链接缩短服务 API 返回 Null [重复]

Question

我打算用这个api做一个链接缩短服务，本站的api地址如下：

http://mitly.ir/api.php

例如对于这个请求：

http://mitly.ir/api.php?url=https://google.com

这会输出 json：

{
    "longurl": "https:\/\/google.com",
    "shorturl": "http:\/\/mitly.ir\/12MxP",
    "stats": "http:\/\/mitly.ir\/stats.php?id=12MxP"
}

现在我写了下面的代码来使用这个api，可惜返回给我的输出是null：

//API Url
  $url = 'http://mitly.ir/api.php';
  //Initiate cURL.
  $ch = curl_init($url);
  //Tell cURL that we want to send a POST request.
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_HEADER, false);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_POSTFIELDS, "url=https://google.com");
  curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
  //Execute the request
  $result = curl_exec($ch);
  //echo $result;
  $response = json_decode($result, true);
  var_dump($response);
  echo "your url is :".$response['result']['shorturl'];

请帮我解决这个问题

从您的示例中，您需要 GET 请求：

$short = 'https://google.com';
$url = 'http://mitly.ir/api.php?url='.$short;
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));
    $result = curl_exec($ch);
    $response = json_decode($result, true);
    var_dump($response);
