【问题描述】：

尝试在 RavenDb 中修补文档

$a = array('Patches' => array('pref_roles' => "1,2,3"),
                 'Key' => "Users/".$user_id,
                 'Method' => 'Patch'                
);

{"Patches":{"pref_roles":"1,2,3"},"Key":"Users/4","Method":"Patch"}

$input = json_encode($input);
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_CUSTOMREQUEST => 'POST',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_POSTFIELDS => $input,
    CURLOPT_URL => 'http://localhost:8080/databases/om/bulk_docs'
));
$resp = curl_exec($curl);

补丁永远无法通过。我哪里错了？

编辑。

在“脚本”中添加

$a = array('Patch' => array('Script' => 'this.natio = '.$natio.''),
           'Key' => 'Users/'.$user_id,
           'Method' => 'Patch');

我在发帖

CURLOPT_CUSTOMREQUEST => 'POST',

到这个网址：

CURLOPT_URL => 'http://localhost:8080/databases/om/bulk_docs'

带有这些错误消息：

)

玩了一会儿，看看我是否能找到可行的解决方案，但这并没有真正奏效。

以这种方式修补命令数据需要您通过实际操作。看： http://ravendb.net/docs/article-page/2.5/csharp/http-api/http-api-single

我建议你使用脚本补丁，使用 EVAL。

$a = array('Patch' => ('Script' => "this.pref_roles = [1,2,3["),
                 'Key' => "Users/".$user_id,
                 'Method' => 'Patch'                
);
