如何从 CI 控制器中的 REST API 获取数据？

Question

我有一个 API 源并想在我的控制器中处理它。

$user    = "myuser";
$pass    = "mypass";

$url     = "http://myurlforapi/StockSummary?userid='5'";
            
//$url   = "https://pokeapi.co/api/v2/pokemon/132/";        
    
    $opts    = array(
            'http'  => array(
                        'method'    => "GET",
                        'header'    => "Authorization: Basic " . base64_encode("$user:$pass")                 
      )
    );
    
    $context = stream_context_create($opts);
    
    // Open the file using the HTTP headers set above
    $data= file_get_contents($url, false, $context);
    
    print($data);

当我将 URL 更改为 pokeapi.co 时，会显示数据。但是，当我使用 myurlforapi 时，不会显示任何数据。我错过了什么吗？或者在我的域中需要做一些配置？

更新：

A PHP Error was encountered
Severity: Warning

Message: file_get_contents(http://myurlforapi/StockSummary?userid=5): failed to open stream: Connection refused

Filename: backend/Dashboard.php

Line Number: 51

Backtrace:

File: /home/u9354272/public_html/xxx/modules/dashboard/controllers/backend/Dashboard.php
Line: 51
Function: file_get_contents

File: /home/u9354272/public_html/xxx/index.php
Line: 339
Function: require_once

注意：当我使用 Postman 时，它可以工作。当我在我的虚拟主机中使用它时，它不起作用

您没有将凭据正确传递给 base64 编码函数。改变这个

$opts    = array(
        'http'  => array(
                    'method'    => "GET",
                    'header'    => "Authorization: Basic " . base64_encode("$user:$pass")                 
  )
);

到这里

$opts    = array(
        'http'  => array(
                    'method'    => "GET",
                    'header'    => "Authorization: Basic " . base64_encode($user . ':' . $pass)                 
  )
);
