-# Kenaito Config Center C Client
-
-C 语言的配置中心客户端 SDK，适用于嵌入式设备或高性能场景，依赖 libcurl。
-
-## 依赖
-
-- libcurl
-
-### Ubuntu/Debian
-
-```bash
-apt-get install libcurl4-openssl-dev
-```
-
-### CentOS/RHEL
-
-```bash
-yum install libcurl-devel
-```
-
-> **macOS**：系统自带 libcurl，无需额外安装。
-
-## 快速开始
-
-### 1. 安装依赖
-
-#### Ubuntu/Debian
-
-```bash
-apt-get install libcurl4-openssl-dev libcjson-dev
-```
-
-#### CentOS/RHEL
-
-```bash
-yum install libcurl-devel libcjson-devel
-```
-
-#### macOS
-
-```bash
-brew install cJSON
-```
-
-> **macOS**：系统自带 libcurl，无需额外安装。
-
-### 2. 编译 SDK
-
-**macOS：**
-
-```bash
-cd kenaito-conf-c-client
-gcc -c main.c -o kenaito_conf.o -I/usr/local/opt/cjson/include -lcurl
-ar rcs libkenaito_conf.a kenaito_conf.o
-```
-
-**Ubuntu/Debian：**
-
-```bash
-cd kenaito-conf-c-client
-gcc -c main.c -o kenaito_conf.o $(pkg-config --cflags libcjson) -lcurl
-ar rcs libkenaito_conf.a kenaito_conf.o
-```
-
-### 3. 编译 Demo
-
-**macOS：**
-
-```bash
-cd kenaito-conf-c-client-demo
-gcc -o demo main.c ../kenaito-conf-c-client/main.c -I/usr/local/opt/cjson/include -lcurl -lpthread
-./demo
-```
-
-**Ubuntu/Debian：**
-
-```bash
-cd kenaito-conf-c-client-demo
-gcc -o demo main.c ../kenaito-conf-c-client/main.c $(pkg-config --cflags libcjson) -lcurl -lpthread
-./demo
-```
-
-### 4. 使用 SDK
-
-在你的项目中：
-
-```c
-#include "kenaito-conf-c-client/main.c"
-
-// 或者链接静态库
-// gcc -o myapp myapp.c -lkenaito_conf -lcurl -lcjson -lpthread
-```
-
-### 5. 完整示例
-
-```c
-#include <stdio.h>
-#include "../kenaito-conf-c-client/main.c"
-
-void on_change(const char *key, const char *value) {
-    printf("config changed: %s = %s\n", key, value);
-}
-
-int main() {
-    Config config = {
-        .baseUrl = "http://localhost:8080",
-        .appName = "my-app",
-        .env = "daily",
-        .version = "latest",
-        .token = "",
-        .syncInterval = 10,
-        .ignoreGlobal = 0,
-        .cacheDir = "."
-    };
-
-    ConfigClient client;
-    config_client_init(&client, &config);
-    client.onChange = on_change;
-
-    // 启动客户端（拉取全量配置 + 开启定时同步）
-    config_client_start(&client);
-
-    // 获取配置
-    const char *dbHost = config_client_get(&client, "database.host");
-    const char *dbPort = config_client_get(&client, "database.port");
-
-    printf("database.host = %s\n", dbHost ? dbHost : "not found");
-    printf("database.port = %s\n", dbPort ? dbPort : "not found");
-
-    // 等待配置变更
-    sleep(30);
-
-    // 停止客户端
-    config_client_stop(&client);
-    return 0;
-}
-```
-
-### 3. 配置变更监听
-
-```c
-void on_config_change(const char *key, const char *value) {
-    printf("[ConfigChange] %s = %s\n", key, value);
-    // 在此处处理配置更新逻辑
-    // 例如：重新初始化数据库连接、更新日志级别等
-}
-
-// 注册回调
-client.onChange = on_config_change;
-```
-
-## 配置参数
-
-| 参数 | 说明 | 默认值 | 必填 |
-|------|------|--------|------|
-| `baseUrl` | 配置中心地址 | - | 是 |
-| `appName` | 应用名称 | - | 是 |
