Nginx未知指令"set"

Question

我有一个问题与nginx配置。当我运行nginx conftest时，我得到错误信息nginx: [emerg] unknown directive "    set"

nginx -V

这是我设置图片大小的位置，设置$ok会导致问题。

#images
location ~* ^/restapi/rest/d+/images/ {
    set $ok "no";
 
    # request parsing
    # possible values:
    #   <without query parameters>
    #   h32, h64, h96, h128, h192, h256, h320, h384, h512, h720, h1080
    #   w32, w64, w96, w128, w192, w256, w320, w384, w512, w720, w1920
    if ($args ~ ^((w|h)(32|64|96|128|192|256|320|384|512|720)|w1920|h1080)?$) {
        set $ok "yes";
    }
 
    if ($ok = "no") {
        return 404;
    }
 
    proxy_pass http://resizer;
    proxy_cache_methods GET;
    proxy_cache mycache;
    proxy_cache_valid 200 302 15m;
    proxy_cache_key $uri$is_args$args;
    proxy_cache_lock on;
    proxy_cache_lock_timeout 30s;
    proxy_cache_use_stale updating;
}

谁能告诉我我错过了什么?

nginx: [emerg] unknown directive " set"

带引号的部分正是nginx试图使用的指令名。显然有一些不应该出现的角色。最常见的错误是从一些网页中复制文本，这些网页倾向于使用不可分割的空格来缩进。
