Question

我是php的初学者，并且有一个我想从中读取数据的API。在我的本地主机上，它可以正常工作，并且所有输出均符合预期。 Postman应用程序也是如此。当我从本地主机而不是本地API访问Web API时，它甚至可以工作。但是，只要我尝试在实时网站上获得结果，它就会返回NULL。

注意：它是一个WordPress网站。 Localhost是通过Xampp完成的。通过SiteGround在线托管。我过去曾做过这项工作，但我不知道突然停止工作的情况（也许我做了些改动）。 API是具有预配置API的WordPress许可证管理器插件。域名/ IP /和客户机密不是原始的。

在我的本地主机上，此代码产生此响应，而这正是我需要的：

$url = "https://example.com/wp-json/lmfwc/v2/licenses?consumer_key=ck_xxxx&consumer_secret=cs_yyy";

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => $url,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "", 
  CURLOPT_FOLLOWLOCATION => True,
  CURLOPT_HTTPHEADER =>array (
     'Accept: application/json'),
  CURLOPT_SSL_VERIFYHOST => false,
  CURLOPT_SSL_VERIFYPEER => false,
));

$response = curl_exec($curl);
print_r($response) ?> <br><br> <?php ;
$json_response =json_encode($response);
print_r($json_response) ?> <br><br> <?php ;
$info_display = curl_getinfo($curl);
print_r ($info_display); ?> <br><br> <?php 
$array_response = json_decode($response);
print_r($array_response); ?> <br> <br><?php 
$err = curl_error($curl);
var_dump($err); ?> <br> <br><?php 
curl_close($curl);

那我就能得到这个结果：

//print_r($response) ?> <br><br> <?php ;

我在前端将其返回：

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Answer 1

您应该将以下行放入脚本的第一行。将显示所有错误，然后，应在生产环境中删除此行

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Answer 2

在wordpress API可以输出之前，您似乎正在向输出缓冲区中写入一些内容。

我会检查您在localhost上的环境是否匹配生产。例如插件，主题文件和wordpress核心。您的主题文件可能在标题中回显了某些内容。

其他建议是：

如果邮递员正在制作产品，则您的cUrl设置存在问题

这是一个SSL问题-您已禁用在自己的网址上验证SSL-假设您的本地主机上没有SSL，但是Siteground阻止了来自本身未使用SSL的SSL网站的网址请求。还需要将编码集设置为空字符串吗？

Answer 3

已解决，但我必须承认我不知道最终解决了什么。但这与Siteground问题无关。最后尝试了一千件事，然后我删除了应该运行php代码的整个子页面。我创建了一个新页面，并尝试了一遍又一遍，它仍然有效。很奇怪，但是感谢您的提示和技巧。

PHP API调用适用于本地主机，邮递员，但不适用于实时网站
