Mengenai Helaian Rujukan cURL

Helaian rujukan curl ini ialah rujukan kerja untuk alat command-line HTTP yang paling berguna: asas, kaedah HTTP, header, menghantar data, pengesahan (authentication), memuat turun dan memuat naik, kuki, TLS/SSL, proksi, debugging dan output, serta had masa dan cubaan semula.

curl mempunyai beratus-ratus flag dan setiap orang hanya mengingati kira-kira sepuluh daripadanya. Setiap baris menunjukkan satu arahan lengkap — POST JSON, pengatasan header, muat turun yang boleh disambung semula, jabat tangan TLS verbose — dengan penerangan satu baris, supaya anda boleh mengangkat mantera yang tepat dan bukannya membaca man page semasa debugging.

Helaian ini percuma dan di sisi klien: tapis arahan secara langsung dengan kotak carian, lompat antara bahagian dari jadual kandungan yang melekat, salin mana-mana arahan dengan satu klik dan cetak halaman untuk sesi debugging API.

Cara menggunakan Helaian Rujukan cURL

  1. Imbas bahagian-bahagian, dari Asas dan Kaedah HTTP hingga Debugging & output dan Had masa & cubaan semula.
  2. Cari flag atau tugas seperti POST, header atau proxy untuk menapis arahan serta-merta.
  3. Lompat ke bahagian seperti Pengesahan atau TLS / SSL melalui bar sisi yang melekat.
  4. Klik arahan atau ikon salinnya untuk menyalinnya, kemudian gantikan URL dan nilai contoh.
  5. Cetak helaian untuk menyimpan rujukan curl di sebelah terminal anda.

Soalan lazim

Sebelas bahagian: asas, kaedah HTTP, header, menghantar data dan borang, pengesahan, muat turun dan muat naik, kuki, TLS/SSL, proksi, debugging dan output, serta had masa dengan cubaan semula.

Ya. Bahagian menghantar data menyertakan arahan siap pakai untuk menghantar JSON dan data borang dengan header yang betul, antara arahan curl yang paling kerap disalin.

Ya. Bahagian debugging dan output merangkumi mod verbose, pemeriksaan respons dan kawalan output, dan bahagian TLS membantu apabila kegagalan berkaitan sijil.

Ya. Klik arahan atau ikon salinnya dan panggilan curl yang lengkap berada pada papan klip anda — gantikan dengan URL, header dan data anda sendiri.

Ya, ia percuma, boleh dicari, boleh dicetak dan berjalan sepenuhnya dalam pelayar anda.
