Question

我正在尝试从IOT应用程序获取JSON。我可以将数据发布到我的IOT应用程序，这样我的连接就可以了，但是无法得到响应。我只会收到一个不允许的错误。

我使用以下代码：

$ch = curl_init();
curl_setopt($ch, CURLOPT_VERBOSE, true);

$verbose = fopen('php://temp', 'w+');
curl_setopt($ch, CURLOPT_STDERR, $verbose);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$endpoint_url);
$result = curl_exec($ch);

if ($result === FALSE) {
    printf("cUrl error (#%d): %s<br>\n", curl_errno($ch),
        htmlspecialchars(curl_error($ch)));
}
curl_close($ch);

rewind($verbose);
$verboseLog = stream_get_contents($verbose);

echo "Verbose information:\n<pre>", htmlspecialchars($verboseLog), "</pre>\n";

但是我得到的只是以下内容：

如何获取数据？

Answer 1

您没有在curl请求中指定Request类型，它会自动将其默认为GET。将以下内容添加到您的代码中。

curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'POST');

尝试使用PHP从物联网获取数据
