1. 读取整个文件到内存中 使用ioutil 库的ReadFile()可以把整个文件读到内存中,在日常开发中,这是读文件使用频率最多的方法,也是最基本一个函数。下面代码展示了如何使用这个函数。 package main import ( "fmt" "os" ) func main() { data, err := os.ReadFile("./file.txt") if err != nil { f...
func ReadFile funcReadFile(filenamestring)([]byte,error) ReadFile reads the file named by filename and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported. ...
1 func ReadFile(filename string) ([]byte, error) ReadFile reads the file named by filename and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported. func...

The example reads the file by small 16 byte portions. buf := make([]byte, 16) We define an array of 16 bytes. Advertisementsfor { n, err := reader.Read(buf) if err != nil { if err != io.EOF { log.Fatal(err) } break } fmt.Print(string(buf[0:n])) } ...
