Ama-callback okubhala e-PHP cURL kufanele abuyisele inani lamabhayithi asetshenziwe

I-proxy iletha idatha. I-callback yakho yokubhala ibuyisela inani elingalungile. Khona-ke i-libcurl iyama, futhi ikhodi ezungezile ibika “ukwehluleka kokulanda nge-proxy” okunye.

I-callback kufanele ibike ukuthi mangaki amabhayithi atholiwe eyawasetshenzisa ngempela. Ukubuyisela enye inombolo kukhombisa ukwehluleka. Esikhaleni sokubhala esivimbela ngamabomu, ucezu lungabukeka kanje:

curl_setopt($handle, CURLOPT_PROXY, 'http://proxy.example:8080');
curl_setopt($handle, CURLOPT_WRITEFUNCTION,
    function ($handle, $chunk) use ($sink) {
        $written = fwrite($sink, $chunk);
        return $written === false ? 0 : $written;
    }
);

Lokhu kucabanga ukuthi uhlelo olukhona lungumnikazi we-handle nendawo yokubhala. Ukubhala okwehlulekile noma okufushane kuyama esikhundleni sokusho buthule ukuthi lonke ucezu lulondoloziwe. Indawo engavimbeli idinga umklamo ofanele wokugcina kanye nokumisa/ukuqhubeka; ucezu oluncane alunikezi lolo.

Bala amabhayithi, hhayi izinhlamvu ezibonisiwe. Idatha ingaba yi-binary noma ingxenye yokulandelana kombhalo wamabhayithi amaningi. I-callback eyodwa ayidingeki ukuba ibe umugqa owodwa, idokhumenti ye-JSON eyodwa noma umlayezo ovela kusevisi.

Ukuhlaziya okwandayo kudinga isimo sako phakathi kwama-callback. Ngokuphambene, ukuqoqa ucezu ngalunye kuze kuphele kungase kulunge empendulweni encane enomkhawulo, kodwa akusona isu lememori emfudumalweni omkhulu noma ongapheli.

Gcina umphumela wokudlulisela kanye nobufakazi bokwehluleka kwe-callback. Iphutha lediski lendawo noma ukuma kwe-parser kungenzeka ngemva kokusungulwa komzila we-proxy ovumelekile. Uma uhlose ukuma ngemva kwe-prefix, maka ngokwehlukile lokho kuma okwe-callback okuhlosiwe. Ukushintsha ikheli le-proxy akukwazi ukulungisa indawo eye yeka ukwamukela idatha.
