??工作中遇到這樣一個(gè)場(chǎng)景：遠(yuǎn)程調(diào)用某個(gè)接口，該接口需要用戶的 Cookie 信息進(jìn)行權(quán)限認(rèn)證，認(rèn)證通過之后才可以打通并返回?cái)?shù)據(jù)。

在后端拿到 httpServletRequest 后，調(diào)用 getCookies() 方法，返回的是一個(gè) Cookie 類型的數(shù)組。Debug 過程中拿到的 cookie 數(shù)據(jù)結(jié)構(gòu)如下所示：

因此，需要將數(shù)組格式轉(zhuǎn)換為字符串形式，核心代碼如下：

private String getCookies(HttpServletRequest request) {
        try {
            Cookie[] cookies = request.getCookies();
            // 將Cookie對(duì)象數(shù)組轉(zhuǎn)換成字符串形式的Cookie
            if (!CoreTool.isEmpty(cookies)) {
            	// 使用數(shù)組流處理
                return  Arrays.stream(cookies)
                        .map(cookie -> cookie.getName() + "=" + cookie.getValue())
                        .collect(Collectors.joining("; "));
            }
        } catch (Exception e) {
            LOGGER.error("獲取cookie異常", e);
        }
        return "";
}

類型轉(zhuǎn)換后返回一個(gè)字符串格式的 cookie，其內(nèi)容和在網(wǎng)頁(yè)端看到的 cookie 內(nèi)容一致，處理后的 cookie 具體內(nèi)容以及截圖如下：
