无法在本地主机上检索JSON对象 [英] cant retrieve JSON object on localhost

问题描述

我正在尝试在本地主机上检索JSON对象，问题是它不会输出任何内容. JSON对象可能如下所示:

I'm trying to retrieve JSON Objects on my localhost, the issue is that it wont output anything. The JSON objects could look like following:

[
{
    NAME: "Hearthstone",
    PLAYER1: "Rdu ",
    PLAYER2: "Savjz ",
    status: 2,
    meta: "LIVE"
},
{
    NAME: "League of Legends",
    PLAYER1: "Team King ",
    PLAYER2: "EDG ",
    status: 2,
    meta: "28.12."
}]

php检索对象.

$url = "http://localhost:8888/crawl_JSON.php";
$json = file_get_contents($url);
$json_output = json_decode($json);


echo $json_output;

为什么不输出任何东西?

Why don't it output anything?

推荐答案

请注意，json_decode()返回一个对象，您不能echo您需要使用var_dump或print_r.如果您想回显，则可以回显JSON字符串.

Note that json_decode() returns an object, you cannot echo you will need to use var_dump or print_r. If you want to echo , you can echo the JSON string.

$url = "http://localhost:8888/crawl_JSON.php";
$json = file_get_contents($url);
echo $json;
$json_output = json_decode($json);

var_dump($json_output);

在 crawl_JSON.php 内，您需要echo JSON，需要确保它有效.

And inside of crawl_JSON.php You need to echo the JSON, you will need to make sure it is valid.

<?php

echo '
[
    {
        "NAME": "Hearthstone",
        "PLAYER1": "Rdu ",
        "PLAYER2": "Savjz ",
        "status": 2,
        "meta": "LIVE"
    },
    {
        "NAME": "LeagueofLegends",
        "PLAYER1": "TeamKing",
        "PLAYER2": "EDG",
        "status": 2,
        "meta": "28.12."
    }
]
';
