+# Go 文件操作
+
+## 1.文本文件
+
+### 1.1.创建
+
+```go
+f,err := os.Create(fileName)
+defer f.Close()
+if err !=nil {
+    fmt.Println(err.Error())
+} else {
+    _,err=f.Write([]byte("要写入的文本内容"))
+    checkErr(err)
+}
+```
+
+### 1.2.读取
+
+```go
+f, err := os.OpenFile(fileName, os.O_RDONLY,0600)
+defer f.Close()
+if err !=nil {
+    fmt.Println(err.Error())
+} else {
+    contentByte,err=ioutil.ReadAll(f)
+    checkErr(err)
+    fmt.Println(string(contentByte))
+}
+```
+
+打开模式如下：
+
+```go
+//打开方式
+const (
+//只读模式
+O_RDONLY int = syscall.O_RDONLY // open the file read-only.
+//只写模式
+O_WRONLY int = syscall.O_WRONLY // open the file write-only.
+//可读可写
+O_RDWR int = syscall.O_RDWR // open the file read-write.
+//追加内容
+O_APPEND int = syscall.O_APPEND // append data to the file when writing.
+//创建文件,如果文件不存在
+O_CREATE int = syscall.O_CREAT // create a new file if none exists.
+//与创建文件一同使用,文件必须存在
+O_EXCL int = syscall.O_EXCL // used with O_CREATE, file must not exist
+//打开一个同步的文件流
+O_SYNC int = syscall.O_SYNC // open for synchronous I/O.
+//如果可能,打开时缩短文件
+O_TRUNC int = syscall.O_TRUNC // if possible, truncate file when opened.
+)
+```
