如何使用 cURL 获取 jSON 数据并解码数据？

因此，我有一个返回 jSON 对象的链接，我需要将其解码并放入 PHP 中的变量中。

网址

api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1

这是它返回的对象

We've completely restructured ShadyCraft, and today will be the launch of the ShadyCraft beta.


Current Features
[LIST]
[*]Towns
[*]Nations
[*]All out wars
[*]A live update map
[*]No White-list
[*]Earn Money
[*]Griefing allowed where possible
[/LIST]
These are just some features which have a lot more things behind them. For instance, there is town and nation upkeep, tax, kingdoms, mayors, and kings.


We really wanted to have the server self-governed and this is why griefing and PvP are allowed where ever they are possible. All towns and nations cannot be griefed by other members. You can create a town and buy plots for it and expand the town as you wish.

那么，我如何提取 jSON 对象并将其放入 PHP 中以便纠正以后可以使用的变量呢？

变量如: $username、 $user_id、 $message、 $title、 $discussionState等等。

我只需要知道如何检索 jSON 对象，然后将数据提取到 PHP 中的变量中

我现在能够得到 PHP 数组，但是我在调用正确的值时遇到了一些麻烦。这是数组。

Array ([ count ] = > 1[ thread ] = > Array ([13] = > Array ([ thread _ id ] = > 13[ node _ id ] = > 4[ title ] = > 论坛集成几乎完成！[ response _ count ] = > 0[ view _ count ] = > 0[ user _ id ] = > 59[ username ] = > 法隆[ post _ date ] = > 1369257302[粘性] = > 0[ talk _ state ] = > 可见[ talk _ open ] = > 1[ talk _ type ] = > [ first _ post _ id ] = > 23[ first _ post _ like ] = > 0[ last _ post _ date ] = > 1369257302 [ last _ post _ id ] = > 23[ last _ post _ user _ id ] = > 59[ last _ post _ username ] = > Faeron [ prefix _ id ] = > 1[ content ] = > Array ([ count ] = > 1[ content ] = > Array ([23] = > Array ([ post _ id ] = > 23[ thread _ id ] = > 13[ user _ id ] = > 59[用户名] = > Faeron [ post _ date ] = > 1369257302[ message ] = > It’s 自从我们开始整合幻影论坛以来已经有一段时间了主站点。我们现在已经完成了与幻影的整合论坛和主站点。你不会再注意到有两个运行 phanime 的平台，但只有一个。我们的下一步是对论坛进行主题设计，使其看起来像主站点! [ ip _ id ] = > 268 [ message _ state ] = > visible [ attc _ count ] = > 0[ position ] = > 0[ like ] = > 0[ like _ users ] = > a: 0: {}[ police _ id ] = > 0[ police _ message ] = >))))

现在让我们假设这个数组被命名为 $array，然后为了得到第一个元素的值“[ count ]”，我不能只说下面的内容吗: print $array["[count]"] < ——这将返回一个错误。

那么具有作为数组本身的值的元素(即 [threads]元素)又如何呢。我如何得到，也许是 [thread_id]元素的值？

Use this function: http://br.php.net/json_decode This will automatically create PHP arrays.

小开

to get the object you do not need to use cURL (you are loading another dll into memory and have another dependency, unless you really need curl I'd stick with built in php functions), you can use one simple php file_get_contents(url) function: http://il1.php.net/manual/en/function.file-get-contents.php

$unparsed_json = file_get_contents("api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1");


$json_object = json_decode($unparsed_json);

then json_decode() parses JSON into a PHP object, or an array if you pass true to the second parameter. http://php.net/manual/en/function.json-decode.php

For example:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';


var_dump(json_decode($json));           // Object
var_dump(json_decode($json, true));     // Associative array

最佳答案

I think this one will answer your question :P

$url="https://.../api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=‌desc&limit=1&grab_content&content_limit=1";

Using cURL

//  Initiate curl
$ch = curl_init();
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);


// Will dump a beauty json :3
var_dump(json_decode($result, true));

Using file_get_contents

$result = file_get_contents($url);
// Will dump a beauty json :3
var_dump(json_decode($result, true));

Accessing

$array["threads"][13/* thread id */]["title"/* thread key */]

And

$array["threads"][13/* thread id */]["content"/* thread key */]["content"][23/* post id */]["message" /* content key */];

You can Use this for Curl:

function fakeip()
{
return long2ip( mt_rand(0, 65537) * mt_rand(0, 65535) );
}


function getdata($url,$args=false)
{
global $session;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("REMOTE_ADDR: ".fakeip(),"X-Client-IP: ".fakeip(),"Client-IP: ".fakeip(),"HTTP_X_FORWARDED_FOR: ".fakeip(),"X-Forwarded-For: ".fakeip()));
if($args)
{
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$args);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1:8888");
$result = curl_exec ($ch);
curl_close ($ch);
return $result;
}

Then To Read Json:

$result=getdata("https://example.com");

Then :

///Deocde Json
$data = json_decode($result,true);
///Count
$total=count($data);
$Str='<h1>Total : '.$total.'';
echo $Str;
//You Can Also Make In Table:
foreach ($data as $key => $value)
{
echo '  <td><font  face="calibri"color="red">'.$value[type].'   </font></td><td><font  face="calibri"color="blue">'.$value[category].'   </font></td><td><font  face="calibri"color="green">'.$value[amount].'   </font></tr><tr>';


}
echo "</tr></table>";
}

You Can Also Use This:

echo '<p>Name : '.$data['result']['name'].'</p>
<img src="'.$data['result']['pic'].'"><br>';

Hope this helped.

You can use this:

curl_setopt_array($ch, $options);
$resultado = curl_exec($ch);
$info = curl_getinfo($ch);
print_r($info["url"]);

小开

you can also use

$result = curl_exec($ch);
return response()->json(json_decode($result));
