报错问题1

[AmShadows]

Start 40 Spider... Spider OK

panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x40 pc=0x68fc89]

goroutine 1 [running]: github.com/pingc0y/URLFinder/util.GetProtocol({0xc0000d09f0, 0x22}) /home/runner/work/URLFinder/URLFinder/util/utils.go:122 +0xc9 github.com/pingc0y/URLFinder/crawler.Run() /home/runner/work/URLFinder/URLFinder/crawler/run.go:138 +0x990 main.main() /home/runner/work/URLFinder/URLFinder/main.go:15 +0x37

例如我使用-s all -m 3 -d "***.cn" -ff all.txt -o result.html，当跑了十几个后中间遇到一个无法访问或者302的url跳转时就会以上报错。
