用golang分割字符串[关闭]

Question

I have two arguments name and value, that I am trying to parse at runtime.

At run time I am passing the following values:

name = text,text,text,text,text
value = 0 ,285,404,6,24

Currently the output is as following;

Parameters: {"text,text,text,text,text":"0,285,404,6,24"}

when actually it must display as,

Parameters: {"text":"0"}
Parameters: {"text":"285"}
Parameters: {"text":"404"}
Parameters: {"text":"6"}
Parameters: {"text":"24"}

Following is my code;

package main

import "fmt"

func main() {
   var m string
   var matchField = []string{"index,index,index,index"}
   var matchValue =[]string{"29,4,87,54"}

   for i := 0 ; i < 1 ; i++ {
        m = parameter(matchField[i], matchValue[i])
        fmt.Printf("Result: %s
", m)
   }
}


func parameter(name string, value string) (matcher string) {
    var result string
    if name != "" || value != "" {
            result = fmt.Sprintf("{\"%s\":\"%s\"}", name, value)
    }
    return result
}

I wanted to know how to display the output accurately.

You need to use strings.Split to create the array, instead of an array with a single element:

play.golang.org/p/b5rffvBUwqd

package main

import "fmt"
import "strings"

func main() {
   var m string
   matchField := strings.Split("index,index,index,index", ",")
   matchValue := strings.Split("29,4,87,54", ",")

   for i := 0 ; i < len(matchField); i++ {
        m = parameter(matchField[i], matchValue[i])
        fmt.Printf("Parameters: %s
", m)
   }
}


func parameter(name string, value string) (matcher string) {
    var result string
    if name != "" || value != "" {
            result = fmt.Sprintf("{\"%s\":\"%s\"}", name, value)
    }
    return result
}
