PHP cURL如何发送JSON POST请求，还包括URL查询字符串？

Question

我正在尝试将带有JSON数据的POST请求提交到api端点。端点需要一个传递api凭据的查询字符串，而且还需要发布JSON数据。

[当我尝试使用PHP cURL进行此操作时，如下所示，显然已删除了查询字符串-因此，由于缺少api键，api拒绝了该请求。

[在测试对api端点的访问权限时，我可以使用Postman轻松完成此操作。

如何使cURL请求包含both查询字符串和JSON POST主体？

示例代码：

// $data is previously defined as an array of parameters and values.

$url = "https://api.endpoint.url?api_key=1234567890";

$ch = curl_init();
$json = json_encode($data);

curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
    'Content-Type: application/json',
    'Content-Length: ' . strlen($json)
] 

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);

您做得差不多了。

有时您需要放松SSL验证。否则，更新php ca bundle：https://docs.bolt.cm/3.7/howto/curl-ca-certificates

添加以下内容：

$headers = array(
  "Content-type: application/json;charset=UTF-8",
  "Accept-Encoding: gzip,deflate",
  "Content-length: ".strlen($json),
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 300);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_ENCODING, "identity, deflate, gzip");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLINFO_HEADER_OUT, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);

$result = curl_exec($ch);
$httpcode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);

有时您也需要更改编码：

$result = utf8_decode($result);

并检查返回的数据。
