Golang 在运行 main.go 时不断崩溃，异常 0xc0000005

Question

我是 Golang 的新手，并且使用 GIN 和 gorm 开发了一个基本的 REST API。 API 工作正常，代码中没有错误。 main.go 文件如下:

package main
import (
    "fmt"
    "os"

    "github.com/gin-gonic/gin"
    "github.com/joho/godotenv"
    "github.com/usman2661/Todo-Crud-Go/controllers"
    "github.com/usman2661/Todo-Crud-Go/models"

    // "github.com/gin-contrib/cors"
    "net/http"
)

func GoDotEnvVariable(key string) string {

    // load .env file
    err := godotenv.Load(".env")

    if err != nil {
        fmt.Println("Error loading .env file")
    }

    return os.Getenv(key)
}

// CORS Middleware
func CORS(c *gin.Context) {

    // First, we add the headers with need to enable CORS
    // Make sure to adjust these headers to your needs
    c.Header("Access-Control-Allow-Origin", "http://localhost:4200")
    c.Header("Access-Control-Allow-Methods", "*")
    c.Header("Access-Control-Allow-Headers", "*")
    c.Header("Content-Type", "application/json")

    // Second, we handle the OPTIONS problem
    if c.Request.Method != "OPTIONS" {

        c.Next()

    } else {

        // Everytime we receive an OPTIONS request,
        // we just return an HTTP 200 Status Code
        // Like this, Angular can now do the real
        // request using any other method than OPTIONS
        c.AbortWithStatus(http.StatusOK)
    }
}

func main() {

    router := gin.Default()

    host := GoDotEnvVariable("host")
    port := GoDotEnvVariable("dbport")
    user := GoDotEnvVariable("user")
    dbname := GoDotEnvVariable("dbname")
    password := GoDotEnvVariable("password")
    sslmode := GoDotEnvVariable("sslmode")

    models.ConnectDataBase(host, port, user, dbname, password, sslmode)

    router.Use(CORS)

    router.GET("/todos", controllers.GetTodos)          //  Get all the todos
    router.POST("/todos", controllers.CreateTodo)       // Create a new todo
    router.GET("/todos/:id", controllers.GetTodo)       // Fetch a single todo using id
    router.PUT("/todos/:id", controllers.UpdateTodo)    // Update and existing todo id has to be passed
    router.DELETE("/todos/:id", controllers.DeleteTodo) // Delete a todo using the id

    router.GET("/catagory/:username", controllers.GetCatagories) //  Get the Different catagories

    router.Run()
}

但是，有时它在运行时不断崩溃，之后它就永远无法工作了，我必须重新启动我的机器来修复它，然后它才能工作。它抛出以下异常

Exception 0xc0000005 0x0 0x7fff91b70fff 0x1a34e3f0000
PC=0x1a34e3f0000

runtime: unknown pc 0x1a34e3f0000

我在网上进行了很多研究，但找不到解决此问题的答案。是否有任何解决方案可以永久解决此问题，而不是重新启动 PC。
完全异常(exception):

Answer 1

这看起来像一个 goroutine 死锁。
在死锁的情况下，程序中运行的所有 goroutine 都将退出并产生一个堆栈跟踪，就像你看到的那样。
该程序将被 go 运行时终止。即使您的 http 服务器可能具有恢复功能，也无法从死锁中恢复。
