redirect nginx gagal jika permintaan asal tidak wujud

Question

Pernyataan Masalah: nginx nampaknya tidak mengubah hala apabila permintaan asal adalah ke lokasi yang tidak wujud. Semua ubah hala lain nampaknya berfungsi dengan baik. Ia juga mungkin bahawa php tidak melaksanakan skrip pada halaman yang diubah hala. nginxconf disediakan di bawah.

Soalan: Apa yang saya hilang dan apakah yang perlu saya lakukan untuk membuat kerja ini? Adakah mungkin nginx tidak menyokong pengalihan dari halaman yang tidak wujud?

Sesetengah konteks mungkin membantu: Berikut ialah permintaan biasa yang diubah hala:

73.234.24.22 - - [30/May/2022:16:15:05 +0000] "GET /postevent3.asp?dta=05%2f30%2f22%2016%3a15%3a22%20507%20%2b149642656%20%2d254084882%20%2d0001787%20682829361 HTTP/1.1" 302 154 "-" "-"

Perhatikan bahawa tiada halaman dipaparkan untuk permintaan ini; Lihat penghujung artikel ini untuk petikan daripada log nyahpepijat nginx.

Menukar URL adalah tidak praktikal kerana terdapat berpuluh-puluh unit yang tersebar di seluruh dunia. Kebanyakan peranti tidak boleh dikemas kini dari jauh.

Tapak asal tidak lagi digunakan, menggunakan apache. Tapak semasa menggunakan nginx. Saya tidak begitu biasa dengan pelayan web, jadi saya mungkin kehilangan sesuatu yang jelas. Semua idea akan dihargai.

Saya juga mencuba perkara berikut dalam blok pelayan port 80:

location / {
    try_files $uri $uri/ /data/submit_legacy.php?$query_string;
}

Answer 1

Jika tekaan saya bahawa perisian yang membuat permintaan ini tidak dapat mentafsir kod ubah hala 302 HTTP dan membuat permintaan baharu adalah betul, maka satu-satunya jalan anda ialah mengendalikan permintaan dalam blok HTTP itu sendiri. bukannya semasa anda

location = /postevent3.asp {
    return 302 https://example.org/data/submit_legacy.php?$query_string; 
}       

Anda boleh menyemak konfigurasi ini:

location = /postevent3.asp {
    rewrite ^ /data/submit_legacy.php break;
    include fastcgi_params;
    fastcgi_param SCRIPT_FILENAME $document_root$uri;
    fastcgi_pass unix:/run/php/php7.4-fpm.sock;
}

Jika anda menggunakan konfigurasi ini, permintaan anda akan mula dipaparkan dalam pangkalan data, yang pastinya bermakna tekaan awal saya betul.
