Go 1.11 telah mencapai akhir dukungan
dan akan dihentikan penggunaannya
pada 31 Januari 2026. Setelah penghentian penggunaan, Anda tidak akan dapat men-deploy aplikasi Go 1.11, meskipun organisasi Anda sebelumnya menggunakan kebijakan organisasi untuk mengaktifkan kembali deployment runtime lama. Aplikasi Go 1.11 yang ada akan terus berjalan dan menerima traffic setelah tanggal penghentiannya. Sebaiknya Anda bermigrasi ke Go versi terbaru yang didukung.
Library yang dapat menerima net.Conn seharusnya berfungsi tanpa modifikasi.
Pembatasan dan batasan
Dukungan socket di App Engine memiliki batasan berikut:
Anda tidak dapat membuat soket pemrosesan; Anda hanya dapat membuat soket keluar.
FTP tidak didukung.
Anda hanya dapat menggunakan TCP atau UDP; protokol arbitrer tidak diperbolehkan.
Anda tidak dapat terikat pada alamat IP atau port tertentu.
Port 25 (SMTP) diblokir; Anda masih dapat menggunakan SMTP yang diautentikasi pada
port pengiriman 587.
Rentang IP pribadi, siaran, multicast, dan Google diblokir, kecuali yang tercantum di bawah:
Google Public DNS: 8.8.8.8, 8.8.4.4, 2001:4860:4860::8888,
2001:4860:4860::8844 port 53
SMTP Gmail: smtp.gmail.com port 465 dan 587
POP3S Gmail: pop.gmail.com port 995
IMAPS Gmail: imap.gmail.com port 993
Deskripsi soket dikaitkan dengan aplikasi App Engine yang
membuatnya dan tidak dapat ditransfer (tidak dapat digunakan oleh aplikasi lain).
Soket dapat digunakan kembali setelah 10 menit dalam kondisi tidak aktif; operasi soket apa pun akan
menjaga soket tersebut tetap aktif selama 10 menit lagi.
Menggunakan soket dengan server pengembangan
Anda dapat menjalankan dan menguji kode menggunakan soket di server pengembangan, tanpa menggunakan
parameter command line khusus.
