## 前言
|
||
|
||
LongPort OpenAPI SDK 基於 Rust 底層提供標準實現，目前我們已經發布了 Python, Node.js, Rust 和 C++ SDK，其他語言的支持後面會陸續推出。
|
||
|
||
## API Host
|
||
|
||
- HTTP API - `https://openapi.longportapp.com`
|
||
- WebSocket Quote - `wss://openapi-quote.longportapp.com`
|
||
- Webssocket Trade - `wss://openapi-trade.longportapp.com`
|
||
|
||
:::tip
|
||
中國大陸地區訪問，建議採用 `openapi.longportapp.cn`, `openapi-quote.longportapp.cn`, `openapi-trade.longportapp.cn` 以提升訪問速度。

|

|
||
下面我們以獲取資產為例，演示一下如何使用 SDK。
|
||
|
||
## 配置開發者賬戶
|
||
|
||
1. 下載 [LongPort](https://longportapp.com/download) 並完成開戶。
|
||
2. 完成 Python 3 環境安裝，並安裝 Pip
|
||
3. 從 [LongPort OpenAPI](https://open.longportapp.com) 官網獲取 ` App Key`, `App Secret`, `Access Token` 等信息。
|
||
|
||
**_獲取 App Key, App Secret, Access Token 等信息_**
|
||
|
||
訪問 [LongPort OpenAPI](https://open.longportapp.com) 網站，登錄後，進入“個人中心”。
|
||
|
||
在頁面上會給出“應用憑證”憑證信息，我們拿到以後設置環境變量，便於後面開發使用方便。
|
||
|
||
### macOS / Linux 環境下設置環境變量
|
||
|
||
打開終端，輸入下面的命令即可：
|
||
|
||
```bash
|
||
$ export LONGBRIDGE_APP_KEY="從頁面上獲取到的 App Key"
|
||
$ export LONGBRIDGE_APP_SECRET="從頁面上獲取到的 App Secret"
|
||
$ export LONGBRIDGE_ACCESS_TOKEN="從頁面上獲取到的 Access Token"
|
||
```
|
||
|
||
### Windows 下設置環境變量
|
||
|
||
Windows 要稍微複雜一些，按下 `Win + R` 快捷鍵，輸入 `cmd` 命令啟動命令行（建議使用 [Windows Terminal](https://apps.microsoft.com/store/detail/windows-terminal/9N0DX20HK701) 獲得更好的開發體驗）。
|
||
|
||
在命令行里面輸入下面的命令設置環境變量：
|
||
|
||
```bash
|
||
C:\Users\jason> setx LONGBRIDGE_APP_KEY "從頁面上獲取到的 App Key"
|
||
成功：指定的值已得到保存。
|
||
|
||
C:\Users\jason> setx LONGBRIDGE_APP_SECRET "從頁面上獲取到的 App Secret"
|
||
成功：指定的值已得到保存。
|
||
|
||
C:\Users\jason> setx LONGBRIDGE_ACCESS_TOKEN "從頁面上獲取到的 Access Token"
|
||
成功：指定的值已得到保存。
|
||
```
|
||
|
||
:::caution
|
||
|
||
Windows 環境變量限制，當上面 3 條命令執行成功以後，你需要重新啟動 Windows 或者註銷後重新登錄一次，才可以讀取到。
|
||
|
||
:::
|
||
|
||
註銷或重新啟動後，再次打開命令行，輸入下面的命令驗證一下環境變量是否設置正確：
|
||
|
||
```bash
|
||
C:\Users\jason> set LONGBRIDGE
|
||
LONGBRIDGE_APP_KEY=xxxxxxx
|
||
LONGBRIDGE_APP_SECRET=xxxxxx
|
||
LONGBRIDGE_ACCESS_TOKEN=xxxxxxx
|
||
```
|
||
|
||
如果能正確打印你剛才設置的值，那麼環境變量就是對了。
|
||
|
||
:::tip
|
||
建議您設置好 `LONGBRIDGE_APP_KEY`, `LONGBRIDGE_APP_SECRET`, `LONGBRIDGE_ACCESS_TOKEN` 這幾個環境變量。我們為了演示方便，後面各章節文檔中的示例代碼都會使用這幾個環境變量。
|
||
|
||
如您在 Windows 環境不方便使用環境變量，可根據個人需要，修改代碼。
|
||
:::
|
||
|
||
:::caution
|
||
請注意保護好您的 **Access Token** 信息，任何人獲得到它，都可以通過 OpenAPI 來交易你的賬戶！

### 訂閱實時行情
|
||
|
||
訂閱行情數據請檢查 [開發者中心](https://open.longportapp.com/account) - “行情權限”是否正確
|
||
|
||
- 港股 - BMP 基礎報價，無實時行情推送，無法用 WebSocket 訂閱
|
||
- 美股 - LV1 納斯達克最優報價 (只限 Open API）
|
||
|
||
運行前訪問 [開發者中心](https://open.longportapp.com/account)，檢查確保賬戶有正確的行情權限。
|
||
|
||
:::info
|
||
|
||
如沒有開通行情權限，可以通過“LongPort”手機客戶端，並進入“我的 - 我的行情 - 行情商城”購買開通行情權限。

下面我們做一次 [委託下單](https://open.longportapp.com/docs/trade/order/submit) 動作，我們假設要以 50 HKD 買入 `700.HK` 的數量為 `100`。
|
||
|
||
> NOTE: 為了防止測試買入成功，這裡演示給了一個較低的價格，避免成交。OpenAPI 操作均等同與線上交易，請謹慎操作，開發調試注意參數細節。
