API Pinterest重命名板名

Question

我对Pinterest API有问题。

我想重命名板。 我写下面的代码

$access_token = "removed";

function rename_board($access_token, $now_board_name, $new_board_name) {
    $url = 'https://api.pinterest.com/v1/boards/'.$now_board_name.'/?access_token='.$access_token;  

    $curlPost = 'board='.$now_board_name.'&name='.$new_board_name;
    $ch = curl_init();      
    curl_setopt($ch, CURLOPT_URL, $url);        
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);      
    curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);            
    $data = json_decode(curl_exec($ch), true);
    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); 
    curl_close($ch);    

    print "<br>";
    print $http_code;   
}   

rename_board($access_token, "1234", "AAA"); 

我得到一个错误：405
