionId=value1&place=value2

查看https://en.wikipedia.org/wiki/Query_string了解更多信息。由于它是 HTTP PUT，您不能简单地在浏览器中打开该 URL，您可以编写一些简单的 REST 客户端或使用 Chrome 中的 Postman 等浏览器扩展程序。
