問題描述

定義了兩個中間件:

• DesensitizeMiddleware 響應(yīng)數(shù)據(jù)注解脫敏中間件
• ResponseCaseConverter 響應(yīng)數(shù)據(jù)下劃線轉(zhuǎn)駝峰

現(xiàn)出現(xiàn)一個問題：當(dāng)我定一個字段id_card，數(shù)據(jù)脫敏并將字段名變成idCard,這個時候，就不能脫敏成功，需將ResponseCaseConverter移除掉，才能正常響應(yīng)脫敏

中間件配置：

<?php

return [
    '@' => [
        \Landao\WebmanCore\Middleware\DesensitizeMiddleware::class,
        \Landao\WebmanCore\Middleware\ResponseCaseConverter::class
    ]
];

DesensitizeMiddleware代碼：

<?php

namespace Landao\WebmanCore\Middleware;

use Landao\WebmanCore\Helpers\DesensitizeHelper;
use Landao\WebmanCore\ParseAnnotation\DesensitizeParse;
use Webman\Http\Request;
use Webman\Http\Response;
use Webman\MiddlewareInterface;

/**
 * 注解脫敏中間件
 */
class DesensitizeMiddleware implements MiddlewareInterface
{
    /**
     * 響應(yīng)數(shù)據(jù)的根路徑
     * @var string
     */
    protected $rootPath = 'data';

    public function process(Request $request, callable $handler): Response
    {
        // 先執(zhí)行后續(xù)中間件和控制器，獲取響應(yīng)
        $response = $handler($request);

        // 獲取當(dāng)前控制器和方法
        $controller = $request->controller;
        $action = $request->action;

        // 獲取脫敏規(guī)則
        $desensitizeRules = DesensitizeParse::getDesensitizeRules($controller, $action);
        if (empty($desensitizeRules)) {
            return $response;
        }

        // 嘗試解析響應(yīng)內(nèi)容
        $content = $response->rawBody();
        $data = json_decode($content, true);
        if (json_last_error() !== JSON_ERROR_NONE) {
            return $response;
        }
        // 支持根路徑配置（如API響應(yīng)格式為 {code:200, data:{...}}）
        $targetData = &$data;
        if (!empty($this->rootPath)) {
            $rootFields = explode('.', $this->rootPath);
            foreach ($rootFields as $field) {
                if (!isset($targetData[$field])) {
                    // 根路徑不存在，記錄日志并返回原始響應(yīng)
                    return $response;
                }
                $targetData = &$targetData[$field];
            }
        }
        // 應(yīng)用脫敏規(guī)則
        if (is_array($targetData)) {
            // 根數(shù)據(jù)是數(shù)組，遍歷每個元素處理
            foreach ($targetData as &$item) {
                if (is_array($item)) {
                    $this->processArrayItem($item, $desensitizeRules);
                }
            }
        } else {
            // 根數(shù)據(jù)是對象，直接處理
            foreach ($desensitizeRules as $rule) {
                $this->applyDesensitize($targetData, $rule['field'], $rule['rule']);
            }
        }

        $response->withBody(json_encode($data, JSON_UNESCAPED_UNICODE));
        // 更新響應(yīng)內(nèi)容
        return $response;
    }
}

ResponseCaseConverter代碼：

<?php

namespace Landao\WebmanCore\Middleware;

use Landao\WebmanCore\Helpers\CamelHelper;
use Webman\Http\Request;
use Webman\Http\Response;
use Webman\Middleware;

/**
 * 響應(yīng)數(shù)據(jù)下劃線轉(zhuǎn)駝峰
 */
class ResponseCaseConverter extends Middleware
{
    public function process(Request $request, callable $handler): Response
    {
        // 先執(zhí)行后續(xù)中間件獲取響應(yīng)
        $response = $handler($request);

        // 只處理JSON響應(yīng)
        $contentType = $response->getHeader('Content-Type');
        if (strpos($contentType, 'application/json') !== false) {
            $body = $response->rawBody();
            $data = json_decode($body, true);

            // 檢查JSON解碼是否成功
            if (json_last_error() === JSON_ERROR_NONE && is_array($data)) {
                // 使用CamelHelper轉(zhuǎn)換鍵名
                $convertedData = CamelHelper::recursiveConvertNameCaseToCamel($data);

                // 更新響應(yīng)內(nèi)容
                $newBody = json_encode($convertedData, JSON_UNESCAPED_UNICODE | JSON_PRETTY_PRINT);
                $response = $response->withBody($newBody);
            }
        }
        return $response;
    }
}

是中間件順序配置錯了嗎？或者有沒有更好的不侵入代碼，去處理這兩個業(yè)務(wù)？
