JSON ওয়েব টোকেন (JWT) এর সাথে কাজ করা

JSON ওয়েব টোকেনগুলি একটি JSON অবজেক্ট হিসাবে নিরাপদে তথ্য স্থানান্তর করার জন্য একটি সাধারণভাবে ব্যবহৃত শিল্প মান। Google Wallet API ব্যবহার করার সময়, আপনি JWT (উচ্চারিত "jot") ফর্ম্যাটে একটি পাস ইন্সট্যান্স তৈরি করতে যে পাসস অবজেক্ট ব্যবহার করতে চান তার বিবরণ এনকোড করেন, তারপর সেই JWTটিকে Google Wallet API-কে অনুরোধ করে পাঠান।

JWT গুলিকে Google Wallet API-এ পাঠানোর আগে একটি শেয়ার করা গোপনীয়তার সাথে স্বাক্ষর করে সুরক্ষিত রাখা হয়। আপনি যদি Google Wallet REST API ব্যবহার করেন, তাহলে স্বাক্ষর করার গোপনীয়তা হল আপনার Google ক্লাউড পরিষেবা অ্যাকাউন্ট কী৷ আপনি যদি Google Wallet Android SDK ব্যবহার করেন, তাহলে সাইনিং সিক্রেট হল আপনার Android অ্যাপের জন্য SHA-1 ফিঙ্গারপ্রিন্ট৷

একটি JWT এ একটি পাস এনকোড করুন

যখন TransitObject তৈরি করা হয়, তখন payload.TransitObjects সাথে একটি স্বাক্ষরবিহীন JWT দিয়ে এটিকে মুড়ে দিন।

ওয়েব, ইমেল এবং এসএমএস

আপনি Google Wallet বিজনেস কনসোলে অনুমোদিত Google ক্লাউড পরিষেবা অ্যাকাউন্টের সাথে যুক্ত পরিষেবা অ্যাকাউন্ট কী ব্যবহার করে JWT স্বাক্ষর করতে হবে। Google Wallet API JWT স্বাক্ষর যাচাই করে এই দাবিগুলিকে যাচাই করবে৷

JWT-এ স্বাক্ষর করা একটি টোকেন তৈরি করবে যা তারপর একটি 'Google Wallet-এ যোগ করুন' লিঙ্ক তৈরি করতে ব্যবহার করা যেতে পারে যা ব্যবহারকারীকে পাস ইস্যু করতে ব্যবহার করা যেতে পারে:

অ্যান্ড্রয়েড অ্যাপস

যখন কোনো ব্যবহারকারীকে পাস ইস্যু করার জন্য savePasses পদ্ধতিতে কল করা হয়, তখন Google Wallet Android SDK স্বয়ংক্রিয়ভাবে আপনার JWT-এ আপনার অ্যাপ সাইনিং কী-এর SHA-1 ফিঙ্গারপ্রিন্ট দিয়ে স্বাক্ষর করে যা আপনি Google Wallet Business Console-এ প্রদান করেছেন। বিকল্পভাবে, আপনি Android SDK-এর savePassesJwt পদ্ধতি ব্যবহার করে পূর্বে স্বাক্ষরিত JWT ব্যবহার করে পাস ইস্যু করতে পারেন।

আরও তথ্যের জন্য, Android SDK-এর সাথে পাস ইস্যু করা দেখুন।
