折腾：
期间，去运行代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 | package mainimport ( "fmt" "log" "os" //"io/ioutil" //"net/http" "runtime" "path" "strings")// GetCurFilename// Get current file name, without suffixfunc 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 htmlfunc 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 //logger.Panic("panic 1") //logger.Fatal("fatal 1") var baiduMainUrl string //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：

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：
