JWT Nedir ve Neden \u00d6nemlidir?<\/h3>\n

JSON Web Token (JWT), taraflar aras\u0131nda g\u00fcvenli bir \u015fekilde bilgi iletimini sa\u011flayan, kompakt ve URL g\u00fcvenli bir y\u00f6ntemdir. \u00d6zellikle API tabanl\u0131 sistemlerde kullan\u0131c\u0131 kimlik do\u011frulama ve yetkilendirme mekanizmalar\u0131nda yayg\u0131n olarak kullan\u0131l\u0131r. JWT’ler, bir sunucu taraf\u0131ndan olu\u015fturulur ve istemciye g\u00f6nderilir. \u0130stemci, sonraki isteklerinde bu token’\u0131 sunucuya geri g\u00f6ndererek kimli\u011fini kan\u0131tlar.<\/p>\n
