我正在从用户处获取实际的位置地址,并尝试安排它创建一个URL,以后可以从Google地理编码API获取
JSON响应.
最终的URL字符串结果应该类似于this one,没有空格：
07001
我不知道如何替换我的URL字符串中的空格,而是使用逗号.我读了一些关于字符串和正则表达式的包,我创建了以下代码：
package main
import (
"fmt"
"bufio"
"os"
"http"
)
func main() {
// Get the physical address
r := bufio.NewReader(os.Stdin)
fmt.Println("Enter a physical location address: ")
line,_,_ := r.ReadLine()
// Print the inputted address
address := string(line)
fmt.Println(address) // Need to see what I'm getting
// Create the URL and get Google's Geocode API JSON response for that address
URL := "http://maps.googleapis.com/maps/api/geocode/json?address=" + address + "&sensor=true"
fmt.Println(URL)
result,_ := http.Get(URL)
fmt.Println(result) // To see what I'm getting at this point
}
你可以使用
strings.Replace.
package main
import (
"fmt"
"strings"
)
func main() {
str := "a space-separated string"
str = strings.Replace(str," ",",-1)
fmt.Println(str)
}
如果您需要更换多个东西,或者您需要一遍又一遍地进行相同的更换,最好使用strings.Replacer：
package main
import (
"fmt"
"strings"
)
// replacer replaces spaces with commas and tabs with commas.
// It's a package-level variable so we can easily reuse it,but
// this program doesn't take advantage of that fact.
var replacer = strings.NewReplacer(" ","\t",")
func main() {
str := "a space- and\ttab-separated string"
str = replacer.Replace(str)
fmt.Println(str)
}
当然,如果要替换编码的目的,例如URL编码,那么可能最好使用专门为此目的的功能,例如url.QueryEscape