-| `env` | 环境（dev/daily/prod） | `dev` | 否 |
-| `version` | 配置版本 | `latest` | 否 |
-| `token` | 认证令牌 | 空 | 否 |
-| `syncInterval` | 同步间隔（秒） | `10` | 否 |
-| `ignoreGlobal` | 是否忽略全局配置 | `0` | 否 |
-| `cacheDir` | 本地缓存目录 | `.` | 否 |
-
-## API 参考
-
-### 初始化客户端
-
-```c
-void config_client_init(ConfigClient *client, Config *config);
-```
-
-### 获取配置值
-
-```c
-const char *config_client_get(ConfigClient *client, const char *key);
-```
-
-**参数：**
-- `client`：客户端实例
-- `key`：配置键名
-
-**返回值：**
-- 成功：配置值字符串
-- 失败：`NULL`
-
-### 停止客户端
-
-```c
-void config_client_stop(ConfigClient *client);
-```
-
-**说明：** 释放 libcurl 资源，停止定时同步。
-
-### 注册变更回调
-
-```c
-client.onChange = on_config_change;
-```
-
-**回调签名：**
-```c
-void on_config_change(const char *key, const char *value);
-```
-
-## 完整示例代码
-
-```c
-#include <stdio.h>
-#include <stdlib.h>
-#include <string.h>
-#include <curl/curl.h>
-#include <time.h>
-
-// 此处引入 kenaito-conf-c-client/main.c 的完整实现
-// 或使用编译好的库文件
-
-void on_change(const char *key, const char *value) {
-    printf("[ConfigChange] %s = %s\n", key, value);
-}
-
-int main() {
-    printf("=== Kenaito Config Center C Client Demo ===\n");
-
-    Config config = {
-        .baseUrl = "http://localhost:8080",
-        .appName = "kenaito-springboot-demo",
-        .env = "daily",
-        .version = "latest",
-        .token = "",
-        .syncInterval = 10,
-        .ignoreGlobal = 0,
-        .cacheDir = "."
-    };
-
-    ConfigClient client;
-    config_client_init(&client, &config);
-    client.onChange = on_change;
-
-    // 获取配置
-    const char *value = config_client_get(&client, "database.host");
-    if (value) {
-        printf("database.host = %s\n", value);
-    } else {
-        printf("database.host not found\n");
-    }
-
-    // 等待配置变更（实际应用中应在此处运行业务逻辑）
-    printf("Listening for config changes...\n");
-    sleep(30);
-
-    config_client_stop(&client);
-    printf("Client stopped.\n");
-    return 0;
-}
-```
-
-## Demo
-
-运行示例项目：
-
-```bash
-cd kenaito-conf-c-client-demo
-gcc -o demo ../kenaito-conf-c-client/main.c -lcurl
-./demo
-```
-
-Demo 默认配置：
-- 应用名称：`kenaito-springboot-demo`
-- 环境：`daily`
-- 配置中心地址：`http://localhost:8080`
-- 同步间隔：10 秒
-
-## 注意事项
-
-1. **JSON 解析**：当前示例代码仅演示 HTTP 请求，实际使用需集成 JSON 解析库（如 cJSON）
-2. **配置缓存**：建议实现本地文件缓存，避免频繁请求配置中心
-3. **线程安全**：多线程环境下需自行添加锁机制保护配置读取
-4. **错误处理**：生产环境应完善网络异常、超时、重试等错误处理逻辑
-5. **内存管理**：使用 `config_client_stop()` 释放资源前不要访问配置
-
-## 与其他客户端对比
-
-| 特性 | C 客户端 | Go 客户端 | Java 客户端 |
-|------|---------|----------|------------|
-| 编译方式 | 手动 gcc | go build | Maven |
-| 依赖管理 | 手动链接 | go mod | Maven |
-| JSON 解析 | 需自行集成 | 标准库 | FastJSON2 |
-| 定时同步 | 需自行实现 | ✅ | ✅ |
-| 配置缓存 | 需自行实现 | ✅ | ✅ |
-| 变更回调 | ✅ | ✅ | ✅ |
-| 线程安全 | 需自行实现 | ✅ | ✅ |
-
-## 版本历史
-
-- **1.0.0** - 初始版本
-  - 基础 HTTP 拉取配置功能
-  - 配置变更回调接口
-  - 简化示例代码
-
-## 后续开发计划
-
-- [ ] 集成 cJSON 实现 JSON 解析
-- [ ] 实现定时轮询同步机制
-- [ ] 添加本地文件缓存支持
-- [ ] 完善错误处理和重试机制
-- [ ] 添加线程安全保护
