package quotedprintable
import "mime/quotedprintable"
Package quotedprintable implements quoted-printable encoding as specified by RFC 2045.

Examples
Types
type Reader
type Reader struct { // contains filtered or unexported fields }
Reader 是 quoted-printable 解码器。
func NewReader
func NewReader(r io.Reader) *Reader
NewReader 返回一个 quoted-printable 读取器，从 r 解码。
Output:Example
package main
import (
"fmt"
"io"
"mime/quotedprintable"
"strings"
)
func main() {
for _, s := range []string{
`=48=65=6C=6C=6F=2C=20=47=6F=70=68=65=72=73=21`,
`invalid escape: <b style="font-size: 200%">hello</b>`,
"Hello, Gophers! This symbol will be unescaped: =3D and this will be written in =\r\none line.",
} {
b, err := io.ReadAll(quotedprintable.NewReader(strings.NewReader(s)))
fmt.Printf("%s %v\n", b, err)
}
}
Hello, Gophers! <nil>
invalid escape: <b style="font-size: 200%">hello</b> <nil>
Hello, Gophers! This symbol will be unescaped: = and this will be written in one line. <nil>
func (*Reader) Read
func (r *Reader) Read(p []byte) (n int, err error)
Read 从底层读取器读取并解码 quoted-printable 数据。
type Writer
type Writer struct { // Binary 模式将写入器的输入视为纯二进制，并将行尾字节作为二进制数据处理。 Binary bool // contains filtered or unexported fields }
A Writer is a quoted-printable writer that implements io.WriteCloser.
func NewWriter
func NewWriter(w io.Writer) *Writer
NewWriter 返回一个新的 Writer，写入到 w。
Output:Example
package main
import (
"mime/quotedprintable"
"os"
)
func main() {
w := quotedprintable.NewWriter(os.Stdout)
w.Write([]byte("These symbols will be escaped: = \t"))
w.Close()
}
These symbols will be escaped: =3D =09
func (*Writer) Close
func (w *Writer) Close() error
Close 关闭 Writer，将任何未写入的数据刷新到底层 io.Writer， 但不关闭底层的 io.Writer。
func (*Writer) Write
func (w *Writer) Write(p []byte) (n int, err error)
Write 使用 quoted-printable 编码将 p 写入底层 io.Writer。 它将行长度限制为 76 个字符。编码字节不会自动刷新直到 Writer 关闭。
