twitter个人资料关注者使用u​​serid计算

Question

我需要获得推特个人资料。

问题是我在这里没有获得令牌值，但我确实拥有Twitter帐户用户ID。

我们可以根据这些基本数据获得关注者的数量吗？

Answer 1

无论哪种方式，您都需要令牌，因为需要对Twitter API的所有请求执行身份验证。但要获得该令牌，使用 Application-only authentication 并不复杂。

首先，您需要创建一个 Twitter App 来获取 api密钥和 api secret 。

现在，只需获取持票人令牌：

$encoded_consumer_key = urlencode(CONSUMER_KEY);
$encoded_consumer_secret = urlencode(CONSUMER_SECRET);
$bearer_token = $encoded_consumer_key.':'.$encoded_consumer_secret;
$base64_consumer_key = base64_encode($bearer_token);
$url = "https://api.twitter.com/oauth2/token";
$headers = array(
        "POST /oauth2/token HTTP/1.1",
        "Host: api.twitter.com",
        "User-Agent: Twitter Application-only OAuth App",
        "Authorization: Basic ".$base64_consumer_key,
        "Content-Type: application/x-www-form-urlencoded;charset=UTF-8",
        "Content-Length: 29"
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, "grant_type=client_credentials");
$header = curl_setopt($ch, CURLOPT_HEADER, 1);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$response = curl_exec ($ch);
curl_close($ch);
$output = explode("\n", $response);
$bearer_token = '';
foreach($output as $line) {
    if ($line !== false) {
        $bearer_token = $line;
    }
}
$bearer_token = json_decode($bearer_token);
$bearer_token = $bearer_token->{'access_token'};

现在您已拥有不记名令牌，您可以使用* user_id *为用户制作lookup：

$url = "https://api.twitter.com/1.1/users/lookup.json";
$formed_url = '?user_id='.$user_id;
$headers = array(
        "GET /1.1/users/lookup.json".$formed_url." HTTP/1.1",
        "Host: api.twitter.com",
        "User-Agent: Twitter Application-only OAuth App",
        "Authorization: Bearer ".$bearer_token."",
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url.$formed_url);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec ($ch);
curl_close($ch);

然后在 $ response （它是 json ）中，您拥有所需的一切，包括 followers_count 。
