flutter masuk dengan apple di parse pendahuluan parse server mendukung otentikasi pihak ketiga dalam panduan ini, anda akan belajar bagaimana mendukung masuk dengan apple di aplikasi flutter anda di parse prasyarat untuk menyelesaikan tutorial ini, anda akan membutuhkan https //flutter dev/docs/get started/install https //developer android com/studio atau https //code visualstudio com/ (dengan https //docs flutter dev/get started/editor dart dan flutter) aplikasi flutter yang dibuat dan terhubung ke back4app catatan ikuti https //www back4app com/docs/get started/new parse app untuk belajar cara membuat aplikasi parse di back4app keanggotaan berbayar untuk https //developer apple com/programs/ siapkan plugin sign in with apple sign in with apple pada proyek sebuah perangkat (bukan simulator) yang menjalankan ios tujuan masuk dengan apple di aplikasi flutter pada parse server 1 tambahkan kemampuan masuk dengan apple ke proyek dasar ios anda buka ios/runner xcworkspace ios/runner xcworkspace di xcode periksa plugin sign in with apple sign in with apple petunjuk untuk mengatur masuk dengan apple masuk dengan apple di proyek ios anda pilih tim tim untuk proyek simpan dan tutup xcode 2 konfigurasi app id di portal pengembang masuk ke https //developer apple com/ anda dan pergi ke identifikasi identifikasi bagian periksa apakah bundle identifier bundle identifier yang anda buat ada di sana klik bundle identifier bundle identifier dan gulir ke bawah periksa apakah masuk dengan apple masuk dengan apple dipilih klik edit edit dan pastikan aktifkan sebagai app id utama aktifkan sebagai app id utama dipilih jika semuanya benar, simpan dan keluar 3 siapkan parse auth untuk apple kunjungi situs web back4app, masuk, dan kemudian temukan aplikasi anda setelah itu, klik pada pengaturan server pengaturan server dan cari blok login apple login apple dan pilih pengaturan pengaturan bagian login apple login apple terlihat seperti ini sekarang, anda hanya perlu menempelkan id bundle id bundle anda di kolom di bawah ini dan klik tombol untuk menyimpan jika anda mengalami kesulitan saat mengintegrasikan login apple, silakan hubungi tim kami melalui obrolan! 4 tambahkan masuk dengan apple sekarang anda telah menyiapkan proyek, kita bisa mendapatkan data pengguna dan masuk ke parse menurut dokumentasi, kita harus mengirimkan peta dengan data otentikasi pengguna 1 final credential = await signinwithapple getappleidcredential( 2 scopes \[ 3 appleidauthorizationscopes email, 4 appleidauthorizationscopes fullname, 5 ], 6 ); 7 8 //https //docs parseplatform org/parse server/guide/#apple authdata 9 //according to the documentation, we must send a map with user authentication data 10 //make sign in with apple 11 final parseresponse = await parseuser loginwith('apple', 12 apple(credential identitytoken!, credential useridentifier!)); 5 masuk dengan apple dari flutter mari kita gunakan contoh kita untuk masuk dengan apple di aplikasi flutter, dengan antarmuka yang sederhana buka proyek flutter anda, pergi ke file main dart, bersihkan semua kode, dan ganti dengan 1 import 'package\ flutter/material dart'; 2 import 'package\ parse server sdk flutter/parse server sdk dart'; 3 import 'package\ sign in with apple/sign in with apple dart'; 4 5 void main() async { 6 widgetsflutterbinding ensureinitialized(); 7 8 final keyapplicationid = 'your app id here'; 9 final keyclientkey = 'your client key here'; 10 final keyparseserverurl = 'https //parseapi back4app com'; 11 12 await parse() initialize(keyapplicationid, keyparseserverurl, 13 clientkey keyclientkey, debug true); 14 15 runapp(myapp()); 16 } 17 18 class myapp extends statelesswidget { 19 future\<bool> hasuserlogged() async { 20 parseuser? currentuser = await parseuser currentuser() as parseuser?; 21 if (currentuser == null) { 22 return false; 23 } 24 //checks whether the user's session token is valid 25 final parseresponse? parseresponse = 26 await parseuser getcurrentuserfromserver(currentuser sessiontoken!); 27 28 if (parseresponse? success == null || !parseresponse!
