"io/ioutil"
"net/http"
)

func main() {
url := "https://api.twitter.com/1.1/search/tweets.json"
response, err := http.Get(url)
if err != nil {
fmt.Println(err)
return
}
defer response.Body.Close()

body, err := ioutil.ReadAll(response.Body)
if err != nil {
	fmt.Println(err)
	return
}

var result map[string]interface{}
err = json.Unmarshal(body, &result)
if err != nil {

I have my php code. How to create something like this in Go?

<?php

     'ignore_errors'=>true,
     'method'=>'GET'
   )
));
$response = json_decode(file_get_contents($url, false, $context));

包括这样的内容:

package main

import (
	"encoding/json"
	"fmt"
	"net/http"
)

func main() {
	resp, err := http.Get("https://api.twitter.com/1.1/search/tweets.json")
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	fmt.Printf("%#v\n", resp)

	dec := json.NewDecoder(resp.Body)
	if dec == nil {
		panic("Failed to start decoding JSON data")
	}

	json_map := make(map[string]interface{})
	err = dec.Decode(&json_map)
	if err != nil {
		panic(err)
	}

	fmt.Printf("%v\n", json_map)
}
英文:

Something like this:

package main

import (
	"encoding/json"
	"fmt"
	"net/http"
)

func main() {
	resp, err := http.Get("https://api.twitter.com/1.1/search/tweets.json")
	if err != nil {
		panic(err)
	}
	defer resp.Body.Close()

	fmt.Printf("%#v\n", resp)

	dec := json.NewDecoder(resp.Body)
	if dec == nil {
		panic("Failed to start decoding JSON data")
	}

	json_map := make(map[string]interface{})
	err = dec.Decode(&json_map)
	if err != nil {
		panic(err)
	}

	fmt.Printf("%v\n", json_map)
}
