JAX-RS @CookieParam Ionic 客户端不发送 cookie（电容器）

Question

我在 headers 中发送一个带有注释 @CookieParam 的 cookie 作为参数。

第一步：register/start

    @GET
    @Path("/start")
    @Produces(MediaType.APPLICATION_JSON)
    @NoCache
    public Response start() {
        try {
            String myIdentifier = "abcdefghijkl123456789";

            LOGGER.info(String.format("My identifier: %s ", myIdentifier)); 

            // the identifier is send through the cookies in headers
            NewCookie cookie = new NewCookie("myIdentifierCookie", myIdentifier, null, null, null,
                    1200, false, false);
            return Response.ok().cookie(cookie).build();
        }catch (Exception e) {
            return Response.status(500).build();
        }
    }

从现在开始就好了。当我执行 GET 时，我可以在响应 Headers 上读取我的 cookie。现在我正在做一个 POST 方法来检查收到的电子邮件，其中有 @CookieParam 注释。

    @POST
    @Path("/email")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    @NoCache
    public Response emailCheck(@CookieParam("myIdentifierCookie") Cookie identifierCookie,
                                  CheckEmailRequest request) {

        String identifier = "";
        try {
            identifier = identifierCookie.getValue();
        } catch (Exception e) {
            LOGGER.error("exception e ", e);
            LOGGER.error(String.format("Invalid  request identifier: %s ", identifier));
            return Response.status(500).build();
        }
    }

我的 cookie 值为空，我收到：

我的实现有误吗？
非常感谢。

我用的是哪个客户端？

我正在使用 Ionic with Angular，我的插件是来自 @angular/common/http 的 angular Http 模块。我有一个这样定义的 backend service :

  get(url, options?): Observable<any> {
    options = { ...options, withCredentials: true };
    return this.http.get(myURL, options);
  }

  post(url, body, options?): Observable<any> {
    options = { ...options, withCredentials: true };
    return this.http.post(myURL, body, options);
  }

所以在我的组件上，我是这样使用它的：

  public getRegistrationStart() {
    return this.backendService.get('/register/start', {
      observe: 'response',
    });
  }

  public emailStep(email) {
    const headers = new HttpHeaders().set('Content-Type', 'application/json');
    return this.backendService.postPublic('/register/email', email, {
      observe: 'response',
      headers,
    });
  }

我的电子邮件以 JSON 形式发送，例如 {"email":"test@test.test"}

这是我的开始请求的屏幕，服务器响应 Set-Cookie 包含我的 cookie（我已经设置了一个随机数生成器），但我的 cookie 在这里。

Answer 1

问题不是 JAX RS，而是离子电容器阻止了 cookie。通过在 capacitor.config.json 中添加此行解决了问题：

"server":{"hostname":"mydomain"}

Cookie 在 Android 中未被拦截，它在 iOS 中被拦截，因此仅在 iOS 构建文件中的 capacitor.config.json 中添加此行解决了我的问题.

非常感谢 Paul Samsotha 向我展示了解决方案。
