Nginx别名配置嵌套位置，带有PHP Slim和Laravel的try_files参数错误

Question

server {
    listen 80;
    client_max_body_size 3M;
    root    /var/www/html/project/project_bb/public;
    index   index.php index.html index.htm;

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;

            fastcgi_read_timeout 300;
            add_header Access-control-Allow-Origin *;
            include fastcgi_params;
    }

    location ~/testfolder/ {
        try_files $uri $uri/ /testfolder/index.html;
    }

      location /test {
        alias /var/www/html/project/testfolder;
    }

    location /api {
        alias /var/www/html/project/apiclient_project/public;
        location ~ \.php$ {
            try_files $uri =404;
            fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
            #fastcgi_pass 127.0.0.1:9000;

            fastcgi_param APPLICATION_ENV dev;
            fastcgi_param PHP_VALUE "date.timezone=Asia/Kolkata";
            fastcgi_read_timeout 300;
            #include fastcgi_params;
        }

       try_files $uri $uri/ ~/index.php?$args;


        location ~ /\.ht {
            deny all;
        }
    }

    location  /. { ## Disable .htaccess and other hidden files
        return 404;
    }

    location / {
       try_files $uri $uri/ /index.php?$args;
    }

}

我在laravel项目中嵌套了一个苗条的框架，我需要设置nginx配置，使得project / api应该是别名，当前我正在使用代理。在传递try_files时传递错误论点，因为苗条的框架无法在嵌套位置传递或获取api的论点，请让我知道是否需要更改
