Question

我的问题看起来像这样：当我向REST服务发送POST请求时，我得到了Access-Control-Allow-Origin错误，但请求GET它正在工作。

这是我的休息服务：

@Path("/createUser")
@RequestScoped
public class ClientRestService {

@Inject
private ClientManager clientManager;

@POST
@Path("{name}/{surname}/{adress}")
@Produces(MediaType.APPLICATION_JSON)
public Response createUser(@PathParam("name")String name,  @PathParam("surname")String surname, @PathParam("adress")String adress) {
    Client client = new Client(name,surname,adress);


    Response.ResponseBuilder builder = Response.ok("POST It's working.!!!");
    builder.header("Access-Control-Allow-Origin", "*");
    builder.header("Access-Control-Allow-Methods", "POST");
    return builder.build();
}

@GET
public Response getMetod() {
    Response.ResponseBuilder builder = Response.ok("GET It's working.");
    builder.header("Access-Control-Allow-Origin", "*");
    return builder.build();
}
}

这是客户：

$(document).ready(function() {

$.ajax({
    url: 'http://localhost:8080/Bank_Project_Test/MyApp/createUser',
    type: 'POST',
    data: 'name=SomeName'+
        '&surname=SomeSurname'+
        '&adress=SomeAdress', 
    success: function(success) {
        alert(success); 
    }
});
});

因为预测飞行请求可能会失败吗？

如果在事情失败时在浏览器中看到OPTIONS - 方法请求，那么您还需要处理服务器实现中的方法。
