如何用php模拟json请求

只需设置header头

$url ="http://www.test.com/articles/_search?size=10&from=$from";
$json_data = json_encode ( $params );
$json_data = "{'name':'test'}";
$result =  curl ( $url, $json_data, "GET" );

function curl($url, $postDate = "", $method = "PUT") {
    //echo "url=>".$url."<br>";
    $ci = curl_init ();
    $headers = array(
        "Content-type: application/json;charset='utf-8'",
        "Accept: application/json",
        "Cache-Control: no-cache",
        "Pragma: no-cache",
    );
    curl_setopt ( $ci, CURLOPT_URL, $url );
    curl_setopt ( $ci, CURLOPT_PORT, 10026 );
    curl_setopt ( $ci, CURLOPT_TIMEOUT, 200 );
    curl_setopt ( $ci, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $ci, CURLOPT_FORBID_REUSE, 0 );
    curl_setopt ( $ci, CURLOPT_CUSTOMREQUEST, $method );
    curl_setopt($ci, CURLOPT_HTTPHEADER, $headers);
    if ($postDate) {
        curl_setopt ( $ci, CURLOPT_POSTFIELDS, $postDate );
    }
    $response = curl_exec ( $ci );
    return $response;
}
