【问题】
折腾:
期间,去运行代码:
package main import ( "fmt" "log" "os" //"io/ioutil" //"net/http" "runtime" "path" "strings" ) // GetCurFilename // Get current file name, without suffix func GetCurFilename() string { _, fulleFilename, _, _ := runtime.Caller(0) //fmt.Println(fulleFilename) var filenameWithSuffix string filenameWithSuffix = path.Base(fulleFilename) //fmt.Println("filenameWithSuffix=", filenameWithSuffix) var fileSuffix string fileSuffix = path.Ext(filenameWithSuffix) //fmt.Println("fileSuffix=", fileSuffix) var filenameOnly string filenameOnly = strings.TrimSuffix(filenameWithSuffix, fileSuffix) //fmt.Println("filenameOnly=", filenameOnly) return filenameOnly } //get url response html func GetUrlRespHtml(url string) string{ var respHtml string = ""; resp, err := http.Get(url) if err != nil { fmt.Printf("http get response errror=%s\n", err) } defer resp.Body.Close() body, err := ioutil.ReadAll(resp.Body) //fmt.Printf("body=%s\n", body) respHtml = body return respHtml } func main() { fmt.Printf("this is EmulateLoginBaidu.go\n") var filenameOnly string filenameOnly = GetCurFilename() fmt.Println("filenameOnly=", filenameOnly) var logFilename string = filenameOnly + ".log"; fmt.Println("logFilename=", logFilename) //logfile,err: = os.OpenFile("/Users/cybercare/tmp/test.log",os.O_RDWR|os.O_CREATE,0666) //logFile, err: = os.OpenFile(logFilename, os.O_RDWR | os.O_CREATE, 0777) //logFile, err: = os.OpenFile(logFilename, os.O_RDWR | os.O_CREATE, 0777); logFile, err := os.OpenFile(logFilename, os.O_RDWR | os.O_CREATE, 0777) if err != nil { fmt.Printf("open file error=%s\r\n", err.Error()) os.Exit(-1) } defer logFile.Close() //logger:=log.New(logFile,"\r\n", log.Ldate | log.Ltime | log.Llongfile) logger:=log.New(logFile,"\r\n", log.Ldate | log.Ltime | log.Lshortfile) logger.Println("normal log 1") logger.Println("normal log 2") //【已解决】go代码出错退出:exit status 1 //https://www.crifan.org/go_language_can_printf_info_and_exit_status_1/ //logger.Panic("panic 1") //logger.Fatal("fatal 1") var baiduMainUrl string baiduMainUrl = "http://www.baidu.com/"; //baiduMainUrl := "http://www.baidu.com/"; //var baiduMainUrl string = "http://www.baidu.com/"; fmt.Printf("baiduMainUrl=%s", baiduMainUrl) respHtml := GetUrlRespHtml(baiduMainUrl) logger.Printf("respHtml=%s", respHtml) }
结果出错:
D:\tmp\tmp_dev_root\go\src\github.com\user\EmulateLoginBaidu>go run EmulateLoginBaidu.go # command-line-arguments .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence a1 be .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence d2 d1 .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence bd e2 .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence be f6 .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence a1 bf .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence b4 fa .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence c2 eb .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence b3 f6 .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence b4 ed .\EmulateLoginBaidu.go:73: illegal UTF-8 sequence .\EmulateLoginBaidu.go:73: too many errors D:\tmp\tmp_dev_root\go\src\github.com\user\EmulateLoginBaidu>
如图:
即:
illegal UTF-8 sequence |
【解决过程】
1.很明显,是字符编码问题。
2.去看了看当前的文件,果然是GBK的:
所以,去改为UTF-8:
然后再去重新编译代码,果然就可以了。
至少没有这个utf-8的错误提示了。
【总结】
go代码的文件编码中,如果包含非英文字符,比如此处的中文,如果go文件本身是非UTF-8编码,即使是放在注释里面,也是不行的。
必须要确保go文件本身是UTF-8编码的才可以的。
注:
Notepad++可以实现文件编码转换,不熟悉的可以参考:
