Php使用api键获取数据

我想做一个PHP页面发送喜欢的API从社会媒体面板，我有一个成员

他们给了我这个例子，但我不完全理解

示例代码：

<?php
   class Api
   {
      public $api_url = 'http://domain/api/v2'; // API URL

      public $api_key = ''; // Your API key

      public function order($data) { // add order
        $post = array_merge(array('key' => $this->api_key, 'action' => 'add'), $data);
        return json_decode($this->connect($post));
      }

      public function status($order_id) { // get order status
        return json_decode($this->connect(array(
          'key' => $this->api_key,
          'action' => 'status',
          'id' => $order_id
        )));
      }

      public function services() { // get services
        return json_decode($this->connect(array(
          'key' => $this->api_key,
          'action' => 'services',
        )));
      }

      public function balance() { // get balance
        return json_decode($this->connect(array(
          'key' => $this->api_key,
          'action' => 'balance',
        )));
      }


      private function connect($post) {
        $_post = Array();
        if (is_array($post)) {
          foreach ($post as $name => $value) {
            $_post[] = $name.'='.urlencode($value);
          }
        }
        $ch = curl_init($this->api_url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
        if (is_array($post)) {
          curl_setopt($ch, CURLOPT_POSTFIELDS, join('&', $_post));
        }
        curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)');
        $result = curl_exec($ch);
        if (curl_errno($ch) != 0 && empty($result)) {
          $result = false;
        }
        curl_close($ch);
        return $result;
      }
   }

   // Examples

   $api = new Api();

   $services = $api->services(); # return all services

   $balance = $api->balance(); # return user balance

   // add order

   $order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'quantity' => 100)); # Default

   $order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'quantity' => 100, 'keywords'=>"test, testing")); # SEO

   $order = $api->order(array('service' => 1, 'link' => 'http://example.com/test', 'comments' => "good pic\ngreat photo\n:)\n;)")); # Custom Comments

   $order = $api->order(array('service' => 4, 'link' => 'http://example.com/test', 'quantity' => 100, 'usernames'=>"test, testing", 'hashtags'=>"#goodphoto")); # Mentions with Hashtags

   $order = $api->order(array('service' => 5, 'link' => 'http://example.com/test', 'usernames' => "test\nexample\nfb")); # Mentions Custom List

   $order = $api->order(array('service' => 6, 'link' => 'http://example.com/test', 'quantity' => 100, 'hashtag'=>"test")); # Mentions Hashtag

   $order = $api->order(array('service' => 7, 'link' => 'http://example.com/test', 'quantity' => 1000, 'username'=>"test")); # Mentions User Followers

   $order = $api->order(array('service' => 8, 'link' => 'http://example.com/test', 'quantity' => 1000, 'media'=>"http://example.com/p/Ds2kfEr24Dr")); # Mentions Media Likers

   $order = $api->order(array('service' => 9, 'link' => 'http://example.com/test', 'quantity' => 1000, 'usernames'=>"test")); # Mentions

   $order = $api->order(array('service' => 10, 'link' => 'http://example.com/test')); # Package

   $order = $api->order(array('service' => 12, 'link' => 'http://example.com/test', 'quantity' => 100, 'runs' => 10, 'interval' => 60)); # Drip-feed

   $order = $api->order(array('service' => 11, 'username' => 'username', 'min' => 100, 'max' => 110, 'posts' => 0,'delay' => 30)); # Subscriptions

   $status = $api->status($order->order); # return status, charge, remains, start count

?>

现在，我想在我的PHP页面上看到“获取平衡”，但我做不到。我填写API URL和API密钥。你能帮我做什么吗

谢谢

您可以通过在API上调用

balance（）

来使用它，就像这样

$api=newapi（）；
$response=$api->balance（）；
//响应具有“余额”和“货币”属性，可以这样访问；
呼应“你的平衡是”$回应->平衡。" " . $响应->货币；

投票否决，因为它过于宽泛，主要是基于意见-您可以对此进行研究，oAuth 2.0也是一个问答，如果您在现有代码中遇到某些特定问题，我们可以帮助您，但我们不是来为您编写的。您链接到的cde（应该包含在实际问题中）只是一个类。由于这基本上是PHP 101，我建议您阅读一些关于PHP和OOP的入门教程，因为您肯定会很快遇到更多的问题。感谢您的回答，但我收到了以下错误“可捕获的致命错误：stdClass类的对象无法在第71行转换为字符串”@Can1-该错误发生在哪个文件中？在您显示的代码的第71行中，我看不到任何“对象到字符串”的转换。我在页面末尾添加了@jack wilsdon代码，这些代码给出了该错误。现在我试着用“print_r（$balance）”，而不是“echo$balance”，我得到了这些“stdClass对象（[balance]=>0.45912[currency]=>USD）”我怎么能只得到余额部分？@Can1-当然。这些方法返回对象。Do:

$data=$api->balance（）要回送它，您还应该检查是否得到了有效的响应：
echo-isset（$data->balance）$数据->余额：“无效响应”。添加了解释如何访问返回对象属性的代码。
