ฉันกำลังทำมันโดยใช้ตัวดัก ฉันสร้างไฟล์ไลบรารีที่สามารถเพิ่มลงในไฟล์ index.html ได้ วิธีนี้คุณจะสามารถจัดการข้อผิดพลาดทั่วโลกสำหรับการโทรหาบริการส่วนที่เหลือและไม่ต้องสนใจข้อผิดพลาดทั้งหมด ยิ่งไปกว่านั้นฉันยังวางไลบรารี่การล็อกอินขั้นพื้นฐานของฉันไว้ด้วย ที่นั่นคุณจะเห็นว่าฉันยังตรวจสอบข้อผิดพลาด 401 และเปลี่ยนเส้นทางไปยังตำแหน่งอื่น ดู lib / ea-basic-auth-login.js
