php - 使用 simplexml_load_file() 无法读取 xml 文件；

Question

当我使用 simplexml_load_file () 函数时，我从在线 xml 文件中读取数据时遇到问题；我遇到了一个错误。我的代码PHP：

$url = "https://www.bidv.com.vn/ServicesBIDV/ExchangeRateServlet";
$xml = simplexml_load_file($url);
echo '<pre>';
print_r($xml);
echo '</pre>';

输入错误

Warning: simplexml_load_file(https://www.bidv.com.vn/ServicesBIDV/ExchangeRateServlet): failed to open stream: HTTP request failed! HTTP/1.1 403 Forbidden in D:\All In One\xammp\htdocs\ty_gia_api\index.php on line 12

尝试从 URL 获取内容，例如：

$url = "https://www.bidv.com.vn/ServicesBIDV/ExchangeRateServlet";
$xml = simplexml_load_string(shell_exec("curl -k '$url'"));
echo '<pre>';
print_r($xml);
echo '</pre>';

我看到您尝试获取的页面不是 XML，而是 JSON。这将起作用：

$url = 'https://www.bidv.com.vn/ServicesBIDV/ExchangeRateServlet';
$data = json_decode(shell_exec("curl -k '$url'"), 1);
echo '<pre>';
print_r($data);
echo '</pre>';

var_dump($data);
