PHP API调用适用于本地主机、邮递员，但不适用于实时网站

我在php方面相当初级，有一个API，我想从中读取数据。在我的本地主机上，它运行良好，所有输出都如预期。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。但一旦我试图在我的直播网站上得到结果，它就会返回NULL。

注意：这是一个WordPress网站。Localhost是通过Xampp完成的。通过SiteGround在线托管。我以前也有过这种工作，但我不知道发生了什么(也许我稍微更改了代码或其他什么(突然停止了工作。API是一个WordPress许可管理器插件，带有预先配置的API。域名/IP/和客户机密并非此处的原始信息。

$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);

在我的本地主机上，这段代码产生的响应正是我所需要的：

我的实时网站上的相同代码崩溃了。所以我需要评论一下//print_r($response) ?> <br><br> <?php ;

那么我就可以得到这样的结果：

从我的开发者控制台谷歌浏览器中的"网络"选项卡，我可以看到这一点。所有请求返回状态200：

编辑：将以下代码添加到我的php片段的开头，我通过php剪切插件将其添加到wordpress：

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

我在前端得到了回报：

在wordpress API可以输出之前，您似乎正在将某些内容写入输出缓冲区。

我会检查您在localhost上的环境是否与生产匹配。例如插件、主题文件和wordpress核心。您的主题文件可能正在回显标头中的某些内容。

其他建议是：

如果邮递员正在生产，那么你的cUrl设置有问题

这是SSL问题吗？假设您的本地主机上没有SSL，您已经禁用了在cUrl上验证SSL。但是，Siteground我阻止了来自本身不使用SSL的SSL站点的cUrl请求。您还需要将编码集设置为空字符串吗？

它已经解决了，但我必须承认，我不知道是什么最终解决了它。但它与Siteground问题无关。最后，我尝试了一千种方法，删除了本应运行php代码的整个子页面。我创建了一个新页面，试了一遍，结果成功了。很奇怪，但谢谢你的提示和窍门。

您应该将以下行放在脚本的第一行中。所有错误都会显示出来，之后，这行应该在生产环境中删除

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