Python socket pilih contoh klien

Perhatikan bahwa jika terjadi kesalahan selama pembuatan soket, maka soket. kesalahan dilemparkan dan kami hanya dapat terhubung ke server dengan mengetahui IP-nya. Anda dapat menemukan IP server dengan menggunakan ini.  

$ ping www.google.com

Anda juga dapat menemukan IP menggunakan python.  

import socket 

ip = socket.gethostbyname('www.google.com')
print ip

Berikut adalah contoh skrip untuk menghubungkan ke Google

  • Pertama-tama, kami membuat soket
  • Kemudian kami menyelesaikan IP google dan terakhir, kami terhubung ke google
  • Sekarang kita perlu tahu bagaimana cara mengirim beberapa data melalui soket
  • Untuk mengirim data, perpustakaan soket memiliki fungsi sendall. Fungsi ini memungkinkan Anda mengirim data ke server tempat soket terhubung dan server juga dapat mengirim data ke klien menggunakan fungsi ini

Program server-klien sederhana.   

Server.  

Server memiliki metode bind() yang mengikatnya ke IP dan port tertentu sehingga dapat mendengarkan permintaan masuk pada IP dan port tersebut. Server memiliki metode listen() yang menempatkan server ke mode mendengarkan. Hal ini memungkinkan server untuk mendengarkan koneksi masuk. Dan terakhir server memiliki metode accept() dan close(). Metode accept memulai koneksi dengan klien dan metode close menutup koneksi dengan klien.

  • Pertama-tama, kami mengimpor soket yang diperlukan
  • Kemudian kami membuat objek soket dan memesan port di komputer kami
  • Setelah itu, kami mengikat server kami ke port yang ditentukan. Melewati string kosong berarti server juga dapat mendengarkan koneksi masuk dari komputer lain. Jika kita akan melewati 127. 0. 0. 1 maka hanya akan mendengarkan panggilan yang dilakukan di dalam komputer lokal
  • Setelah itu kami menempatkan server ke mode mendengarkan. 5 di sini berarti 5 koneksi tetap menunggu jika server sedang sibuk dan jika soket ke-6 mencoba terhubung maka koneksi ditolak
  • Akhirnya, kami membuat while loop dan mulai menerima semua koneksi masuk dan menutup koneksi tersebut setelah pesan terima kasih ke semua soket yang terhubung

Klien.  
Sekarang kita membutuhkan sesuatu yang dapat berinteraksi dengan server. Kami dapat melakukan telnet ke server seperti ini hanya untuk mengetahui bahwa server kami berfungsi. Ketik perintah ini di terminal.  

# start the server
$ python server.py

# keep the above terminal open 
# now open another terminal and type: 
 
$ telnet localhost 12345

Jika 'telnet' tidak dikenali. Di windows cari fitur windows dan aktifkan fitur "klien telnet".

Bagaimana cara menghubungkan klien ke server menggunakan soket di python?

Untuk menggunakan koneksi soket python, kita perlu mengimpor modul soket. Kemudian, secara berurutan kita perlu melakukan beberapa tugas untuk membuat koneksi antara server dan klien . Kita bisa mendapatkan alamat host dengan menggunakan socket. fungsi gethostname().

Bagaimana cara pilih pilih bekerja di python?

Fungsi select() Python adalah antarmuka langsung ke implementasi sistem operasi yang mendasarinya. Ini memonitor soket, file terbuka, dan pipa (apa pun dengan metode fileno() yang mengembalikan deskriptor file yang valid) hingga menjadi dapat dibaca atau ditulis, atau terjadi kesalahan komunikasi.

Bagaimana Anda menentukan soket TCP dengan python?

Dimulai dengan membuat soket TCP/IP. .
impor soket impor sys # Buat soket TCP/IP sock = soket. soket (soket. .
# Ikat soket ke port server_address = ('localhost', 10000) print >>sys. stderr, 'memulai pada %s port %s' % server_address sock. .
# Dengarkan kaus kaki koneksi yang masuk

Bagaimana Anda membuat soket klien dengan python?

Klien soket sederhana Python .
membuat soket
dapatkan alamat ip server dari nama domain
terhubung ke server menggunakan alamat ip
kirim permintaan ke server
menerima data (halaman web) Dalam kode yang akan terlihat seperti. # Contoh klien soket dengan python. soket impor. impor sistem. tuan rumah = 'www. bahasa pemrograman python. com' port = 80 # web
