Mastering GoFrame Logging: From Zero to Hero

GoFrame Efficient Logging System Guide: From Beginner to Mastery

Summary

GoFrame provides a powerful, easy to configure and highly flexible logging system. Covering everything from basic logging to advanced features like log rotation, custom formats, and log sharding, this guide is perfect for Go developers who want to implement robust logging in their applications!

Why should you pay attention to the GoFrame logging system?

Ever struggled with disorganized logs or spent hours debugging because you couldn’t find the right log entry? GoFrame’s logging module will help you! Whether you're building a small service or a large application, proper logging is crucial. Let’s take a deeper look at how GoFrame makes logging both powerful and easy.

This guide covers:

  • Basic log settings and usage
  • Log levels and their importance
  • Log rotation (because no one likes huge log files!)
  • Custom formatting for better readability
  • Advanced technologies such as log sharding
  • Practical examples you can use immediately

Basic Settings

Let’s start with the basics. GoFrame's logging module (glog) provides several easy-to-use functions you'll love:

import "github.com/gogf/gf/v2/os/glog"

func main() {
    // 簡單日志記錄
    glog.Debug("調(diào)試信息")  // 用于開發(fā)人員
    glog.Info("信息")    // 一般信息
    glog.Warn("警告!")        // 注意!
    glog.Error("錯誤!")         // 出現(xiàn)問題
    glog.Fatal("嚴重錯誤!")     // 出現(xiàn)嚴重問題
}

Pro Tip: Start with Info level in production and use Debug level in development. You'll thank me later!

Intelligent log file management

One of my favorite features is automatic log rotation. No need to clean files manually! Here’s how to set it up:

import "github.com/gogf/gf/v2/os/glog"

func main() {
    l := glog.New()
    l.SetPath("./logs")                    // 日志存儲位置
    l.SetFile("app-{Ymd}.log")            // 每日輪轉(zhuǎn)!

    // 您的日志現(xiàn)在將按日期組織
    l.Info("這將寫入今天的日志文件")
}

The {Ymd} pattern in the file name means you will get the following file:

  • app-20241124.log
  • app-20241125.log
  • Wait...

Log level: Choose your level of detail

Think of the log level as a volume knob for your logs. Here's how to use them effectively:

import "github.com/gogf/gf/v2/os/glog"

func main() {
    ctx := gctx.New()
    l := glog.New()

    // 只顯示警告及以上級別
    l.SetLevel(glog.LEVEL_WARN)

    // 這些不會顯示
    l.Debug(ctx, "調(diào)試信息...")
    l.Info(ctx, "僅供參考...")

    // 這些將顯示
    l.Warning(ctx, "注意!")
    l.Error(ctx, "休斯頓,我們有問題!")
}

Beautify your blog

No one likes ugly logs! Here's how to make them easier to read:

import "github.com/gogf/gf/v2/os/glog"

func main() {
    ctx := gctx.New()
    l := glog.New()

    // 添加時間戳和文件信息
    l.SetFlags(glog.F_TIME_STD | glog.F_FILE_SHORT)

    // 添加自定義字段
    l.Infof(ctx, "用戶 %d 從 %s 登錄", 12345, "192.168.1.1")
}

Output:

<code>2024-11-24 14:30:00 [INFO] main.go:12: 用戶 12345 從 192.168.1.1 登錄</code>

Advanced: Log Sharding

Working on a large project? You may want to split your logs based on log type. Here’s a clever way:

import "github.com/gogf/gf/v2/os/glog"

func main() {
    ctx := gctx.New()

    // 創(chuàng)建單獨的日志記錄器
    access := glog.New()
    errors := glog.New()

    // 以不同的方式配置它們
    access.SetFile("access-{Ymd}.log")
    errors.SetFile("errors-{Ymd}.log")

    // 在適當?shù)牡胤绞褂盟鼈?    access.Info(ctx, "用戶查看了主頁")
    errors.Error(ctx, "無法連接到數(shù)據(jù)庫")
}

Custom format to meet special needs

Need your logs to be formatted in a specific way? Maybe for a log aggregation tool? Here’s how:

import (
    "fmt"
    "github.com/gogf/gf/v2/os/glog"
    "time"
)

type CustomWriter struct{}

func (w *CustomWriter) Write(p []byte) (n int, err error) {
    // 添加 JSON 格式
    log := fmt.Sprintf(`{"time":"%s","message":"%s"}`, 
        time.Now().Format(time.RFC3339),
        string(p))
    fmt.Print(log)
    return len(log), nil
}

func main() {
    l := glog.New()
    l.SetWriter(&CustomWriter{})
    l.Print("發(fā)生了一些事情!")
}

Quick Success Tips

  1. Start Small: Start with basic logging and add complexity as needed
  2. Use log levels wisely: debug for development, info for general operations, errors for problems
  3. Rotate your logs: Set up log rotation from day one - your disk space will thank you
  4. Add context: include relevant user information, such as user ID, request ID, etc.
  5. Monitor log size: Use SetFile with date mode to manage log growth

Summary

Logging may not be the most exciting part of development, but it's definitely one of the most important. With GoFrame's logging module, you have all the necessary tools at your disposal to implement a powerful logging system that will make your life easier when things go wrong (and they always do!).

