golang （*bufio.Reader)的读取方法

bufReader.ReadBytes('\n')和 bufReader.ReadString('\n')在读到文件最后一行时，会同时返回内容line和io.EOF。而bufReader.Read()读取到末尾时，会先返回内容，然后再下一次迭代时才返回io.EOF

package main

import (

"fmt"

"github.com/jonas-p/go-shp"

"log"

"reflect"

)

func main() {

// open a shapefile for reading

  reader, err := shp.Open("E:/example.shp")

if err != nil {

log.Fatal(err)

}

defer reader.Close()

// fields from the attribute table (DBF)

  fields := reader.Fields()

//fmt.Println(reader.AttributeCount())

//for k, f := range fields {

// fmt.Println(k,f)

//}

////fmt.Println(reader.Attribute(0))

//loop through all features in the shapefile

  for reader.Next() {

n, p := reader.Shape()

point := p.(*shp.Point)

x := point.X

y := point.Y

fmt.Println(x, y)

// print feature

      fmt.Println(reflect.TypeOf(p).Elem(), p.BBox())

// print attributes

      for k, f :=range fields {

val := reader.ReadAttribute(n, k)

fmt.Printf("\t%v: %v\n", f, val)

}

fmt.Println()

}

}
