php - 如何使用 PHP Bitly v4 缩短 URL？

Question

我有 Bitly v3 的代码，它运行良好。

<?php
$login = 'login-code-here';
$api_key = 'api-key-here';
$long_url = 'https://stackoverflow.com/questions/ask';

$ch = curl_init('http://api.bitly.com/v3/shorten?login='.$login.'&apiKey='.$api_key.'&longUrl='.$long_url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$res = json_decode($result, true);
echo $res['data']['url']; // bit.ly/2PcG3Fg
?>

但是，在较新的版本中如何做到这一点？上面的示例使用了 API key ，但它已被弃用以支持 OAuth 请求。

如何使用 Bitly v4 缩短 URL？

Answer 1

获取通用访问 token

转到您的 Bitly，单击右上角的汉堡菜单 > 设置 > 高级设置 > API 支持 > 单击链接通用访问 token 。输入您的密码并生成通用 token 。这就是您将用于身份验证的内容。

参见 https://dev.bitly.com/v4_documentation.html并查找使用单个帐户的应用程序部分。

根据 https://dev.bitly.com/v4/#section/Application-using-a-single-account 身份验证发生了一些变化.

How you authenticate to the Bitly API has changed with V4. Previously your authentication token would be provided as the access_token query parameter on each request. V4 instead requires that the token be provided as part of the Authorization header on each request.

代码

请参阅此文档 https://dev.bitly.com/v4/#operation/createFullBitlink获取有关 Bitly 期望的信息。

在 v4 中，您可以像这样在每个请求的 header 中使用通用 token 作为承载:

<?php

$long_url = 'https://stackoverflow.com/questions/ask';
$apiv4 = 'https://api-ssl.bitly.com/v4/bitlinks';
$genericAccessToken = 'your-token';

$data = array(
    'long_url' => $long_url
);
$payload = json_encode($data);

$header = array(
    'Authorization: Bearer ' . $genericAccessToken,
    'Content-Type: application/json',
    'Content-Length: ' . strlen($payload)
);

$ch = curl_init($apiv4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$result = curl_exec($ch);

print_r($result);

请求

您发送的 JSON 将如下所示:

{"long_url":"https:\/\/st​​ackoverflow.com\/questions\/ask"}

响应

{
   "created_at":"1970-01-01T00:00:00+0000",
   "id":"shortcode-link-id-here",
   "link":"shortcode-link-here",
   "custom_bitlinks":[

   ],
   "long_url":"https://stackoverflow.com/questions/ask",
   "archived":false,
   "tags":[

   ],
   "deeplinks":[

   ],
   "references":{
      "group":"group-link-here"
   }
}

编辑

评论中有要求只查看短链接输出。为此，只需像这样调整代码:

<?php
$long_url = 'https://stackoverflow.com/questions/ask';
$apiv4 = 'https://api-ssl.bitly.com/v4/bitlinks';
$genericAccessToken = 'your-token';

$data = array(
    'long_url' => $long_url
);
$payload = json_encode($data);

$header = array(
    'Authorization: Bearer ' . $genericAccessToken,
    'Content-Type: application/json',
    'Content-Length: ' . strlen($payload)
);

$ch = curl_init($apiv4);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $payload);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
$result = curl_exec($ch);
$resultToJson = json_decode($result);

if (isset($resultToJson->link)) {
    echo $resultToJson->link;
}
else {
    echo 'Not found';
}

结果(假设上面的文件是test.php)

php test.php
