+# C语言日志库logging
+
+## 简介
+
+logging是一个轻量级的简单易用C语言日志库，支持日志级别、日志格式、日志输出、日志文件等功能。
+
+## 功能
+
+- 支持日志级别：DEBUG、INFO、WARN、ERROR、FATAL
+- 支持日志格式：时间戳、日志级别、日志内容
+- 支持日志输出：控制台、文件
+- 支持日志文件：自动创建、自动滚动、自动删除(未完成)
+
+## 使用方法
+
+### 控制台日志
+```c
+#include "logging.h"
+
+int main() {
+    Logging *log = createLogging(); // 创建日志对象
+
+    Logger *logger = log->getLogger("testLogger",LOG_DEBUG); //获取日志控制器
+
+    logger->addHandler(consoleHandler("test")); //为日志对象添加控制台处理器
+
+    logger->info("This is an info message");
+    logger->error("你好,这是一个错误消息%s", "123");
+    logger->fatal("This is an fatal message");
+    logger->debug("This is a debug message");
+    logger->warning("This is a warning message%s", "123");
+
+    destroyLogging(log);
+    return 0;
+}
+```
+
+### 文件日志
+```c
+#include "logging.h"
+
+int main() {
+    // Your code goes here
+    Logging *log = createLogging();
+    Logger *logger = log->getLogger("testLogger",LOG_DEBUG);
+    
+    logger->addHandler(consoleHandler("test"));   //为日志对象添加文件处理器
+
+    logger->info("This is an info message");
+    logger->error("你好,这是一个错误消息%s", "123");
+    logger->fatal("This is an fatal message");
+    logger->debug("This is a debug message");
+    logger->warning("This is a warning message%s", "123");
+
+    destroyLogging(log);
+    return 0;
+}
+```
+
+### 日志拦截器
+> 支持添加自定义的拦截器， 目前内置了子串拦截器
+
+> 拦截器的作用:可以将拦截到的日志重定向到拦截器的专属处理器中
+
+
+#### 例子
+将拦截到的日志重定向到专属文件处理器中
+```c
+#include "logging.h"
+
+
+int main() {
+    Logging *log = createLogging();
+    Logger *logger = log->getLogger("testLogger",LOG_DEBUG);
+    logger->addHandler(consoleHandler("test"));
+
+    logger->info("This is an info message");
+    logger->error("你好,这是一个错误消息%s", "123");
+    logger->fatal("This is an fatal message");
+    logger->debug("This is a debug message");
+    logger->warning("This is a warning message%s", "123");
+
+    char *test1[] = {"123", "你好"};//要拦截的字符串
+    //添加拦截器，将拦截到的日志重定向到拦截器的专属处理器中
+    log_Interceptor * tint = substringInterceptor(test1,2,LOG_DEBUG,fileHandler("被拦截")); 
+    logger->addInterceptor(tint);
+    printf("Interceptor added\n");
+
+    logger->info("This is an info message");
+    logger->error("你好,这是一个错误消息%s", "123");
+    logger->fatal("This is an fatal message");
+
+    logger->debug("This is a debug message");
+    logger->warning("This is a warning message%s", "123");
+
+    destroyLogging(log);
+    return 0;
+}
+```
