線上環境須要按期清理緩存,以下:
html
[root@LB scripts]# curl http://10.238.74.31/irm/manualDataSyncPage!synchronizeCrmGroupCustomerInfo.html?UserName=004&Password=ZHzg-123 shell
-bash: !synchronizeCrmGroupCustomerInfo.html?UserName=004: event not found緩存
「!」在平常命令中能夠做爲調用history歷史記錄來使用執行某行內容,在shell裏爲特殊字符。bash
在執行curl "http://10.238.74.31/irm/manualDataSyncPage!synchronizeCrmGroupCustomerInfo.html?UserName=004&Password=ZHzg-123"的過程當中,發現「!」沒法被正常解析,加上轉義反斜槓「\」也沒用。curl
[root@LB scripts]# curl http://10.238.74.31/irm/manualDataSyncPage\!synchronizeCrmGroupCustomerInfo.html?UserName=004&Password=ZHzg-123ide
-bash: !event not foundui
後發如今「!」先後加入空格能夠解決這個問題,但還不夠完美,由於輸入的文件字符也是加了空格後的,感受佔用較長地方,現象以下:url
[root@LB scripts]# curl "http://10.238.74.31/irm/manualDataSyncPage ! synchronizeCrmGroupCustomerInfo.htmlme=004&Password=ZHzg-123"spa
最後嘗試雙引號與反斜槓同時使用,完美解決問題!具體以下:htm
[root@LB scripts]# curl "http://10.238.74.31/irm/manualDataSyncPage"\!"syncronizeCrmGroupCustomerInfo.html?UserName=004&Password=ZHzg-123"

hexA0s = hexA0s + hexA0s + hexA0s + hexA0s;
