如何使用cURL获取jSON数据并对其进行解码？
提问于 2013-05-23 04:24:23
所以我有一个返回jSON对象的链接，我需要将它解码并放入PHP中的变量中。
URL
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.

[USER=118053]Frenchy[/USER] and [USER=4863]Wolfbane[/USER]那么，如何提取jSON对象并将其放入PHP中的正确变量中，以便稍后使用呢？
变量，如：$username、$user_id、$message、$title、$discussionState等。
我只需要知道如何检索jSON对象，然后将数据提取到中的变量中。
我现在可以获得PHP数组，但在调用正确的值时遇到了一些问题。这是数组。
阵列(计数=> 1线程=>阵列( 13 =>阵列( thread_id => 13 node_id => 4 title =>论坛集成即将完成！reply_count => 0 view_count => 0 user_id => 59 username => Faeron post_date => 1369257302 sticky => 0 discussion_state => visible discussion_open => 1 discussion_type => first_post_id => 23 first_post_likes 0 1369257302 23 # 59 # Faeron 1 content数组(计数1内容数组( 23数组( 23 13user_id => 59 username => Faeron post_date => 1369257302 message =>自从我们开始将phanime论坛与主站点整合以来，已经有一段时间了。我们现在已经完成了与phanime论坛和主站点的集成。你不会再注意到有两个平台在运行phanime，而是只有一个。我们的下一步是主题论坛，使其看起来像主网站！ip_id => 268 message_state => visible attach_count => 0 position => 0 likes => 0 like_users => a:0:{} warning_id => 0 warning_message => )))
现在假设这个数组被命名为$array，然后为了获得第一个元素的值"count“，我不能只说：print $array["[count]"] <--这会返回一个错误。
对于值为数组本身的元素，它是[threads]元素。如何获取[thread_id]元素的值？

我想这将会回答你的问题：

// 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);

要获得不需要使用cURL的对象(您正在将另一个dll加载到内存中并具有另一个依赖项，除非您确实需要curl，否则我将坚持使用内置的php函数)，您可以使用一个简单的php (File_get_contents)函数：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);然后json_decode()将JSON解析为一个PHP对象，如果将true传递给第二个参数，则解析为一个数组。http://php.net/manual/en/function.json-decode.php
例如：
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json)); // Object
var_dump(json_decode($json, true)); // Associative arrayStack Overflow用户

您可以对Curl使用此命令：
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;
} 然后阅读Json：
$result=getdata("https://example.com");然后：
///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>";
}您还可以使用以下命令：
echo '<p>Name : '.$data['result']['name'].'</p>
<img src="'.$data['result']['pic'].'"><br>';希望这能帮上忙。
