php利用redis实现接口数据缓存 php利用redis实现服务端数据缓存。 要求php版本大于8.0 缓存类 文件RedisCache.php <?php /** * 请求缓存类 * 利用redis实现数据缓存 * * 作者：KongHen02 * */ class RedisCache { private string $key; private Redis $redis; public function __construct(int $db = 0, bool $device = false) { $config = [ 'host' => '127.0.0.1', 'port' => 6379, 'timeout' => 2, 'database' => $db ]; try { $this->redis = new Redis(); $this->redis->connect( $config['host'], $config['port'], $config['timeout'] ); $this->redis->select($config['database']); } catch (RedisException $e) { error_log("Redis连接失败: " . $e->getMessage()); throw new RuntimeException("缓存服务不可用"); } $this->key = $this->generateKey($device); } public function getCache(): mixed { try { header('X-Cache: ' .

UTS封装uni.request请求拦截器 UTS封装请求拦截器主要就是数据类型的问题 简单封装示例：每次请求在请求头中携带设备信息 /** * 封装请求体携带设备信息 * 说明：header携带设备信息 * * 作者：KongHen02 */ export type RequestParams = { url: string; method: RequestMethod; data?: string; header?: UTSJSONObject; timeout?: number; sslVerify?: boolean; withCredentials?: boolean; firstIpv4?: boolean; } export type RequestRoot = { code: number; msg: string; data?: any } export type RequestRes = { data?: any; error?: string; } // 获取系统信息 export const getSystemInfo = (): string => { const system = uni.getSystemInfoSync() // 返回app信息，依次为appid，系统名称，系统版本，app版本，设备id，使用____分割 return system.appId + "____" + system.osName + "____" + system.osVersion + "____" + system.appVersionCode + "____" + system.deviceId } // 发送请求并携带设备信息 export const sendRequest = (options: RequestParams): Promise<RequestRes> => { let info = getSystemInfo(); let header = {} if (options.header != null) { header = UTSJSONObject.assign(options.header as UTSJSONObject, { app: info }) }else { header = UTSJSONObject.assign(header, { app: info }) } // 返回一个Promise return new Promise((resolve, reject) => { uni.request<RequestRoot>({ // ...options, // 展开其他请求配置 url: options.url, method: options.method, data: options.data ?? "", header: header, timeout: options.timeout ?? 6000, sslVerify: options.sslVerify ?? true, withCredentials: options.withCredentials ?? false, firstIpv4: options.firstIpv4 ?? false, success: (res) => { const data = res.data as RequestRoot if(data.code == 200) { // 在请求成功时解析Promise resolve({ data: data.data } as RequestRes) }else { uni.showToast({ title: data.msg, icon: "error" }) reject({ error: data['msg'] as string } as RequestRes) } }, fail: (err) => { uni.showToast({ title: err.errMsg, icon: "error" }) // 在请求失败时拒绝Promise reject({ error: err.errMsg as string } as RequestRes) } } as RequestOptions<any>); }); } 使用示例 // 导入封装的函数 import { sendRequest } from "@/common/request.uts" // 定义存储的变量 // 1. 数组 const list = ref<UTSJSONObject[]>([]) // 2. 对象 // const list = ref<UTSJSONObject>({}) // 请求示例：使用Promise的方式调用sendRequest函数 sendRequest({ url: 'https://api.example.com/data', method: 'GET' }).then(res => { // 处理请求成功的结果 list.value = res.data as UTSJSONObject[] // 数组，对应的存储数组的变量 // list.value = res.data as UTSJSONObject // 对象，对应的存储对象的变量 console.log('处理结果:', data.value); }).catch(err => { // 处理请求失败的情况 console.error('请求失败:', err); }) 在模板中使用示例 注意使用变量中数据的方法只能为下标[""]方法，.操作符不可以，会报错 <view v-for="item in noticeList" :key="item['id']"> <image mode="widthFix" :src="item['image']"></image> <view> <text>{{ item['title'] }}</text> <text>{{ item['sort'] }}</text> </view> </view>说明： 因为书写习惯原因，我自己的所有后端返回数据均为json，返回对象参数如下 参数描述示例code错误码200: 成功, 400: 失败, 或其他msg请求结果说明请求成功/请求失败等data请求返回的结果json数组/对象示例如下： data为数组 { code: 200, msg: "请求成功", data: [] } data为对象 { code: 200, msg: "请求成功", data: {} } 对应封装的请求中的自定义类型RootRes(request.uts文件中)
