# C语言日志库logging
|
||
|
||
[English](README.en.md)
|
||
|
||
## 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、日志分割
|
||
|
||
## 安装
|
||
- conan安装使用
|
||
```shell
|
||
conan create .
|
||
```
|
||
- cmake安装使用
|
||
```shell
|
||
```
|
||
|
||
## 使用方法
|
||
|
||
|
||
|
||
### 控制台日志
|
||
```c
|
||
#include "logging.h"
|
||
|
||
int main() {
|
||
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
|
||
|
||
log_info("This is an info message");
|
||
log_error("This is an error message%s", "123");
|
||
log_fatal("This is an fatal message");
|
||
log_debug("This is a debug message");
|
||
log_warning("This is a warning message%s", "123");
|
||
|
||
destroyDefaultLogger();
|
||
return 0;
|
||
}
|
||
```
|
||
|
||
### 文件日志
|
||
```c
|
||
#include "logging.h"
|
||
#include "logging/logging-handler.h"
|
||
|
||
int main() {
|
||
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
|
||
logger->addHandler(loggingFileHandler("test1", 1024*1024));
|
||
|
||
log_info("This is an info message");
|
||
log_error("This is an error message%s", "123");
|
||
log_fatal("This is an fatal message");
|
||
log_debug("This is a debug message");
|
||
log_warning("This is a warning message%s", "123");
|
||
|
||
destroyDefaultLogger();
|
||
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
|
||
|
||
|
||
#### 单个子串拦截器
|
||
将拦截到的日志重定向到专属文件处理器中
|
||
```c
|
||
#include "logging.h"
|
||
#include <stdio.h>
|
||
|
||
int main() {
|
||
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
|
||
|
||
log_info("This is an info message");
|
||
log_error("This is an error message%s", "123");
|
||
log_fatal("This is an fatal message");
|
||
log_debug("This is a debug message");
|
||
log_warning("This is a warning message%s", "123");
|
||
|
||
char *test1[] = {"123", "tt", NULL};
|
||
|
||
log_Interceptor *tint = loggingSubStringInterceptor(
|
||
test1,
|
||
LOG_DEBUG,
|
||
loggingFileHandler("test_interceptor", 1024 * 1024),
|
||
true);
|
||
|
||
logger->addInterceptor(tint);
|
||
|
||
printf("\n");
|
||
printf("Interceptor added\n");
|
||
printf("\n");
|
||
|
||
log_info("This is an info message");
|
||
log_error("This is an error message%s", "123");
|
||
log_fatal("This is an fatal message");
|
||
log_debug("This is a debug message");
|
||
log_warning("This is a warning message%s", "123");
|
||
|
||
destroyDefaultLogger();
|
||
return 0;
|
||
}
|
||
```
|
||
|
||
#### 多个子串拦截器
|
||
```c
|
||
#include "logging.h"
|
||
#include <stdbool.h>
|
||
#include <stdio.h>
|
||
#include <time.h>
|
||
|
||
int main() {
|
||
Logger *logger = newDefaultLogger("testLogger", LOG_DEBUG);
|
||
|
||
log_info("This is an info message");
|
||
log_error("This is an error message%s", "123");
|
||
log_fatal("This is an fatal message");
|
||
log_debug("This is a debug message");
|
||
log_warning("This is a warning message%s", "123");
|
||
|
||
char *test1[] = {"This",NULL};
|
||
|
||
log_Interceptor *tint = loggingSubStringInterceptor(
|
||
test1,
|
||
LOG_DEBUG,
|
||
loggingFileHandler("test_interceptor", 1024 * 1024),
|
||
false);
|
||
|
||
logger->addInterceptor(tint);
|
||
|
||
char *test2[] = {"123",NULL};
|
||
|
||
log_Interceptor *tint1 = loggingSubStringInterceptor(
|
||
test2,
|
||
LOG_DEBUG,
|
||
loggingFileHandler("test_interceptor1", 1024 * 1024),
|
||
true);
|
||
|
||
logger->addInterceptor(tint1);
|
||
|
||
printf("\n");
|
||
printf("Interceptor added\n");
|
||
printf("\n");
|
||
|
||
log_info("This is an info message");
|
||
log_error("This is an error message%s", "123");
|
||
log_fatal("This is an fatal message");
|
||
log_debug("This is a debug message");
|
||
log_warning("This is a warning message%s", "123");
|
||
|
||
destroyDefaultLogger();
|
||
return 0;
|
||
}
|
||
```
