Question

我试图在新窗口中打开pdf文件并在打开窗口后打开打印对话框，但是打开打印对话框的print（）方法被跨域阻止，因为conslole向我返回此错误DOMException ：阻止了来源为“ http://localhost:4200”的框架访问跨域框架。我该如何解决这个问题？

ip_list = []
server_list = []
while True:
    try:
        server = (input('> '))
        if server == 'q':
            break
        ip_addr = socket.gethostbyname(server)
        ip_list.append(ip_addr)
        server_list.append(server)
    except socket.gaierror:
        print(server, 'can\'t find server/ip', '\n')

print(ip_list)
print(server_list)

  print() {
            var myWindow = window.open('https://mediasb.shiftinc.com/booking_pdfs/QALNHF.pdf', 'Booking', 'width=600,height=600');
       myWindow.print();
      myWindow.focus();
    }

以角度：-

this.http.get('https://mediasb.shiftinc.com/booking_pdfs/QALNHF.pdf', {responseType: 'blob'}).subscribe((res) => {
        let url = window.URL.createObjectURL(res);
        var myWindow = window.open(url, 'Booking', 'width=600,height=600');
       myWindow.print();
      myWindow.focus();
});
