php - 在 Geckoboard php curl 中出现无效的 JSON 错误

Question

我正在尝试使用 php curl 在 Geckoboard 数据集中添加数据，但我收到了无效的 json 错误。请帮我。

请检查我的以下代码：

$ch = curl_init('https://api.geckoboard.com/datasets/sales.datasetidhere/data');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = array("articlePublished" => "6"); 
$data = json_encode($data);
curl_setopt($ch, CURLOPT_POST, 1); 

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_USERPWD, "Key:");

curl_setopt( $ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
# Return response instead of printing.
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

curl_setopt($ch, CURLOPT_POSTFIELDS, 'data='.$data);

$response = curl_exec($ch);
$headers = curl_getinfo($ch);
print_r( $headers );
print_r( $response );

以下是响应： {"error":{"message":"Invalid JSON was received by the server."}}