Next step?

  • Try implementing these examples in your project
  • Try different log formats
  • Set up log rotation according to your needs
  • Consider adding structured logs for better analysis

Happy journaling! ?

How can you handle JSON encoding and decoding effectively in Go? How can you handle JSON encoding and decoding effectively in Go? Jun 11, 2025 am 12:02 AM

Effective handling of JSON in Go requires attention to structural labels, optional fields and dynamic analysis. Use the struct tag to customize the JSON key name, such as json:"name"; make sure the fields are exported for access by the json package. Use pointers or omitempty tags when processing optional fields to distinguish between unprovided values ??from explicit zeros. When parsing unknown JSON, map[string]interface{} can be used to extract data with type assertions. The default number will be parsed as float64. json.MarshalIndent can be used to beautify the output during debugging, but the production environment should avoid unnecessary formatting. Mastering these techniques can improve the robustness and ability of your code

How can Go programs interact with C code using Cgo? What are the trade-offs? How can Go programs interact with C code using Cgo? What are the trade-offs? Jun 10, 2025 am 12:14 AM

Go programs can indeed interact with C code through Cgo, which allows Go to call C functions directly. When using Cgo, just import the pseudo-package "C" and embed C code in the comments above the import line, such as including C function definitions and calling them. In addition, external C library can be linked by specifying link flags such as #cgoLDFLAGS. However, there are many issues to pay attention to when using Cgo: 1. Memory management needs to be processed manually and cannot rely on Go garbage collection; 2. Go types may not match C types, and types such as C.int should be used to ensure consistency; 3. Multiple goroutine calls to non-thread-safe C libraries may cause concurrency problems; 4. There is performance overhead for calling C code, and the number of calls across language boundaries should be reduced. Cgo's lack

How does Go handle pointers, and how do they differ from pointers in C/C  ? How does Go handle pointers, and how do they differ from pointers in C/C ? Jun 10, 2025 am 12:13 AM

Go simplifies the use of pointers and improves security. 1. It does not support pointer arithmetic to prevent memory errors; 2. Automatic garbage collection and management of memory without manual allocation or release; 3. The structure method can seamlessly use values ??or pointers, and the syntax is more concise; 4. Default safe pointers to reduce the risk of hanging pointers and memory leakage. These designs make Go easier to use and safer than C/C, but sacrifice some of the underlying control capabilities.

What are the implications of Go's static linking by default? What are the implications of Go's static linking by default? Jun 19, 2025 am 01:08 AM

Go compiles the program into a standalone binary by default, the main reason is static linking. 1. Simpler deployment: no additional installation of dependency libraries, can be run directly across Linux distributions; 2. Larger binary size: Including all dependencies causes file size to increase, but can be optimized through building flags or compression tools; 3. Higher predictability and security: avoid risks brought about by changes in external library versions and enhance stability; 4. Limited operation flexibility: cannot hot update of shared libraries, and recompile and deployment are required to fix dependency vulnerabilities. These features make Go suitable for CLI tools, microservices and other scenarios, but trade-offs are needed in environments where storage is restricted or relies on centralized management.

How do I create a buffered channel in Go? (e.g., make(chan int, 10)) How do I create a buffered channel in Go? (e.g., make(chan int, 10)) Jun 20, 2025 am 01:07 AM

To create a buffer channel in Go, just specify the capacity parameters in the make function. The buffer channel allows the sending operation to temporarily store data when there is no receiver, as long as the specified capacity is not exceeded. For example, ch:=make(chanint,10) creates a buffer channel that can store up to 10 integer values; unlike unbuffered channels, data will not be blocked immediately when sending, but the data will be temporarily stored in the buffer until it is taken away by the receiver; when using it, please note: 1. The capacity setting should be reasonable to avoid memory waste or frequent blocking; 2. The buffer needs to prevent memory problems from being accumulated indefinitely in the buffer; 3. The signal can be passed by the chanstruct{} type to save resources; common scenarios include controlling the number of concurrency, producer-consumer models and differentiation

How can you use Go for system programming tasks? How can you use Go for system programming tasks? Jun 19, 2025 am 01:10 AM

Go is ideal for system programming because it combines the performance of compiled languages ??such as C with the ease of use and security of modern languages. 1. In terms of file and directory operations, Go's os package supports creation, deletion, renaming and checking whether files and directories exist. Use os.ReadFile to read the entire file in one line of code, which is suitable for writing backup scripts or log processing tools; 2. In terms of process management, the exec.Command function of the os/exec package can execute external commands, capture output, set environment variables, redirect input and output flows, and control process life cycles, which are suitable for automation tools and deployment scripts; 3. In terms of network and concurrency, the net package supports TCP/UDP programming, DNS query and original sets.
