Go语言标准库Json的使用.

2019PHP高薪工程师学习路线图....>>>

    GitHub上别人做的封装,挺好用的,推荐一下:https://github.com/bitly/go-simplejson  
      
    这个内置的标准库用起来还是很烦得,要知道对方发过来的type,不然只能自己分析反射.  
    package main  
      
    import (  
        "encoding/json"  
        "fmt"  
    )  
      
    type Status_slice [][]int  
      
    type Info struct {  
        IP    string  
        Block Status_slice  
    }  
      
    func main() {  
        var x Status_slice = [][]int{{1, 2}, {2, 3}}  
        var y Info = Info{"192.168.1.248", x}  
        fmt.Println(y)  
        b, e := json.Marshal(y)  
        fmt.Println(string(b), e)  
        fmt.Println(b)  
    }  
      
    //解码   
    package main  
      
    import (  
        "encoding/json"  
        "fmt"  
    )  
      
    type Status_slice [][]int  
      
    type Info struct {  
        IP    string  
        Block Status_slice  
    }  
      
    func main() {  
        var x Status_slice = [][]int{{0, 0}, {0, 0}}  
        var y Info = Info{"1", x}  
        a := `{"IP":"192.168.1.1","Block":[[1,1],[1,2]]}`  
        err := json.Unmarshal([]byte(a), &y)  
        fmt.Println(err, y)  
        Map := make(map[string]Status_slice)  
        Map[y.IP] = y.Block  
        fmt.Println(Map)  
    }
