## Architecture

### Core Components

- **`org.codelibs.curl.Curl`**: Static entry point providing factory methods for all HTTP methods (GET, POST, PUT, DELETE, HEAD, OPTIONS, CONNECT, TRACE)
- **`org.codelibs.curl.CurlRequest`**: Fluent request builder supporting parameters, headers, body content, SSL config, proxies, timeouts, and caching

        }
        // ensure file is open
        try (SmbFileHandleImpl fd = ensureOpen(); SmbTreeHandleImpl th = fd.getTree()) {

            if (log.isTraceEnabled()) {
                log.trace("read: fid=" + fd + ",off=" + off + ",len=" + len);
            }

            final int type = this.file.getType();
            int r, n;

        }

        // Perform cleanup and health checks without global synchronization
        cleanup();
        performHealthCheck();

        if (log.isTraceEnabled()) {
            log.trace("Exclusive " + nonPooled + " enforced signing " + forceSigning);
        }

        // Check for existing connection
        if (!nonPooled && tc.getConfig().getSessionLimit() != 1) {

在建置 API 時，「路徑」是分離「關注點」和「資源」的主要方式。

#### 操作

這裡的「操作」指的是 HTTP 的「方法」之一。

其中包括：

* `POST`
* `GET`
* `PUT`
* `DELETE`

……以及更少見的：

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

在 HTTP 協定中，你可以使用這些「方法」之一（或更多）與每個路徑進行通信。

---

在建置 API 時，你通常使用這些特定的 HTTP 方法來執行特定的動作。

通常你使用：

* `POST`：用來建立資料。
* `GET`：用來讀取資料。
* `PUT`：用來更新資料。
* `DELETE`：用來刪除資料。
