Golang json garbled solution

Golang json garbled code can be solved by using the "encoding/json" package in the golang program to encode and decode the json object.

Recommended: golang tutorial

golang encodes and decodes json objects Example:

package main
import (
    "fmt"
    "encoding/json"
)
func main() {
    // json encode
    j1 := make(map[string]interface{})
    j1["name"] = "PHP中文网"
    j1["url"] = "//m.sbmmt.com/"
    js1, err := json.Marshal(j1)
    if err != nil {
        panic(err)
    }
    println(string(js1))
    // json decode
    j2 := make(map[string]interface{})
    err = json.Unmarshal(js1, &j2)
    if err != nil {
        panic(err)
    }
    fmt.Printf("%#v\n", j2)
}

golang standard library encoding/json is used To process json data, it has two sets of functions or methods to process json data.

Encoding function

Encoding function: func Marshal(v interface{}) ([]byte, error)

Encoding rules: Recursively traverse v. A value in v implements the Marshaler interface and calls the MarshalJSON method to encode. If there is no such method but encoding.TextMarshl is implemented, use MarshalText to encode.

Decoding function

Decoding function: func Unmarshal(data []byte, v interface{}) error

data is a JSON data

v is Pointer to store decoded data

error error type returned
