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. ...
() // 初始化 reader 读文件 r := bufio.NewReader(f) // 初始化 3 个 byte slice,每次读取 3 个 byte b := make([]byte, 3) // 循环读取,直到读到文件的结尾, for { n, err := r.Read(b) if err != nil { fmt.Println("Error reading file:", err) break } fmt.Println(string(...
我们通过 NewReader(string) 构建一个 Reader 对象,随后就可以通过 Read() 读取Reader 的内容,以下是其使用:package main import ( "fmt" "strings" ) func main() { s := "Today is monday, what a great start!" sr := strings.NewReader(s) // read cap_sr := sr.Len() data := make([]...
*/ reader := bufio.NewReader(file) //文件若不是换行结尾,就算出错 str, err := reader.ReadString('\n') if err != nil { fmt.Println("read string failed,err:", err) return } fmt.Printf("read str success,result:%s\n", str) } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12...

答案是嵌入类型字段的类型名会被当成该字段的名字。继续刚才的例子,如果我想要在NTFS中引用FileSystem的函数,则需要这样写: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 type FileSystem struct{MetaData[]byte}func(fs*FileSystem)Read(){}func(fs*FileSystem)Write(){}typeNTFSstruct{*FileSystem}// fs...
