nginx blocking blank user agent .
sometime apps’ backgroud request always visit a url, and these requests’ user agent is black, so I want block them.
针对一个location的nginx配置
<code> location / {
<span>if</span> (<span>$http_user_agent</span> = <span>""</span>){
access_log off;
<span>return</span><span>403</span>;
}
default_<span>type</span> text/html;
content_by_lua <span>'
ngx.say("<h1>你好 baby </h1>")
'</span>;
}</code>模拟请求
<code>lzz<span>@ubuntu</span><span>:conf</span><span>$ </span>curl <span>'http://localhost'</span> <h1>你好 baby /h1></h1></code>
<code>lzz@ubuntu:conf$ curl -H "User-Agent:" 'http://localhost' <span>html</span>><span>head</span>><span>title</span>>403 Forbidden<span><span>title</span>></span><span><span>head</span>></span><span>body</span><span>bgcolor</span>=<span>"white"</span>><span>center</span>><span>h1</span>>403 Forbidden<span><span>h1</span>></span><span><span>center</span>></span><span>hr</span>><span>center</span>>ngx_openresty/1.2.6.1<span><span>center</span>></span><span><span>body</span>></span><span><span>html</span>></span></code>
