我的项目路劲如下

/data/wwwroot/test1/index.php
/data/wwwroot/test2/test2/index.php

location /test1 {
    root /data/wwwroot;
    fastcgi_pass $fast_cgi_sock;
    fastcgi_index index.php;
    include fastcgi.conf;
}   

location /test2 {
    root /data/wwwroot/test2;
    fastcgi_pass $fast_cgi_sock;
    fastcgi_index index.php;
    include fastcgi.conf;
#   echo $document_root$fastcgi_script_name;
#   echo $document_root;
#   echo $fastcgi_script_name;
}

你要把Js写在pjax里面，ps:不推荐使用pjax，之前有用过感觉坑太多

public function rules() {
    //parent::rules();
    return [
        [['keyword'],'match','pattern'=>'~\s+~','message'=>'请不要输入空格']
    ];
}

@开门_查水表 你想改错误提示信息，还是修改http reponse code?
