爲什麼iPhone將Google Chrome視爲Safari還將Mozilla Firefox視爲Safari瀏覽器？

Question

我創建了一個代碼，用於檢查瀏覽器是否只能在Google Chrome上訪問並限制Mozilla Firefox。例如，我使用的只是使用谷歌瀏覽器的Android手機，如果iPhone或iPad Google Chrome瀏覽器有權訪問該網站。但是，當檢查瀏覽器是Chrome還是Mozilla時，它會被視爲Safari。使用C＃，工具。所以我調查它是否有一個獨特的財產，很好用，但可悲的是沒有。有沒有一個好的插件或庫或框架來檢測iPhone或Android瀏覽器。謝謝。

這是用於谷歌瀏覽器。

var userAgent = filterContext.HttpContext.Request.UserAgent?.ToLowerInvariant() ?? ""; 
"mozilla/5.0 (iphone; cpu iphone os 9_1 like mac os x) applewebkit/601.1.46 (khtml, like gecko) version/9.0 mobile/13b143 safari/601.1" 

var userBrowser = filterContext.HttpContext.Request.Browser.Browser?.ToLowerInvariant() ?? ""; 
"safari" 

var userBrowserTypeype = filterContext.HttpContext.Request.Browser.Type; 
"Safari9" 

var userBrowserVersion = filterContext.HttpContext.Request.Browser.Version; 
"9.0" 

var userBrowserMajorVersion = filterContext.HttpContext.Request.Browser.MajorVersion; 
"9" 

var userBrowserMinorVersion = filterContext.HttpContext.Request.Browser.MinorVersion; 
0 

var userBrowserPlatform = filterContext.HttpContext.Request.Browser.Platform; 
"Unknown" 

var userBrowserBeta = filterContext.HttpContext.Request.Browser.Beta; 
false

true 

var userBrowserCookies = filterContext.HttpContext.Request.Browser.Cookies; 
true 

var userBrowserVbScript = filterContext.HttpContext.Request.Browser.VBScript;

這是用於Mozilla Firefox的。

var userBrowser = filterContext.HttpContext.Request.Browser.Browser?.ToLowerInvariant() ?? ""; 
"safari" 

var userBrowserTypeype = filterContext.HttpContext.Request.Browser.Type; 
"Safari10" 

var userBrowserVersion = filterContext.HttpContext.Request.Browser.Version; 
"10.0" 

var userBrowserMajorVersion = filterContext.HttpContext.Request.Browser.MajorVersion; 
"10" 

var userBrowserMinorVersion = filterContext.HttpContext.Request.Browser.MinorVersion; 
0 

var userBrowserPlatform = filterContext.HttpContext.Request.Browser.Platform; 
"Unknown" 

var userBrowserBeta = filterContext.HttpContext.Request.Browser.Beta; 
false

false 

var userAol = filterContext.HttpContext.Request.Browser.AOL; 
false 

var userBrowserWin16 = filterContext.HttpContext.Request.Browser.Win16; 
false 

var userBrowserWin32 = filterContext.HttpContext.Request.Browser.Win32; 
false 

var userBrowserFrames = filterContext.HttpContext.Request.Browser.Frames; 
true 

var usBrowserTables = filterContext.HttpContext.Request.Browser.Tables; 
true 

var userBrowserCookies = filterContext.HttpContext.Request.Browser.Cookies; 
true 

var userBrowserVbScript = filterContext.HttpContext.Request.Browser.VBScript; 
false

這可能是由於iOS不允許其他瀏覽器引擎比Safari。

不幸的是，這迫使Chrome應用程序使用Safari的Web瀏覽器組件和用戶代理。
