PHP中利用Curl发送Post、Get、Del、Put、Patch请求的方法

使用Curl发送Post请求

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.example.com/api/v1/post",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\n  \"name\": \"John Doe\",\n  \"age\": \"30\"\n}",
  CURLOPT_HTTPHEADER => array(
    "Content-Type: application/json"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

使用Curl发送Get请求

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.example.com/api/v1/get",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "GET",
  CURLOPT_HTTPHEADER => array(
    "Content-Type: application/json"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

使用Curl发送Del请求

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.example.com/api/v1/del",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "DELETE",
  CURLOPT_HTTPHEADER => array(
    "Content-Type: application/json"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

使用Curl发送Put请求

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.example.com/api/v1/put",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "PUT",
  CURLOPT_POSTFIELDS => "{\n  \"name\": \"John Doe\",\n  \"age\": \"30\"\n}",
  CURLOPT_HTTPHEADER => array(
    "Content-Type: application/json"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

使用Curl发送Patch请求

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "http://www.example.com/api/v1/patch",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "PATCH",
  CURLOPT_POSTFIELDS => "{\n  \"name\": \"John Doe\",\n  \"age\": \"30\"\n}",
  CURLOPT_HTTPHEADER => array(
    "Content-Type: application/json"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

PHP中可以使用Curl来发送Post、Get、Del、Put、Patch请求。Post、Get、Del、Put、Patch请求的使用方法大致相同，主要区别在于CURLOPT_CUSTOMREQUEST参数，分别是POST、GET、DELETE、PUT、PATCH。其他参数设置也稍有区别，例如Post请求需要设置CURLOPT_POSTFIELDS参数，Del请求不需要设置参数，Put请求也需要设置CURLOPT_POSTFIELDS参数，Patch请求也需要设置CURLOPT_POSTFIELDS参数。
