如何在PHP中使用Get url方法？

Question

$ curl 'https://api.follow.net/v3/domains/google.com' \ 
-u sk-4f8ae86206e39419k2h: 

我有上面的參考。我不知道如何應用這個使用PHP。

Answer 1

The documentation for the API states that the api uses `Basic Auth` for all authentication calls. 
<?php 

    function pre($data){ 
     echo '<pre>',print_r($data,true),'</pre>'; 
    } 


    $key='sk-4f8ae86206e39419k2h'; 

    $headers = array(
     'Content-Type:application/json', 
     'Authorization: Basic ' . $key . ':' 
    ); 

    $url='https://api.follow.net/v3/domains/google.com'; 

    $curl = curl_init(); 
    curl_setopt($curl, CURLOPT_URL,$url); 
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false); 
    curl_setopt($curl, CURLOPT_HEADER,true); 
    curl_setopt($curl, CURLOPT_HTTPHEADER, $headers); 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true); 
    $response = curl_exec($curl); 
    curl_close($curl); 
    $curl=null; 

    pre($response); 

?> 


This yields

     } 
    }

您可以使用file_get_contents（），但我不認爲它有提供外部參數的選項，例如您使用-u添加的參數。 所以更好的解決方案是使用PHP的CURL模塊。以下是示例代碼： -

<?php  
$url = 'https://api.follow.net/v3/domains/google.com'; 

$user = "sk-4f8ae86206e39419k2h"; 
$pass = "xdffggg" 

//open connection 
$ch = curl_init(); 

curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_USERNAME, $user); 
curl_setopt($ch, CURLOPT_USERPWD, $pass); 

//execute post 
$result = curl_exec($ch); 

curl_close($ch); 

// Use $result as per your requirement like 
var_dump($result); 

還有許多其他支持的選項。

交互模式啓用

php > $url = 'https://api.follow.net/v3/domains/google.com'; 
php > 
php > 
php > $user = "sk-4f8ae86206e39419k2h"; 
php > 
php > 
php > $pass = ""; 
php > $ch = curl_init(); 
php > 
php > curl_setopt($ch, CURLOPT_URL, $url); 
php > curl_setopt($ch, CURLOPT_USERNAME, $user); 
php > curl_setopt($ch, CURLOPT_USERPWD, $pass); 
php > $result = curl_exec($ch); 
{ 
    "error": { 
     "type": "invalid_request_error", 
     "message": "Unauthorized Request - No API Key", 
     "premium_data_points_required": null, 
     "premium_data_points_cost": null 
    } 
} 
php > curl_close($ch); 
php > var_dump($result); 
bool(true)

現在我在終端得到相同的輸出： -

deepak@deepak-PC: /temp_path $ curl 'https://api.follow.net/v3/domains/google.com' -u sk-4f8ae86206e39419k2h: 

{ 
    "error": { 
     "type": "invalid_request_error", 
     "message": "Unauthorized Request - Invalid API Key", 
     "premium_data_points_required": null, 
     "premium_data_points_cost": null 
}
