中间件响应两种特定类型的 HTTP 请求...

### CORS 预检请求 { #cors-preflight-requests }

这是些带有 `Origin` 和 `Access-Control-Request-Method` 请求头的 `OPTIONS` 请求。

在这种情况下，中间件将拦截传入的请求并进行响应，出于提供信息的目的返回一个使用了适当的 CORS headers 的 `200` 或 `400` 响应。

### 简单请求 { #simple-requests }

任何带有 `Origin` 请求头的请求。在这种情况下，中间件将像平常一样传递请求，但是在响应中包含适当的 CORS headers。

## 更多信息 { #more-info }

        final String origin = httpRequest.getHeader("Origin");
        if (StringUtil.isNotBlank(origin)) {
            if (logger.isDebugEnabled()) {
                logger.debug("HTTP Request: method={}", httpRequest.getMethod());
            }
            final CorsHandlerFactory factory = ComponentUtil.getCorsHandlerFactory();
            final CorsHandler handler = factory.get(origin);
            if (handler != null) {

            List<String> originHeaders = responseHeaders.get("Access-Control-Allow-Origin");
            assertNotNull(originHeaders, "Headers should be set for origin: " + origin);
            assertTrue(originHeaders.contains(origin));
        }
    }

    // Test process method with wildcard origin
    @Test
    public void test_processWithWildcardOrigin() {
        String wildcardOrigin = "*";

            if (url.origin === window.location.origin
                && url.pathname === window.location.pathname
                && url.search === window.location.search) return;
            if (!a.hasAttribute("target")) {
                a.setAttribute("target", "_blank");
                a.setAttribute("rel", "noopener");
            }
            if (url.origin !== siteOrigin) {

          git reset origin/master --hard

          ./gradlew wrapper --gradle-version=nightly
          ./gradlew wrapper

          if ! git diff --quiet; then
            ./gradlew -v
            VERSION=$(./gradlew -v | grep "Gradle" | cut -d' ' -f2)
            git add .
            git commit -m "Update Gradle wrapper to $VERSION"
            git push --force origin devprod/upgrade-to-latest-wrapper

# CORS (Cross-Origin Resource Sharing) { #cors-cross-origin-resource-sharing }

[CORSまたは「Cross-Origin Resource Sharing」](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS) は、ブラウザで実行されているフロントエンドにバックエンドと通信するJavaScriptコードがあり、そのバックエンドがフロントエンドとは異なる「オリジン」にある状況を指します。

## オリジン { #origin }

オリジンはプロトコル (`http`、`https`) とドメイン (`myapp.com`、`localhost`、`localhost.tiangolo.com`) とポート (`80`、`443`、`8080`) の組み合わせです。

したがって、以下はすべて異なるオリジンです:

* `http://localhost`

# CORS (교차-출처 리소스 공유) { #cors-cross-origin-resource-sharing }

[CORS 또는 "Cross-Origin Resource Sharing"](https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS)란, 브라우저에서 실행되는 프론트엔드에 백엔드와 통신하는 JavaScript 코드가 있고, 백엔드가 프론트엔드와 다른 "출처(origin)"에 있는 상황을 의미합니다.

## 출처 { #origin }

출처란 프로토콜(`http`, `https`), 도메인(`myapp.com`, `localhost`, `localhost.tiangolo.com`), 그리고 포트(`80`, `443`, `8080`)의 조합을 의미합니다.

따라서, 아래는 모두 상이한 출처입니다:

* `http://localhost`

  @Nullable V removeSuccessor(N node);

  /**
   * Add {@code node} as a predecessor to the origin node. In the case of an undirected graph, it
   * also becomes a successor. Associates {@code value} with the edge connecting the two nodes.
   */
  void addPredecessor(N node, V value);

  /**
   * Add {@code node} as a successor to the origin node. In the case of an undirected graph, it also

     *     service is the origin of the stream. When zero, the origin is specified in the `origin`
     *     parameter.
     * @param origin when present, the [origin](http://tools.ietf.org/html/rfc6454) is typically
     *     represented as a combination of scheme, host and port. When empty, the origin is that of
     *     the `streamId`.
