下载好代码后，点击查询，缺没有任何反应，报错

我下载好代码后，点击查询，打开控制台，发现报了两个错，

XMLHttpRequest cannot load file:///C:/Users/dell/AppData/Local/Temp/360zip$Temp/360$3/server.php?number=. Cross origin requests are only supported for protocol schemes: http, data, chrome-extension, https, chrome-extension-resource. XMLHttpRequest.html:42

Uncaught NetworkError: Failed to execute 'send' on 'XMLHttpRequest': Failed to load 'file:///C:/Users/dell/AppData/Local/Temp/360zip$Temp/360$3/server.php?number='. XMLHttpRequest.html:42

是怎么回事
